- and lack of nutrients is an overlooked problem
According to the statistics, far too many patients contract an infection while being hospitalized in a Danish hospital. This has enormous human and economic costs that need to be addressed. Hospital infections are not only a consequence of poor hygiene, it actually turns out that 40 percent of the patients are malnourished to some degree, which impairs their immune system and makes them an easier target for infections. Lack of vitamin C, vitamin D, selenium, zinc, and iron seem to be the big and overlooked problem.
- 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.
- 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.
- 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 That dietary advice is outdated and has done more harm than good.
Supplementing with strong antioxidants such as beta-carotene, vitamin E, selenium, and coenzyme Q10 may help patients with cystic fibrosis by reducing a number of the respiratory infections that come with the disease. This was seen in a study by researchers at the Children’s Hospital Colorado and the University of Colorado, United States.
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.
- 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.
A new study links thyroid disorders to female infertility. At the same time, it is known that selenium, an essential micronutrient, is required for normal functioning of the thyroid gland. Modern diets are depleted of selenium and the question is: Could selenium supplements be a good place to begin for infertile couples before embarking on expensive IVF therapy?
Infertility affects around one in seven couples. WHO considers it a global health problem. One of the leading causes is impaired semen quality, and Danish, Norwegian, and German men have lower sperm quality than any other male populations. Impaired sperm quality may be a result of an unhealthy lifestyle with stress, tobacco, stimulants, and hormone-disrupting compounds. On the other hand, scientists from Mexico have found that supplements of zinc, selenium, Q10, and omega-3 have an effect on the number of sperm cells and their quality. Other studies show that zinc and selenium protect sperm cells and are important for testosterone levels.
It appears so. Iodine is an essential trace element that is vital for metabolism and estrogen balance. Iodine also helps the body get rid of environmental toxins. In fact, exposure to these toxins increases our need for iodine, and many experts believe that the official recommendations for iodine are too low.
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.
Having healthy-looking hair means a lot to most people. Hair that splits at the ends, hair loss, and other hair problems may be caused by stress, hormone changes, and numerous other factors. In this article, we will take a closer look at the diet and its impact on hair health, and we will look at available studies of protein, iron, zinc, selenium, silica, B vitamins, vitamin D and vitamin A. The fact is, we need plenty of these nutrients in a form that the body can absorb and utilize. On the other hand, getting too much can do more harm than good, according to an article in Dermatology Practical & Conceptual, in which the author has analyzed the available research.
Lack of selenium increases the risk of impaired fertility and complications in connection with pregnancy and birth. Because selenium deficiencies are rather common, both men and women should ideally make sure that they get enough of this essential trace element that is involved in various functions - right from conception to delivery.
Hashimoto’s thyroiditis is the most common underlying cause of hypothyroidism. It is characterized by extreme fatigue, weight gain, and a number of other symptoms. Hashimoto’s is an autoimmune condition where antibodies attack the thyroid gland. Many people who get treatment for their disease don’t improve, on the contrary. According to a meta-analysis published in Medicine, however, selenium supplementation appears to be able to reduce the autoimmune reactions and the body’s production of the different antibodies. Selenium helps control the thyroid function but also serves as an antioxidant that protects the thyroid gland against oxidative stress.
- 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.
- plus thyroid disorders, poisoning, and a lot more
Iodine is the only mineral, which is compulsorily added to foods because it is can prevent goiter. Studies show that iodine also plays a role in the metabolism, the energy levels, estrogen balance and even helps prevent breast cancer. What is more, iodine can help the body get rid of environmental toxins such as fluoride compounds. Many experts believe that the official iodine recommendations are too low, and it is important to make a note of the fact that refined table salt often contains anti-caking agents like aluminum, and that sea salt is not enriched with iodine.
Iodine's ability to protect against breast cancer has been demonstrated in animal studies. Furthermore, epidemiological studies suggest that consuming more dietary iodine lowers the risk of the dreaded disease, which represents 25% of all cancers in women.
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.
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.
Millions of people take painkillers such as Panadol or Calpol that contain paracetamol, and an estimated one billion people or so lack selenium due to nutrient-depleted farmland. This is an unfortunate cocktail because being deficient of selenium increases the risk of using paracetamol, so even the recommended dosage burdens the liver to such an extent that it causes toxicity and increase the risk of side effects. This was demonstrated in a collaborative study carried out by Bath University in England and Southwest University in China.
