Blueberries May Help Reduce Your Risk Of Alzheimer’s Disease: It’s All About The Anthocyanins

Blueberries deliver the most delicious wallop of vitamin C found on the planet (in my humble opinion). One serving supplies 25 percent of your daily C requirement plus additional heart-healthy fiber and manganese, important to bone health. A super-achiever when it comes to antioxidant strength, this fruit may also lower your risk of heart disease, cancer, and, new research suggests, even Alzheimer’s disease.

A team of University of Cincinnati scientists led by Dr. Robert Krikorian says the healthful antioxidants within blueberries provide a real benefit in improving memory and cognitive function in some older adults. Based on their work, they believe adding blueberries to your diet may help you prevent neurocognitive decline.

Blueberries acquire their deep color from anthocyanins, a type of flavonoid that acts as an antioxidant within the fruit, explains the U.S. Highbush Blueberry Council. Generally, antioxidants help to prevent age-related damage at the cellular level within the plants. While some scientists believe consuming foods rich in antioxidants will help delay aging, not all scientists, including those at the National Institutes of Health, entirely support that theory.

Still, eating a diet rich in fruits and veggies is unquestionably good for your health with many scientists analyzing and testing specific foods to understand whether they might prevent a particular illness. Quite a few studies, Krikorian and his colleagues note, have found blueberries beneficial in preventing dementia.

Silver Tide
One type of dementia, Alzheimer’s disease, causes problems with memory, thinking, and behavior. This neurodegenerative disorder develops in a healthy brain, its symptoms appearing slowly and then worsening over time. Eventually, this disease becomes severe enough to interfere with daily tasks and in the end disrupts even the autonomic nervous system, which controls heart rate and breathing. If they live long enough, Alzheimer’s patients die because their breathing stops. Currently 5.3 million Americans suffer from Alzheimer’s disease, yet as the nation’s population grows older, that number will almost inevitably rise. The Alzheimer’s Association calculates that the number of Americans with this disorder will reach more than seven million by 2025.

How can science slow this trend?

Following up on earlier clinical trials showing blueberries boost cognitive performance, Krikorian and colleagues conducted two new studies. The first involved 47 adults, 68 years old or older and beginning to show signs of mild cognitive impairment — a risk factor for Alzheimer’s. First, the researchers conducted tests and a brain scan for each participant. Then, after forming two groups, one group of participants ate a placebo powder once a day for 16 weeks, while the other consumed a freeze-dried blueberry powder (equivalent to a single cup of berries).

Conducting the same tests and comparing the groups, Krikorian and his colleagues observed comparative improvement in cognitive performance and brain function among the adults who ate blueberry powder.

“The blueberry group demonstrated improved memory and improved access to words and concepts,” said Krikorian in a statement to the press. Additionally, a second scan showed increased activity in the brains of those in the blueberry group.

The team’s second study included 94 people between the ages of 62 and 80, all confessing to some memory problems. The researchers believed these participants to be in better cognitive “shape” than the first group, however no objective measurements verified this. For this study, the researchers divided the participants into four groups. Each group received either blueberry powder, fish oil, fish oil and powder, or placebo.

A hoped-for replication of the first study did not occur. Cognition proved somewhat better for those taking either blueberry powder or fish oil separately, yet memory barely improved, certainly not as much as in the first study, Krikorian noted. Even the scans showed similar lukewarm results. The team believes participants’ less severe cognitive impairments contributed to this weakened effect.

Blueberries may not show measurable benefit for those with minor memory issues or who have not yet developed cognitive problems, the combined results of the two studies suggest. Perhaps blueberries effectively treat only those patients who already show signs of mental impairment.

Nevertheless, Krikorian says, the very same ingredient that bestows color may provide blueberries with their brain benefits; in past animal studies, scientists have shown anthocyanins improve cognition.

Easy Tricks To Teach Kids How To Deal With Stress Through Mindfulness

But experts say if you want to teach your children to be mindful, you have to be mindful, too.

The back-to-school season brings its own unique stressors to just about everyone: young children starting school for the first time, older kids dealing with longer days and social pressures, teenagers who have to make decisions about their futures, and of course to parents who might also feel overwhelmed. But researchers at Vancouver’s Kelty Mental Health Resource Centre have suggested strategies to deal with back-to-school stress.

“Mindfulness” has become a bit of a buzzword recently, along the lines of “radical wellness” and “living your best life.” But beyond the context of GOOP, there’s a lot of value in the idea that we could all focus more on the present moment.

