The World’s Most Nutritious Foods

After analysing more than 1,000 raw foods, researchers ranked the ingredients that provide the best balance of your daily nutritional requirements – and they found a few surprises.

Many of us are paying more attention to our diets and how the food we eat can support our health. To help sort out the fact from the fiction, BBC Future is updating some of our most popular nutrition stories from our archive.

Imagine the ideal food. One that contains all the nutrients necessary to meet, but not exceed, our daily nutrient demands. If such a food existed, consuming it, without eating any other, would provide the optimal nutritional balance for our body.

Such a food does not exist. But we can do the next best thing.

The key is to eat a balance of highly nutritional foods, that when consumed together, do not contain too much of any one nutrient, to avoid exceeding daily recommended amounts.

Scientists studied more than 1,000 foods, assigning each a nutritional score. The higher the score, the more likely each food would meet, but not exceed your daily nutritional needs, when eaten in combination with others.

Calculated and ranked by scientists, these are the 100 most nutritious foods:

Raw or Cooked? How Best to Eat 11 Fruits and Vegetables

Find out which foods you should eat raw or cooked to maximize antioxidants.

Fruits and vegetables contain a lot of nutrients and antioxidants like carotenoids, flavonoids, and polyphenols that help prevent health issues like cancer and cardiovascular disease and can improve mood. Antioxidants help your body counteract damage caused by toxic byproducts called free radicals. Eating more fruits and vegetables also increases your vitamin C, vitamin A, vitamin B6, thiamine, and niacin, minerals, and fiber.

But it can be tricky to know how you should store and prepare fresh foods to get the most nutrients.

Luckily, when you store most fruits and vegetables, this generally does not affect antioxidants levels. In fact, antioxidant levels can even go up in the few days after you buy the fruits and vegetables. But when you start to see the fruit or vegetable spoil and turn brown, that usually means that they have started to lose antioxidants. The main exceptions are broccoli, bananas, and apricots, which are more sensitive and start to lose their antioxidants during storage within days, so eat those sooner than later.

Whether you should cook or eat raw fruits or vegetables to maximize antioxidants varies. Some vegetables like mushrooms, asparagus, cabbage, and peppers gain certain antioxidants after they are cooked.

1. Tomatoes: Cooked may be better than raw.

Storage tip: Even though this will make shelf life shorter, store tomatoes in room temperature since tomatoes can lose antioxidants (and flavor) when stored in cooler temperatures.

Cook your tomatoes to release higher levels of lycopene and total antioxidant activity. You can cook them for up to 30 minutes at 190.4 degrees Fahrenheit (88 degrees Celsius). Lycopene is found in red fruits and vegetables like watermelon, red bell pepper, and papaya and has been linked to lower rates of cancer.

Raw tomatoes have less overall antioxidants, but have more vitamin C.

2. Carrots: Cooked may be better than raw.

Cook your carrots to get more beta-carotene, an antioxidant that gets converted in your body to vitamin A, which is good for your eyes and immune system. Sous Vide carrots for best results. Steaming or boiling carrots preserves more antioxidants than roasting, frying or microwaving carrots. If you’re in Top Chef mode and want to maximize antioxidants, try sous vide carrots, which has even more antioxidants than steamed carrots.

3. Broccoli: Raw and cooked.

Storage tip: Keep broccoli wrapped in packaging in the refrigerator at 1 degree Celsius (or 33.8 degrees Fahrenheit). Unlike most vegetables, broccoli tends to lose antioxidants faster than other vegetables when stored without packaging, particularly when it starts to lose its color and turn yellow. Wrap the broccoli in microperforated or non-perforated packaging to keep antioxidants for longer.

If you eat raw broccoli, you’ll get higher levels of an enzyme called myrosinase, which creates helpful compounds like sulforaphane, which blocks the growth of cancer cells and helps fight Helicobacter pylori, a bacteria responsible for stomach ulcers. Myrosinase is sensitive to heat and thus destroyed during cooking.

Cooked broccoli and other cruciferous vegetables like cauliflower, increases indole, which is thought to be protective against cancer. Steamed broccoli has also better potential to reduce cholesterol than raw broccoli.

Sous vide or steam broccoli to keep antioxidants and nutrients. Boiling 9-15 minutes causes the loss of up to 60 percent of nutritious compounds become leached into the water. Stir-frying and a combination of boiling and stir-frying (common in Chinese cuisine) causes the most loss of vitamin C and nutrients. Steaming allows broccoli to retain better color and texture.

4. Cauliflower: Raw and cooked.

Fresh cauliflower has 30 percent more protein and many different types of antioxidants such as quercetin. Raw cauliflower keeps the most antioxidants overall, but cooking cauliflower increases indole levels.

Don’t boil cauliflower in water because that loses the most antioxidants. Water-boiling and blanching causes the worst loss of minerals and antioxidant compounds in cauliflower because many of the nutrients get leached into the water. Steam or sous vide cauliflower to maintain nutrients.

5. Brussel Sprouts, cabbage: Raw and steamed.

Brussel sprouts and cabbage are cruciferous vegetables rich in compounds protective for cancer. One study found that people who consumed about 300 grams or two-thirds pound of Brussels sprouts daily for a week had higher levels of a detox enzyme in the colon, which helps explain the link between eating cruciferous vegetables and lower risk of colorectal cancer.

Raw Brussels sprouts give you the most folate and vitamin C. Steaming Brussels sprouts can release more indole compounds (but they arguably taste best when roasted!).

