Time out for time outs: Why pediatricians now promote ‘positive parenting’

Canadian Paediatric Society calls for shift away from shaming, blaming and other types of negative discipline

The latest parenting advice from Canada’s pediatricians is to shift away from shaming, blaming and any other types of negative discipline to what they call positive parenting.

Positive parenting is a set of principles to correct children’s misbehaviour with greater empathy and communication and less punishment — and sticking with it at the times when it’s most challenging. Experts say positive parenting fosters loving, predictable and secure relationships between a child and their parent or guardian.

The Canadian Paediatric Society (CPS) said in its latest position statement, released Thursday, that this is the first time it is asking all primary care practitioners to encourage positive parenting. Doing so, the society says, buffers against the effects of stressors and traumatic events.

Gold-standard randomized trials have demonstrated how positive parenting techniques are more effective at reducing negative behaviour in children, said Jenny Jenkins, the Atkinson Chair of Early Child Development and Education at the University of Toronto. Jenkins, a clinical and developmental psychologist, wasn’t involved in the position statement.

“Negative comments, negativity or harshness towards children has been shown to be much more problematic developmentally for kids,” Jenkins said.

‘Pick their battles’

Positive parenting techniques provide a better relationship between parents and children.

“Rather than parents getting mad at kids and being irritable with them and negative with them, the interaction becomes a more positive one,” she said.

If parents ignore the low-level problematic things that kids often do and intervene only when there’s a safety concern or really bad behaviour, then their interactions with a child can shift in a more positive direction.

“The parents are trying to pick their battles,” Jenkins said.

But today’s parents may be at a loss on how to practise positive parenting since many of their parents didn’t use it with them, said Dr. Andrea Feller, a member of the CPS’s early years task force that wrote the position statement.

Past parenting advice was well intentioned and based on what was known at the time, she said. But experts in child brain development no longer recommend discipline that includes punishments like shaming and blaming.

Experts say positive parenting fosters loving, predictable and secure relationships between a child and their parent or guardian. the Canadian Paediatric Society, in a new position statement, is for first time asking all primary care practitioners to encourage positive parenting.

Feller encourages parents who feel conflicted between the way they were raised and adopting positive parenting to trust themselves.

“Parents are a child’s first, best and most important teacher,” said Feller,a pediatrician in the Niagara Region and a mother of two children under 12.

In fact, the CPS said the reason behind the new statement is that while there are many factors that can put kids at risk for developmental problems, parenting is one that can be easily changed. The focus is on children aged zero to six years.

Time outs ‘have a place’ but should not be used to discipline children under the age of three, who only understand that a parent or caregiver has turned them away, says Dr. Andrea Feller of the Canadian Paediatric Society. 

 

Recommendations to doctors

One way parents can get guidance is at the doctor’s office. The CPS is encouraging pediatricians and family doctors to be comfortable asking parents about their relationship with a child and how well the family is coping.

At every visit, clinicians should ask questions about a child’s behaviours and family routines, such as “What is your child’s bedtime routine?”

Parents of young children commonly ask doctors for advice on crying, sleep and challenging behaviours, so that could serve as an opening for those types of conversations.

Clinicians are also encouraged to broach difficult and sometimes uncomfortable topics, such as trauma, and ask questions like “Has anything stressful happened to you or your family since I last saw you?”

To promote positive parenting behaviours, the society’s other recommendations to clinicians include:

  • Ask if there is a consistent caregiver, since that is a protective factor.
  • Model communication skills by being open, predictable, kind and curious.
  • Promote shared reading by families.
  • Incorporate family-friendly hours and proactive scheduling into their practice (e.g. “Let’s make an appointment for early next month” versus “Come back if you’re having difficulties.”)

Primary care providers can also direct parents to positive parenting books or free community supports such as local early years centres.

Shift to time ins

The document also included a section on time outs and time ins.

A time out creates a brief break in the child’s behaviours, even if it’s a positive one such as expressing curiosity or reaching for a hug. In a time in, on the other hand, the caregiver invites the child to sit and talk about feelings and behaviour in an age-appropriate way.

“Time outs have a place,” Feller said, but should be considered a “last resort,” since time outs can drift inappropriately into punishment.

What’s more, time outs have no place in disciplining children under the age of three, who only understand that a parent or caregiver has turned them away. Often, Feller added, it is the parent who needs a break.

Feller noted social workers and early childhood educators already encourage positive discipline.

Now medical professionals are making the shift toward helping parents recognize that a young child’s misbehaviour is often a way for them to communicate: “I can’t handle things right now. I need your help.”

Pediatrician Daniel Flanders, founder and director of Kindercare Pediatrics in Toronto, said the position statement is reasonable.

“It’s a positive step in right direction, but it’s a really small one,” Flanders said. What’s missing is practical ways to help parents implement it.

“It’s all fair and good to say this is how parents should parent, but it’s a whole other ball game when a single mom is trying to make it through the day, and she doesn’t really have any resources or any support to really help her parent in all the ways this position statement is encouraging.”

Does sugar make kids hyper? That’s largely a myth

Does sugar make kids hyper? Maybe.

The idea of a link between sugar and hyperactivity in children dates to the 1970s, when the Feingold diet was prescribed by a pediatrician with the same name as an eating plan to alleviate symptoms of ADHD.

“His diet eliminated artificial flavorings, sweeteners and preservatives — and so sugar kind of got lumped in, as well,” King said.

This diet may have led parents to perceive that sugar is a culprit when it comes to kids’ excitable behavior — even if it is not the true cause of one’s hyperactivity.

In one study from the mid-’90s, researchers gave children a drink containing a sugar substitute. One group of moms was told that their kids were drinking a high-sugar drink; the other group was told the truth, that their kids were consuming a sugar substitute. Mothers who were told that their kids consumed sugar rated their kids as more hyperactive, even though they didn’t consume any sugar.

“Just thinking their children were consuming sugar caused moms to perceive their children as being more hyperactive,” King said.

“When children consume sugar, it’s usually around something fun: holidays, birthdays, celebrations; there’s already that excitement there,” she said. “I don’t think you can say the sugar made them run around and play with friends. … That would be very hard to separate out.”

Instead, a release of the hormone adrenaline might explain a child’s overly energetic behavior. “It’s a flight or flight hormone; when you are excited or fearful, it increases heart rate and directs blood flow to the muscles, which may make children more antsy and have the urge to keep moving, so you may be perceiving that as hyperactivity,” King said.

“If you look at the peer-reviewed evidence, we cannot say sugar absolutely makes kids hyper; however, you can’t discount that sugar may have a slight effect” on behavior, said Kristi L. King, senior pediatric dietitian at Texas Children’s Hospital and spokeswoman for the Academy of Nutrition and Dietetics.
In the mid-1990s, a meta-analysis reviewed 16 studies on sugar’s effects in children. The research, published in the medical journal JAMA, concluded that sugar does not affect behavior or cognitive performance in children. “However, a small effect of sugar or effects on subsets of children cannot be ruled out,” the article said.
Like adults, some children may be more sensitive to blood sugar spikes than others. This may mean they are more likely to become aroused when consuming sugar.
Notably, a small percentage of children with attention-deficit hyperactivity disorder may be extra sensitive to sugar, and their behavior changes when they eat it, according to Jill Castle, a registered dietitian and childhood nutrition expert who teaches a parenting course called the ADHD Diet for Kids. “They may become more aggressive or hyperactive or difficult to parent,” Castle explained. Minimizing sugar in the diet can be beneficial for these children.

