Seleniumis an essential trace element that affects the rate and development of several cancer types, including cervical cancer that is one of the most common cancer forms. Cervical cancer is often treated with a combination of radiation and chemotherapy and the side effects are known to affect the bone marrow and the formation of blood platelets and blood cells. However, supplementation with selenium yeast appears to counteract these adverse effects without interfering with the treatment, according to a study that is published in Frontiers in Nutrition.

The corona crisis has shed new light on the importance of having a strong immune defense, one that protects us against virus infections in the long run. Selenium plays a vital role for a number of different reasons but, unfortunately, there is widespread deficiency which increases the risk of infections and related complications. In a new review article that is published in International Journal of Molecular Sciences, the authors look closer at selenium’s role in connection with different types of virus infections such as influenza, HIV, and hepatitis with particular focus on COVID-19. The purpose of their article is to inform about new nutritional strategies that may contribute to a strong and well-functioning immune defense – mainly when it comes to COVID-19 and virus types that tend to mutate all the time.

Selenium supports a variety of different selenoproteins and antioxidants that are important for our immune defense, circulatory system, cancer protection, metabolism, gut flora, fertility, nervous system, and general health. This is described in two meta-analyses that are published in Frontiers in Nutrition. The authors mention that there is widespread selenium deficiency in large parts of the world, Europe included, and that this is a public health problem. The big question is how much selenium we need to effectively prevent and treat many chronic illnesses.

Selenium has an overlooked role in sperm quality and healthy pregnancies. A team of scientists from Romania has looked closer at blood levels of different selenium-containing antioxidants and found that low levels are significantly correlated with poor sperm quality. The scientists also explain that lack of selenium increases the risk of pregnancy-related complications, miscarriage, and preterm delivery. Both selenium deficiencies and infertility are common problems so selenium supplementation may be worth considering. For decades, Danish farmers have added selenium to animal fodder as a way of improving the fertility and general health of the animals.

Selenium supports a number of different selenium-dependent proteins that are important for our energy turnover, metabolism, immune defense, fertility, and antioxidant protection. Selenium also has a special affinity for mercury and is therefore able to bind to this heavy metal and counteract its harmful impact on the brain, the nervous system, and other tissues. Once selenium is bound to mercury, however, the different selenoproteins are no longer able to use it. We are all exposed to a certain amount of mercury and that may result in a borderline deficiency of selenium. The problem is that other factors weigh in such as selenium-depleted crops because of the lack of selenium in the European farmland. What is important to realize is that mercury toxicity is insidious and certain fish such as predatory fish and whales in the upper part of the food chain contain large concentrations of mercury. However, therapeutic doses of selenium can prevent the toxic effect of the heavy metal, according to a new review article published in Scientific Research.

Over the past decades, numerous studies have linked low selenium levels in the blood to cardiovascular disease, cancer, increased risk of infection, thyroid disorders, and several other diseases. Due to the widespread problems with selenium deficiency, supplementation with this nutrient is of potential value to our general health. In a review article that is published in Oxidative Medicine and Cellular Longevity, the authors look at selenium’s role in connection with a host of different diseases and metabolic disorders.

Selenium is a trace element that supports over 30 essential selenoproteins, which have numerous functions. For the first time ever, a study of Mexican children reveals that lack of selenium delays the growth of pubic hairs and the development of sex organs in boys. It is a known fact that the agricultural soil in Mexico is low in selenium and that affects the entire food chain. The same is the case in Europe, for which reason farmers for decades have supplemented livestock with selenium as a way of improving fertility and preventing a number of deficiency problems. The big question is to what extent can selenium deficiency problems explain the impaired sperm quality that has been observed among young men? An estimated 500 million to one billon people worldwide get too little selenium from their diet.

Our nutritional status is of vital importance to our health and our ability to handle infections. Seleniumhas several functions in the immune system, including its role as an antioxidant and in counteracting unwanted inflammation. Selenium is also able to prevent virus from mutating and becoming more virulent or creating new waves of disease. A team of Chinese scientists have reviewed a number of studies of selenium and its key role in the defense against influenza, HIV, and other types of RNA virus. They have found, among other things, that the risk of contracting a COVID-19 infection is 10 times lower in areas where the soil is rich in selenium. Therefore, it is a huge problem that selenium deficiency due to selenium-depleted farmland is so widespread in Europe, China, Africa, and many other places.

The condition of our skin means a lot to our appearance and health, and being deficient in one or several nutrients can cause premature skin ageing. Also, things like poor wound healing, acne, herpes infections, yeast infections, eczema, psoriasis, and other skin disorders may occur. In a review article published in Medicina, scientists have looked at the role of vitamins A, C, E, D, and biotin plus omega-3 fatty acids in skin health. Studies suggest that selenium and zinc may also be important for healthy skin and anti-ageing. If you don’t get enough of these nutrients or if you simply have an increased need for them, you may consider taking a supplement.

