Selenium is taken into to body in foods and water. While people use it for medicine, Selenium is a mineral. Diet is where most Selenium comes from. The health benefits of selenium come from crab, poultry, fish, or wheat. The Selenium in foods depends on where the food is raised or grown. The selenium in the soil also varies. It means that food that is grown in different regions also different Selenium levels.
Selenium is mostly used to cure heart diseases. It can also prevent prostate cancer, stomach cancer, skin cancer, and lung cancer. For some people, they also use Selenium for osteoarthritis, under-active thyroid, rheumatoid arthritis. They also use Selenium for macular degeneration, infertility, cataracts, pap smears, chronic fatigue syndrome, and arsenic poisoning.
In addition, Selenium can also prevent serious complications or death from critical illness. It can also prevent bird flu. In addition, it reduces the side effects of cancer chemotherapy.
What is Selenium?
Selenium is an essential trace mineral, which is important for a lot of bodily processes. This includes fertility for both men and women, healthy immune system, as well as the cognitive function. Furthermore, selenium contributes to the DNA synthesis and the thyroid hormone metabolism. Moreover, it helps in protecting against infection and oxidative damage.
Furthermore, selenium is present in the human tissue, but mostly in the skeletal muscle. Additionally, the dietary sources may vary as well –including meats, seafood, and Brazil nuts. Moreover, the selenium content in foods depends on the concentration of selenium in the water and soil where the farmers grew them.
Why should you take Selenium?
Selenium is popular because of its antioxidant properties that protect the cells from damage and prevent cancer. There is evidence that selenium supplements can lower the possibility of prostate cancer. According to studies, men took 200 micrograms of Selenium daily to determine if it can aid in prostate cancer prevention.
Health Benefits of Selenium
Below are some of the health benefits of selenium:
Lack of Selenium. Consuming Selenium by the mouth is effective to prevent selenium deficiency.
Autoimmune Thyroiditis. According to research, taking 200 mcg of selenium daily together with thyroid hormone can decrease the antibodies in the body that can contribute to this condition. Selenium can also improve the mood and general feelings of well-being of the individual with this condition.
Cholesterol Levels. According to research, taking 200 mcg of a specific selenium supplement such as SelenoPrecise or Pharma Nord daily for 6 months can reduce cholesterol levels in the body.
Ineffective Health Benefits of Selenium
Asthma. According to research, there is no link between asthma and the blood levels of Selenium. In addition, the researchers suggest that taking 100 mcg of Selenium daily does not improve quality of life. Taking Selenium for 8 months does not improve asthma symptoms, lung function, or people with asthma.
Diabetes. According to research, patients with low selenium levels have a higher risk of developing type 2 diabetes. But, other research suggests that patients who have high levels of selenium also have an increased risk of type 2 diabetes. In addition, according to studies, patients who take 200 mcg of selenium daily for about 7 years increased the risk of developing type 2 diabetes.
Eczema. According to research, consuming yeast that is enriched with 600 mcg of selenium daily does not improve the severity of eczema. Even if you take it for 3 months, alone or together with vitamin E it is not effective.
Heart Disease. There is research that says consuming Selenium does not lower the risk of heart disease. For patients who already have heart disease, consuming 100 mcg of selenium does not prevent the heart disease from becoming worse. Even if you consume it together with vitamin C, vitamin E, and beta-carotene. In addition, taking 200 mcg of Selenium daily for 8 years does not lower the risk of developing heart disease.
Kidney damage or hearing loss caused by cisplatin. According to research, consuming selenium does not prevent kidney damage and hearing loss in patients being treated with the chemotherapy drug cisplatin. Even if you consume it with vitamins E and C.
Critical illness such as head injury, trauma, burns. Giving 500-1000 mcg of selenium intravenously or 300 mg of selenium by mouth daily to critically ill patients does not reduce the risk of infection or death.
Insufficient Evidence of Health Benefits of Selenium
Arsenic poisoning. For people expose in environments with arsenic, consuming yeast that is rich in selenium decrease the arsenic levels that the body absorbs.
Cancer. According to research, consuming 400 mcg of selenium daily does not reduce the risk of developing cancer. Even if you take it for 2 years. Or consuming 100 mcg of selenium along with vitamin C, zinc, beta-carotene and vitamin E, daily does not reduce the risk of developing cancer. Even if you consume it for 7 years.
On the other hand, there is research that suggests consuming selenium can lower the risk of cancer-related death.
In addition, according to research selenium can reduce the risk of cancer in men, while selenium with allitridum can lower the risk of cancer in women.
Rectal and Colon cancer. The evidence is conflicting about the effects of selenium on rectal and colon cancer.
According to studies, low selenium blood levels are not linked with the risk of developing rectal and colon cancer.
On the other hand, there is research that suggests, consuming selenium alone or with antioxidants can reduce the risks of rectal and colon cancer. But, there are researchers that suggest selenium has no effect.