6. Kale: Raw and blanched.

Kale has beta-carotene, vitamin C, and polyphenols. Cooking kale significantly lowers vitamin C and overall antioxidants. Keep kale raw or, if you prefer cooked, blanch or steam kale to minimize antioxidant loss.

7. Eggplant: Cooked and grilled.

Grill eggplant to make it a lot richer in antioxidants compared to raw or boiled (and it tastes a lot better too). Don’t forget to salt your eggplant slices before cooking to get rid of excess moisture and bitterness.

8. Red Peppers: Raw and cooked (stir-fry, roasted).

Red peppers are a great source of vitamin C, carotenoids, polyphenols, and other phytochemicals. Raw red peppers provide more vitamin C because vitamin C breaks down with heat. But other antioxidants like carotenoids and ferulic acid go up when red peppers are cooked.

Stir-fry or roast red peppers. Do not boil red peppers—boiling red peppers loses the most nutrients and antioxidants. Stir-frying and roasting actually preserves red pepper antioxidants, more than steaming.

9. Garlic and onions: Raw and cooked.

Garlic and onions have been linked with foods that help fight high blood pressure. Red onions have the highest amount of quercetin, a type of flavonoid family antioxidant thought to protect against certain forms of cancer, heart disease, and aging.

Garlic and onions are pretty hardy when cooked. You can blanch, fry, and even microwave them without changing their antioxidant levels by much, so prepare them however you like.

10. Artichokes: Cooked.

Cook your artichokes in order to boost their antioxidants. Steam artichokes to boost antioxidants levels by 15-fold and boil them to boost them by 8-fold. Microwaving them also increases an artichoke’s antioxidants. But don’t fry them– that plummets flavonoids, a type of antioxidant.

11. Blueberries: Raw and cooked.

Blueberries are one of the fruits with the highest levels of antioxidants, and you can eat them raw or cooked to get the most antioxidants. One study found that some type of antioxidants levels went up with cooking blueberries, while others went down.

Here are some final general tips:

Avoid deep-frying. Bad news for vegetable tempura fans: Deep-frying vegetables creates free radicals from the hot oil. Not only are free radicals damaging for the body, but the vegetables lose much of their antioxidants in the process.

Fresh is generally better than frozen. Vegetables like spinach and cauliflower can lose B vitamins in the process of being frozen.

At the end of the day, prepare your fruits and vegetables so that you’ll be more likely to eat them. As long as you stay away from the deep fryer, fresh fruits and vegetables will generally give you a lot more nutrients and antioxidants than processed foods.

Which Bread Is Best For You — Whole-Grain, Multigrain or Whole Wheat?

Hint: Check the label first and foremost

Gone are the days of eating white bread. Many people are aware that whole-grain has more nutritional heft than white, fluffy, overly milled breads, but it’s not always easy to pick a good loaf when you’re at the grocery store.

Sometimes, a refined loaf of bread can masquerade as something more nutritious. Patrol the bread aisle and you’ll see terms like whole wheat, multigrain, seven-grain, 12-grain, all-natural, organic and enriched, to name a few. Who wouldn’t throw up their hands trying to decide what to buy?

Dietitian Laura Jeffers, MEd, RD, LD, helps break down which bread is healthier and what you should stay far away from.

Look for ‘100%’ on labels

When browsing the bread aisle at your grocery store, look for the term “100% whole-grain” or “100% whole-wheat” on the package.

“If you’re wondering which is better, either one works,” says Jeffers. “Whole wheat is a whole grain.”

Although different grains offer different benefits, many whole-grain breads are primarily made with wheat. If you’re looking for a nice mix of grains, check your ingredient label. Primary ingredients should be listed first in order of the amount within the loaf (wheat, oats, flax seeds, barley, buckwheat, etc.).

“Be cautious of terms like ‘wheat’ or ‘multigrain’ that don’t mention a percentage,” she warns. “They sound healthy, but they’re probably made with partially or mostly refined white flour. Wheat flour is 75% white flour and only 25% whole-wheat.”

“Enriched” is another clever term that means the maker of the bread has added nutrients to an otherwise nutrient-free white bread. When you see that word on a label, put it down and look for something else.

Unless you find that 100% on the package and whole-wheat listed as the first ingredient on the label, the bread is simply a refined loaf of bread with synthetic nutrients added to replenish those natural nutrients lost in the milling process.

Good bread makes your body happy

The benefits of eating 100% whole-wheat or whole-grain far surpass just the taste. Eating whole-grain foods within an overall healthy diet helps to lower your risk for many diseases, including:

Whole-grains are also rich in protein, fiber, B vitamins and many other nutrients that help to lower blood pressure, reduce gum disease, strengthen the immune system and help control weight. The Whole Grains Council reports that benefits are greatest with at least three servings per day, but every whole grain helps.

Say ‘no’ to substandard bread

Most other bread is made with grains that have been finely milled. The resulting flour is whiter and lighter — in more ways than one.

Not only does this refined flour look whiter and bake fluffier, but it also falls short of many of the nutrients essential to optimum health. Whole-grains begin as a whole grain kernel: bran, germ, endosperm.

The milling process mechanically removes the bran, which is the fiber-rich outer layer of the grain and contains B vitamins and other minerals. Milling also removes the second germ layer, which is rich in Vitamin E and essential fatty acids. In the end, what’s left is the starchy center, which is ground into flour for various baking purposes.

“Refined flour lacks all of those wonderful nutrients and high-starch foods like white bread can quickly raise your blood sugar levels, putting you at risk for diseases like diabetes,” she says. “That’s why you should consider nothing but the best: 100% whole wheat or whole-grain bread.”

