Widespread selenium deficiency increases your risk of virus infections, thyroid disorders, impaired fertility, neurological disorders, cancer, and AIDS
Selenium is an essential trace element that is important for the immune defense, metabolism, fertility, nervous system, and cancer prevention. An estimated one billion people worldwide are believed to be selenium-deficient. Because European agricultural soil is low in selenium, we Europeans are more exposed than others. It appears that selenium deficiencies increase our risk of many acute, chronic, and life-threatening diseases, and the official recommendations for daily intake are too low, according to a new article about selenium deficiency, which is published in the scientific American database NCBI (National Center for Biotechnology Information).



Some people who take cholesterol-lowering statins may experience depression due to the fact that the medicine lowers levels of Q10, a substance that is vital for cellular energy production. Supplements of Q10 taken along with the medicine may prevent this side effect.
Medical science has traditionally used the term "chronic heart failure" about patients who had poor heart function, low exercise tolerance, chest pain and shortness of breath. Now, this condition is also known as the energy-starved heart. If the heart muscle is no longer able to produce sufficient amounts of energy to carry out its basic functions, it has serious implications for patient's quality of life.
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.
Perhaps so. More and more studies reveal that it helps to take large quantities of Q10 and a vitamin B3 derivate. Q10 and vitamin B3 are both essential for the body’s energy turnover, which takes place inside the mitochondria of the cells. A more recent study shows that taking supplements of the mentioned nutrients can also have a positive effect on the heart, which is the body’s central motor.
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.
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.
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.
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.
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.
Approximately one in seven couple is childless. Although there can be many underlying causes, poor sperm quality is an increasing problem. It may be caused by a lack of certain nutrients and exposure to different environmental factors, but, fortunately, it possible to improve sperm quality and increase the chances of conception by means of relevant dietary adjustments and the use of specific supplements. New research shows that epigenetic factors (factors that affect the environment of the sperm cell) determine sperm health and are therefore crucial for activating the genes of the sperm cell so the fetus can develop.
