Selenium: What It Does and Where To Find It

Selenium Protects a Specific Type of Interneurons in The Brain

Exactly 200 years ago, the Swedish scientist Jöns Jacob Berzelius discovered the trace element selenium, which he named after the goddess of the moon, Selene. Besides its industrial applications (chemical industry, production of semiconductors and toners), selenium is an essential trace element and indispensable for humans, many animals and some bacteria. A team led by Dr. Marcus Conrad, research group leader at the Institute of Developmental Genetics (IDG) at Helmholtz Zentrum München, showed for the first time why selenium is a limiting factor for mammals.

Scientific ‘by-catch’ solves decades-old mystery

The scientists have been investigating for years the processes of a novel type of cell death, known as ferroptosis. In this context, the enzyme GPX4, which normally contains selenium in the form of the amino acid selenocysteine, plays an important role.

In order to better understand the role of GPX4 in this death process, we established and studied mouse models in which the enzyme was modified,” said study leader Conrad. “In one of these models, we observed that mice with a replacement of selenium to sulfur in GPX4 did not survive for longer than three weeks due to neurological complications.”

In their search for the underlying reasons, the researchers identified a distinct subpopulation of specialized neurons in the brain, which were absent when selenium-containing GPX4 was lacking. “In further studies, we were able to show that these neurons were lost during postnatal development, when sulfur- instead of selenium-containing GPX4 was present,” stated first author of the study, Irina Ingold.

Furthermore, the scientists were able to show that ferroptosis is triggered by oxidative stress, which is known to occur for instance during high metabolic activity of cells and high neuronal activity. “Our study demonstrates for the first time that selenium is an essential factor for the postnatal development of a specific type of interneurons,” said Dr. José Pedro Friedmann Angeli, a scientist at the IDG, describing the results. “Selenium-containing GPX4 protects these specialized neurons from oxidative stress and from ferroptotic cell death.”

Thus, the study explains why certain selenoenzymes are essential in some organisms, including mammals, whereas they are dispensable in other organisms, such as fungi and higher plants. In future investigations, study leader Marcus Conrad and his team aim to investigate how ferroptosis is triggered in cells. As a long-term goal, he wants to elucidate the role of ferroptosis in various disease conditions in order to be able to alleviate diseases, such as cancer or neurodegeneration, which are currently difficult to tackle.

10 Foods Rich in Selenium

Selenium Function

This important nutrient is vital to immune system function. Selenium works in conjunction with vitamin E, vitamin C, glutathione and vitamin B3 as an antioxidant to prevent free radical damage in the body. It’s thought to help prevent cancer by affecting oxidative stress, inflammation and DNA repair. Selenium has been found to be important to male fertility; increasing selenium levels leads to improved sperm motility. There is preliminary research that suggests that selenium supplementation may also help with asthma symptoms, but more studies are needed.

Selenium Deficiencies

Deficiencies of selenium can occur in areas where soil content of this mineral is low. Diets high in refined foods may also lead to deficiency, as selenium can be destroyed by food processing. Taking anti-inflammatory drugs may reduce the body’s supply of selenium.

Low selenium levels can contribute to autoimmune problems, such as psoriasis and thyroid disease. Low levels have also been tied to stomach, throat and prostate cancers, although more research is needed to determine if this is a cause or a result of the disease. Some studies suggest that selenium deficiency is linked to mood disorders. There’s indication that deficiencies in selenium may contribute to the progression of viral infections.