3 Mental Problems Linked To Vitamin B12 Deficiency

The deficiency is easy to rectify with diet or supplementation.

Mental confusion can be a sign of vitamin B12 deficiency, research suggests.

People with a B12 deficiency can have problems with their memory and concentration.

Depression symptoms like low mood and low energy are also linked to the deficiency.

Low levels of vitamin B12 can even contribute to brain shrinkage, other studies have suggested.

Around one-in-eight people over 50 are low in vitamin B12 levels, recent research finds.

The rates of deficiency are even higher in those who are older.

Fortunately, these deficiencies are easy to rectify with diet or supplementation.

Good dietary sources of vitamin B12 include fish, poultry, eggs and low-fat milk.

Fortified breakfast cereals also contain vitamin B12.

People who may have difficulty getting enough vitamin B12 include vegetarians, older people and those with some digestive disorders, such as Crohn’s disease.

One study has found that high doses of B vitamins can help reduce the symptoms of schizophrenia.

Schizophrenia is one of the most serious types of mental illness.

It can cause delusions, hallucinations, confused thinking and dramatic changes in behaviour.

The study reviewed 18 different clinical trials, including 832 patients.

It found that high doses of B vitamins helped reduce the symptoms of schizophrenia.

The vitamins were particularly effective if used early on in treatment.

Dr Joseph Firth, the study’s lead author, said:

“Looking at all of the data from clinical trials of vitamin and mineral supplements for schizophrenia to date, we can see that B vitamins effectively improve outcomes for some patients.

This could be an important advance, given that new treatments for this condition are so desperately needed.”

Professor Jerome Sarris, study co-author, said:

“This builds on existing evidence of other food-derived supplements, such as certain amino-acids, been beneficial for people with schizophrenia.”

Vitamin D Reduces the Need for Opioids in Palliative Cancer

Patients with vitamin D deficiency who received vitamin D supplements had a reduced need for pain relief and lower levels of fatigue in palliative cancer treatment, a randomized and placebo-controlled study by researchers at Karolinska Institutet shows. The study is published in the scientific journal Cancers.

Among patients with cancer in the palliative phase, vitamin D deficiency is common. Previous studies have shown that low levels of vitamin D in the blood may be associated with pain, sensitivity to infection, fatigue, depression, and lower self-rated quality of life.

A previous smaller study, which was not randomized or placebo-controlled, suggested that vitamin D supplementation could reduce opioid doses, reduce antibiotic use, and improve the quality of life in patients with advanced cancer.

244 cancer patients with palliative cancer, enrolled in ASIH, (advanced medical home care), took part in the current study in Stockholm during the years 2017-2020.

All study participants had a vitamin D deficiency at the start of the study. They received either 12 weeks of treatment with vitamin D at a relatively high dose (4000 IE/day) or a placebo.

The researchers then measured the change in opioid doses (as a measurement of pain) at 0, 4, 8, and 12 weeks after the start of the study.

“The results showed that vitamin D treatment was well tolerated and that the vitamin D-treated patients had a significantly slower increase in opioid doses than the placebo group during the study period. In addition, they experienced less cancer-related fatigue compared to the placebo group,” says Linda Björkhem-Bergman, senior physician at Stockholms Sjukhem and associate professor at the Department of Neurobiology, Healthcare Sciences, and Society, Karolinska Institutet.

On the other hand, there was no difference between the groups in terms of self-rated quality of life or antibiotic use.

“The effects were quite small, but statistically significant and may have clinical significance for patients with vitamin D deficiency who have cancer in the palliative phase. This is the first time it has been shown that vitamin D treatment for palliative cancer patients can have an effect on both opioid-sensitive pain and fatigue,” says first author of the study Maria Helde Frankling, senior physician at ASIH and postdoc at the Department of Neurobiology, Healthcare Science and Society, Karolinska Institutet.

The study is one of the largest drug studies conducted within ASIH in Sweden. One weakness of the study is the large drop-out rate. Only 150 out of 244 patients were able to complete the 12-week study because many patients died of their cancer during the study.

The study was funded by Region Stockholm (ALF), the Swedish Cancer Society, Stockholms Sjukhems Foundation and was carried out with the support of ASIH Stockholm Södra and ASIH Stockholm Norr.

What The Western Diet Does To The Immune System

Diets rich in two nutrients harm immune cells in the gut, putting people at high risk of intestinal infections.

A diet rich in fat and sugar damages particular immune cells named Paneth cells that produce antimicrobial molecules keeping inflammation and microbes under control.

Highly specialised Paneth cells are located in the small intestine where nutrients from food are absorbed and sent to the bloodstream.

Western diets are high in processed foods and fat and sugar, which cause Paneth cells to not work properly.

Paneth cell dysfunction cause abnormalities in the gut immune system which in turn leads to infections (disease-causing microbes) and inflammatory bowel disease (IBD), a study has found.

Dr Ta-Chiang Liu, the study’s first author, said:

“Inflammatory bowel disease has historically been a problem primarily in Western countries such as the U.S., but it’s becoming more common globally as more and more people adopt Western lifestyles.

Our research showed that long-term consumption of a Western-style diet high in fat and sugar impairs the function of immune cells in the gut in ways that could promote inflammatory bowel disease or increase the risk of intestinal infections.”

IBD patients often have defective Paneth cells, which are responsible for setting off inflammation in the small intestine.

For instance, Paneth cells can no longer function in patients with Crohn’s disease, which is a type of IBD and marked by fatigue, diarrhoea, abdominal pain, and anaemia.

