- but researchers warn against reduced intake levels
Even if you eat a healthy and balanced diet, it can be difficult to get enough selenium because of climate changes and nutrient depletion of the soil, especially in Europe. This was shown in a study conducted by Swiss scientists. Selenium is very important for the immune system, but how much do we need to be optimally protected against infections? There also appears to be a connection between widespread selenium deficiency and the increased rate of cancer.
- atherosclerosis, and early death
Cholesterol is an essential compound with many different functions. However, it can also turn into a potentially dangerous substance if it oxidizes and is embedded in the blood vessel walls. This oxidative process is what eventually leads to atherosclerosis. The trace element selenium protects against atherosclerosis because of its antioxidant properties and because of other mechanisms, according to a review article published in Biomedicine. This is highly relevant in our part of the world where cardiovascular disease is the leading cause of death, and where selenium deficiency is so widespread.
- which many people lack
It is not the actual COVID-19 virus that can become lethal. It is the immune system’s overreaction with hyperinflammation and a storm of cytokines that destroys healthy tissue in the lungs, the cardiovascular system, and other places in the body, according to a new article that is published in The Lancet. The capacity of the immune system determines if an infection like COVID-19 is either harmless or life-threatening. For that reason, hygienic measures, masks, isolation, and delayed vaccines are not sufficient. We also need to bolster our immune system against COVID-19 and other pandemics that may occur in the future. Let’s look closer at vitamin C, vitamin D, selenium and zinc, all of which are essential for preventing a well-functioning immune system from going off its rails. What is also worth mentioning is that many people lack these nutrients, especially older people and other exposed groups.
- because of the many antioxidants
A new Chinese study that is published in the science journal, Heart, shows that eating an egg every day can lower your risk of stroke by 26 percent. The reason is that eggs contain selenium and other powerful antioxidants that protect against atherosclerosis, and we do not get all that much selenium from our diets. Therefore, forget all about the cholesterol scare and warnings against eating eggs. That dietary advice is outdated and has done more harm than good.
It is estimated that one billion people worldwide lack selenium. This has fatal consequences for public health because it increases the risk of virus infections, thyroid disorders, cardiovascular diseases, cancer, neurological disorders, and involuntary infertility. Adding to that problem is the fact that mercury, a known environmental toxin, throws a wrench into selenium’s different functions. In the following, we have compiled a long list of studies that look closer at the consequences of selenium deficiency and the advantage of optimizing the body’s selenium status with help from supplements.
Breast cancer is the leading cancer form among women. Even though treatments have gotten a lot better the disease still has a high death toll. A Swedish-German study shows that having low levels of selenium in the blood worsens the prognosis, whereas having a higher selenium content in the blood can increase the odds of surviving breast cancer. Unfortunately, selenium deficiency is rather common in Europe. According to the scientists behind the new study, measurements of selenium status can be used to optimize blood levels of the nutrient, thereby improving treatment correspondingly.
Having higher blood levels of selenium, an essential trace element, increases a breast cancer patient’s chances of 10-year survival, according to a Polish population study that is published in the science journal Nutrients. Also, earlier research has shown that supplementation with selenium yeast can lower the risk of contracting a variety of different cancer forms. The agricultural soil in Europe is very low in selenium and that is one of the reasons why selenium deficiencies are so common. The question is how much selenium we need to optimize levels in the blood.
Apparently so. According to a new study, vitamin B3 (niacin) is a powerful antioxidant that, by means of enzyme processes, protects the body against aging and diseases caused by oxidative stress.
- or are you wasting money on the wrong supplements?
It is only natural to expect a nutritional supplement to be absorbed and deliver an effect. However, for this to happen, you must look for products with documentation. Countless multivitamin products and supplements with Q10, selenium, chromium, magnesium, and iron have very poor quality and are not properly absorbed. Our ageing process alone impairs the uptake of vitamins and minerals, and the same is the case if we lack essential fats, have too high calcium levels, or use antacids and other types of medicine – so this also needs to be taken into account.
