Can selenium supplement prevent cancer and resist aging? Is it necessary to eat selenium-enriched food in daily life? With the improvement of health literacy of Chinese residents, the word "selenium" has appeared frequently in various media and networks in recent years. In major supermarkets and markets, there are also various selenium-enriched foods, such as selenium-enriched rice, selenium-enriched eggs and selenium-enriched vegetables. According to the media, selenium is a very important trace element in human body, and selenium supplementation can prevent many diseases. Merchants even promote that selenium can prevent cancer and resist aging.

Can selenium prevent cancer and resist aging?

Selenium is very important to the body and can prevent some diseases. In terms of anti-cancer and anti-aging, everyone must look at it objectively. In 20 14, a biologist carried out a search strategy for the actual effect of selenium supplementation in preventing cancer in 55 innovative laboratory experiments and 8 randomized controlled intervention experiments with selenium supply of 200-500 ug/d. The results showed that selenium supplementation could not reduce the incidence or mortality of cancer. Please stop blindly following the trend and firmly believe that selenium can prevent cancer and resist aging.

Do you have to eat rich dried ingredients in your daily life?

The composition of plate structure selenium is only 100 million, which is one of the most obvious countries in the world in China as a whole. The packaging and planning of these health care products and selenium-enriched foods are mostly for this reason.

But think about it. If the soil in our country is short of selenium, will our body be short of selenium? Selenium is so critical to everyone, isn't the more the better?

First of all, selenium, as a nutrient element, is not too much for everyone's body. Only 19ug per day can prevent the occurrence of selenium deficiency-related diseases, and it is strongly recommended that the daily supply of selenium in China is 50ug. Secondly, the more selenium, the better. According to the current data, the suitable range of selenium in blood night is 80- 120ug/L, below or above this range, it may cause a series of diseases. If the concentration of selenium in blood unexpectedly reaches 1000ug/L, there will be a potential risk of poisoning.

Whether you must eat rich dried ingredients in your daily life depends on whether your body is deficient in selenium. In our daily life, the key to selenium intake comes from cereals, beans, meat, seafood, eggs and dairy products. For most people, as long as they have a normal diet, they will not be short of selenium and do not need extra selenium supplementation. In some remote and poor mountainous areas in China, it is very likely that selenium deficiency will occur because of unreasonable diet, and it is really necessary to supplement it, but this is only a rare case.