According to Castle, lots of sugary foods can also equate to elevated amounts of food dyes, artificial flavors or other additives that could be problematic for a child with ADHD, often making it difficult to tease out whether sugar is the culprit.Complicating the issue is the fact that we don’t have a way to determine whether there is a link. “Is there a biomarker? A hormone level?” King asked. “It’s disheartening for parents. … They want answers. And unfortunately, nutrition is such an individual thing.”

 

Sugar and hyperactivity: Positive link or parent perception?

To try to determine whether your child is truly sugar-sensitive or just excited about a celebration, Castle recommends eliminating sugary foods from the diet for a few weeks and then testing the child with a sugary food like soda, frosted cake or a tablespoon of sugar in 100% juice, and watching the child’s response. “It may be a quick way to determine how sugar may be affecting the child,” Castle said.

Then again, like the parents in that study, you may just think they’re being hyper just because you know that they consumed sugar.

Tips for parents

Even though most kids don’t have a sugar sensitivity, that doesn’t mean sugar is good for their health. Sugary foods and beverages deliver calories without any nutrients. What’s more, eating foods high in added sugars throughout childhood is linked to the development of risk factors for heart disease, such as an increased risk of obesity and elevated blood pressure in children and young adults.

To keep kids healthy, the American Heart Association recommends that children ages 2 to 18 consume less than 6 teaspoons – or 24 grams – of added sugars daily. To put that number in perspective, consider that 24 grams is the amount of sugar in just one 1.55-ounce chocolate bar. A 12-ounce can of regular soda contains about 40 grams of sugar, well over a day’s worth.

If you are looking for ways to cut back on sweets for your children, here are some tips to get started:

Gradually reduce the amount of sweets in your child’s diet. This is good advice for all kids, with and without ADHD. “I teach the 90/10 Rule for the appropriate balance of nourishing foods and sweets and treats, which equates to one to two normal-sized portions of sweets or treats each day, on average,” Castle said. If there seems to be a strong sensitivity to sweets, Castle recommends removing sweets and added sugar from the diet as best as you can.

Establish routine meals and snacks on a predictable schedule. “Anecdotally, this is one of the main things I work on with families, and they tell me they feel their child is calmer and better-behaved. There is something to be said for nourishing the brain and body on predictable, consistent intervals of three to four hours,” Castle said.

When introducing foods with added sugars, pair them with protein, healthy fat or fiber. This helps to blunt the effects of blood sugar surges and drops, and it optimizes satiety.
Castle and King suggest the following combinations:

  • Cookies with milk
  • Candy or chocolate with nut butter on crackers
  • Ice cream with nuts or oatmeal crumble topping
  • Cake with milk or milk alternative

Experts say you can also include your treat as part of a snack or meal. “If you’re at a party, try veggies and hummus and then having some dessert!” King said. “Or eat a small, sensible meal with lean protein, like turkey meat; add some cheese and baby carrots, and then add a fun treat or small sugar-sweetened beverage.”

Don’t eat sugar on an empty stomach. Doing so can lead to a surge in blood sugar, and that itself may alter a child’s behavior, according to Castle.

Make sure that your child is drinking plenty of water. Also, avoid sugar-sweetened beverages on top of eating sugary foods, King advised.

Don’t hype up sugar. If you don’t have sugar and candies in your house often, and you bring sweets home and make a big deal about it, your child may pick up on it and become excited, King explained.

17 Food Combinations that Can Boost Your Health

Hard boiled egg + salad
Out of all the numerous topping options at the salad bar, pick up a hard boiled egg. The fat in the egg yolk helps your body best absorb carotenoids, disease-busting antioxidants found in veggies, according to 2015 research in The American Journal of Clinical Nutrition. Count it as one more reason you should definitely eat the yolks.

Fries + veggies
You don’t want to have to choose between the steamed veggie or fries as a side. Why not get them both? Pairing a nutritious and less-nutritious food choice (officially called a ‘vice-virtue bundle’) can help you stick to your health goals, suggests research in the journal Management Science. One tip to balance the calories—keep your portion of fries/dessert/onion rings small or medium, suggest researchers. If you can order only one size and it’s jumbo, ask for half to be packed upie immediately in a to-go box—or portion out half the plate for a companion. The researchers found that people didn’t actually want to eat enormous piles of treats anyway.

Marinade + steak
Grilling is a quick and healthy way to get dinner on the table, no doubt. However, cooking meat at high temps (a la grilling) creates potentially cancer-causing compounds called heterocyclic amines (HCAs). The delicious solution: marinate your meat. Especially when you use certain herbs and spices in your marinade, including rosemary, it can reduce HCAs by up to 88 percent, according to a study from Kansas State University.

Olive oil + kale
Even though the buzz around heart-healthy fats like olive oil is good, you may still be trying to cut down on oil in an effort to save calories. But it’s time to start sauteeing your veggies again. ‘Vegetables have many fat-soluble vitamins, like A, D, E, and K, which means they need fat to be absorbed,’ explains culinary nutrition expert and healthy living blogger Jessica Fishman Levinson, MS, RDN, of Nutritioulicious. In addition to kale, make sure you cook carrots, sweet potatoes, and broccoli with a little fat too.

Almonds + yogurt
Vitamin D is credited with so many health benefits, including boosting your bones, mood, and immune function. Many yogurts supply one-quarter your daily need for D per cup. To make the most of it though, toss some slivered almonds on top before digging in—especially if you’re eating non- or low-fat yogurt. The fat in the nuts helps raise the levels of D found in your blood 32 percent more compared to having no fat at all, reveals research in the Journal of the Academy of Nutrition and Dietetics.

Sardines + spinach
The fatty fish is abundant in vitamin D, while spinach offers magnesium. In 2013 research, magnesium was shown to interact with the vitamin to boost levels of D in your body. Long-term, this may even help reduce risk of heart disease and colon cancer.

Turmeric + black pepper
You’ve no doubt heard the buzz around the anti-cancer properties of curcumin, the molecule in turmeric that gives the spice its yellow hue. Problem is, it can be difficult for your body to absorb and truly reap the benefits. Combining turmeric with black pepper—which isn’t hard to do in cooking—is a great way to up your body’s ability to use it by 2,000 percent, research shows.

Avocado + toast
If you’re participating in ‘Toast Tuesdays,’ you might have tried the much-obsessed over avocado toast. And it is delicious, FYI. The foods are a perfect match not just for their taste but because the fat from the avocado will slow the rate at which carbs are broken down, absorbed, and converted into sugar, points out Levinson. It’s simple: just spread avocado on whole grain toast and top with some sea salt and pepper (and even lemon juice or hot sauce) and you’re good to go. Add a fried egg for an extra protein boost.

avocado toast

Tomato sauce + spinach
Might as well pack more veggies into the sauce, right? Spinach contains iron, something you may need more of if you’re not eating meat (which is the most abundant source of the mineral). The catch? Iron is not easily absorbed from plant sources, so to tip the scales in your favor, you need to eat these plants with a source of vitamin C, according to Levinson. In this case, tomatoes provide the kick of vitamin C you need to best absorb your spinach. Try her recipe for tomato sauce with spinach, or opt for these other power duos: spinach salad with strawberries, beans and bell peppers, or tofu and broccoli.

Brown rice + lentils
If you’re vegetarian, you may have heard that you should eat certain foods together to ensure you’re getting a complete protein. It’s actually more important that you get a variety of plant proteins throughout the day rather than in one specific meal, says Levinson. Still, some combos are classics for a reason—together, they form a complete protein. Try a brown rice and lentil bowl, beans wrapped in corn tortillas, or nut butter slathered on whole grain bread.