The research team examined Paneth cells of 400 adults and found that the higher the body mass index (BMI) the worse these cells looked.

Frequent consumption of foods high in sugar and fat causes weight gain and has many health consequences.

These two macronutrients generally make up more than 40 percent of the calories of a typical Western diet.

The scientists fed mice a high sugar, high fat diet and in two months they became obese and had abnormal Paneth cells.

Dr Liu said:

“Eating too much of a healthy diet didn’t affect the Paneth cells.

It was the high-fat, high-sugar diet that was the problem.”

When a healthy diet replaced the Western diet, within four weeks, the Paneth cells were restored to normal.

Dr Liu said:

“This was a short-term experiment, just eight weeks.

In people, obesity doesn’t occur overnight or even in eight weeks.

It’s possible that if you have Western diet for so long, you cross a point of no return and your Paneth cells don’t recover even if you change your diet.

We’d need to do more research before we can say whether this process is reversible in people.”

In addition, deoxycholic acid (a secondary bile acid produce by bacteria in the gut) is involved in carbohydrate and fat metabolism.

Bile acid plays a key role regarding Paneth cell abnormality since it increases the activity of the farnesoid X receptor (involved in sugar and fat metabolism) and type 1 interferon (part of the immune system active in the antiviral responses) thus hindersing Paneth cell from working properly.

The study was published in the Cell Host & Microbe (Liu et al., 2021).

Is a Plant-Centered Diet Better for Your Heart?

More evidence suggests the long-standing belief that eating low amounts of saturated fats to ward off heart disease may not be entirely correct.

A new study that followed more than 4,800 people over 32 years shows that a plant-centered diet was more likely to be associated with a lower risk of future coronary heart disease and stroke, compared with focusing on fewer saturated fats alone.

“It’s true that low-saturated fat actually lowers LDL [or bad] cholesterol, but it cannot predict cardiovascular disease,” says lead study author Yuni Choi, PhD, postdoctoral researcher in the Division of Epidemiology and Community Health at the University of Minnesota. “Our research strongly supports the fact that plant-based diet patterns are good for cardiovascular health.”

To assess diet patterns of study participants, the researchers conducted three detailed diet history interviews over the follow-up period and then calculated scores for each using the A Priori Diet Quality Score (APDQS). Higher APDQS scores were associated with higher intake of nutritionally rich plant foods and less high-fat meats. While those who consumed less saturated fats and plant-centered diets had lower low-density lipoprotein (LDL) levels, or lower levels of “bad” cholesterol, only the latter diet was also associated with a lower risk of heart disease and stroke over the long term.

Choi said targeting just single nutrients such as total or saturated fat doesn’t consider those fats found in healthy plant-based foods with cardioprotective properties, such as avocado, extra virgin olive oil, walnuts, and dark chocolate. Based on study results, she recommends those conscious of heart health fill their plates with vegetables, fruits, whole grains, nuts, legumes and even a little coffee and tea, which were associated with a low risk of cardiovascular disease.

“More than 80% should be plant-sourced foods and then nonfried fish, poultry, and low-fat dairy in moderation,” she says.

“I think in focusing just on nutrients, we oversimplify the heart [health] diet hypothesis and miss the very important plant component,” says research team leader David Jacobs, PhD, professor, Division of Epidemiology and Community Health at the University of Minnesota. “If you tend to eat a plant-centered diet you will tend to eat less saturated fats because that’s just the way the plant kingdom works.”

Following a plant-centered diet is consistent with the American Heart Association’s (AHA) existing recommendations to minimize saturated fats and emphasize fruits, vegetables, whole grains, legumes, nuts, and seeds, says Linda Van Horn, PhD, professor, and chief of the Department of Preventive Medicine’s Nutrition Division at the Northwestern University Feinberg School of Medicine in Chicago, and a member of the AHA’s Nutrition Committee.

“There is no question that current intakes of plant-based carbohydrate, protein and fat are below what is recommended and moving in that direction would be a nutritious improvement,” she says, noting, however, that this doesn’t necessarily mean everyone needs to be on a vegetarian or vegan diet.

Given that plant-centered diets have been associated with lowering the risk of other diseases, the researchers are now looking to better understand how APDQS scores impact chronic conditions such obesity, diabetes, and kidney disease. They’ll also be researching how diet affects gut bacteria as they expect eating plant-based foods provides more fiber and promotes healthy microbiomes.

“I think that diet patterns provide a really solid base for the public and policy makers to think about what a healthy diet really is,” Jacobs says.

Feeding the Brain

Our body’s control centre needs a healthy diet

“You can’t wink your eye without nutrients being involved, never mind think, remember, learn, or sleep.” So says brain expert Aileen Burford-Mason, author of The Healthy Brain: Optimize Brain Power at Any Age. Find out more about how to feed your body’s command and control centre.

When people embark on the path to healthy eating, they’re often motivated by a desire to lose weight or to help fend off disease. It’s less common for people to embrace a wholesome diet to boost the well-being of their brain.

This is something that puzzles Toronto-based biochemist, immunologist, and cell biologist Aileen Burford-Mason. An expert in orthomolecular nutrition, she says the brain requires proper nutrition to function optimally. In fact, as the most metabolically active organ of the body, the brain uses nutrients at 10 times the rate of any other tissue or organ in the body.

Our body’s command and control centre

“Over the years, it has really astonished me how many times people have said, ‘Why would the brain need food?’” Burford-Mason says. “You can’t wink your eye without nutrients being involved, never mind think, remember, learn, or sleep. There are nutrients involved in every single function of the body. The purpose to eating is to get all the essential nutrients into us, without which we can’t function.