10 Selenium Food Sources

The selenium content in foods depends on the concentration of selenium in the soil where the crops were grown. The following foods are generally considered good sources of selenium:

  • Brazil Nuts
  • Sunflower Seeds
  • Fish (tuna, halibut, sardines, flounder, salmon)
  • Shellfish (oysters, mussels, shrimp, clams, scallops)
  • Meat (Beef, liver, lamb, pork)
  • Poultry (chicken, turkey)
  • Eggs
  • Mushrooms (button, crimini, shiitake)
  • Grains (wheat germ, barley, brown rice, oats)
  • Onions

Recommended Daily Allowance

  • Children (under 3): 20 mcg
  • Children (4-8): 30 mcg
  • Children (9-13): 40 mcg
  • Adolescents (14-18): 55 mcg
  • Adults 19 and older: 55 mcg
  • Pregnant women: 60 mcg
  • Lactating women: 70 mcg

Toxicity

Exceeding 400 mcg per day can lead to selenium toxicity. Side effects may include hair loss, white spots on fingernails, fatigue, dizziness, nausea and nerve damage. There’s some evidence that high selenium levels may increase the risk of squamous cell skin cancer. Another well controlled study found a correlation between higher levels of selenium and an increased risk of developing type-2 diabetes.

Because of the possibility of toxicity, selenium supplements are controversial. The safest way to ensure a sufficient level of selenium in the diet is by eating a variety of selenium rich foods, like those listed above. Brazil nuts can be very high in selenium and should only be eaten occasionally. One Brazil nut can supply a whole day’s requirement of selenium, although this can vary depending on soil conditions. A multivitamin that contains some selenium is safe for most people to take and can help to fill the gap in a diet that is lacking.

8 Foods That Fight Colds

If someone asked you which foods were good for helping fight a cold, you would probably think of things like oranges, because they are known to contain vitamin C. You might also suggest chicken soup, since this is one of the most well-known home remedies of all time. Scientific research has proven that there are benefits from eating chicken soup, but there are many other foods you can eat that will help you battle a cold. Here is a sample.

#1 Oysters

Most people know that oysters have a reputation as somewhat of an aphrodisiac, but they probably do not know that they can also help your body fight a cold. Oysters are rich in zinc, and zinc is a mineral that helps fights colds as researchers discovered when they tested the effectiveness of zinc lozenges. They found that people whole took zinc lozenges experienced cold systems for a shorter amount of time.

#2 Garlic

We all know that eating lots of garlic comes with a risk of offending some people around you due to the strong odor it can leave on your breath. When you are suffering with a cold, you may consider this a risk well worth taking, however. One of the key ingredients in garlic is called allicin, and it has proven itself as a potent antioxidant, and antioxidants help the immune system fight illness.

#3 Yogurt and kefir

Just about everyone is familiar with yogurt, but have you heard of kefir? Where taste is concerned, kefir might be described as liquid yogurt. It has a lot in common with yogurt, and that includes loads of beneficial bacteria. These tiny microbes are actually helpful to our health, and many of them take up residence in the digestive tract and help fight off bad bacteria. Both yogurt and kefir can help fortify your own private army of beneficial bacteria that will help destroy unfriendly bacteria, and help boost your immune system, making it better able to fight off a cold.

#4 Red peppers

Vitamin C often comes to mind when we think of the best way to fight off a cold, but we are probably inclined to think about things like oranges and other citrus fruits when someone mentions vitamin C. Red peppers should not be left out in the cold, however, since they are loaded with vitamin C. Just a single red pepper averages about 150 milligrams of vitamin C, which is twice the recommended daily allowance for women. Many experts believe even more vitamin C should be used to treat a cold – as much as 500 or even 1000 milligrams a day.

#5 Mushrooms

Another food you may not even consider when thinking of foods that help fight colds are mushrooms. Granted, not everyone loves these earthy-tasting fungi, but for those who cannot get enough, getting a cold means it could be time to pig out on mushrooms. The many varieties of mushrooms that are edible differ quite a bit when it comes to their nutrient content, but most of them contain antioxidants that will help give your immune system a bit more strength to kill of a cold.

#6 Sunflower seeds

These tasty seeds are popular as a snack, and are often salted and sold in individual packages in retail stores. It’s the antioxidant power of the vitamin E in sunflower seeds that makes then useful in the battle against colds. They are probably a bit healthier if you get them unsalted, especially if you suffer from high blood pressure.

