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!

9 Seeds You Should Be Eating

Chia Seeds

Chia has come a long way since it first sprouted out of funny pottery in TV commercials. Today, these seeds are best known as a super food, and with good reason. Just 1 ounce (that’s 2 tablespoons) has nearly 10 grams of fiber. Ground in a blender, chia seeds make the perfect crunchy topping for yogurt or vegetables. When you soak them in a liquid, such as juice or almond milk, they get soft and spoonable: a smart swap for pudding.

Wild Rice

Surprise! Wild rice isn’t rice at all — it’s actually a grass seed. It’s higher in protein than other whole grains and has 30 times more antioxidants than white rice. It also provides folate, magnesium, phosphorus, zinc, vitamin B6, and niacin. It cooks up tender and fluffy in a rice pilaf, and the warm grains are a hearty addition to green salads.

Pumpkin Seeds

If you’ve ever roasted a batch of these after carving your annual jack-o’-lantern, you know they make a great snack. And a healthy one, too. Pumpkin seeds are rich in magnesium, an important mineral that boosts your heart health, helps your body make energy, and powers your muscles. Eat them year-round as a soup or salad topper, with cereal, or in homemade trail mix.

Pomegranate Seeds

Also called arils, these are the sweet, jewel-like beads you strip from the inside of the fruit. They’re high in vitamin C and antioxidants. A full cup of pomegranate seeds has fewer than 150 calories, making it good for a light snack. Tossed in a salad or whole-grain dish, they add a juicy pop of flavor and color to your dinner plate.

Quinoa

If you’re looking for healthy sources of protein, quinoa has you covered. The grain-like seed packs 8 grams per cup. It cooks up like rice and can fill in for pasta and other grains in many of your favorite dishes. You can also use it as a gluten-free breading for dishes like chicken fingers. Make a batch instead of oatmeal for a breakfast porridge that will start your day with more protein, fiber, and iron.

Flax Seeds

Humans have been eating these for good health as far back as 9,000 B.C. If you don’t eat enough fish, adding flax to your diet can help you get omega-3 fatty acids, the healthy fats that are good for your heart. It’s the best plant source of this important nutrient, and it gives you a good dose of fiber, too. When the seeds are ground into flax meal, they may help lower blood pressure. Flax has a nice, nutty flavor. Add a scoop to oatmeal, your pancake batter, or salads.

Hemp Seeds

Their mild, nutty flavor pairs well with savory dishes. They also have plenty of protein: 2 tablespoons has 10 grams, even more than flax or chia seeds. Hemp is also a good source of omega-3 fatty acids. You can use the seeds whole, sprinkled on salads or whole-grain dishes, or look for hemp milk to replace your usual dairy.

Sunflower Seeds

These tender kernels are every bit as good for you as they are tasty. A 1-ounce serving has about half your daily vitamin E. They’re also high in healthy fats. Add them to your next batch of veggie burgers for extra flavor and nutrition. Sunflower seeds also make a great addition to your morning smoothie. And, of course, you can just keep snacking on them right out of the bag.

Sesame Seeds

Those little white dots on your hamburger bun aren’t just there for decoration. The sesame seed is one of the most versatile ingredients out there. Sesame oil, a smart pick for salad dressing, is high in a kind of fatty acid that may lower the bad type of cholesterol. Ground to a paste, they turn into tahini, a peanut butter sub for those with nut allergies. (It’s also a main ingredient in hummus.) The whole seeds are rich in fiber and protein. They add crunch and flavor to vegetable stir fries.

Top 10 Plant-Based Proteins To Add To Your Daily Routine

BY MEGHAN TELPNER    JANUARY 10, 2015

We all know protein is important. But even if we’re vaguely aware that we need to watch our protein intake, it’s easy to write it off as something only body builders or people on strict diets need to worry about. For women especially, it’s not uncommon to go without a good source of protein until the evening meal.