“Because it has such high needs for nutrition, the brain may be the first to warble when we’re short,” she adds. “It may be the first place to tell us, with anxiety, depression, not being able to sleep. There’s so much evidence now that nutrition is at the root of developing dementia. It’s a huge concern.”

Burford-Mason first became interested in the body’s nutrient needs while studying biochemistry at University College in her native Dublin, Ireland. She went on to complete a PhD in immunology in England. Having emigrated to Canada in 1988, she was formerly an assistant professor in the pathology department at the University of Toronto’s faculty of medicine and director of a cancer research laboratory at Toronto General Hospital. The orthomolecular nutrition consultant is now also the author of The Healthy Brain: Optimize Brain Power at Any Age (Patrick Crean Editions, 2017).

With her book, Burford-Mason wanted to distill complex, scientific information into practical steps people can take to improve the state of their grey matter. Also known as biochemical or functional nutrition, orthomolecular nutrition (which takes its name from the Greek word ortho, meaning correct) uses diet, vitamins, minerals, and other supplements to support the body’s health and healing mechanisms.

What is commonly overlooked by doctors and the public alike, she says, is that, for optimal physiological functioning, the body needs all the nutrients all the time; these compounds all interact with and affect each other.

For instance, it’s well established that people living in Canada are likely to be deficient in vitamin D. However, for the sunshine vitamin to be metabolized, the body needs magnesium.

A well-oiled machine

“It’s like the interactivity of all the components of your car,” Burford-Mason says. “It doesn’t matter whether there’s no gas in the tank or no spark plugs or a wheel is missing; with any of those, you’re going nowhere.

“Even if it’s something small, like a wheel nut missing, eventually something will go wrong; the same thing applies to nutrition. All of the nutrients are needed all the time, and the absence of one, no matter how obscure you might think it is, can compromise the way the others work.

“People have talked about exercise and brain games for brain health; all of this is important, but you can’t keep tweaking spark plugs and making sure there’s air in the tires if you’re forgetting the gas,” she says. “Nutrition has been overlooked.”

lovebrain

Food for thought

Broadly speaking, the best thing people can do to enhance brain health via nutrition is to load up on vegetables, legumes (beans and lentils), and fruit. These foods are abundant in vitamins, minerals, fibre, and phytochemicals, which are plant-based chemicals that help reduce the risk of infections and many conditions, including cancer and heart disease. “Phytochemicals can build up in the brain and protect it from damage,” she says.

You can’t have too many vegetables, legumes, and fruit, though Burford-Mason encourages variety and cautions that people who are diabetic or trying to lose weight will want to limit their intake of fruit and starchy vegetables.

Avoid sugar. “If there is one thing that is damaging to the brain and should be left out of a diet, that is sugar,” she says. “Sugar is the new smoking. We have absolutely everything to be gained from cutting back on sugar or cutting it out. The sugar we get should come from vegetables and fruit.”

Rules for brain-healthy eating

  • Choose unprocessed foods.
  • Eat nutrient-dense foods such as eggs, fruits, vegetables, nuts, and seeds.
  • Lighten the glycemic load. Limit yourself to one serving of starchy food per day, such as bread, potatoes, rice, and pasta.
  • Eat good fats, such as avocado, seafood, nuts (especially walnuts and almonds), and olive and coconut oils.
  • Have protein at each meal. Sources include chicken, turkey, tuna, shrimp, cottage cheese, Greek yogurt, eggs, lentils, and tofu.

Tips for picking a multivitamin

If you take nothing else on a daily basis, a multivitamin should be your first choice. “They’re the core of the nutrient regimen, because it’s a little bit of everything,” says Aileen Burford-Mason. “You’re plugging gaps. They’re a jumping-off point, not a total solution.”

  • Choose a type tailored to your gender and age group.
  • Look for the widest spectrum of trace minerals; molybdenum is a good indicator of completeness.
  • Select a multi with at least 25 mg of most of the B vitamins and 400 mcg of folic acid. An imbalance of these two (too much folic acid, not enough Bs) has been linked with memory problems in the elderly.
  • You may need to supplement magnesium and vitamin C, as their levels will likely be low in a multi.

Must-have supplements

  • vitamins C, D, E, and K
  • omega-3 fats (fish oil)
  • magnesium
  • vitamin B12

The brain’s need for B vitamins likely exceeds the recommended daily intakes, especially if you exercise vigorously or work your brain hard. Although multis contain ample folic acid, it’s rare to find one that has sufficient B12. Low levels of B12 are linked to age-related cognitive decline, and prolonged B12 deficiency has similar symptoms as vascular dementia.

Additional supplements to consider

  • L-tyrosine, for stress, anxiety, and memory improvement (recommended for adults only)
  • L-theanine, for stress, anxiety, “busy brain syndrome,” insomnia, and attention deficit hyperactivity disorder (ADHD)
  • melatonin, for insomnia

These Vitamins Help Fight COVID-19

These vitamins could reduce respiratory conditions and COVID-19 infections.

Vitamin A, D, and E could help people ward off respiratory illnesses and viral infections like COVID-19.

The effect of nutrition on improving the immune system due to the human body’s complexity is not wholly clear.

However, we know for sure that some nutrients play a key part in the reduction of different infections and diseases.

Past studies show that vitamin C is effective in treating or preventing pneumonia as well as supporting white blood cells to overcome viral infections such as flu and the common cold.

Data from an eight-year survey on 6,115 UK adult patients has now found that vitamin A, D and E intake were linked to a reduction in respiratory complaints, in particular viral infections.