Earlier studies have found a link between low selenium and overweight, but only few and limited studies have investigated this connection in children. Therefore, Chinese researchers wanted to take a closer look, and selenium levels in nail clippings give a rather accurate picture of the body’s general selenium status. Selenium deficiency is common in many parts of the world, including parts of China and Europe.
- 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.
- with four key nutrients
Your birth attest reveals your actual age but your biological age gives a more accurate picture of your health and life expectancy. Our biological age and cardiovascular health are closely connected, with atherosclerosis and arterial stiffness representing a progressive process that eventually leads to the majority of deaths. Nonetheless, you can do a lot yourself by making sure to get sufficient amounts the nutrients that are most vital for good cardiovascular health. In this article, we will look closer at some current studies of vitamin K2, Q10, selenium, and omega-3, all of which are essential nutrients that prevent, each in their own way, atherosclerosis, arterial stiffness, and premature death as a result of having high heart age.
- and there is focus on nutrient deficiencies
The whole climate debate has made it increasingly popular to become a vegetarian or a vegan. However, according to a new and comprehensive study from Oxford, this choice of lifestyle may have grave health consequences and can increase your risk of apoplexy, also known as stroke, cerebral hemorrhage or cerebral thrombosis. The study is published in British Medical Journal. Earlier studies also give rise to concern, as a plant-based diet often lacks protein, vitamin D, vitamin B12, iodine, selenium, iron, and omega-3 fatty acids, and that can increase the risk of thyroid disorders, neurological disorders, infections, chronic inflammation, impaired fertility, growth disturbances in children etc. Some of these deficiencies are insidious and difficult to link to the diet.
- 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.
During pregnancy, the unborn child needs different nutrients for proper development of its brain and nervous system. Even if the mother eats a balanced diet, it can be difficult to get enough selenium for a number of reasons. In a new Italian animal study that is published in Nutrients, scientists have looked closer at selenium’s role during pregnancy and lactation. They observed that even minor selenium deficiencies can have a negative effect on the offspring’s brain development and behavior. This study supports earlier human studies showing how vital it is for the mother to get plenty of selenium during pregnancy and breastfeeding.
Most people thrive on the idea of staying physically active throughout life, but as we grow older, our skeletal muscle slowly vanishes and our figure changes. This is known as sarcopenia and is one of the main reasons why older people become more fragile and perhaps even disabled. Exercise and diet play a major role, and it seems that the official dietary guidelines are not optimal and should focus more on increased intake of protein as well as lysine, vitamin D, and omega-3 according to a new Canadian study. Earlier research shows that magnesium, selenium, and Q10 are also important for muscle mass and strength.
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.
A previous study has demonstrated that daily supplementation with coenzyme Q10 and selenium increases heart muscle strength in seniors and reduces their cardiovascular mortality by over 50 percent. Now, a team of Swedish and Norwegian scientists has found that these two nutrients are also able to slow down the age-related shortening of cellular telomeres, which are attached to the ends of all DNA strands. You can compare telomeres to the small aglets that prevent our shoelaces from fraying and tangling. Like aglets, telomeres protect the DNA strands, but they are exposed to attrition and eventually wear out. The more worn our telomeres become, the more exposed the cellular DNA becomes, until it reaches the point where the cell finally perishes. Q10 and selenium appear to preserve telomere length, thereby keeping us in good health for longer time.
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.
Colorectal cancer is one of the most common cancer types. Although the diet is of huge importance, the understanding of minerals and their interactions and preventative effect is limited. Earlier studies have shown that calcium and selenium have protective roles. It also looks as if having more selenium in the blood can improve the effect of calcium. This was demonstrated in a new Polish study that is published in BMC Nutrition. The scientists point out that there is widespread selenium deficiency in Europe and that supplementation may be needed.
The way in which selenium and iodine interact is determining for the thyroid gland and the metabolism. A deficiency of one or both nutrients coupled with exposure to environmental toxins may have grave consequences and contribute to some of the most commonly occurring metabolic disorders.
The rate of metabolic disorders has increased exponentially on a global scale. Most of these disorders fly under the radar so to speak and remain undiagnosed. At the same time, up to 20 per percent of those people who are diagnosed and get medical treatment for their condition do not improve. We need to focus much more on selenium and iodine - partly because these essential trace elements work as a team in regulating thyroid hormones, and partly because modern diets and exposure to environmental toxins increase the risk for deficiencies and imbalances.
