What are the functions and indications of selenium

Now everyone knows that they need to maintain their health, but they are not so clear about some nutritional elements, so people will have a lot of misunderstandings, which is not so good for their own bodies. Even the main functions and indications of substances such as selenium are not very clear. In fact, this element is very good, because it can play a good anti-cancer and cancer prevention effect on the human body. If this element is lacking, it will make people prone to cancer.

Nutritional significance

effect

①. Selenium has anti-cancer effects. People who are deficient in selenium are prone to liver cancer, lung cancer, stomach cancer, esophageal cancer, kidney cancer, prostate cancer, bladder cancer, cervical cancer, leukemia, etc.

②. Selenium has antioxidant effects. Selenium is the best anti-aging substance. If the human body lacks selenium, it will "no longer be young" and will lead to premature aging.

③. Selenium can enhance human immunity. Selenium deficiency reduces the body's immune system.

④. Selenium has the effect of antagonizing harmful heavy metals. Selenium deficiency can easily lead to symptoms of heavy metal poisoning such as lead, arsenic, and cadmium.

⑤. Selenium can regulate the absorption and utilization of vitamin A, vitamin C, vitamin E, and vitamin K. Selenium deficiency can cause myopia, cataracts, retinopathy, fundus disease, age-related macular degeneration and other diseases.

⑥. Selenium has the function of regulating protein synthesis. Selenium deficiency can cause protein-energy deficiency malnutrition, chromosome damage, etc.

⑦. Selenium can enhance reproductive function. Selenium deficiency can lead to ejaculation obstruction, low sperm motility, deformity, reduced conception rate, and increased incidence of metritis.

And so on symptoms.

Selenium is an essential component of peroxidase in seminal plasma. When the selenium content in semen decreases, the activity of this enzyme decreases and cannot inhibit the peroxidation reaction of sperm cell membrane, causing sperm damage, an increase in dead sperm and a decrease in vitality.

⑧. Selenium is an important component of muscle function. Selenium deficiency can cause skeletal muscle atrophy and gray-white stripes, myocardial damage, changes in myocardial cell density, increased lipids, and calcium deposition, leading to the occurrence of diseases.

Therefore, men need to supplement selenium more because most of the selenium supplied to the body is concentrated in the reproductive organs and can be excreted from the body along with semen. In particular, residents living in highly polluted areas and selenium-deficient areas need to supplement selenium.

Since there is no organ in the human body that can store selenium for a long time, the body should continuously obtain sufficient amounts of selenium from the diet. The balance of selenium concentration plays an important protective and promoting role in the physiological functions of many organs and tissues.

When selenium is deficient, it can easily lead to a decline in the body's immune system. More than 40 diseases that threaten human health and life are related to selenium deficiency in the human body, such as cancer, cardiovascular disease, liver disease, cataracts, pancreatic disease, diabetes, reproductive system diseases and other symptoms.

Normally, the total daily requirement for each person is that Chinese adults can obtain health benefits by supplementing selenium with more than 25 micrograms from food every day; selenium-deficient adults can obtain selenium with more than 50 micrograms or 75 micrograms from food every day. Since 72% of China's soil is selenium-deficient, the selenium content of natural foods, such as wheat, rice, corn and other cereal crops that are the main food crops, is less than 40 μg/kg. The daily selenium intake of Chinese people is lower than the minimum intake of 50 μg recommended by the World Health Organization. The daily selenium intake is only 30~45 μg, which is lower than that of Japan, Canada, the United States and other countries. Selenium-rich rice, 100 micrograms (selenium-rich corn flour), animal offal, fish, seafood, mushrooms, eggs, garlic, ginkgo, etc. are all high in selenium. People who are selenium-deficient can increase their intake of these foods appropriately.