#7 Brazil nuts

While we’re talking about nuts, we may as well take a little time to mention Brazil nuts. These crunchy treats not only help you fight colds, they can also help your body kill off other viruses like the flu. A medical research study from 2001 found that mice infected with a flu virus suffered from more severe inflammation if they did not have enough selenium in their system. Brazil nuts are rich in selenium, and don’t need to be eaten in great quantities to get their benefit. Just one Brazil nut contains more than the daily recommended amount of selenium.

#8 Tea

This is something that may naturally come to mind to help ease the symptoms of the common cold. Not only does it tend to make you feel better to sip hot tea when you are feeling sick, it has real cold-fighting benefits as well. Virtually all tea contains compounds called catechins which are powerful antioxidants that are effective in the fight against illness. A study conducted in Japan in 2011 found that people who took catechin supplements for five months lowered their chances of catching the flu by 75 percent! That sounds like it might be better than a flu shot!

This Nutrient Balance Reverses Brain Aging

The right balance between omega-3 and omega-6 fatty acids may help promote healthy cognitive aging, new research finds.

While we are used to hearing about the benefits of the fatty acids in fish and fish oils, that is only half the story.

Omega-6 fatty acids can come from nuts, seeds and other oils.

Typically, Western diets have too much omega-6 and not enough omega-3.

Together, a balance of these fatty acids may help to reduce age-related decline and maintain the integrity of cortical structures.

Ms Marta Zamroziewicz, who led the research, said:

“We studied a primary network of the brain — the frontoparietal network — that plays an important role in fluid intelligence and also declines early, even in healthy aging.
In a separate study, we examined the white matter structure of the fornix, a group of nerve fibers at the center of the brain that is important for memory.”

The researchers examined the levels of polyunsaturated fatty acids in adults aged 65 to 75, along with their brain structure.

The best balance of fatty acids for brain health.

Ms Zamroziewicz explained that it takes more than just fish and fish oils to keep the brain healthy with age:

“A lot of research tells us that people need to be eating fish and fish oil to get neuroprotective effects from these particular fats, but this new finding suggests that even the fats that we get from nuts, seeds and oils can also make a difference in the brain.”

A second study found a link between a balanced amount of omega-3 and omega-6 fatty acids and greater memory preservation in older adults.

Ms Zamroziewicz explained:

“These findings have important implications for the Western diet, which tends to be misbalanced with high amounts of omega-6 fatty acids and low amounts of omega-3 fatty acids.”

Professor Aron Barbey, who co-authored the study, said:

“These two studies highlight the importance of investigating the effects of groups of nutrients together, rather than focusing on one at a time.
They suggest that different patterns of polyunsaturated fats promote specific aspects of cognition by strengthening the underlying neural circuits that are vulnerable to disease and age-related decline.”

The study was published in the journal Nutritional Neuroscience (Zamroziewicz et al., 2017).

A Gut Makeover for the New Year

If you’re making resolutions for a healthier new year, consider a gut makeover. Refashioning the community of bacteria and other microbes living in your intestinal tract, collectively known as the gut microbiome, could be a good long-term investment in your health.

Trillions of microbial cells inhabit the human body, outnumbering human cells by 10 to one according to some estimates, and growing evidence suggests that the rich array of intestinal microbiota helps us process nutrients in the foods we eat, bolsters the immune system and does all sorts of odd jobs that promote sound health. A diminished microbial ecosystem, on the other hand, is believed to have consequences that extend far beyond the intestinal tract, affecting everything from allergies and inflammation, metabolic diseases like diabetes and obesity, even mental health conditions like depression and anxiety.

Much of the composition of the microbiome is established early in life, shaped by forces like your genetics and whether you were breast-fed or bottle-fed. Microbial diversity may be further undermined by the typical high-calorie American diet, rich in sugar, meats and processed foods. But a new study in mice and people adds to evidence that suggests you can take steps to enrich your gut microbiota. Changing your diet to one containing a variety of plant-based foods, the new research suggests, may be crucial to achieving a healthier microbiome.