Salmon + leafy greens
Greens to the rescue once more! Vitamin D and calcium are typically found together in dairy, and for good reason: Vitamin D helps your body absorb calcium, both of which are critical for bone health, points out Levinson. But if you don’t eat milk or yogurt, what do you do? Buy  salmon and eat it atop a bed of cooked greens of your choice (sauteeing them cooks them down, making it easier to eat a bigger serving).

Brown rice + garlic + onion
Here’s a reason to make a stir-fry tonight: Garlic and onion help increase the availability of iron and zinc in whole grains, according to Levinson. You can thank the sulfur-containing compounds within the stinky alliums (garlic and onion) for the mineral boost, say researchers.

Carbonation + water
Think we’re getting one by you? If you have trouble getting yourself to drink plain H20, hear us out about why bubbles and water make an ideal match. One German study found that people who made carbonated water at home (think SodaStream), drank more water than those who didn’t—and bonus!—consumed less fat during the day, too.

Red wine + black pepper
The spice does it again. Black pepper contains a compound called piperine, which may help improve the bioavailability of resveratrol (the disease-busting antioxidant in red wine) to tissues, suggests an animal study published in the journal Molecular Nutrition & Food Research. While it doesn’t seem like a natural pairing, simply drink a glass of vino with dinner, and keep the pepper mill handy. Bon appetit!

Green tea + lemon
When you give your cup a squirt of citrus, the vitamin C preserves green tea’s antioxidant catechins, helping them survive the harrowing journey through your digestive tract to where your body can absorb them—so you can reap the benefits from the brew—reveals Purdue University research.

Guacamole + salsa
Pass the chips, please. This is another perfect example of how the antioxidants in certain produce, like tomatoes, need a little fat in order to be absorbed. In fact, a study in the Journal of Nutrition found that eating avocado with salsa improved the absorption of lycopene and beta-carotene in the tomatoes by 4.4 and 2.6 times, respectively. It’s the perfect excuse to go for Mexican tonight.

Pistachios + raisins
When you think about it, trail mix makes lots of sense. Eating dried fruit and nuts together can help improve your metabolic health to help decrease your diabetes risk, suggests a review published in Nutrition Journal. Together, they supply fiber, vitamins, and minerals—and the fat from the nuts helps keep your blood sugar at an even keel. Try making your own custom trail mix instead of paying a premium for the pre-packaged kind.

Kale Is a Surprise on 2019’s ‘Dirty Dozen’ List

While it may still be considered a super food, kale took third place on this year’s “Dirty Dozen” list of fruits and vegetables with the most pesticide residue. Once again, strawberries and spinach took first and second, as they did on last year’s list.

The Environmental Working Group (EWG), a nonprofit organization focused on human health and the environment, has produced the report annually since 2004.

This year, more than 92% of kale samples tested had two or more pesticide residues detected, and a single sample could have up to 18 different residues, EWG found. The most frequently detected pesticide, found on about 60% of the kale samples, was Dacthal, also called DCPA. It has been classified by the Environmental Protection Agency (EPA) as a possible human carcinogen, based on animal studies.

The EWG researchers analyzed test data from the U.S. Department of Agriculture for the report, and kale had not been tested in more than 10 years, says Nneka Leiba, MPH, director of healthy living science at EWG and a co-author of the report. “The percent of [kale] samples with residue increased from 76% to 98%,” she says, citing the difference between the testing in 2007 and in 2017, the data used for this year’s report. “The average number of residues on a single sample increased from two to more than five.”

Leiba stresses that the report should not discourage people from eating fruits and vegetables, although she does suggest people choose organic produce when possible as even washing produce does not remove all pesticides.

Other experts who viewed the report say the amount of pesticides found is not high enough to be a health hazard.

2019’s Dirty Dozen

After adding kale, this year’s list repeats all the entries on last year’s list except for sweet bell peppers, in 12th place last year. This year’s Dirty Dozen:

  1. Strawberries
  2. Spinach
  3. Kale
  4. Nectarines
  5. Apples
  6. Grapes
  7. Peaches
  8. Cherries
  9. Pears
  10. Tomatoes
  11. Celery
  12. Potatoes

Dirty Dozen Plus

The researchers also call out hot peppers, which they say don’t meet their traditional ranking criteria but ”were found to be contaminated with insecticides toxic to the human nervous system.” They found insecticides that are banned on some crops but still allowed for use on hot peppers: acephate, chlorpyrifos, and oxamyl. The EWG recommends buying organic hot peppers or cooking them, as the heat decreases pesticide levels.

Clean 15 List for 2019

The researchers also produce a Clean 15 list — produce least likely to have pesticide residue. Much of this year’s list also repeats last year’s. For 2019, mushrooms made the list, while mangoes dropped off. Overall, more than 70% of the fruit and vegetable samples on the Clean 15 list had no pesticide residues, the researchers found. If they did have residues, only 6% had two or more pesticide types.
  1. Avocados (less than 1% of samples showed detectable levels of pesticides)
  2. Sweet corn (less than 1% of samples showed detectable levels)
  3. Pineapples
  4. Frozen sweet peas
  5. Onions
  6. Papayas
  7. Eggplants
  8. Asparagus
  9. Kiwis
  10. Cabbages
  11. Cauliflower
  12. Cantaloupes
  13. Broccoli
  14. Mushrooms
  15. Honeydew melons

Study Methods, Health Concerns

For the report, researchers ranked pesticide contamination of 47 fruits and vegetables based on an analysis of more than 40,000 samples taken by the USDA and FDA.  The researchers looked at the percent tested with detectable pesticides, the percent with two or more, average number on a single sample, average amount of pesticides found, maximum number found on a single sample, and total found on the crop.
EWG researchers point to the value of a diet low in pesticide residues, citing research such as a recent report finding that people with the highest frequency of organic food consumption had a 25% lower risk of cancers of various types than those who had the lowest intake. Another study found a link between eating foods high in pesticide residues and fertility issues.
A Toxicologist Weighs In
Carl Winter, PhD, a food toxicologist at the University of California Davis, is familiar with the EWG reports. He calls the rankings “arbitrary and of dubious value for consumers.”
When considering the risk of pesticides in food, he says, the actual amount of pesticide detected, the amount of that food eaten by a person, and the toxicity of the pesticide must all be evaluated, and he says the EWG research does not do this.
A Dietitian’s Viewpoint

“As a registered dietitian, the concept of ‘dirty’ and ‘clean’ foods is concerning, unless food is truly dirty,” says Connie Diekman, a registered dietitian and director of university nutrition at Washington University in St. Louis.

She reviewed the report. “The USDA, FDA, and EPA all work to develop guidelines for safe food, setting limits of additives, preservatives, and pesticides at levels that are significantly below levels that might be a concern,” she says. She cautions consumers not to fear certain produce.
The amount of pesticides used is small, she says, ”and the quantity of food we would need to eat for any potential health risk exceeds what people do [eat].”

“If you are more comfortable and can afford to, buy organic, but know it can have organic pesticide residue,” Diekman says.

Growers’ Views
Teresa Thorne is executive director of the Alliance for Food and Farming, an industry group representing farmers who grow both organic and conventional produce. She fears that the report will create ”unfounded and unnecessary fears.” She notes that few Americans eat enough fruits and vegetable daily as is.
The Alliance maintains a pesticide calculator on its companion site, www.safefruitsandveggies.com. According to its calculations, a child could eat 7,446 servings of kale in one day without ill effect, even if it had the highest pesticide residue recorded by the USDA.
EWG Responds

While the levels on individual produce may seem low, ”the overall burden is high,” Leiba says, adding that people are also eating other foods with chemicals and pesticides. “We are talking about a synergistic effect.”