- that are a threat to public health
Climate changes and soil depletion increase the risk of selenium deficiency, especially in Europe as shown by Swiss scientists. Selenium is an essential nutrient, and existing studies clearly show that low selenium intake increases the risk of cancer, metabolic disorders, impaired immunity, poor sperm quality, and atherosclerosis. Selenium deficiencies are therefore to be taken seriously and should be prevented one way or another. A good way to get enough of the nutrient is by taking a high-quality selenium supplement.
- and antioxidants like selenium, Q10, and melatonin play a role in prevention and treatment
There is a link between depression, dementia and Alzheimer’s disease. Also, it appears that chronic stress contributes to oxidative stress and brain cell damage. In a review article that is published in the science journal Antioxidants, researchers look closer at how oxidative stress affects the brain. They also study how antioxidants can be included in the prevention and treatment of Alzheimer’s disease, and why the most promising results are seen with selenium, Q10, melatonin, vitamin E, turmeric, and polyphenols. With regard to depression, selenium, zinc, vitamin E, turmeric, and saffron have demonstrated the greatest potential.
It is vital for sportspeople, especially those who engage in elite sports and arduous training, to be adequately supplied with dietary fuel, vitamins and minerals, as deficiencies may impair their performance and increase the risk of sports injuries, infections, anemia, osteoporosis, and hormonal imbalances.
- which is why we need enough vitamin C, selenium, and other antioxidants
Modern man is exposed to a lot of free radicals because of factors like stress, environmental toxins, etc. Free radicals are like “internal terrorists” that contribute to atherosclerosis, diabetes, Alzheimer’s disease, cancer, and a host of other diseases. Our only protection against free radicals are antioxidants from vitamins, minerals, and plant compounds. Antioxidants work in different ways. Being deficient in a single primary antioxidant such as selenium may leave the body vulnerable to oxidative stress and disease. What most people are unaware of is that free radicals are also essential, as they are a part of our energy turnover and immune defense. The question is how do we protect ourselves the best against infections, oxidative stress, and disease? What type of antioxidant do we get from dark chocolate, green tea, coffee and red wine? How does redox therapy with vitamin C in great quantities work on cancer patients? You can read more about these topics in the following.
- with links to cancer, Parkinson’s disease, and other neurological disorders
The mitochondria are the powerhouses of our cells that churn out energy in a process that involves oxygen, Q10, selenium, and other nutrients. Around 100 years ago, the German Nobel Prize winner, Professor Otto Warburg, demonstrated that even if cancer can be caused by a number of secondary factors, there is only one primary cause: alterations in the mitochondrial oxygen turnover. In his recent book, Tripping over the Truth, molecular biologist Travis Christoffersen describes how contemporary scientists confirm Warburg’s theories and says that we need to look at prevention and cancer treatment from an entirely different angle. Other studies show that Parkinson’s disease, migraine, senility, chronic fatigue, fibromyalgia, epilepsy, and other neurological disorders may be rooted in defects of the mitochondria that have many other functions besides delivering energy. It is therefore vital to take care of the mitochondria throughout life. You can read more about the ketogenic diet that optimizes mitochondrial energy turnover in different mitochondrial diseases.
Ageing is linked to uncontrolled, low-grade inflammation, also known as inflammaging, according to articles published in the journals Nature Medicine and Ageing and Disease. Although chronic inflammation is not felt directly it may set the stage for cardiovascular disease, rheumatism, Alzheimer’s disease, and cancer. Chronic inflammation may also cause virus infections like influenza and COVID-19 to become life-threatening because the immune defense suddenly overreacts and attacks healthy tissue. It is therefore vital for ageing people to protect themselves against chronic inflammation, which means getting plenty of vitamin D, selenium, coenzyme Q10, zinc, omega-3, and melatonin. These are all things that many older people often lack.
Selenium supports a host of different metabolic processes and serves as an antioxidant that protects our cells. According to recent studies, selenium also has anti-ageing properties that protect us against cardiovascular disease, cancer, dementia, and other age-related diseases. According to a review article published in Medical News Today, selenium also helps against impaired immunity and counteracts chronic inflammation, which is typically seen in connection with ageing processes. A Swedish study of healthy seniors has even showed that supplementation with selenium and Q10 has a positive effect on heart function, quality of life, and life expectancy.