Altering your microbiome, however, may not be easy, and nobody knows how long it might take. That’s because the ecosystem already established in your gut determines how it absorbs and processes nutrients. So if the microbial community in your gut has been shaped by a daily diet of cheeseburgers and pepperoni pizza, for example, it won’t respond as quickly to a healthy diet as a gut shaped by vegetables and fruits that has more varied microbiota to begin with.

“The nutritional value of food is influenced in part by the microbial community that encounters that food,” said Dr. Jeffrey Gordon, the senior author of the new paper and director of the Center for Genome Science and Systems Biology at the Washington University School of Medicine in St. Louis. Nutritional components of a healthy diet have to be viewed from “the inside out,” he said, “not just the outside in.”

One of the questions the study set out to answer was how individuals with different diets respond when they try to improve their eating habits. The scientists harvested gut bacteria from humans, transplanted them into mice bred under sterile conditions, and then fed the mice either American-style or plant-based diets. The scientists then analyzed changes in the mice’s microbial communities.

Of interest, the scientists harvested the gut bacteria from people who followed sharply different diets. One group ate a fairly typical American diet, consuming about 3,000 calories a day, high in animal proteins with few fruits and vegetables. Some of their favorite foods were processed cheese, pepperoni and lunch meats.

love-your-gut

The other group consisted of people who were devotees of calorie restriction. They ate less than 1,800 calories a day and had meticulously tracked what they ate for at least two years, sticking to a mostly plant-based diet and consuming far less animal protein than the other group, a third fewer carbohydrates and only half the fat.

This calorie-restricted group, the researchers found, had a far richer and more diverse microbial community in the gut than those eating a typical American diet. They also carried several strains of “good” bacteria, known to promote health, that are unique to their plant-based diet. “Their choices as adults dramatically influenced their gut community,” said Nicholas W. Griffin of Washington University, the paper’s lead author.

The study, published in Cell Host & Microbe, is not the first to report findings suggesting dietary shifts can induce persistent changes in a gut microbial community, said Dr. David A. Relman, a professor of medicine, microbiology and immunology at Stanford University, who was not involved in the current research. He noted that other studies had found even more profound effects.

After the human microbiota was transplanted into the mice, the mice got to eat either like typical Americans or like the calorie restrictors.

Mice that had a microbiota conditioned by the typical American diet had a weaker response to the plant-based diet. Their microbial communities didn’t increase and diversify as much. “They all responded in a predictable direction, but with not as great a magnitude,” said Dr. Griffin.

Another aspect of the study suggests the company you keep may also enrich your gut microbiota — at least in mice. At first the animals were kept in separate cages. Then, when they were housed together, the microbes from the communities conditioned by plant diets made their way into the American-diet microbiome.

It’s not clear how that translates to humans: Mice eat one another’s droppings when they live together, so they easily share the bacterial wealth. Still, it’s possible humans have other ways of sharing bacteria, Dr. Griffin said. “We know from previous work and other studies that spouses who live together will develop microbial communities that are similar to each other,” he said.

Perhaps the best way to cultivate a healthier microbiome is to eat more fiber by consuming more fruit, vegetables, whole grains, legumes, and nuts or seeds, said Meghan Jardine, a registered dietitian who was not involved in the current study but has published articles on promoting a healthy microbiota. (She is also affiliated with the Physicians Committee for Responsible Medicine, which recommends a plant-based diet.) She urges people to aim for 40 to 50 grams of fiber daily, well above levels recommended by most dietary guidelines.

“When you look at populations that eat real food that’s high in fiber, and more plant-based foods, you’re going to see they have a more robust microbiota, with more genetic diversity, healthier species and fewer pathogenic bacteria living in the gut,” she said.