The basic tenet of mindfulness is the idea that stress and pain is often the result of thinking about past regrets or worrying about the future, and that can be combated by coming up with strategies that focus on remaining in the present moment. HuffPost Canada spoke to Dr. Dzung Vo, an adolescent medicine specialist and pediatrician at British Columbia’s Children’s Hospital, about how kids can implement those strategies.

“I define mindfulness as paying attention in a particular way, on purpose, in the present moment, and with unconditional love,” Dr. Vo says. “It’s not meant to be something that you succeed or fail at, it’s more of an intention and an attitude that we orient ourselves to when we practice being in the present moment.”

Studies have shown that mindfulness can reduces stress and anxiety, improve attention and memory, and encourage empathy and monitor your emotions. It’s also been shown to be beneficial physically by lowering blood pressure and heart rate. And new research is currently underway to determine whether it can be a helpful tool to fight against depression.

Vo’s pediatric practice focuses primarily on teenagers, but he says there are effective strategies that can help just about every age group understand their feelings, process their reactions, and live a healthier emotional life.

Babies and toddlers
By far the most important factor in teaching very young children to be mindful is to have a parent or caregiver who is mindful themselves.

“What we know from neuroscience is that the parent’s own mental and neurologic state has a profound influence on regulating the child,” Vo told HuffPost Canada. “If the parent or caregiver can be mindful, present, attentive, and attuned with unconditional love and presence, then that will affect the child in very deep and healthy ways.”

One of the principles of mindfulness is approaching a subject with “beginner’s mind” — a sense of curiosity and presence you might use if you were trying something for the first time. This is something young children generally do anyways. “Kids are actually pretty naturally in the moment, so it’s not too hard to do,” Vo says.

Studies have shown that mindfulness can reduces stress and anxiety

School-age kids
Vo suggests adding brief mindfulness exercises into the routine of slightly older children, maybe at bedtime or when they get home from school. One idea is to get them to lie with a teddy bear on top of their belly and ask them to slowly breathe in and out, he says. Watching the teddy bear go up and down with their breath will put them in tune with their bodies, and put them in a state of calm.

Another useful activity can be to sing songs with lyrics that remind kids to think about where they are and how they feel — he suggests “Planting Seeds” by Zen master Thich Nhat Hanh. “As kids go through their day, when they need a mindful moment, they just sing the song,” he says. “Singing it actually is a practice, because it cultivates that mindful attitude.”

Crafts and artwork, approached with the “beginner’s mind,” are another helpful way to practice mindfulness. Vo suggests gently guiding children to be curious and really focus on their surroundings and what they might be engaging in.

“Maybe they’re drawing a flower in front of them,” he says. “Encourage the child to really pay attention to it by asking them: What are you seeing there? What are you noticing? What are the colours? What are the shapes?”

It isn’t particularly important that children understand the idea of mindfulness, he says.

“It’s more important to have experiences than to talk too much about the concepts.” And again, he stresses that the most important way to teach mindfulness to kids is the mindful presence of the parent or caregiver.

Teenagers
In his sessions with teens, Vo will often get them to try out their “beginner’s mind” by slowly eating one single raisin. “That might seem very simple and boring, but when you bring curious attention to it, you find experiences that seem tedious or boring may be quite interesting, or quite relaxing, or quite enjoyable in ways that we hadn’t considered when we go through them in autopilot mode.”

Many teenagers will bring what Vo calls “informal meditation” to a wide variety of day-to-day activities: breathing deeply and considering their senses while walking the dog, or waiting for the bus, or washing dishes. It can particularly help before a stressful situation at school — right before writing an exam, for instance.

There isn’t a lot of research on the benefits of mindfulness for teens, but Vo says that he believes that’s the time of life when those practices would be most beneficial.

Studies of adults have demonstrated that mindful practices can actually change the parts of the brain linked to memory, self-image, and emotional regulation. Because adolescent brains are changing quickly and profoundly, Vo says he thinks the effects would be even more significant. One of the biggest adolescent brain changes involves the prefrontal cortex, the part of the brain responsible for emotional regulation and executive functioning, which develops throughout the teenage years up until the early 20s. It develops through focused attention and concentration, he says, which suggests that the more that they use these neurologic pathways to help regulate their brains, the stronger those connections will get.

Massive Study Yields Exciting Findings about Gut Health and the Microbiome

Gut health could be the biggest trend in the health field right now. Everywhere I turn people are discussing the importance of their gut health and how it is linked to their overall health, as well as the benefits of probiotics. And, for good reason: a growing body of research shows that what happens in our gut expands well beyond the gut.