However, this study didn’t find any effect from vitamin C supplements or food intake on respiratory diseases.

Vitamin A and vitamin E from supplements and food intake, vitamin D supplements (but not from the diet) showed significant reductions in respiratory conditions such as colds and lung diseases including asthma.

Food such as cheese, full-fat milk, liver, dark green leafy vegetables, and carrots are high in vitamin A while wheat germ oil, nuts and seeds, avocado, and olive oil are sources of vitamin E.

olive oil

Dr Suzana Almoosawi and Dr Luigi Palla, the authors of this study, wrote:

“It is estimated that around a fifth of the general population in the UK have low vitamin D, and over 30% of older adults aged 65 years and above do not achieve the recommended nutrient intake.

Our findings are consistent with the hypothesis that supplementation is critical to ensuring adequate vitamin D status is maintained and potentially indicate that intake of vitamin D from diet alone cannot help maintain adequate vitamin D status.”

Professor Sumantra Ray from NNEdPro Global Centre for Nutrition and Health, said:

“Nationally representative data continue to remind us that micronutrient deficiencies are far from a thing of the past, even in higher income nations like the UK, and this trend is mirrored by comparable global data sources from lesser resourced countries to those with advanced health systems.

Despite this, micronutrient deficiencies are often overlooked as a key contributor to the burden of malnutrition and poor health, presenting an additional layer of challenge during the COVID-19 pandemic.”

5 Food Pairings For Maximum Nutritional Benefits

Food combining can do more than soothe a fussy tummy.

Pairing certain nutrient profiles has the potential to add up to improved absorption—and better health (while some pairings can worsen digestion). Follow these formulas for maximum nutritional benefits at every meal.

1. HUMMUS + RED PEPPER = BOOST FOR LOW IRON
“The majority of dietary iron comes from nonheme, or plant, sources, but unfortunately, it’s not usually well absorbed,” says Peggy Kotsopoulos, a New York City–based holistic nutritionist. However, vitamin C helps improve the absorption of nonheme iron. The iron-rich chickpeas in the hummus and vitamin C–rich red pepper make a great snack for women, who often need more iron, she says.

2. TOMATO + AVOCADO = IMPROVED EYE HEALTH
Tomatoes are loaded with lycopene, a key nutrient for eye health that also gives the fruit its red hue. This antioxidant is fat-soluble, though, so it assimilates better in the body if it’s eaten with some fat. “Research suggests you absorb more from the carotene-rich food when you eat it with a smart fat, like avocado,” says Elaine Magee, a Boise, Idaho–based registered dietitian. There are so many ways you can pair these two powerhouses, but we love avocado toast with sliced tomatoes.

3. COTTAGE CHEESE + PINEAPPLE = POSTWORKOUT MUSCLE REPAIR
It’s important to refuel the right way following a serious Spinning class or an intense jog. After your workout, have a snack that includes protein (like cottage cheese) and a high-gastrointestinal carbohydrate (like pineapple). “Together, they replenish muscle and liver glycogen stores and cause an insulin release, which in turn helps push amino acids straight to muscle cells, which helps build and repair exactly where you need it,” says Kotsopoulos.

4. KALE + MUSHROOMS + OLIVE OIL = BETTER BONE DENSITY
Among the many nutritional benefits of kale is vitamin K, which helps transport calcium from your blood to your bones, acting as the glue that makes bone-enriching calcium stick. Studies have shown that a combination of vitamin K and vitamin D (found in mushrooms) helps prevent bone fractures, even in people already experiencing bone loss. Add some olive oil to a meal with these fat-soluble vitamins (an omelette, perhaps) and—bingo—major bone-health benefits. But not just any olive oil will do; opt for the extra-virgin version. “You’ll get more of the 30-plus phytochemicals from an olive oil that’s minimally processed,” says Magee.

5. SALMON + ALMONDS = HEART HEALTH
Omega-3 fatty acids, especially those found in cold-water fish, like salmon, may reduce the risk of blood clots, promote normal blood pressure and lower the risk of heart disease. If you pair salmon steak with ground almonds (or another nut, such as walnuts), a plant-based source of essential fatty acids, you’re packing a more powerful wallop for cardiovascular health. “And they naturally go together,” notes Magee. (Think almond-crusted baked salmon!) There’s a lot of wisdom in cuisine from certain cultures, especially from areas of Asia and the Mediterranean, where these types of pairings often come up, she says.

DID YOU KNOW?
The components in some foods work in combination with themselves when eaten whole, says Magee. “Apples are a good example where the compounds in the skin complement those in the flesh,” she explains. “You’re much better off to eat them with the skin on.” Same goes for ground flaxseeds and oats. “You’re missing out on so much if you eat only flax oil or oat bran—your body wants it all!”

If You Want a Nutritious Breakfast,
There Are Better Food Pairings Than Avocado And Toast.

Skip the avocado toast — there are healthier food pairings

If you’re trying to eat a healthy breakfast, put down the avocado toast. Choosing the right food pairings is as important as picking healthy foods when it comes to nutrition.

Writing for the Daily Mail, nutritionist Rob Hobson of Healthspan broke down how pairing the wrong foods together can negate their health benefits.

“The food pairing choices you make will have a very real effect on your energy, how quickly you feel hungry again after eating – and therefore your weight,” Hobson wrote for the Mail.

For an example, he cited a recent Illinois Institute of Technology study on avocado toast. Avocado can help control blood sugar and suppress hunger on its own, but when eaten with white bread, the carbohydrates in the bread mostly negated those benefits. The study showed that fats like avocado are healthy, and that carbs should be eaten only in moderation – and not in their processed form, Hobson said.