Protein is about more than building muscle. Each and every body part requires protein to function, from red and white blood cells to hair and skin (all made of protein.) Eating protein at every meal stabilizes our blood sugar levels, helping with everything from mood to weight management to nervous system health.

So how do we boost our protein intake without resorting to a big hunk o’ steak? It’s easy to get more protein in your diet without sacrificing your favorite meals. Power up your existing favourites with these easy-to-use plant-based sources of protein.

1. Fermented Protein Powder

Health Benefits: While regular vegan protein powders can sometimes be difficult to digest, the fermented variety supports healthy gut bacteria.

How To Use: Blend it in with your morning smoothie.

2. Ground Flaxseeds

Health Benefits: On top of being high in protein, flaxseeds are also a good source of plant-based omega-3 fatty acids. Their fiber content and mucilaginous nature also make them great for gut health.

How To Use: Sprinkle ground flaxseeds onto oatmeal or cooked veggies for a nutty flavour. You can also add ground flaxseeds to homemade baked goods. Recent studies have found that cooking flaxseeds leaves the omega-3 content intact.

3. Chia Seeds

Health Benefits: Like flaxseeds, chia seeds are high in protein and omega-3 fatty acids. Because they can absorb so much liquid (becoming a chia “gel”), they can also help prevent dehydration.

How To Use: Chia seeds can be added to smoothies, sprinkled on porridge, used to make puddings, or even as a grain-free “breading” for chicken or fish (if you eat it!).

4. Sunflower Seeds

Health Benefits: High in protein, sunflower seeds are also anti-inflammatory, which can help with symptoms of conditions like asthma and arthritis.

How To Use: Sunflower seeds can be sprinkled on salads and porridge. Ground sunflower seeds can also be used in place of flour to dust meats or added to grain-free baking recipes.

Sesame Seeds – Ten Amazing Health Benefits Of This Super-Seed

5. Nut Butters

Health Benefits: High in healthy fats and protein, nuts are wonderful for balancing your blood sugar levels, and using all-natural nut butters is a great way to get them in your diet.

How To Use: Add a scoop of almond butter to your green smoothies, spread some cashew butter on a homemade gluten-free muffin or replace the maple syrup on your oatmeal with a spoonful of your favourite nut butter variety.

6. Spirulina

Health Benefits: While “green” isn’t normally the color you’d think of when it comes to protein, this algae is actually a 65% highly-digestible protein. It’s also incredibly high in calcium, making it great for bone health.

How To Use: Spirulina makes for awesome addition to a green smoothie. It can be strong-tasting, so start slow!

7. Hemp Seeds

Health Benefits: Hemp seeds are packed with protein. They also contain the ideal balance of omega-3 to omega-6 fatty acids.

How To Use: Hemp seeds can be added to smoothies or sprinkled on top of salads. They are soft and don’t need straining, so they’re great for making dairy-free seed milk, too.

8. Alfalfa Sprouts

Health Benefits: Sprouts are rich in immune-boosting vitamin C, and alfalfa sprouts are made up of as much as 35% highly-digestible protein.

How To Use: Sprouts are an awesome salad-topper or great addition to any green smoothie. These are an easy one to grow yourself. Check out this handy sprouting tutorial.

9. Chickpea Flour

Health Benefits: Baked goods aren’t exactly the first thing protein source you’d think of, but swapping your usual flour for a high-protein, gluten-free one is a great way to add a protein boost to your day. Since chickpea flour is made of dried, ground chickpeas, it contains all the health benefits of these nutrient-packed beans, including antioxdiants, digestive support and blood sugar regulation.

How To Use: Chickpea flour works best in gluten-free baking recipes when it makes up no more than 25% of the total flour content, so mix and match it with other flours for best results.

10. Pumpkin Seeds

Health Benefits: Pumpkin seeds are high in magnesium, which key to nervous system health and is necessary for more than 300 chemical reactions in the human body. They’re also high in, you guessed it, protein!

How To Use: Pumpkin seeds can be added to your morning smoothie (use pumpkin seed butter if you don’t have a high-speed blender), used in baked goods or sprinkled on porridge. Lightly toasted pumpkin seeds also make an awesome salad topper!