We’re Already Seeing The Health Effects Of Pesticides – Just Not Where You’d Expect

The risk of pesticides to the health of consumers is disputed but there is another group of people already seeing severe impacts.
When you bite into a strawberry or tuck into some spinach or kale you may be congratulating yourself on your healthy food choice. Most people won’t even think about the pesticides they’re likely ingesting.
A list published last week noted that almost all of the samples of strawberries from the most recent tests conducted by the U.S. Department of Agriculture contained residues of at least one pesticide, even after washing. Nearly 60 percent of the sampled kale — frequently championed as a nutritious health food — had pesticide residues.
In all, around 70 percent of produce sold in the U.S. has pesticide residues, according to the annual “Dirty Dozen” report by nonprofit group The Environmental Working Group (EWG), which lists the foods with the highest and lowest levels of pesticide residues. It says we may be exposed to worrying amounts of pesticides.

“Studies have shown that eating fruits and vegetables free of pesticides benefits health, and this is especially important for pregnant women and children,” said Carla Burns, of the EWG.

This is one of a number of recent studies about the pesticides we consume through our fresh food, which are fueling a debate about whether consumers should be worried and how they can reduce exposure.
When it comes to the impact of pesticides on consumer health, the science is far from clear.
Government health experts say we do not need to worry as the levels of pesticide exposure from food are below the levels that could pose a risk to consumers’ health. Carl K. Winter, a food toxicologist at U.C. Davis, specifically analyzed the EWG list in a 2011 study and concluded that the quantities of pesticides mean that risks to consumers were negligible and that moving to organic versions — as the EWG suggests — was unlikely to bring people any measurable health benefits.
Organic produce is farmed to strict federal standards but it is not necessarily pesticide-free — the food just tends to be free from any synthetic pesticides. Also, for many people, buying organic may be prohibitively expensive. A Consumer Reports study found on average organic food was 47 percent more expensive than conventional produce.
The EWG acknowledges that a bigger risk than pesticides, as far as consumers are concerned, is not having enough fruit and vegetables in your diet, full-stop. The same point was echoed by public health researchers.

“It’s not healthy for people to be scared of their food,” said Asa Bradman, a professor at UC Berkeley School of Public Health. “There are a few articles that hint at the benefits of organic versus conventional, but at this point, the information is only limited and the benefits of eating a healthy diet and a good selection of fruit and vegetables means I would not want to discourage consumption of those foods by people.”

As science continues to seek a clearer picture on pesticides and consumer health, one thing that does seem clear is that there’s a swath of people who are much more clearly affected but tend to get ignored: The farmworkers who bring the food to our plates.

“My personal view is that the risk to consumers is low compared to the potential risk to agricultural workers,” said Bradman.

Thousands of farmworkers experience the effects of acute pesticide poisoning including headaches, nausea, shortness of breath or seizures, according to the nonprofit Farmworker Justice. Long-term exposure can lead to chronic health problems, such as infertility, neurological disorders and cancer, says the NGO, which has been documenting pesticide poisoning among workers.
spraying pesticides
One of the starkest examples came from Caldwell in Idaho. A crew of 29 farmworkers began weeding a field of onions and noticed that their clothes were getting wet, but they just assumed it was dew. What they didn’t realize — because no warning signs had been placed on the field — was that a contractor had applied three pesticides to the field during the night without notifying the farm owner.
By lunchtime, some of the workers were vomiting and had headaches and diarrhea. Twenty-two of them were hospitalized, with two in need of critical care. The farm was later fined for its failure to train employees properly and to provide proper safety information on the farm.
These incidents are sadly not uncommon, said Farmworker Justice, yet largely go unreported by national media, which focuses on the more disputed risk of pesticides to consumers.
Not only are farmworkers subjected to these risks, but their families — who live in nearby communities and attend schools neighboring the fields — face similar dangers. Pesticides can be brought into the home on clothing or through the air from neighboring farmland.
The effects are especially worrying in children working with or in close proximity to pesticides, who are particularly vulnerable, according to research. Pesticide exposure has been linked to neurological and behavioral problems in children. A 2010 study, for example, that looked specifically at children living in farming regions of California found a link between pesticide exposure and attention problems.
Farmworkers Justice has called for better and compulsory pesticide training for farmworkers, who are mostly low-income immigrants with limited formal education. It says regulators should ensure Spanish translations of pesticide labels (88 percent of farmworkers are Hispanic), buffer zones around schools and residential areas to protect families being exposed to pesticides through aerial drift, and funding to research the health effects of pesticide exposure.
Virginia Ruiz, from Farmworkers Justice, said little progress has been made on any of these requests. Although there are rules in California for small buffer zones around schools during certain hours of the day, nothing has changed at a national level. There have also been no new funding initiatives to research the health effects of pesticide exposure on people working or living near where they are used, she said.

Alex Chensheng, a professor of environmental exposure at Harvard, blames a strong farming lobby for blocking reform. It is very tough to make any significant policy progress on pesticides, he said, “If we can’t eliminate the conflict of interest, no true progress will be made.”

As well as stricter regulation and better safety measures, there is a safer solution for reducing pesticide risks to both farmworkers and consumers, say campaigners. And that solution is to encourage more farmers to shift away from using pesticides.
There are more than 14,000 certified organic farms in the U.S, according to the most recently available data, with more than 2,500 of them in California. Although organic farms still only make up 1 percent of America’s farmland acres.

“We have nominal programs to support farmers converting to organic and that should be expanded, and we should be prioritizing research on organic farming,” said Kendra Klein, a scientific advisor for environmental organization Friends of the Earth.  She doesn’t suggest all farmers need to convert to organic, but rather that the U.S. should look to move away from a pesticide-intensive system. ″We need to change the system so none of us is exposed,” she said.

The Practice of Letting Go

There are a number of times when our mind clings to something tightly, and it is rarely helpful:

  • I am right, the other person is wrong
  • That person is living their life in the wrong way, they should change
  • My preference is the best way, others are wrong
  • This is the thing I want, I don’t want anything else
  • I really don’t like that, it sucks
  • I should have that person in my life, loving me
  • I shouldn’t be alone, shouldn’t be overweight, shouldn’t be however I am, shouldn’t have this life

In all of these cases, and more, our minds are fixed in a certain viewpoint, and we often judge others. We complain. We are attached to what we want and what we don’t want.

It leads to stress. Unhappiness. Anger. Righteousness. Being judgmental. Distancing ourselves from others. Closed-offedness.

And it leads to being closed off to the beauty of this moment, as it is, full of openness and possibilities.

If you’d like to work on letting go, I would like to offer a simple practice.

mind

 

The Practice of Letting Go

You can actually practice this all day long, because even if we don’t realize it, we’re clinging and hardening and fixing upon viewpoints all day long.