5 Ways to Boost Your Energy with Food

The most common complaint I hear from people is that they are exhausted or have low energy. Fortunately, there are some simple ways you can give your energy a significant boost. Here are some of my favorites:

Give Your Mitochondria a Boost: Coenzyme Q10 is a naturally-occurring substance in our bodies and in some foods that is necessary to provide energy to our cells. Inside our cells there is a micro-sized energy manufacturing facility known as the mitochondria. Mitochondria depend on CoQ10, as it is also called, to boost energy for every cellular function, including brain functions. Unfortunately, this nutrient can become depleted as we age or experience health issues. Coenzyme Q10 is primarily found in legumes, nuts, fish and poultry.

Eat Every 2 to 3 Hours: When we’re busy, rushed or on-the-go, it’s easy to skip meals or go long periods of time between meals—the worst thing you can do for your energy levels. To keep energy high you need to prevent blood sugar spikes and drops since the resulting cascade of hormones causes an energy roller coaster ride. You may feel fine one minute and then exhausted the next. The best and easiest way to maintain balanced blood sugar levels is to eat every two or three hours. It doesn’t need to be a lot of food; just a snack will do. But, you must be consistent.

Eat zinc-rich foods: The mineral zinc is involved in dozens of chemical reactions linked to energy creation in the body, so ensuring your diet has enough zinc is critical to experience an energy boost. Zinc is also necessary for healthy blood, bones, brain, heart, liver and muscles, so if you’re lacking this vital nutrient, you can experience a wide range of deficiency symptoms. Some signs of a zinc deficiency include: acne, brittle nails, infertility, frequent colds or flu, low sperm count or slow hair or nail growth. Zinc is also essential to prostate health. For more information check out my blog “9 Simple Ways to Drastically Reduce Your Prostate Cancer Risk.” Eat zinc-rich foods like sprouts, pumpkin seeds, onions, sunflower seeds, nuts, leafy greens, beets, carrots or peas frequently throughout the day.

pumpkin seeds

To B or Not to B: There are many vitamins found within the B-Complex, including B1, B2, niacin, pantothenic acid, B6, folic acid, B12, B13, B15, B17, choline, inositol, biotin and PABA. It’s not necessary to remember all of their names, but it is important to ensure adequate B vitamin intake to experience more energy. B vitamins are essential for energy production. And, the more stressful your life is, the more your body depletes these vital nutrients. Additionally, if you suffer from seasonal allergies, that’s an additional stressor to your body. Because B vitamins are not manufactured or stored by the body, it’s imperative to get B vitamin-rich foods every day. Some of the best food sources of these nutrients include: brown rice, root vegetables, pumpkin seeds, citrus fruits, strawberries, cantaloupe, kale, green vegetables and legumes. For an added boost, take a B complex supplement (50 or 100 mg) once or twice a day.  Keeping your gut healthy is also essential to proper nutrient absorption.

Ensure that every meal or snack has some protein in it: While many diet programs would have you believe that protein equals meat, the reality is that meat takes a lot of energy to digest and tends to sit in the digestive tract for many hours. There are many other excellent sources of protein, including: pumpkin seeds, sunflower seeds, legumes like chickpeas or lentils, avocado, nuts like raw walnuts or almonds and coconut milk. The protein causes a consistent release of energy over time and helps to avoid the blood sugar energy crashes most people experience. Did you notice that pumpkin seeds and legumes keep showing up in the foods that help boost energy? When you need a quick energy boost, these foods will help supply numerous vital nutrients.  Check out “Top Vegan Sources of Protein” for more information.

I Changed My Fuel And It Changed My Health’s Trajectory

All calories are not equal. Yet we continue to count them in hopes of managing weight and health. Correcting this flawed thinking will forever change your relationship with food, calories and your weight. Changing your fuel just may change your health trajectory.

Consider the significance of changing the fuel you use in your body. It could make the difference between getting promoted, being injury and illness free, lean and healthy, and even finding romance (or not). It can, and I am living proof. When I began to think of calories as more than just a number, I lost 84 pounds, reclaimed my health and looked years younger. When I only counted calories, not considering their source, I was obese and unwell.

