Actually, for selenium, I think. I think we are still strangers. Maybe we only know some trace elements such as calcium, zinc and iron that the human body needs, but we have never heard of selenium. In fact, selenium is still very important to the human body, although it may only account for one tenth of the human body. But it can effectively kill cancer cells and delay aging. Therefore, a very intuitive function of solar elements is to delay aging, kill cancer cells and resist oxidation.

However, this concept is a bit over-hyped, that is, people nowadays are generally deceived by some gimmicks of merchants. In fact, there is no need to supplement the so-called selenium objectively, because in normal life, there is selenium in the food we eat more or less. If you deliberately eat it, it actually has no effect. For example, the selenium-enriched orange merchants posted on the Internet say that selenium can be supplemented, but we should know that selenium-enriched oranges can only be supplemented by eating about ten kilograms a day.

So for your question, I think selenium-enriched oranges are selenium-supplemented, but I don't need to know, because selenium supplementation is really minimal. Usually pay more attention to rest, eat something properly, don't be picky about food, you won't be short of selenium, and there is no need to worry. Moreover, the ancients did not deliberately eat anything.

They are still alive and well, so we don't need to be fooled by these pseudosciences. Although selenium is an essential element for human body, we don't need to care too much, because we usually eat enough, so eat more. Selenium-enriched foods pay for IQ.

Therefore, I personally think that selenium-enriched oranges can supplement selenium, but the supplement is really minimal, so there is no need to eat them.