Here’s how to practice:

  1. Start by realizing that you’re hardened. Notice that you are stressed, upset at someone, feeling like you’re right, complaining about someone or a situation, not open to other viewpoints, putting something off, avoiding, tensed. These are good signs that you are holding on, hardened in your viewpoint, fixed, attached, clinging. Get good at noticing this.
  2. Notice the tension in your body. It’s a tightening that happens from your stomach muscles, through your chest, into your throat, up to your forehead. Think of this as your central column, and it tightens up when you think you’re right, or someone else is wrong, or you really want something or don’t want something.
  3. Start to relax those tightened muscles. This is the heart of changing from holding on to letting go. Whatever is tight in your central column, relax. Try it right now. What is tight? Relax that. Soften.
  4. Open your awareness beyond yourself. Once you’ve done this (and you might have to repeat the relaxing, multiple times), you can open your awareness from just your own body and your self-concern, to the world around you. Become aware of the space around you, the people and objects, the light and sound. Open your awareness to the neighborhood around you.
  5. Become aware of openness & possibilities. With your mind opening, you can start to feel more open. Your mind is no longer closed, but has made space for possibilities. You are not fixated on one right way, but are open to everything. This is the beauty of not-knowing.
  6. Open to the beauty that is before you. Now that you are not fixated on rightness or your way or the way things should or shouldn’t be … you can take in the actual moment before you. You’ve emptied your cup, and made room for seeing things as they actually are, and appreciating the beauty of this moment, the beauty of other people, and of yourself.
  7. Step forward with a not-knowing openness. From this place of relaxing your fixed mind, of opening up … take the next step with a stance of not-knowing. You don’t know how things should be, let’s find out! You don’t know if you’re right or wrong, let’s explore! You don’t know the answers, you just hold the questions in your heart, and move into open possibilities.

It’s that simple. And of course, it takes a lot of practice. You can do this at any moment, but it’s helpful to have a short time of day when you set a reminder and then take a few moments to sit still and practice with whatever you’ve been clinging to today.

When we practice like this, we are shifting from our habitual patterns of self-concern and shutting out all possibilities, to openness and not-knowing, to unlimited possibilities and seeing the breath-taking beauty of the world in front of us.

Obstacles That Stop Us from Decluttering
—And How to Overcome Them

Years ago, Cas Aarssen would spend hours looking for lost items, cleaning and tidying, and dusting items she didn’t even like.
Sound familiar?
Sometimes, we get so entrenched in our routines that we don’t see the belongings that no longer belong in our homes. Or we feel too busy, too overwhelmed, too exhausted to tackle a big project such as decluttering. We think it’ll require energy and effort we just don’t have.
Another obstacle to decluttering is actually letting items go. “We are especially reluctant to declutter things that were expensive, have sentimental value, or things that we perceive as being useful ‘someday,’” said Aarssen, an author and professional organizer. “Unfortunately, almost everything can land in one of these categories and by holding onto too many ‘useful’ items, we are making the spaces in our homes ‘useless.’”
We also don’t get rid of items because our stuff starts to represent different possibilities. And that stuff ends up replacing our actual habits. For instance, professional organizer and ADHD coach Debra Michaud, M.A., worked with a client who had a growing yoga DVD collection, which she didn’t use. “What she really wanted was the habit, but she found herself instead buying more and more DVDs.”
Basically, our clutter can personify the people we want to be. The person who lifts weights and runs on the treadmill. The person who always looks put together in fancy (and uncomfortable) shoes. The person who uses cookbooks to make elaborate dinners for their family. The person who does arts and crafts and makes beautiful things.
“Unfinished projects are a very common cause of clutter,” Michaud said. You might be surrounded by broken things you’re planning on fixing one day and piles of magazines you’ll read next week or the week after that or the week after that or….
“People often hang on to [these items] as some sort of albatross, almost a punishment for not getting everything done.”
All of these are super-common obstacles—which you can absolutely overcome. These tips will help.
clutter
Have a clear vision
“The best motivator to declutter is to have a clear vision of what is beyond it,” Michaud said. She suggested asking yourself: What do you really want? What would you really miss?
Remind yourself regularly why you’re decluttering. For instance, clutter robs us of our time and causes a lot of needless stress, said Aarssen, bestselling author of Real Life Organizing and Cluttered Mess to Organized Success. It also zaps our energy, makes us inefficient, and prevents us from living in the present, Michaud said.
Start small
So overwhelm doesn’t stop you from starting, Michaud always suggests tackling clutter in small chunks. Really small. For instance, you might identify one item per day you’re going to donate.
Michaud also recommended using a timer, and starting with five-minute sessions. “Five minutes of focused decision-making is more productive than two hours of wheel-spinning and moving things around.” In fact, she defines clutter as “the interest we pay for deferred decisions (or projects).”
And because of the decision-making required, pick a time when you can focus, Michaud said. “At the end of a tiring workday, for example, will probably yield a frustrating and inefficient organizing session.”
Start with garbage
Aarssen suggested grabbing a garbage bag and filling it as quickly as possible with things you can throw away without any hesitation. For instance, this might include old receipts, expired medications, stale food, empty boxes, and old magazines.
Address your guilt
Michaud always tells her clients “wouldn’t you rather [an item] go to someone who needs it and uses it, than have it sitting in the back of your closet?” She also asks them if the giver would really want them to feel burdened by their gift. And, of course, they wouldn’t.
When it comes to unfinished projects, remind yourself that no one gets to everything. “In a way, letting go of clutter is…coming to terms with the finiteness of life,” Michaud said. However, “ironically, it’s when we let go that we start to feel in control.”
Self-reflect
If your stuff represents different possibilities, wishes and people, consider if those are still true for you. Consider if you even want to do these things, if you’d even enjoy them. Do you want to lift weights and run on the treadmill? Maybe you don’t—and that’s OK. Maybe you love to take walks. Maybe you actually prefer to cook quick meals, and don’t like cooking from recipes.
Either way, you’ll feel so much lighter once you let go of the stuff that represents your unrealized and unwanted dreams—along with those no longer-relevant dreams.
Donate 21 items
“I love this decluttering technique because it is a big enough number that you need to push yourself, but small enough that it isn’t overwhelming and won’t take you more than a few minutes to accomplish,” Aarssen said. Again, the key is to go quickly, and make it into a game.
Create a time capsule
According to Aarssen, when you’re really struggling to relinquish certain items, pack them in a box and write an expiration date on it: “If Not Used By September 2018, DONATE This Box.” Keep your box somewhere in your home. When that date arrives, if you haven’t missed or needed anything in the box, donate its contents, she said.
Get help
“Sometimes the biggest impediment to decluttering is just knowing when to reach out for help,” Michaud said. She suggested hiring a professional organizer or finding a neutral “clutter buddy.” This might be a close friend or a member of Clutterers Anonymous.
Whoever you pick, it’s important that they’re not judgmental and can ask you thoughtful questions, such as: “Do you love it? Do you use it? Realistically will you use it in the next 2 years? Would you buy it again today? Would you miss it?”
Decluttering does take time and energy and effort—but it’s time and energy and effort that aren’t a waste. It’s worthwhile, and it’s absolutely freeing. As Michaud said, “We often don’t even realize how much clutter is weighing on us until it’s gone.”

The Healthiest Water to Drink: Is There Such a Thing?

The science is clear: Staying hydrated and drinking enough water has health benefits.

Hydration can help lubricate and cushion joints, protect sensitive tissues in your body, flush out waste and keep your immune system and even your skin healthy.

Yet when it comes to bottled water, there are several types on the market: spring, purified, mineral, artesian and even alkaline. Is any type best?

It turns out that might come down to personal preference, as more research seems to be needed for a definitive answer.

“For the price, I’m going to get spring water,” said Dr. Eddie Fatakhov, a physician and nutritionist at the Center for Internal and Integrative Medicine in Alpharetta, Georgia. “Because I know it came from the spring.”

Spring, purified, mineral, artesian: What’s the difference?\

Spring water comes from an underground source and must be collected at the spring or through a borehole tapping the spring’s source, according to the International Bottled Water Association.
The association defines purified water as water that has been highly treated – through distillation, deionization or other suitable processes – in order to meet certain standards before being sold.