Now new research shows that the health of your gut is significantly influenced by what you eat. A new study assessed 15096 fecal samples provided by 11336 people, published in the journal of the American Society for Microbiology, found some exciting facts about gut health and the microbiome, which is the total of all the microbes in a living being.

We each have a microbiome and no two microbiomes are alike, although there can be some similarities between them. The microbiome is a sort of microbial fingerprint. And, thanks to the new research, we have greater insight into the effect of diet on our microbiome. Here are some of the findings from this exciting study:

1) Plant-based diets produce the most diverse microbiomes. Diverse microbiomes seem to confer health benefits. Consider people who struggle to lose weight: earlier research in the journal Beneficial Microbes shows that they tend to have less diverse strains of beneficial bacteria and a lower ratio of beneficial microbes to harmful ones.

2) Eating more than 30 types of plant foods weekly yields the most diverse microbiome. In other words, it’s important to eat a plant-based diet but also one that has tremendous diversity. So, expand your horizons when it comes to trying new vegetables, fruits, nuts, seeds and grains. Your microbiome will thank you. And, who knows? You might even discover a new favorite food.

3) There is a lower incidence of bacterial resistance in those who eat the greatest variety of plant foods weekly. This is great news since more and more varieties of harmful bacteria like E. coli and MRSA are, not only becoming more prevalent, they are also becoming resistant to the typical drug treatment: antibiotics. This is an astounding discovery on its own. We tend to assume that all of a certain variety of bacteria have the same level of potency against humans, but the research shows that people who eat a large variety of plant-based foods are less likely to be host to these disease-causing, resistant bacteria. People who ate more than 30 types of plant foods weekly had less resistance to antibiotics.

4) The gut bacteria of people suffering from mental health issues, including: post-traumatic stress disorder (PTSD), schizophrenia, depression or bipolar disorder were more similar to others suffering from mental disorders than to those who do not suffer from mental disorders. While the scientists conducting the study did not draw any conclusions, there may be a possible connection between gut health and mental health. Certainly other research suggests that is indeed the case. Research in the Journal of Physiological Anthropology found a link between gut bacteria and increased activity in brain pathways that improve brain health and reduce depression risk.

How can you reap the benefits of this exciting research?

There are endless ways to boost the variety of plant-based foods you consume, but the following ones should help you get started:

  1.    Start by replacing meat in your diet with plant-based options. Start with Meatless Mondays but don’t hesitate to go meatless the rest of the week as well
  2.    The next time you pass by that odd-looking fruit or vegetable in the produce section of your grocery store, add it to your cart. It’s easy enough to find recipes for lesser-known foods using a quick Internet search. And, most importantly, add the food to your diet.
  3.    Instead of just snacking on almonds or another nut, branch out to try Brazil nuts, cashews, hazelnuts, pecans, pistachios, etc. Choose raw, unsalted varieties.
  4.    Rather than just add a can of kidney beans to your soup, stew, or chili, opt for bean varieties you are less familiar with. That could include: chickpeas, lentils, pinto beans, Romano beans, black beans, navy beans, etc.
  5.    The next time a snack attack strikes, choose a piece of fruit or a bowl of mixed berries.
  6.    When you have a craving for salty foods, choose traditionally-fermented pickles, pickled green beans, pickled beets or other foods with live cultures. Not only will you be getting a wider variety and a greater quantity of plant-based foods, you’ll also help expand the beneficial microbes you consume. Be sure to choose pickled foods that state “live cultures” or “unpasteurized” on the label.

Connecting the Dots Between Physical and Emotional Health

There’s a link between your emotional health and your physical well-being, so take time to nurture both.

To be completely healthy, you should take care not only of your physical health, but your emotional health, too. If one is neglected, the other will suffer.

What’s the Connection Between Emotional and Physical Health?

There’s a physical connection between what the mind is thinking and those parts of the brain that control bodily functions. According to Charles Goodstein, MD, a clinical professor of psychiatry at New York University’s Langone School of Medicine in New York City, the brain is intimately connected to our endocrine system, which secretes hormones that can have a powerful influence on your emotional health. “Thoughts and feelings as they are generated within the mind [can influence] the outpouring of hormones from the endocrine system, which in effect control much of what goes on within the body,” says Dr. Goodstein.

“As a matter of fact, it’s very probable that many patients who go to their physician’s office with physical complaints have underlying depression,” he says. People who visit their doctors reporting symptoms of headache, lethargy, weakness, or vague abdominal symptoms often end up being diagnosed with depression, even though they do not report feelings of depression to their doctors, says Goodstein.