Many know the value of this truth about calories. Professional athletes serve as ideal evidence for this argument. The difference between first and last place is often seconds of strength, endurance and power. Having the correct balance of healthy fuel in the body can change a non-medalling effort to a gold medal day. The rituals of professional athletes on competition day extend beyond wearing lucky underwear to consuming the exact meal at the perfect time to fuel their success.

Still not sure?

Think about your own body. When we ingest junk food full of empty calories and quick-burning sugar, we get an immediate high followed by a sweat-soaked crash that sends us looking for a comfy place. Productivity grinds to a halt, our focus and attention is compromised and our body is unable to regulate blood sugar, spiraling us on a roller coaster of sugar cravings and crashes. Weight gain is often the result.

Now think about your body on a good day. A day where you started with a nourishing breakfast loaded with protein, fibre, good fat and healthy carbohydrates – maybe it was a vegetable omelet with a side of salsa and avocado, and a glass of water. Your breakfast is followed by a healthy snack before lunch, a well-balanced lunch and a clean snack mid-afternoon, and then a small but nutritious dinner. Your day was productive, your focus outstanding, you were accomplished and others noticed. You were mentally fit, but your body felt different, too. Energized, supported and able to meet your physical and mental needs for the day, your body reigned supreme.

Follow these five simple nutritional tips that will change your day from mediocre to outstanding.

1. Eat 6 small meals daily.

Our body runs best when it can not only predict its next meal, but receive nutritious support. Every meal should be comprised of quality foods that represent protein, good fat and nutritious carbs. I find that my own body works best on complex carbohydrates like leafy green vegetables, beans, nuts and seeds – I encourage you to try it out for yourself.

2. Always include good fats in each meal/snack.

Every cell in the body, including the brain, is made of fat, yet we often avoid fat because we think it will make us fat. Fat however, is critical in keeping the body healthy. Without sufficient fat, the metabolic rate slows, the brain begins to shrink and our ability to repair the body is jeopardized. Good fats are easy to consume once we know what they are. These include healthy oils such as olive and coconut oil, nuts and seeds, and nutritious fruit such as avocados. Including a handful of almonds with your meal or snack, allows you to get protein, healthy fat, fibre and complex carbohydrates in one place.

3. Eat breakfast daily.

A nutritious breakfast is not coffee paired with pastry made from processed flour and sugar. Breakfast is the most important meal of the day because it sets the tone for the entire day. Would you drive to work without gas or leave the house without shoes? The answer to both of those questions is likely no. I ask then, why would you make your body starve for nutrition first thing in the morning and ask it to do work, be productive and help you achieve success? Easy breakfast ideas can include smoothies or leftovers from the night before. It doesn’t have to be fancy, it has to be fuel.

4. Drink two to three litres of water daily.

Water is the number one deficiency in the world – we are constantly losing water not only from the obvious things like sweat, but also from the not so obvious: stress, processed foods, sugar, juices, caffeine, and all the work our brains are doing to keep us moving each day. The most abundant, accessible nutrient in North America is the one that we often forget about but is critical to our success. A dehydrated plant doesn’t grow and repair, and neither does a dehydrated body.

5. BYOS – Bring Your Own Snacks.

I get you, hunger sets in and the choices around you aren’t ideal so you reach for whatever seems to be the healthiest and hope for the best. Instead of hoping, change your trajectory and your outcome by packing your own snacks. My cooler/lunch bag contains portable items I can rely on to give me excellent fuel – hard-boiled eggs, hummus and cut veggies, or sliced apples and almond butter. Some people like to make a large lunch and break it into two portions, one for lunch and the other for an afternoon snack. Find a system that works for you and start today.

Lastly, because I know that these tips are going to make you feel fantastic, I want you to do something before you start. Take a pen and a paper (or take out your mobile phone) and write down how you feel today, what you ate, what your sleep was like, how you feel about your body, how you fit into your clothes, how productive you were at work and what your vision for the future is. Then follow these tips for three weeks and revisit what you wrote.