Mineral water is natural water that has a constant level and relative proportions of mineral and trace elements – containing no less than 250 parts per million total of dissolved solids, according to the water association. No minerals can be added to it.

Then there’s artesian water, which is derived from a well that taps a specific layer of rock or sand.
You also might have seen alkaline water on store shelves; it has a higher pH level than tap water. A pH level is a measure of how acidic or basic water is. Seven is a neutral pH. Higher pH levels are more alkaline, or basic; lower pH levels are more acidic.

“Tap water has a pH of roughly around 7, and alkaline water is closer to about 8 or 9,” Malina Malkani, a registered dietician nutritionist and spokeswoman for the Academy of Nutrition and Dietetics, told CNN in January.

Could alkaline water provide any special health benefits? “There’s really not a lot of evidence either supporting of the health claims that are made about alkaline water or refuting the claims,” Malkani said.

In other words, the jury is still out.

Malkani noted that “if all the body systems are functioning as they should be, the blood pH isn’t going to vary too much. So it’s a misconception that you can, by drinking an alkaline water, drastically affect the pH of the body.”

Illnesses are common causes for changes in the blood pH level. Diabetes can make your blood more acidic, but kidney problems can make it more alkaline. Certain foods, including dairy products, also can make your blood more acidic.

It is more common for companies to manufacture alkaline water, but natural alkaline water can occur when water picks up minerals from areas such as springs, when it passes over rocks in the environment.

“Alkaline compounds are salts and metals that, when added to water, make it more basic,” Malkani said.

All in all, the general consensus among health experts for now is that making sure you are drinking enough water is more important than the type of water you prefer.

The National Academies of Sciences, Engineering, and Medicine recommend that men drink an average of about 3.7 liters (125 ounces) of water each day and that women drink about 2.7 liters (91 ounces). That water can come from beverages and foods, according to the recommendations.

So, for men and women respectively, “that’s 15 cups of water and 11 cups of water, from the eight cups we were taught to believe,” Fatakhov said.

Women who are pregnant or breastfeeding need additional fluids to stay hydrated, according to the Mayo Clinic, which noted that the Office on Women’s Health recommends that women who breastfeed consume about 13 cups of fluids a day.

“North America is dehydrated,” Fatakhov said, and that’s a problem because “83% of your lungs is water. If you take the heart and the brain, 73% is water. If you take the bones, about 31% is water. If you take the kidneys and muscles, about 76% is water. Your body is made up of water.”

‘Water boosts energy’

Water not only benefits your health, it could help you control your weight.

A study published in the Annals of Family Medicine in 2016 found a significant association between not being adequately hydrated and having an elevated body mass index, known as BMI.
BMI is determined based on a person’s height and weight. Having a BMI of 30 or higher is categorized as obese.

The study was based on data from 9,528 people ages 18 to 64, whose levels of hydration were measured in urine samples. Those whose samples showed inadequate hydration tended to have higher BMIs and higher odds of being obese, compared with the hydrated adults.

Water can benefit weight management because staying hydrated helps you better understand when you are actually hungry, and it can boost your metabolism and energy.

“Because of our high water content, it makes sense that our bodies need water to keep our systems functioning. So the next time you hit that afternoon slump, drink a glass of water to increase your energy levels,” Fatakhov said.

“Think about it like this: I tell you to drink water, and you drink water. Your body has to convert that water back to your body temperature. So if you drink cold water, your body has to turn it back to body temperature,” he said. “That’s why they say it’s better to drink cold water than hot water if you’re trying to burn calories.”

If you think you’re not drinking enough water, the US Centers for Disease Control and Prevention offers some tips:
=> Carry a water bottle with you throughout the day for easy access to water.
=> Choose water instead of sugar-sweetened beverages, even when eating out.
=> Add a wedge of lime or lemon to water to help improve taste.
=> Try chilling freezer-safe water bottles for easy access to ice-cold water throughout the day.

Top Ten Reasons to Oppose Water Fluoridation

There are many reasons to oppose water fluoridation, including safety concerns and health risks.

Reason #1 to Oppose Water Fluoridation: Fluoridation is a violation of the individual’s right to informed consent to medication.  Within a community water supply, fluoride is being added to the water of everyone, even if some people do not want it and still others do not even know about the fluoride being added to the water or about its health risks.  Informed consumer consent is needed for water fluoridation, especially because of the alarming lack of safety for this chemical and its health risks.
Reason #2 to Oppose Water Fluoridation: Fluoride is not an essential nutrient. Fluoride is not a required component for human growth and development. In fact, fluoride has been recognized as one of 12 industrial chemicals known to cause developmental neurotoxicity in human beings. Researchers have repeatedly challenged the alleged safety and effectiveness of fluoride.
Reason #3 to Oppose Water Fluoridation: Hundreds of research articles published over the past several decades have demonstrated potential harm to humans from fluoride at various levels of exposure, including levels currently deemed as safe. Fluoride is known to impact the cardiovascular, central nervous, digestive, endocrine, immune, integumentary, renal, respiratory, and skeletal systems, and exposure to fluoride has been linked to Alzheimer’s disease, cancer, diabetes, heart disease, infertility, and many other adverse health outcomes, including fluoride toxicity.
Reason #4 to Oppose Water Fluoridation: People are now exposed to fluoride from an array of sources.  Since water fluoridation began in 1940s, an array of products containing fluoride have been introduced to the average consumer including water, dental products, pesticides, fluoride supplements, other prescription drugs, and many other sources. There is no current accurate estimate of just how much fluoride people are taking in from all of these sources. However, dental fluorosis is recognized as the first visible sign of fluoride toxicity. It is likewise a warning signal of the human health risks associated with fluoride exposure. According to 2010 data from the Centers for Disease Control and Prevention (CDC), 23% of Americans aged 6-49 and 41% of children aged 12-15 exhibit fluorosis to some degree
Reason #5 to Oppose Water Fluoridation: A “one dose fits all” level is unacceptable.  Susceptible populations with low body weights, such as infants and children, and individuals who consume increased amounts of water, such as athletes, military personnel, outdoor laborers, and those with diabetes or kidney dysfunction, can be more intensely effected by fluoride.  Additionally, fluoride is also known to impact each individual differently based on allergies, nutrient deficiencies, genetic factors, and other variables. Notably, a bottle-fed baby in a fluoridated area gets up to 200 times more fluoride than a breast-fed baby, resulting in an increased risk of dental fluorosis and other adverse effects.
Reason #6 to Oppose Water Fluoridation: There is not a wide-spread understanding about how fluoride interacts with other chemicals.  This issue is crucial to understanding risks of artificial water fluoridation, as the multiple chemicals to which we are exposed to can produce distinct reactions and interactions. For example, the fluoride added to many water supplies attracts lead, which can be found in certain plumbing pipes. Likely because of this affinity for lead, fluoride has been linked to higher blood lead levels in children.
Reason #7 to Oppose Water Fluoridation: Does it even work to prevent tooth decay?  The trend of decreased decayed, missing, and filled teeth over the past several decades has occurred both in countries with and without the systemic application of fluoridated water. This suggests that increased access to preventative hygiene services and more awareness of the detrimental effects of sugar are responsible for these improvements in dental health. Research has also documented decreases of tooth decay in communities that have discontinued water fluoridation.  Even proponents of fluoride have suggested that fluoride primarily works to reduce tooth decay topically (i.e. scrubbing it directly onto to teeth with a toothbrush), as opposed to systemically (i.e. drinking or ingesting fluoride through water or other means).
Reason #8 to Oppose Water Fluoridation: Ethical questions have been raised in regard to the use of fluoride, especially because of fluoride’s ties to the phosphate fertilizer and dental industries. Furthermore, researchers have reported difficulties with getting articles published that are critical of fluoride, and an urgent need for an appropriate application of the precautionary principle (i.e. first, do no harm) related to fluoride usage has emerged.
Reason #9 to Oppose Water Fluoridation: Fluoridation discriminates against those with low incomes. Research has indicated that fluoride does not aid in preventing pit and fissure decay (which is the most prevalent form of tooth decay in the U.S.) or in preventing baby bottle tooth decay (which is prevalent in poor communities). Also, research has suggested that in malnourished children and individuals of lower socio-economic status, fluoride can actually increase the risk of dental caries due to calcium depletion and other circumstances. Moreover, people on low incomes are least able to afford avoidance measures (reverse osmosis or bottled water) or medical and dental treatment for dental fluorosis and other fluoride-related ailments.
Reason #10 to Oppose Water Fluoridation: It also poses threats to animals (pets and wildlife), as well as the environment at large.  Animals are exposed to fluoride in the environment through pollution of air, water, soil, and food. It is important to consider their overall fluoride exposure as a result of each of these sources. Harmful effects of fluoride, including species vulnerability, have been reported in an array of wild animals. Even domestic pets have been subjects of reports raising concerns about fluoride exposure, especially through their water and food.