While unhappy or stressed-out thoughts may not directly cause poor physical health, they may be a contributing factor and may explain why one person is suffering physically while someone else is not, Goodstein adds.

How Exactly Does the Mind Affect the Body?

There are many ways in which the mind has a significant impact on the body. Here are a few:

  • Chronic illness and depression Depression has been shown to increase the risk for chronic illnesses, such as heart disease, stroke, cancer, and diabetes, according to an article published in 2013 in the Primary Care Companion for CNS Disorders. A review of studies on diabetes and depression, published in August 2015 in the Canadian Journal of Diabetes, found that depression put people at a 41 percent higher risk for the condition. Researchers aren’t yet clear on how mental health influences physical health, but according to a study published in September 2017 in the journal Psychiatria Danubina, it may be that depression affects the immune system, and that habits associated with depression, such as poor diet or lack of physical activity, may create conditions for illness to occur.
  • Depression and longevity According to a review published in June 2014 in World Psychiatry, many major mental illnesses are associated with higher rates of death. Another study, published in October 2017 in the Canadian Medical Association Journal, suggests that those with depression may have life spans from about 7 to 18 years shorter than the general population.
  • Physical symptoms of emotional health distress People who are clinically depressed often have physical symptoms, such as constipation, lack of appetite, insomnia, or lethargy, among others.
  • White-coat syndrome This is a condition in which a person’s blood pressure increases the minute they step into a doctor’s office. In white-coat syndrome, anxiety is directly related to physical function — blood pressure. “If you extrapolate from that, you can say, what other kinds of anxieties are these people having that are producing jumps in blood pressure? What is the consequence of repeated stress?” asks Goodstein.

And on the other hand: “Those individuals who have achieved a level of mental health where they can manage better the inevitable conflicts of human life are more likely to prevail in certain kinds of physical illness,” says Goodstein.

How Should You Care for Your Emotional and Physical Well-Being?

It’s hard to do, but slowing down and simplifying routines can go a long way to strengthening your mental and physical health.

  • Eat right. A healthy, regular diet is good for the body and mind.
  • Go to bed on time. Losing sleep is hard on your heart, may increase weight, and definitely cranks up the crankiness meter.
  • If you fall down, get back up. Resilience in the face of adversity is a gift that will keep on giving both mentally and physically.
  • Go out and play. Strike a balance between work and play. Yes, work is a good thing: It pays the bills. However, taking time out for relaxation and socializing is good for your emotional health and your physical health.
  • Exercise. A study published in October 2017 in Reviews in the Neurosciences shows that exercise improves your mood and has comprehensive benefits for your physical health.
  • See the right doctor, regularly. Going to the right doctor can make all the difference in your overall health, especially if you have a complicated condition that requires a specialist. But if your emotions are suffering, be open to seeing a mental health professional, too.

Total health depends on a healthy mind and body. Take time to nurture both.

The Neuroscience of Bad Habits and Why It’s Not About Will Power

Why are bad habits so hard to break? What if the bumper sticker “Just Say No!” actually works against us? If willpower were the answer to breaking bad habits then we  decisionswouldn’t have drug addiction or obesity. There’s something going on in our brains where we literally lose the ability for self-control, but all hope isn’t lost.

Nora Volkow, head of the National Institute on Drug Abuse calls the phrase “Just Say No!” “magical thinking.”

It appears that dopamine is one of the main chemicals regulating the pleasure center of the brain. At the most basic level, it regulates motivation — it sends signals to receptors in the brain saying, “This feels good!”

Whether you’re a heroin addict and you see an association to heroin, you’re a caffeine addict and you see a cup of coffee, you’re a Smartphone addict and you see another person pick up their phone, or if you’re hungry and you see some good-looking food, your brain rushes with dopamine and that is now caught on brain-scanning machines.

The fascinating thing is that Volkow has found that  the images alone affect the rise of dopamine in our brains. So if we pass a McDonald’s and see the arches, our brain associates that with a tasty hamburger (for some) and shoots up dopamine. That good feeling will unconsciously drive the motivation to go in and get a Big Mac. It’s a conditioned response. The same goes for anything including most likely our relationships to our phones.

A blue button with the word Change on it

What can we do?