There is absolutely no reason not to consume eggs, meat, butter and other cholesterol-filled foods with a good conscience. American dietary guidelines have finally exonerated cholesterol, which happens to be an essential compound. Many scientists actually claim that atherosclerosis and cardiovascular disease are both a result of inflammation and lack of specific micronutrients. It is important to pay attention to factors that are known to promote inflammation in the body and take the necessary steps by looking after your circulatory system, making healthy lifestyle choices, and possibly even using supplements.
Kidney stones is a painful and quite common problem. The diet plays a major role and according to a large American population study published in Nutrients, selenium may help prevent the condition. The authors mention that selenium-containing proteins and antioxidants have preventative mechanisms and due to the widespread problems with selenium-depleted farmland, they say that selenium supplementation may be a good way to prevent and manage kidney stones and other pathological changes.
- and increases the risk of degenerative disease and early death
It is commonly known that degenerative diseases such as cardiovascular disease, diabetes, kidney ailments, and liver diseases are often linked to poor quality of life and shorter lifespan. Supplementing with Q10, possibly in combination with selenium yeast, may have a positive influence on the mentioned conditions and lower your risk of premature death by as much as 50 percent or more. In fact, Q10 can help delay the ageing processes by protecting the heart, cardiovascular system, and cells, according to a large review article published online by NCBI (National Center for Biotechnology Information). As mentioned in this article, it is essential to use supplements that are pharmaceutical-grade in order to ensure proper absorption in blood and tissue.
– and could even make them more dangerous
Selenium is of vital importance to a strong immune defense. Still, selenium deficiency is a common problem and it increases the risk of viral infections such as influenza and the coronavirus from China, which is feared to turn into a global pandemic. It is a problem that selenium deficiency in infected animals and humans causes the virus to mutate and become more aggressive. Because of selenium’s important role as a powerful antioxidant, being deficient of this micronutrient may leave the body vulnerable to oxidative stress, which can cause tissue damage and complicate the virus infection. It is therefore important to get enough selenium at all times, as it also increases our resistance towards other viral infections such as herpes, HIV, and hepatitis, according to an article published in Nutrients.
Having too little selenoprotein P in your blood increases the risk of heart failure, according to a Swedish population study, in which the authors look closer at selenoprotein P’s role as a marker of the body’s selenium status and as a precursor of other selenoproteins. We need more than 100 micrograms of selenium daily to properly saturate selenoprotein P, but because the European soil is low in selenium it is difficult to get enough from the diet.
There are around 750,000 people in Denmark who take several medical drugs per day, and the number of users is on the rise. What many people are unaware of is that different drugs can disrupt the body’s ability to absorb or utilize one or several nutrients, especially things like B vitamins, vitamin C, vitamin D, vitamin K2, magnesium, potassium, calcium, zinc, iron, and coenzyme Q10. It is therefore vital to get sufficient amounts of the mentioned nutrients to reduce the risk of adverse effects.
- and that increases the need for selenium
Selenium is necessary for ensuring proper functioning of around 25 different enzymes – also known as selenoproteins – that are essential for energy turnover, metabolism, immune defense, fertility, and for antioxidant protection to help prevent cells and DNA from being damaged by oxidative stress. Selenium is also a so-called mercury antagonist that works by attaching itself to mercury, thereby preventing mercury’s harmful impact on the brain and nervous system. Once selenium has attached to mercury, however, it is no longer available to carry out all of its essential functions in the body. Because we are all exposed to mercury in some degree, this may cause a relative selenium deficiency that leaves our brain and nervous system particularly vulnerable to oxidative damage. In a new review article based on published research, Professor Nicholas V.C. Ralston and Dr. Laura J. Raymond explain why the toxic damage to the brain and nervous system is primarily a result of mercury’s inhibiting impact on the selenium metabolism. Selenium deficiencies are rather common, and mercury poisoning is an insidious problem, so the combination of these two problems deserves a lot more attention.