Mushrooms May Reduce Risk of Cognitive Decline in Older Adults

Older adults who consume more than two servings of mushrooms each week may reduce their risk of mild cognitive impairment (MCI) by 50 percent, according to a new 6-year study conducted by researchers from Yong Loo Lin School of Medicine at the National University of Singapore (NUS).

“This correlation is surprising and encouraging. It seems that a commonly available single ingredient could have a dramatic effect on cognitive decline,” said Assistant Professor Lei Feng, who is from the NUS department of psychological medicine, and the lead author of this work.

The study used six types of mushrooms commonly consumed in Singapore: golden, oyster, shiitake and white button mushrooms, as well as dried and canned mushrooms. However, researchers believe it is likely that other mushrooms would also have beneficial effects.

A serving was defined as three quarters of a cup of cooked mushrooms with an average weight of around 150 grams. Two servings would be equivalent to about half a plate. While the portion sizes act as a guideline, the study found that even one small serving of mushrooms a week may still help reduce chances of MCI.

MCI falls between the typical cognitive decline seen in normal aging and the more serious decline of dementia. Older adults with MCI often exhibit some form of memory loss or forgetfulness and may also show declines in other types of cognitive function such as language, attention and visuospatial abilities.

These changes can be subtle, as they do not reflect the disabling cognitive deficits that can impact everyday life activities, which are characteristic of Alzheimer’s and other forms of dementia.
The research, which was conducted from 2011 to 2017, collected data from more than 600 Chinese seniors over the age of 60 living in Singapore. The findings are published online in the Journal of Alzheimer’s Disease.

“People with MCI are still able to carry out their normal daily activities. So, what we had to determine in this study is whether these seniors had poorer performance on standard neuropsychologist tests than other people of the same age and education background,” Feng said.

mushrooms

As such, the researchers conducted extensive interviews which took into account demographic information, medical history, psychological factors, and dietary habits. A nurse measured blood pressure, weight, height, hand grip, and walking speed. The participants also completed a simple screen test on cognition, depression and anxiety.

Finally, a two-hour standard neuropsychological evaluation was performed, along with a dementia rating. The overall results of these tests were discussed in depth with psychiatrists to come to a diagnostic consensus.

The researchers believe the reason for the reduced prevalence of MCI in mushroom eaters may come down to a specific compound found in almost all varieties. “We’re very interested in a compound called ergothioneine (ET),” said Dr. Irwin Cheah, Senior Research Fellow at the NUS Department of Biochemistry.

“ET is a unique antioxidant and anti-inflammatory which humans are unable to synthesize on their own. But it can be obtained from dietary sources, one of the main ones being mushrooms.”

A previous study by the team on elderly Singaporeans revealed that plasma levels of ET in participants with MCI were significantly lower than age-matched healthy individuals. The findings led to the belief that an ET deficiency may be a risk factor for neurodegeneration, and increasing ET intake through mushroom consumption might possibly promote cognitive health.

The next step is to conduct a randomized controlled trial with the pure compound of ET and other plant-based ingredients, such as L-theanine and catechins from tea leaves, to determine the potential of such phytonutrients in delaying cognitive decline.

Everything You Need to Know About Potassium

Potassium is one of the seven essential macrominerals. The human body requires at least 100 milligrams of potassium daily to support key processes.

A high potassium intake reduces the risk of overall mortality by 20 percent. It also decreases the risk of stroke, lowers blood pressure, protects against loss of muscle mass, preserves bone mineral density, and reduces the formation of kidney stones.

The primary functions of potassium in the body include regulating fluid balance and controlling the electrical activity of the heart and other muscles.

This MNT Knowledge Center article provides an in-depth look at recommended intake of potassium, its possible health benefits, reliable sources of potassium, the effects of consuming too much or too little potassium, and any potential health risks of consuming potassium.

Fast facts on potassium

  • Adults should be consuming 4,700 milligrams (mg) of potassium a day. However, fewer than two percent of people in the U.S. consume enough potassium.
  • Potassium supports blood pressure, cardiovascular health, bone strength, and muscle strength.
  • Beet greens, white beans, soy beans, and lima beans are the foods highest in potassium.
  • Potassium deficiency can lead to fatigue, weakness, and constipation. It can escalate to paralysis, respiratory failure, and painful gut obstructions.
  • Hyperkalemia means that there is too much potassium in the blood, and this can also impact health.
  • Potassium is available in supplements, but dietary sources are most healthful.

Recommended intake

Potassium is a crucial nutrient, and a very small percent of people in the U.S. consume enough.
The Adequate Intake recommendation for potassium is 4,700 milligrams (mg) per day for adults. Most adults do not meet this recommendation.

The National Health and Nutrition Examination Survey (NHANES) also reported that less than two percent of people in the U.S. meet the daily 4,700-mg potassium requirement. Women consume less potassium than men on average.

The World Health Organization (WHO) recommend an intake of 3,510 mg per day and agree that most of the global population is not meeting this recommendation.

Potassium supplements are available. However, it is best to obtain any vitamin or mineral through food. It is not individual vitamins or minerals that make certain foods important for healthful living, but the combined efforts of a range of nutrients.

Benefits

Potassium carries proven health benefits.

It is an electrolyte that counteracts the effects of sodium, helping to maintain consistent blood pressure. Potassium is also important for maintaining the balance of acids and bases in the body. Bases are alkalis that have not yet dissolved in water.

Blood pressure and cardiovascular health

Low potassium intake has repeatedly been linked with high blood pressure and cardiovascular disease. Maintaining a low sodium intake is essential to lowering blood pressure, but ensuring a good intake of potassium may be just as important.

An increase in potassium intake along with a decrease in sodium is crucial to reducing the risk of cardiovascular disease.

In one study, those who consumed 4,069 mg of potassium per day had a 49 percent lower risk of death from ischemic heart disease compared with those who consumed about 1,000 mg per day.

Bone and muscle maintenance

Potassium-rich foods maintain an alkaline environment in the body, unlike in acidosis. Metabolic acidosis is triggered by a diet full of acidifying foods like meat, dairy products, and processed cereal grains. Acidosis is a common outcome of the typically acidic Western diet.