Top 5 Foods For Natural Asthma Relief

Nearly 25 million Americans suffer from asthma and it is the most common chronic condition among children. Conventional treatments include steroids and asthma inhalers which can have nasty side effects. Here are some natural foods to ease symptoms.

According to the Asthma And Allergy Foundation of America, asthma accounts for one-quarter of all emergency room visits in the U.S. each year, with 1.75 million visits. In addition it accounts for over 10 million out-patient visits and just under half a million hospitalizations each year.

These figures are staggering and the annual cost of asthma to our economy is estimated to be nearly $18 billion as a result of medical treatment and loss of earnings due to illness or death (i).

It is estimated that 300 million people worldwide suffer from asthma and approximately 250,000 deaths related to the disease occur annually. By the year 2025, it’s believed that the number will grow by another 100 million or more (ii).

The usual symptoms are shortness of breath and wheezing. Prescribed medications cost the economy millions and can take a toll on our health as they can have many unwanted side effects.

Fresh organic fruits and vegetables will always be beneficial to our bodies and their function. These natural foods are rich sources of antioxidants, such as beta carotene and vitamins C and E, which can help reduce lung swelling, chest tightness and inflammation caused by cell-damaging chemicals known as free radicals.

Here are five of the most beneficial:

1. BANANAS

Research has shown that children who ate a banana each day had a 34% lower chance of going on to develop asthmatic symptoms such as wheezing. Bananas are one of the best sources of pyridoxine, commonly known as vitamin B6. Pyridoxine goes on to produce compounds which been shown to help relax bronchial muscle tissue.

Kids love bananas and they can be added to cereals, smoothies or just eaten from their skin for a nutritious and energy giving health boost.

The 5 Most Prominent Minerals In The Body and Their Use

2. AVOCADOS

Avocados contain a substance called glutathione which is known to protect cell damage from free radicals. It also works to detoxify the body of pollutants which can lead to breathing problems. They are also a rich source of vitamin E. Avocados can help in stabilizing blood sugar levels, improving cardiovascular health and protect the eyes against age related degeneration.

They are a powerhouse of nutrients and are a fantastic addition to a salad or added to a smoothie, or again eaten straight from the skin.

3. GARLIC

Garlic is another super-food as it has so many health benefits, including maintaining cardiovascular health, preventing cancer, and reducing high blood pressure. It is beneficial for asthma sufferers due to the high levels of vitamin C and it’s powerful antioxidant properties. Vitamin C neutralizes free radicals, unstable molecules that cause contraction of airway smooth muscles in asthma patients.

Raw garlic reduces the amount of histamines produced in the body so easing any allergic reactions in asthmatics which normally promote inflammation.

Garlic can also boost the ability of the body to create prostacyclins. These are lipid molecules that help keep the air passages of the lungs open and thus promote easy breathing in asthma sufferers.

4. SUNFLOWER SEEDS

Asthmas patients will benefit from eating sunflower seeds on a regular basis. They are packed full of nutrients including potassium, magnesium and vitamin E. In addition one cup contains a third of the daily recommended amount of selenium which is a mineral linked with a whole raft of health benefits but in particular is known to help individuals that struggle with asthma by reducing the various symptoms such as shortness of breath and wheezing.

Sunflower seeds are relatively calorific but eating these mild nutty seeds in small amounts regularly will help keep healthy lungs and airways.

5. PARSLEY

Parsley loosens phlegm and will help rid the airways of a build up of mucus. Eating parsley can relieve any tightness across the chest muscles and soothe sore throats that can be aggravated by coughing bouts when the mucus has been expelled.

It is a tasty herb versatile enough to use in many dishes or added to a juice or smoothie. Parsley leaf can also be made into a herbal tea.

These are just some of the natural treatments for asthma which can provide relief without over-reliance on chemical packed inhalers and steroid treatments. However, consult your health practitioner before stopping conventional treatment.