Poor sperm quality, which is a bit of a taboo, is one of the main causes of involuntary infertility. Evidence suggests that Western diets can impair sperm quality, whereas the Mediterranean diet does the opposite. Vegan diets are somewhat controversial, according to a review article published in International Journal of Molecular Sciences. Previous research has shown that supplementation with selenium, zinc, fish oil, and coenzyme Q10 can improve sperm cell quality.

Everyone knows that exercise and sports activities are good for you, but overtraining and high-performance sport may increase your risk of oxidative stress, which is associated with acute injuries, inflammation and later risk of neurodegenerative disease such as Alzheimer’s disease and ALS (amyotrophic lateral sclerosis). It is therefore a good idea to take antioxidant supplements, as this may help prevent both acute and chronic injuries. A comprehensive article published in the science journal Nutrients looks closer at the relation between free radicals and antioxidants, which have different functions in connection with various types of physical activity. This is especially the case with vitamins A, C, and E plus selenium and zinc. It is also important to make sure to get enough vitamin D and omega-3 fatty acids for counteracting inflammation and oxidative stress.

Regular sport is good for you, whereas arduous training and high-performance sport can result in physical injuries, infections, chronic inflammation, and serious diseases due to oxidative stress. This phenomenon occurs as a result of the increased energy turnover, which produces an excess of free radicals that cause damage to cells and tissues. Oxidative stress is also associated with impaired performance, poor restitution, and faster ageing. Our only natural defense against free radicals is the presence of antioxidants, and it is especially things like vitamin C, vitamin E, selenium, zinc, Q10, omega-3 fatty acids, and turmeric that protect against oxidative damage and improve recovery time. According to a review article published in Nutrients, supplements with the right doses of different nutrients can also help boost your physical and mental performance.

Scientists have discovered traces of antibiotic-resistant super bacteria (NDM-1) in the soil of Svalbard. This archipelago is located in the arctic ocean between the North Pole and Norway, several thousand kilometers from India where the bacteria was originally discovered. This is described in a study that is published in the science journal, Environment International. Bacteria with the resistance gene NDM-1 have now spread to a number of other countries and many people have lost their lives to them. Humans are also challenged by other antibiotic-resistant bacteria, and the British health authorities consider this to be a larger threat to humans than climate change. But what causes these bacteria to develop resistance? And what vitamins and minerals are particularly important for bolstering the immune system? After all, our immune defense is our only way of protecting ourselves if antibiotics fail to work.

Swedish scientists wrote medical history when they discovered that supplementation with Q10 and selenium could halve a person's risk of dying from cardiovascular disease. Now, a 10-year follow-up of the Swedish study shows that taking these two supplements even has a notable long-term effect on cardiac function and lifespan.

There is worldwide focus on finding better ways to prevent and treat COVID-19 because of the limited effect of vaccines. It is important to understand why the infections are harmless in most cases and why only a small number of people are affected by ARDS (acute respiratory distress syndrome), which is complicated and involves hyperinflammation. What represents the real problem here and what makes these infections life-threatening is a derailed and overactive immune defense. Multiple studies have already demonstrated that lack of vitamin D increases the risk of being infected with COVID-19 ending up in intensive care, and the studies also show that vitamin D supplements have a therapeutic potential. In a new review article that is published in Clinical and Molecular Allergy, researchers look closer at the synergy between vitamin D, magnesium, and zinc in relation to their ability to regulate the immune system and as potential therapeutic agents. It is also vital to have enough selenium, a nutrient that many people lack.

Refined foods and poor dietary habits are the reasons why billions of people in the world lack essential nutrients like B vitamins, vitamin C, vitamin E, calcium, magnesium, iodine, iron, selenium and zinc. This catastrophic nutrient crisis, which even affects people in the western world, contributes to infections and pandemics, impaired fertility, poor quality of life, chronic diseases, and early death, according to a study that is published in The Lancet Global Health. The study authors call their results very alarming and believe that it is necessary for health authorities to take action now to improve public health. There is also a problem with lack of vitamin D and omega-3 fatty acids, even though they were not included in the study.

- and these compounds increase the need for iodine

We humans are exposed to a host of toxic fluoride compounds from food packaging, cookie sheets, rain clothes, impregnation agents, tap water, toothpaste etc. Effective July 1., 2020, cardboard, parchment paper, and cookie sheets that contain fluoride compounds are banned in Denmark. Fluoride poisoning increases the risk of various thyroid disorders, breast cancer, kidney diseases, ADHD, and fetal damage. At the same time, it increases the need for iodine. In fact, the symptoms of fluoride poisoning are often the same as the those seen with iodine deficiency. Read more about how to avoid fluoride compounds in the environment and how to make sure to get enough iodine.