Acidosis can cause nitrogen excretion, loss in bone mineral density, and muscle wasting. A diet high in potassium can help preserve muscle mass in older people, as well as during conditions that tend to lead to muscle wasting, such as diabetic ketosis. However, a sufficient potassium intake can help prevent this.

One study found that participants that took in 5,266 milligrams of potassium per day maintained an average of 3.6 more pounds of lean tissue mass than those with a potassium intake 50 percent lower. Some studies also show an increase in bone density with high potassium intake.

Foods high in potassium

White beans are among the most potassium-rich foods, as are many other types of bean.
Potassium is found in many whole, unprocessed foods.

Some of the best sources of potassium are fresh leafy greens, avocados, tomatoes, potatoes, and beans. Processing greatly reduces the amount of dietary potassium. A diet high in processed foods is probably low in potassium.

Many processed foods are also high in sodium. As sodium consumption rises, increased potassium is needed to cancel out the effect of sodium on blood pressure.

Here is a table showing the nutritional benefit provided by one cup of the most potassium-rich foods.

Food type (1 cup)                     Amount of potassium provided in milligrams (mg)
Cooked, boiled, or drained beet greens, without salt 1,309
Canned white beans 1,189
Cooked, boiled, or drained soy beans, without salt 970
Cooked, boiled, or drained lima beans, without salt 969
Baked sweet potato 950
Sliced avocado 708
Cooked, boiled, or drained mushrooms, without salt 555
Sliced banana 537
Red, ripe, raw tomatoes 427
Raw cantaloupe melon 417

A good way to reduce the harmful effects of high-sodium meals is to eat a high-potassium fruit or vegetable with each meal.

There are many more sources of potassium outside of this list. Be sure to check the potassium content of any preferred foods using the United States Department of Agriculture (USDA) National Nutrient Database.

Deficiency

Potassium deficiency can cause a range of symptoms and health problems. It is also known as hypokalemia.

A normal potassium level is defined as between 3.5 and 5.0 millimoles per liter (mmol/L).

Hypokalemia is diagnosed when potassium levels fall below 3.5 mmol/L. Mild potassium deficiency will generally not present with symptoms. A potassium level lower than 2.5 mmol/L is considered extremely deficient, and symptoms will become more severe as levels reduce.

Symptoms of low potassium levels include:

  • malaise and fatigue
  • weakness and muscle pain all over the body
  • constipation

Extremely low potassium levels can cause:

  • severe muscle weakness and paralysis
  • respiratory failure
  • painful obstructions in the gut
  • tingling, crawling, numb, or itchy sensations main felt in the hands, feet, legs, or arms
  • intermittent muscle spasms

Low potassium can be diagnosed using simple blood tests and treated by alterations to the diet, including supplements. Having regular medicals and health screenings will also help a person track their potassium levels and avoid any potential shortfalls.

Risks

Potassium can also cause health problems when a person consumes more than the 4,700 mg recommended Adequate Intake.

Individuals with good kidney function can efficiently rid the body of excess amounts of potassium in the urine. This process normally has no adverse side effects.

There have been a small number of reports that potassium toxicity is associated with an extremely high intake of potassium supplements. No food-related potassium toxicity has ever been reported.

Hyperkalemia

Consuming too much potassium can be harmful to people whose kidneys are not fully functional. Excessive potassium consumption can lead to hyperkalemia, in which the kidneys cannot remove enough potassium from the body. This can be dangerous if the condition escalates quickly.

Potassium levels between 5.1 and 6.0 mmol/L are considered high and warrant monitoring and management. Levels higher than 6.0 mmol/L are dangerous.

Hyperkalemia will mostly be either symptomless or present very few symptoms. However, when symptoms do present, they are similar to those that occur in hypokalemia.

Severe or sudden hyperkalemia can cause heart palpitations, shortness of breath, and chest pain. At this stage, hyperkalemia can become a life-threatening condition that requires immediate medical attention.

Reducing potassium intake

Hyperkalemia is treated by reducing the intake of potassium.

Potassium and sodium are part of a constant balancing act within the body. Maintaining this balance is vital to the smooth function of bodily systems.

If hyperkalemia is suspected, it is best to avoid high-potassium foods, such as the ones listed above. Salt substitutes, herbal remedies, or supplements should also not be consumed. These can all boost potassium levels rather than balance them.

High potassium levels have been linked to two cases of cardiac arrest. If the kidneys are unable to remove excess potassium from the blood, the effects of potassium on the heart could be fatal.

Takeaway

Potassium is vital to bodily function but does not hold the answers to healthful living on its own. Overall eating patterns and dietary balance are most important in bolstering health and keeping disease at bay.

10 Foods Higher in Potassium Than a Banana

Surprise! Bananas deliver less than 10 percent of our daily dose of the mineral potassium, which protects against stroke and heart disease. Here’s how to get the rest.

Butternut squash

This sweet root vegetable tops bananas in the rankings of foods high in potassium, delivering 582 milligrams of the essential mineral in one cup, compared to 420 milligrams in a banana. According to the U.S. RDA, adults should aim to get 4,700 milligrams of potassium a day.

Edamame

Soybeans are one of the top foods with potassium, packing in 676 mg per cup. Edamame beans are also one of the world’s best sources of plant-based protein because they contain all the essential micronutrients our bodies need to build muscle. Edamame are delicious roasted with a sprinkle of salt.

White and sweet potatoes

Fresh organic potato stand out among many large background potatoes in the market. Close-up potatoes texture.

A sweet potato contains 438 mg of potassium, while its cousin, the white potato, delivers a whopping 950 mg. Both types of tubers also come with high levels of vitamin A. People often confuse yams and sweet potatoes; for potassium, you’ll want to stick with sweet potatoes.

Swiss chard

Get 961 mg of potassium by cooking up a single cup of Swiss chard. Not only is it one of the foods high in potassium, but the leafy green is also packed with iron, calcium, and vitamins A, C, and K. Foods with potassium aren’t the only ones you should be adding to your diet.

Beet greens

Another one of the foods high in potassium? Chop and roast just one cup of beet greens for a 655-mg dose. As a bonus, you’ll also get folate, manganese, and copper, not to mention dietary fiber, magnesium, phosphorus, vitamin C, iron, and vitamin B6.

Tomato sauce

Not many people think of tomato sauce as one of the foods high in potassium, but topping your pizza, pasta, or vegetables with one cup of the stuff will get you 905 mg of the nutrient. Make sure to pick the perfect pasta shape to go with your tomato sauce.

Black beans

When you’re looking for foods high in potassium, black beans are a top choice, delivering a hefty 681 mg. This legume is also a great source of vegetarian protein and dietary fiber, plus a long list of other health boosters, including antioxidants, iron, phosphorous, calcium, magnesium, manganese, copper, and zinc.

White beans

Surprisingly, white beans are the best source of potassium you can get. Just one cup contains an impressive 1,190 mg of potassium, which is about one-fourth of the daily recommended amount. Similar to black beans, they also contain protein, fiber, and a host of other healthful vitamins and minerals.

Watermelon

Two slices of watermelon contain a whopping 640 mg of potassium. Plus, its star ingredient is lycopene, a plant pigment that has been known to reduce the risk of some cancers.

Yogurt

Yogurt is a great source of calcium and delivers 380 mg of potassium per eight-ounce cup. Bring it over the banana threshold by adding one ounce of hazelnuts, which have 211 mg of potassium.
