For example, selenium-enriched tea, selenium-enriched rice, selenium-enriched water, etc., many healthy people will be supplemented by selenium to prevent cancer, this practice is really desirable? Can selenium really fight cancer?

I. Can selenium really kill cancer cells?

A study published in Nature Metabolism by researchers at the University of Massachusetts Medical School found that the metabolic enzyme SEPHS2 in selenocysteine organisms has a selenium detoxification role, and this detoxification role is necessary for cancer survival. By inhibiting SEPHS2, it can serve to disrupt selenium utilization in tumor tissue, which can ultimately allow cancer cells to die from selenium toxicity.

So does this make selenium supplementation a good idea to prevent and fight cancer?

The answer is no! It is undeniable that the body will get sick when there is a large lack of selenium in the body, which is most typical of Keshan disease. But that doesn't mean we can blindly take selenium supplements. A pooled study involving several selenium supplements and cancer prevention, Selenium and Cancer Prevention, states that no evidence was found to support the idea that selenium supplementation can help prevent cancer in humans.

For modern people, food intake itself is relatively abundant, and it is entirely possible to obtain the selenium needed by the body through food; most people are not deficient in selenium at all, and there is no need for deliberate supplementation.

The WHO recommends a maximum daily intake of 400 μg of selenium for adults. Although selenium is an essential element of the human body, it is not a good idea to consume as much as you can, as long-term high intake of selenium may induce selenium toxicity and bring about the loss of nails and hair, and damage to the liver and other hazards.

The vitamin D deficiency rate of elderly people over the age of 60 years can reach 22.2%, vitamin D can be involved in the body's absorption and utilization of calcium, the lack of vitamin D can easily lead to osteoporosis, rickets and so on. It is recommended that the elderly over 65 years old maintain a daily intake of 15μg, daily sunshine, eat more egg yolks, milk, mushrooms and other foods to supplement.