The majority of supplements with vitamins and minerals fails to extend life or protect against cardiovascular disease, although fish oil does seem to have a good effect, according to a large review from John Hopkins University. On the other hand, a Danish study shows that blood levels of vitamin D are crucial for a person’s expected lifespan, and a groundbreaking Swedish study shows that patented supplements with Q10 and selenium benefit older people by improving their cardiac health and reducing cardiovascular mortality by 50%. What matters is to use supplements that contain nutrients in the right quantity, which have a proper quality and can be absorbed by the body. In the following, you can read more about the different studies and learn how you can improve your heart health and increase your chances of a longer life.
New Year’s resolutions are often related to healthier living with better dietary choices, fewer stimulants, and more exercise. We want to stay as young and vital as possible with lots of energy. However, life is not always that simple, and nature often needs a helping hand. The following anti-ageing tips – including the essential beauty sleep – are based on a summary of articles that have all been published previously on this site.
- but specific nutrients protect you
People, who eat nutrient-depleted diets, have an increased risk of contracting cancer, according to a French study that is published in PLoS Medicine. The scientists therefore recommend labeling food to help consumers make healthier choices. In the Nordic countries, we already have the “Keyhole label” on certain healthy food items, but even if you follow the official dietary guidelines, it may be difficult to get enough vitamin D and selenium, both of which are nutrients with several anti-cancer mechanisms.
- but may he helped with Q10
Periodontal disease (tooth loss) affects most of us at some point. Because it is an insidious disease, it is important to set in with early prevention on several accounts. It is not a matter of saving your teeth and smile - your heart and cardiovascular system are also a target of the ailment.
People suffering from periodontal disease often lack Q10 in their gum tissue. This was shown as early as in 1971. In the meantime, numerous studies have demonstrated that supplements of Q10 have a positive effect on the feared disease. Because the body has difficulty with absorbing Q10 from supplements it is important to choose products that can document their bio-availability. It may also be a good idea to consider taking extra selenium, as this trace element optimizes the effect of Q10.
Q10 and selenium are powerful antioxidants that are important for the heart, cardiovascular system, and the energy turnover. As we grow older, our endogenous Q10 synthesis decreases, and many people lack selenium. A Swedish study has shown that older people who take supplements of Q10 and selenium have a 50 percent lower cardiovascular death rate. Another (more recent) Swedish study shows that Q10 and selenium also increase elderly peoples’ levels of IGF-1, a hormone with many functions in the body. The scientists assume that this helps reduce the risk of cardiac death among elderly people.
Cardiovascular diseases are widespread and one of the major causes of death. The risk is increased by factors such as ageing, diabetes, and overweight. One of the underlying causes is oxidative stress, which is an imbalance between free radicals and antioxidants. Q10, which is involved in cellular energy turnover, happens to be one of the most powerful antioxidants. According to a review article that is published in the scientific journal Antioxidants, supplementation with Q10 can reduce oxidative stress and cardiovascular mortality. It can also improve quality of life and increase the chances of survival. Generally speaking, Q10 has a huge potential for anyone with a desire to remain healthy, and it is important to choose a supplement with documented quality and bioavailability.
The immune system needs selenium every single day. Lack of this nutrient increases your risk of virus infections, inflammation, and cancer. It is a huge problem that many of us get too little selenium because of factors such as nutrient-depleted soil and unhealthy eating habits.
- and there are no side effects
Rheumatism is the most widespread chronic disease in Denmark, and many people experience a worsening of the symptoms during the winter period. The majority of people take anti-inflammatory drugs for years, but this increases their risk of bleeding stomach ulcers and other side effects, not to mention premature death. The underlying cause is chronic inflammation and it is a problem that is not properly addressed. For decades, Nobel Prize-winners and other scientists have revealed what causes chronic inflammation and how the problem in many cases can be helped with various supplements that help cure the pain. In the following, we have summarized a lot of the research that has been conducted with vitamin D, fish oil, magnesium, selenium, zinc, and glucosamine, and we have looked at why the anti-inflammatory lifestyle has become such a health trend. It is essential to use supplements that contain the different ingredients in therapeutic doses and with a quality that allows the body to absorb and utilize the active compounds.