How iodine and selenium regulate thyroid hormones
The thyroid gland that is located on the front side of the throat produces two different thyroid hormones. T4 is the passive hormone that contains four iodine atoms, while T3, the active hormone, contains three iodine atoms. In order to activate the metabolism in the different tissues and cells of the body, selenium-containing enzymes remove an iodine atom from the T4 hormone, thereby converting it to active T3. This conversion is regulated in accordance with the body's specific needs. As expected, it requires sufficient amounts of selenium and iodine for this to take place, but is there enough or do we have a shortage?
- 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.
Although cancer treatments have improved drastically, science has still not managed to break the curve. On the contrary. A growing number of people contract cancer, and that is why we should focus more on the trace element, selenium, which possesses several mechanisms against cancer. However, it requires that we get enough selenium and that is in a form that the body is able to utilize optimally.
According to statistics from the Nordic database NORDCAN, the number of cancers will increase by more than 50% in the years to come. Cancer is currently the leading cause of death among people younger than 65 years of age. Many of those who follow the official healthy lifestyle recommendations by maintaining their ideal weight, limiting their alcohol intake, exercising regularly, and choosing not to smoke, are also affected by cancer. Although there are many things that cause cancer, it looks as if too little selenium is an important yet underestimated factor.
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.
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.
Low selenium status increases a man's risk of prostate cancer and Danish men are particularly susceptible, according to a study published in British Journal of Nutrition. Earlier studies have shown that supplementation with selenium prevents prostate cancer, and selenium yeast has been shown to have the best 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.
Involuntary childlessness has become increasingly common. Many women find themselves in a race against time, and their biological clock keeps ticking louder and louder. Fertility therapies, miscarriages, preeclampsia, and other complications during pregnancy contribute to the physical and emotional burden. In a new Australian study that is published in Nutrients, the authors write about selenium and zinc and how these nutrients play an important role in fertility and a healthy pregnancy. They also address the problems with widespread selenium deficiency and point out that environmental toxins like mercury deplete levels of vital selenium-containing proteins in the body. The scientists point to supplements for fighting deficiencies, just like folic acid and iron are routinely recommended to pregnant women. It pays off to choose selenium yeast with multiple organic selenium compounds and organic zinc to help improve the bioavailability and utilization of the nutrients.
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 seleniumas 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.
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.
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.
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.
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.
The kidneys cleanse our blood. Well-functioning kidneys are vital for the circulatory system and good health in general. Normal functioning of cells, including kidney cells, hinges on a host of different selenium-containing proteins and coenzyme Q10. Studies show that older people in many parts of the world, Europe included, have deficiencies of both substances. Therefore, a team of Swedish scientists conducted a study where they looked at selenium status and kidney function in a group of seniors. They gave selenium yeast and coenzyme Q10 or placebo to the participants for a period of four years. The results showed that the supplemented group as compared with the placebo group had improved kidney function according to several parameters. The positive effect on cellular energy metabolism, inflammation, and oxidative stress was attributed to the two supplements. The study is published in the science journal Nutrients.
A woman’s estrogen balance is of vital importance to her fertility, mucosa, mood, libido, bones, cancer preventions, and many other things. There are also many myths about estrogen, which is merely a common term for the three types of estrogen – estradiol, estrone, and estriol – that have widely different functions. Like progesterone, stress hormones, and testosterone, estrogen belongs to the group of steroid hormones, where one hormone is built from another with help from enzymes. These enzymes depend on various nutrients such as iodine, vitamin D, magnesium, and selenium. If we lack these nutrients it may increase our risk of hormone imbalances, hot flushes, dry mucosa, bladder problems, and breast cancer. You can also read more about hormone-disrupting substances, hormone therapy, and bioidentical hormones.
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.
The global differences in prostate cancer rates reveal that this type of cancer is associated with lifestyle. For example, Inuits have a very low rate of prostate cancer, which is attributed to their high intake of omega-3 fatty acids from seal, salmon, and other maritime sources. It turns out that the content of the omega-3 fatty acid EPA in prostate cells is a determining factor for how and if the disease develops, according to a new study that is published in Nutrients. Selenium also has anti-cancer properties, especially with relation to prostate cancer, and there are other dietary measures that can make a difference.
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.
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.