Another example: Beef chili with beans. Beef is high on iron, Hobson noted, but the phytates in beans can bind with that iron and keep it from being absorbed. Adding in plenty of vitamin C-rich vegetables like red bell peppers can boost iron absorption.

So what are some better food pairings? Hobson offered up several suggestions:

  • Sweet potatoes and Greek yogurt. Sweet potatoes keep blood sugar stable thanks to slowly digested carbs, and Greek yogurt packs protein.
  • Oats and banana. Oats are a fiber and can keep you feeling full longer. Bananas are a prebiotic and may help control a hormone that makes you hungry. Nut butter and banana make another good pairing.
  • Smoked salmon and scrambled egg. This “double whammy” of protein and healthy fats (including omega-3 fatty acids) can help you feel full longer. Egg on whole-grain bread is another good option.
  • Vegetable soup with beans, lentils or peas. The water content in soup can help you fill up faster, and the protein and fiber in legumes can extend that feeling of fullness.

Other great food pairings are yogurt topped with dried fruit and nuts, salad with quinoa, or beans and brown rice.

“[Satiety is] particularly important for weight management as it can help to ward of hunger pangs and the temptation to snack between meals,” Hobson wrote. “Therefore, understanding which foods are more satiating and how to put meals together using them will help you to control how much you eat later on in the day.”

The 20 Healthiest Fruits You Can Eat, According to a Nutritionist

Yet another reason to buy more watermelon.

Watermelon
Watermelon is 92% water, making it a great choice for hydration. Your food provides about 20% of your fluid intake, and eating water-packed snacks like watermelon can help you avoid subtle, headache-spurring dehydration. Because fruit is high in water, potassium, and magnesium, it helps to offset excess sodium in your diet, too.

Apples
An apple a day may in fact keep your cardiologist away. Evidence has shown that frequent apple consumption may reduce total cholesterol, which can help reduce your risk of heart disease. That’s thanks to the phenolic compounds — antioxidant compounds that help to promote healthy cellular function and proper blood flow — found in apple skins. The combo of vitamin C, fiber (about 5 grams per medium apple), and phytochemicals makes them a smart household staple for your whole family.

Mangos
Munch on mango for a summery, delicious tropical treat filled with vitamin C, potassium-, and beta-carotene. We love making a big batch of mango-filled skewers and loading up the fridge or freezer, so they’re always on hand when you need a nosh. Plus, the prep gets your little ones involved in the kitchen, and that kabob adds an extra layer of fun!

Kiwis
In addition to the vitamin C, potassium, and antioxidants you’ll get from kiwi, the combination of folate, magnesium and B-vitamins also found in this fruit can help you chill out. Some (early) research has linked eating kiwi as a pre-bedtime snack with an easier time falling asleep!

Cherries
Feeling stressed? Grab a handful of cherries. In addition to their multitude of antioxidant benefits, these little stone fruits contain quercetin, a type of antioxidant linked to promoting feelings of calmness.

Bananas
Rich in soluble fiber, bananas are an easy grab-and-go snack that can help lower cholesterol. For an extra heart-healthy boost, slice bananas on top of morning oats with a tablespoon of chia seeds and walnuts. It’s a heartier, energy-packed breakfast loaded with fiber, vitamin B6, potassium, magnesium, vitamin C, and manganese.

Oranges
You already knew that oranges came packed with vitamin C, but get this: Citrus fruits have been shown to have anti-inflammatory, antioxidative and anti-cancer properties, according to research published in Chemistry Central Journal.

Grapes
Grapes contain polyphenolic* compounds with antioxidant properties, which may help reduce cellular damage. Adding grapes (about 1–2 cups per day) to your diet can help to protect your body’s tissues and decrease markers of inflammation.

*polyphenol 
Any of a large group of colorful phytochemicals found in plants, many of which are antioxidants.
Polyphenols include several thousand flavonoids, including flavanones, anthocyanidins, isoflavonoids, and catechins.

Guava
Give your immune system a boost with guava. They’re rich in vitamin C, potassium, and fiber.

Cantaloupe
Cantaloupe is high in potassium, vitamin C, and folate. The flavonoids found in melon have anti-inflammatory, blood sugar-stabilizing, and immune-boosting properties. Plus, water-filled cantaloupe offers a hydration boost.

Strawberries
Strawberries are a great source of antioxidants — especially vitamin C. Just one cup of halved strawberries packs about 150% of your daily value. The same serving also contains about 80 calories and up to 9 grams of fiber, a combo that helps you enjoy maximum flavor and fullness for minimal calorie cost.

Grapefruit
Like other citrus, grapefruit packs tons of vitamin C. Research has shown that consuming grapefruit improves blood pressure and may help to lower cholesterol levels.

Blackberries
Berries provide nature’s perfect snack: They’re deliciously sweet, satisfying, and nutrient-packed. One cup of berries can provide about half of the vitamin C you need each day. Plus, the antioxidants found in berries have been linked to reducing your risk of a whole host of chronic diseases, thanks to their cell-protecting properties. Our favorite way to eat any type of berries? Swap them for jam in PB&J to add extra fiber, more antioxidants, and less sugar than concentrated, sugary jelly.

Avocados
Avocado is a unique fruit (yep, it’s a fruit!) because of its low sugar content. It also provides heart-healthy fatty acids and magnesium, a key mineral linked to neurological and muscular function.