It makes sense why more and more addiction centers are integrating mindfulness into their curriculum. Mindfulness practice has been shown to activate the prefrontal cortex and cool down the amygdala. This gives us the ability to widen the space between stimulus and response where choice lies and access possibilities and opportunities we didn’t know were there before. This is crucial when it comes to our addictive behaviors to take a step back, “think through the drink” and recognize the various options that lie before us.

We can learn to step into the pause, notice the sensation of the urge that’s there and as the late Alan Marlatt, Ph.D. said, “surf the urge” as it peaks, crests and falls back down like a wave in the ocean.

One place to start is to just get curious about the pull you feel to whatever you think you’re compulsive with. An easy one besides some of the arguably more destructive habits (drugs, alcohol) is our phones.

Today, be on the lookout for what cues you to check your app. Do you see someone else doing it? Are you waiting somewhere and there’s something uncomfortable about waiting? Is it a certain time of day or place?

Training your brain to recognize this cue can help you get some space from it to ask, “What do I really want to pay attention to right now? What matters?” As we get better at recognizing that space between stimulus and response and making the choices that run alongside our values, like riding a bike, it will start to come more naturally.

Just because our brains have been altered by our compulsive behaviors, doesn’t mean we’re destined to fall into the same habits. With the right skills, community and support we can learn how to break out of routine and into a life worth living.

The Food Flavouring That Causes Dementia

90% use too much of a flavouring that can cause inflammation of blood vessels in the brain.

A high-salt diet is linked to dementia, new research finds.

Salt causes the delicate lining of the brain’s blood vessels to inflame, because of signals sent from the gut.

Fully 90% of Americans consume above the recommended dietary maximum of 2,300 mg per day.

Dr Costantino Iadecola, study co-author, said:

“We discovered that mice fed a high-salt diet developed dementia even when blood pressure did not rise.
This was surprising since, in humans, the deleterious effects of salt on cognition were attributed to hypertension.”

The effect was quickly reversed by lowering salt intake.

The conclusions come from a study in which mice were fed a high-salt diet that is equivalent to a high-salt diet in humans.

Subsequently, the mice had much worse cognitive function.

Their brains showed 28% less activity in the cortex and 25% less in the hippocampus.

They had problems getting around a maze and did not show the usual interest in new objects placed in their cage.

They also had poorer blood flow in their brains and the integrity of the blood vessels there was worse.

However, these changes were reversed once the mice were returned to a normal diet.

The scientists found that these changes had nothing to do with higher blood pressure.

Worse cognitive functioning in the mice was seen even when the mice had normal blood pressure.

They were the result of signals sent from the gut to the brain.

These activated an immune response in the brain which increased levels of interleukin-17.

This eventually resulted in the inflammation of the delicate lining of the brain’s blood vessels.

The study was published in the journal Nature Neuroscience (Faraco et al., 2018).

This Food May Help You Sleep Better

Forget warm milk. A new study from the University of Pennsylvania says that fish may be the key to a good night’s sleep.

The paper, published Thursday in Scientific Reports, found an association between regular fish consumption and high sleep quality among Chinese schoolchildren, likely thanks to the omega-3 fatty acids found in fish. Largely as a result of that improved sleep, the researchers found, the children also scored higher on IQ tests.

“There’s a relationship between fish consumption and higher cognitive functioning. What what we document here is that it’s the better sleep that explains the relationship,” says Adrian Raine, one of the paper’s authors and a professor of criminology, psychiatry and psychology at Penn. “From A to B to C: From fish consumption to better sleep to higher cognitive functioning.”

The researchers asked 541 schoolchildren in China between ages 9 and 11 to describe their eating habits, including how often they ate fish. Their parents, meanwhile, were asked to answer questions about the kids’ sleep patterns. Researchers then administered IQ tests when the children turned 12.

They found links between eating fish regularly — the more, the better — and both improved sleep and higher IQ scores. But, Raine explains, it appears that many of the cognitive benefits can be traced back to bedtime. “The brain is so much more plastic early on in child development,” he says. “We might anticipate that fish consumption earlier in life may be particularly beneficial for a child’s sleep and cognitive functioning.”

While the study focused on kids, Raine says “it’s quite reasonable to imagine that these findings can also apply to adults,” citing studies that have shown that omega-3 fatty acids can alter psychological functioning in adults.

Eating fish just a few times a month may improve your brain functioning, Raine says. (Fish and omega-3s have also been shown to be good for your heart.)

“The important thing is really having a balanced diet. It needn’t be a lot,” Raine says. “Even if parents could just get fish on the table once a week, that could be enough to make a bit of a difference over at school and in long-term performance, and especially sleep.”