Fish contains vitamin D, omega-3 fatty acids, selenium, and iodine, all of which are important for the fetus’ brain and development. However, fish also contains mercury and that discourages many pregnant women from eating fish. According to a new study that is published in NeuroToxicology, eating fish during pregnancy is actually not harmful at all, on the contrary, and the scientists behind the study argue that the precautionary guidelines need to be revised. Apparently, the selenium content in fish and seafood determines if mercury is dangerous or not.

Selenium is an essential trace element that supports a host of different proteins and antioxidants that are important for pregnancy. According to a new Norwegian population study that is published in the science journal Nutrients, lack of selenium during pregnancy may stunt the growth of the fetus and result in low birth weight. This may have consequences for the child’s growth, cognitive skills, and health. Selenium deficiencies are rather common in Norway and the rest of Europe and that is a problem.

Selenium is a trace element that supports well over 25 different selenoproteins, which are important for our energy turnover, blood sugar balance, metabolism, cell protection, and a host of other essential functions. A group of scientists from Rutgers University in New Jersey, USA, has just uncovered the mechanisms involved in getting selenium into the “engine room” of the cells, from where it is metabolized into the different selenoproteins. According to the scientists, this new insight into the metabolism of selenium may lead to new therapies that can treat a variety of diseases such as diabetes, metabolic disorders, and cancer.

- and supplements can often help

Depression is on the rise. The problem is often caused by inflammation in the brain. The British neuro-immunologist, Edvard Bullmore, has published the thought-provoking book called The Inflamed Mind, in which he describes the link between root canal treatment and depression, among other things. David Perlmutter, a neurologist, has written the book, Grain Brain, where he describes how gluten combined with carbohydrate overload also can cause inflammation in the brain. Depression, in other words, may occur when the blood-brain barrier is not as impermeable as assumed, and when the cytokines of the immune defense are able to cause undesirable brain inflammation. Numerous studies have shown that fish oil, vitamin D, magnesium, zinc, and selenium can improve a person’s mood by counteracting inflammation in the brain and other sites, and there is often a connection. It requires therapeutic doses, however, and it is vital that the supplements have good bioavailability, so the active substances reach the cells.

During the winter period, many people catch a cold or are bed-ridden with a bout of the flu. They may consider this to be perfectly natural, but it is actually a sign of a weakened immune defense, and that makes them susceptible to contamination. What matters is to make sure to get plenty of vitamin D, vitamin C, selenium, and zinc, all of which are nutrients that have different functions in the immune system. Some nutrients are also needed in larger quantities to tackle a beginning infection, and it is important to act quickly in order to nip the infection in the bud.
In fact, it is vital for us to be nutritionally bolstered during the winter period, where otherwise harmless virus infections can lead to complications such as herpes, bronchitis, and pneumonia, if the immune system is unable to work full throttle.

- and selenium deficiencies are widespread

An estimated 500,000 Danes suffer from some kind of thyroid disorder, the most common of which is Hashimoto’s disease, which slows down your metabolism. The formation and activation of thyroid hormones depend on iodine and selenium, and it is essential that the two nutrients are properly balanced. Having too little or too much iodine increases your risk of Hashimoto’s disease, and the same is the case with selenium, a nutrient that many people lack.
Some of the problems that are seen in people with slow metabolism are extreme fatigue, weight gain, constipation, cold sensitivity, swollen neck, and dry skin. The symptoms can vary, however, and many people still have not been given the proper diagnosis. Medical therapy with thyroid hormones will not necessarily solve the problem. In fact, as many as 20 percent of patients actually feel worse, although their blood tests appear to be normal. It is therefore important to focus more in the role of iodine and selenium in the metabolism.

Both physical traumas and critical illnesses are associated with inflammation and oxidative stress where free radicals can cause potentially life-threatening damage to cells and tissues. Traumas are estimated to be the cause of one in ten deaths. New research suggests that early intervention with selenium may shorten the hospital stay including the days spent in intensive care and reduce total mortality. This was shown in a study published in Frontiers in Nutrition where the researchers looked closer at selenium’s unique antioxidant properties and anti-inflammatory effect.

Plant-based vegan diets have become increasingly popular among young adults and they even introduce these diets to their children. It is common knowledge that vegan diets lack vitamin B12, which is why many vegans take a supplement. However, a sizeable number of vegans also lack iodine, iron, zinc, and selenium. Most studies have looked at adults but it appears that children on vegan diets also risk metabolic changes, and they have lower blood levels of vitamins A and D compared with children on normal diets. This was demonstrated in a new study that is published in the esteemed international science magazine, EMBO Molecular Medicine.