Plums
Plums have been shown to have anti-inflammatory benefits that may help to boost cognition. Choose dried prunes for even more calcium and magnesium, which have been linked to decreasing your risk of osteoporosis.

Blueberries
Since they’re loaded with polyphenolic compounds, eating more blueberries can protect your heart by benefiting blood vessels and deterring harmful plaque or damage. The fiber in berries also slows down the rate of digestion in your GI tract, steadying the release of sugar into your bloodstream and offering a longer-lasting energy boost.

Lemons
Lemons are high in vitamin C, folate, potassium, and flavonoids. Flavonoids have been linked to reducing your risk of cognitive decline by enhancing circulation and helping to protect brain cells from damage.

Raspberries
Raspberries are one of the highest-fiber fruits, with one cup containing 8 grams. As a nutrient-packed choice, raspberries provide antioxidants and blood-sugar stabilizing benefits, especially when combined with a source of protein. Add ’em to your breakfast to boost energy levels and stay satisfied until lunchtime.

Pears
Besides vitamin C and fiber (25% of your daily value!), a single juicy pear will also help keep you hydrated.

Pomegranate
One cup of these petite treats packs up to 7 grams of filling fiber and 10% of the potassium you should get per day. Use them in savory entrées or sprinkle into salads for a hint of sweetness.

What Is Folic Acid, Why Do You Need It And What Foods Have It?

What Is Folic Acid?

Folic acid is the synthetic version of the folate, a B vitamin that’s vital for the formation of red blood cells. It also plays a part in helping the body’s nerves function properly. The vitamin is essential in helping DNA form within cells, “allowing each cell to replicate perfectly”, according to the BDA, the association of British dieticians.

If you don’t have enough folic acid in your body, it can cause a form of anaemia – where blood cells have reduced ability to carry oxygen around the body – which causes tiredness, weakness and fatigue. People with a deficiency might also suffer from diarrhoea, loss of appetite, weight loss, headaches, heart palpitations, a sore tongue and behavioural disorders.

Why Is It Important For Pregnant Women?

Folic acid fortification – the process of folic acid being added to grain products – has already been adopted in more than 60 countries worldwide, including Australia, Canada and the US.

The government’s 12-week consultation on whether folic acid should be added to flour follows years of campaigning by charities including Shine, which represents people with the birth defect spina bifida.

Pregnant women are advised to take a folic acid supplement before conceiving and for the first 12 weeks of pregnancy to cut the risk of birth defects. But some women forget to take the supplement, do not follow advice or do not discover they are pregnant until it is too late.

Neural tube defects (NTDs) – birth defects of the brain, spine or spinal cord – occur when an opening in the spinal cord or brain remains from early on in human development. “Folic acid can prevent NTDs, but only if taken very early in the pregnancy, and really before conception,” says Clare Murphy, director of external affairs at Bpas.

“Currently, women are advised to take folic acid supplements during the early stages of pregnancy, but around half of UK pregnancies are unplanned, which means that many women have already missed the window to take folic acid by the time they realise they are pregnant.”

Around 1,000 pregnancies are affected by NTDs each year in the UK and more than 40% of cases are fatal. Under plans to fortify flour, experts predict that around 200 birth defects a year could be prevented.

Public health minister Seema Kennedy said the move would also help women from the poorest areas who are less likely to take folic acid supplements. “It is right that we do all we can to protect the most vulnerable in society,” she added.

 

Do Men Need It Too?

Folic acid is important for everyone, regardless of their sex. According to the BDA, men, children and women who are not likely to become pregnant should be able get sufficient amounts of folate (the form of folic acid occurring naturally in food) by eating a healthy diet.

It’s been reported that folic acid can help protect the heart and cardiovascular system, boost sperm count, and decrease the risk for certain cancers. Some evidence suggests it might even reduce the risk of mood disorders.

What Foods Contain Folate (Folic Acid)?

  • Spinach
  • Kale
  • Brussels sprouts
  • Cabbage
  • Broccoli
  • Beans and legumes (ie. peas, blackeye beans)
  • Yeast and beef extracts
  • Oranges and orange juice
  • Wheat bran and other whole grain foods
  • Poultry
  • Pork
  • Shellfish
  • Liver
  • Fortified foods (ie. some brands of breakfast cereals – check the label).

How Much Should You Have?

Adults and children over 11 years old are recommended to have 200μg (micrograms) of folate daily, according to the BDA. You can get enough folic acid from food alone – many cereals have 100% of your recommended daily value of folic acid. Look on the outside of packets for the nutritional chart or the ‘contains folic acid’ symbol.

Women trying for a baby are advised to have 200μg plus a supplement. For pregnant women, the advice is to take 300μg plus a 400μg supplement during the first 12 weeks of pregnancy – but consult your doctor first, especially if you’ve had a pregnancy previously affected by neural tube defects or if you have diabetes.

Breastfeeding mothers are advised to make sure they’re having 260μg a day, to help their child’s development.

Should You Take Folic Acid Supplements?

While pregnant women are strongly advised to take folic acid supplements, the rest of the population should be able to get enough providing they eat a balanced, nutritious diet. BDA suggests those aged over 50, or those with a history of bowel cancer, should take no more than 200μg/day per day.

Potential side effects of taking additional supplements daily include nausea, loss of appetite, trapped wind or bloating – although the NHS notes these symptoms are usually mild and don’t last long.

If you have any of the following, you should speak to your doctor before having folic acid supplements:

  • An allergic reaction to folic acid or any other medicine
  • Low vitamin B12 levels or pernicious anaemia
  • Cancer
  • Kidney dialysis
  • A heart stent