The cells in our body are constantly renewed but they can only divide a limited number of times. It all depends on the length of their telomeres, which one can compare to the protective plastic tips at the ends of shoelaces. Every time a cell divides, its telomeres are reduced in length, bringing the cell closer to its terminal phase. Now, a Chinese study has revealed that higher selenium intake is linked to increased telomere length. Put differently, a higher selenium intake contributes to protecting the cells and allowing them to replicate more times. This may likely postpone the ageing process and extend our lifespan, and there are other studies that suggest the same. It is worth making a note of the fact that selenium deficiency is widespread in Europe and throughout the world.
A combination of the trace element selenium and the vitamin-like compound coenzyme Q10 appears to be a highly useful treatment for people with impaired cardiac function.
It’s commonly known that physical activity boosts the brain’s ability to form new brain cells – or neurons. Still, the underlying mechanisms have been a mystery to science. A team of Australian scientists, however, has recently discovered that, during exercise, mice produce a selenium-containing protein that helps the brain synthesize new brain cells. The scientists consider this to be a rather fantastic study, and it is assumed that selenium therapy may be used in the future to prevent and treat cognitive decline in people who are unable to carry out physical exercise or in those likely to be selenium-deficient. This is particularly relevant for Alzheimer’s patients and people who have suffered a stroke. It should be added that it can be quite a challenge to get enough selenium from an otherwise balanced diet in our part of the world.
In a new scientific study Danish researchers from Copenhagen University have demonstrated that methylated selenium compounds can regulate the body's immune system enabling it to better fight certain cancers. These selenium compounds are found in certain foods such as garlic and broccoli, but also in selenium yeast.
- by way of different mechanisms
There seems to be a relation between ageing, Alzheimer’s disease, and the widespread problems with selenium deficiency. According to a new study that is published in Antioxidants, scientist have revealed how different selenium-containing proteins can affect pathological processes in the brain that are known to cause Alzheimer’s disease. They believe selenium may have therapeutical potential in the treatment of this disease, which is one of the greatest disease burdens and a leading cause of death among seniors. Selenium also helps in the prevention of the disease, which is extremely important because it is often difficult to diagnose Alzheimer’s disease in its early stages.
An international team of researchers has just completed a huge study of the possible link between maternal DNA, selenium deficiency, and preterm labor. Earlier studies have shown that women with low blood selenium have an increased risk of preterm birth and that selenium supplementation may lower that risk. A problem in that respect is that climate changes and soil depletion may increase the risk of selenium deficiencies, especially in Europe.
Lack of selenium, an essential trace element, may cause thyroid disorders, cardiovascular disease, virus infections, AIDS, infertility, neurological disturbances, and cancer. An estimated one billion people worldwide are selenium-deficient. This is mainly a result of nutrient-depleted soil, which is a real problem in places like Europe. For decades, scientists have been warning about this problem, and a lot suggests that we need more than the officially recommended intake to protect ourselves effectively against disease, according to a review article published in StatPearls.
Cataracts is one of the leading causes of vision impairment and blindness. The risk is increased by old age and diabetes. According to a new study that is published in Frontiers in Nutrition, a relatively high selenium intake can protect against the disease. The scientists mention that because of selenium’s unique antioxidant properties this nutrient protects the cells in the eye and in other places against free radical damage and oxidative stress.
Selenium is crucial for your thyroid function, immune system, cardiovascular system, and even for preventing cancer. Fish and shellfish are among the best selenium sources, but even 200 grams of fish and shellfish five days a week won’t do the trick, according to a Danish selenium study. What makes it even more difficult to obtain optimal amounts of this nutrient is that the agricultural soil in large parts of Europe is stripped of vital nutrients like selenium. Margaret P. Rayman, one of Europe’s leading experts on selenium, says that there is a direct link between the decreasing selenium intake and the increasing rate of cancers, rheumatism, infertility, and numerous other health problems. The question is, how do we humans get enough selenium?
Supplementing with the trace element selenium may reduce a man's risk of developing prostate cancer, according to a Danish report.
Men may reduce their risk of contracting prostate cancer simply taking supplements of selenium or by eating foods that are rich in this vital trace element. A 2014 report issued by the National Food Institute, a subdivision of the Technical University of Denmark, concludes on behalf of thorough analyses of the available science that there is an inverse relation between selenium intake and the incidence of prostate cancer. The new report represents the scientific foundation for a whole new set of dietary guidelines recently issued by the Danish Veterinary and Food Administration.