– and that may harm your fertility, metabolism, nervous system, and the growth of your child

Everyone is talking about the climate, and meat has lost popularity for a number of reasons. But let us keep our heads clear on the facts. There is a big difference between CO2 emissions, animal welfare, and the quality or quantity of meat on one hand and the nutritional aspects of meat on the other hand. Humans have been eating meat (including fish) for around two million years, and animal food sources have contributed to our large brains and development in general. Nonetheless, more and more people choose to become vegetarians, and the trend is especially popular among women. This gives rise for concern, as lack of protein, vitamin D, vitamin B12, iodine, selenium, iron, zinc and omega-3 fatty acids not only impairs fertility but even increases the risk of metabolic disorders, serious growth disturbances in children and a lot more. Some of these symptoms are insidious and therefore difficult to link to the diet.

More and more people in the Western world shift to a plant-based diet but may find themselves challenged when it comes to getting enough of certain essential nutrients. A new German study shows that most vegetarians and vegans get enough vitamin B12, provided they take supplements. However, many lack iodine and iron. Also, plant-based diet fails to deliver enough vitamin D, and many lack selenium due to the nutrient-depleted farmland. A lot of deficiency diseases are insidious, which makes it difficult to link them to the diet. It is therefore a good idea for children and adults who are vegetarians or vegans to take relevant supplements.

Telomeres are protective caps at the end of our DNA strands. You can compare them to the small plastic aglets that prevent shoelaces from unraveling. For each time a cell divides, the telomeres become shorter. The length of telomeres conveniently indicates our biological age. Diet plays a role and according to a large population study, vitamin C intake is linked to telomere length. The same is the case with Q10 and selenium, according to Swedish research. Vitamin C, Q10, and selenium serve as unique antioxidants that protect the telomeres and the cells against damage caused by oxidative stress.

Lack of vitamin E increases your risk of fertility problems, atherosclerosis, blood clots, and Alzheimer's disease. The diet contains eight different forms of vitamin E. The vitamin is also available in supplement form, either as natural or synthetic vitamin E, and there are huge differences in terms of their effect.

Selenium is important for our immune defense, thyroid gland, fertility, protection of cells, and other essential body functions that international science is very focused on. The recommended selenium intake for men and women has been increased by 50 percent. At the same time, the selenium content in the agricultural soil in the Nordic countries is rather low, which makes it challenging to get enough selenium from things like wholegrain, meat, dairy products, and eggs.

It is vital to take good care of your eyes throughout life to maintain good vision. Our eyes need a number of different vitamins, minerals, and fatty acids that are important for cellular function and for protecting against oxidative stress. In this article, you can read more about vitamin A, vitamin C, vitamin E, B vitamins, zinc, selenium, omega-3 fatty acids, and Q10 and their vital role in maintaining healthy vision. We will also look at certain antioxidants that are found in eggs, salmon, spinach, broccoli, red bell pepper, and blueberries.

According to WHO, chronic inflammation is the leading cause of death worldwide. Although it is not something that can be felt as such, chronic inflammation sets the stage for a host of different diseases. In a new review article that is published in StatPearls, the authors look closer at why chronic inflammation is so dangerous and how a healthier lifestyle with vitamin D, selenium, magnesium, zinc, and fish oil can help fight the inflammation and prevent the many different diseases and early death that follow in its wake.

Newly diagnosed cancer patients often lack selenium. Not only does this contribute to the development of the disease, but it also worsens the prognosis. An estimated one billion people worldwide are selenium-deficient and there are many things that can explain it. High-doses selenium supplementation of cancer patients seems to have a positive effect on their health and quality of life during rehabilitation, and the best effect is seen when blood selenium levels remain high, according to a German study published in Nutrients.

The trace element selenium has a vital yet overlooked role in ensuring a well-functioning immune system, and the widespread problems with selenium deficiency increase the risk of dying of COVID-19, according to a large German study that is published in the science journal Nutrients. The scientists therefore conclude that determining the patients’ blood selenium levels may provide vital diagnostic information. Also, the researchers conclude that it may be necessary to include selenium supplements in the treatment of COVID-19, especially with older people, diabetics, and those with chronic diseases that are at particular risk of life-threatening complications. The agricultural soil in Europe and other parts of the world contains relatively little selenium, which is why it is imperative to focus more on getting adequate amounts of this essential nutrient for the sake of preventing COVID-19 and other viral infections. It appears that the official recommendations – the so-called reference intake levels or RI – are not sufficient to meet the body’s actual requirements.

Decades of intensive farming have depleted the soil. As a result, crops lack up to 40% of their essential nutrients, according to a previously published study from University of Texas and a more recent one from Switzerland. Even if you stick to the official dietary guidelines, you may have difficulty with getting enough calcium, selenium, zinc, iron, vitamin B2, vitamin C, and other essential micronutrients that are required for good health.
