Selenium is a trace mineral found in varying amounts in the soil. Regional variations are reflected in the amount of selenium in plants. This amount is reflected in the selenium content of animal and plant products for human consumption and therefore have a major impact on the amount of selenium in human diets. This has caused a health problem in many parts of the world.
Low concentration of selenium in the blood is associated with increased risk of spontaneous abortion, male fertility, increased risk of cancer and higher rates of cancer mortality. An inverse relationship between the concentration of blood selenium and cardiovascular disease has also been described.
Biological role of selenium is listed below.
Anti-oxidation: neutralize the toxic products of oxygen metabolism or from environmental or normal metabolic processes in the body.
Metabolism Thyroid
Immune function
Fertility
Poor growth, inefficiency
Muscle myopathy
Selenium Reduces Risk of Cancer
Selenium supplements may help protect against lung cancer, colon, rectum and prostate. Selenium supplementation of the diet significantly decreased human cancer mortality.
Selenium increases the chances of survival AIDS
Selenium deficiency decreases the immune response and so makes them more susceptible to disease. A selenium deficiency has a profound effect on survival in HIV – infected men and women. HIV-1 infected patients with selenium deficiency are 20 times more likely to die from HIV related causes than those with adequate selenium levels.
Selenium reduces the risk of strokes and heart attacks
Antioxidant properties of selenium against may have a role in primary and secondary prevention of heart disease. Selenium is necessary for the formation of a group of substances called prostaglandins that provide protection against high blood pressure. These prostaglandins also help prevent blood clotting abnormal arteries that can lead to stroke or heart attack.
Selenium helps maintain a healthy level of blood sugar
Selenium is reported to mimic the action of insulin. In studies, Selenium has been shown to mediate a series of actions such as insulin, such as stimulating glucose uptake and regulation of metabolic processes, including glycolysis, gluconeogenesis, fatty acid synthesis and the pentose phosphate pathway. Selenium is also reported to play a role in reducing oxidative stress associated with diabetes, delaying the progression of secondary complications of diabetes such as neuropathy, retinopathy and cataracts.
Selenium Reduces arthritis pain
Low selenium status has been associated with the incidence arthritis. Preliminary studies indicate the beneficial role of selenium as a debugger free radicals that can slow the progression of arthritis.