We all get exposed to mercury, a neurotoxin that is found to a great extent in nature and in our environment. According to an EU report, mercury is a large economic burden to society because of the costs related to lowered IQ levels. For that reason alone, we should aim to limit our exposure to mercury and also take a closer look at how selenium protects against the harmful heavy metal – provided our selenium levels are adequately high.
Selenium is a constituent of at least 25 essential proteins (selenoproteins), including several antioxidants that protect cells against oxidative stress and disease. A team of researchers from Munich in Germany has mapped out the mechanisms, which the selenium-containing antioxidants use to protect neurons in the brain against cell death. The scientists see a whole new potential with selenium because of its ability to protect against neurological disorders and cancer. It is problematic, however, that we have widespread selenium deficiency in our part of the world. Even if you stick with the official dietary guidelines, it is very difficult to get enough selenium to saturate all the different selenoproteins.
Everybody is exposed to heavy metals and other environmental toxins. They are present in the water, the air, our diet, in cosmetics, tobacco smoke, medicine, and countless other sources. These toxins increase our risk of cancer, neurological disorders, thyroid disease, autoimmune disease, and numerous other health problems. Also, the combination of different toxins causes a “cocktail effect” that we know very little about. According to a Spanish study of mice, which is published in Science of The Total Environment, a selenium-enriched diet has a protective effect.
- and routine screening is not enough
Cancer in the colon and rectum is rather common. One in 20 Danes gets colon cancer at some point in life. Since 2014, the Danish Health Authority has recommended a screening program, offering middle-aged and older people a screening for colon cancer every other year. If the disease is discovered in its early stage, the chances of successful treatment increase. Supplementation with organic selenium yeast has been shown to lower the risk of colorectal cancer in the first place, and selenium even has a protective effect against other cancer forms, so the nutrient is an essential part of the prevention. The problem is that selenium deficiencies are so common as a result of our nutrient-depleted soil.
– and why it is vital to get the exact right amount!
All our cells contain different selenium compounds that support a number of vital functions, and which have several cancer-fighting mechanisms. As an antioxidant, selenium prevents iron from developing some of the most harmful free radicals that can damage cellular DNA and lead to uncontrolled cell division. This is why a selenium deficiency combined with excess iron is a lethal cocktail. Although iron is essential, it is vital that we do not get too much. It is also important to get plenty of selenium from food and/or supplements and in a form that the body can absorb and utilize in each and every cell in order to be properly protected against cancerous substances.
Cancer has become one of the leading causes of death, with rates going up every year. The diet plays a major role and there is a lot of focus on selenium as an anti-cancer agent – both in the form of selenium-enriched functional foods and selenium supplements. Around one billion people worldwide are believed to lack selenium. According to a review article that is published in Foods, however, taking a daily supplement of 100-200 micrograms of selenium yeast can prevent deficiency and reduce some of the most common cancers by fifty percent.
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 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.
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 of the Swedish study shows that taking these two supplements even has a notable long-term effect on cardiac function and lifespan.
- 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.
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.
– 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.
If you are vegetarian or vegan you need keen insight in order to know how to get enough protein, vitamins, minerals, fatty acids, and certain amino acids. Lack of essential nutrients can cause anemia and fatigue but may also increase your risk of serious diseases.
We all are exposed to some degree of air pollution, but a new study shows that supplements of vitamin E and omega-3 fatty acids work like a dynamic duo with a highly protective effect on cells and the cardiovascular system. This is because vitamin E is a powerful antioxidant and omega-3 fatty acids have anti-inflammatory properties.
and can antioxidants prevent it?
Overweight often leads to type-2 diabetes and the early stage of the condition known as insulin resistance. A new scientific study suggests that oxidative damage, also known as oxidative stress, sets the stage for these disturbances in the body's sugar and lipid metabolism. The doctors behind this study therefore theorize that it is possible to prevent type-2 diabetes with antioxidants that are known to counteract oxidative stress.
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.
