sihai.com: as we all know, raisin is a kind of delicious fruit and also an imported fruit. Can we eat it? Let's learn about the efficacy and function of the raisin skin?
There are rich anthocyanins in the skin of the raisins. The darker the skin color, the more anthocyanins it contains. Anthocyanin has the functions of strong anti-oxidation, anti mutation, reducing liver dysfunction and protecting cardiovascular system, so many people, especially women, insist on eating raisins with skin for its anti-oxidation and anti-aging effects. There are not only a lot of anthocyanins, but also a lot of tannins in the leather. Tannic acid is also called tannic acid. The bitter and astringent taste of raisin leather is the 'credit' of tannic acid, because tannic acid can combine with protein to form a kind of massive and indigestible tannic protein, which leads to constipation.
As a result, experts in China's Web eating industry have warned that the role of any food or any nutrient should not be magnified. Anthocyanins do have antioxidant effects, but it doesn't mean that the more you eat, the better; tannins do cause constipation, but it doesn't mean you can't eat them. For example, she said, apples also contain tannic acid, but apples can promote defecation, and anthocyanins are not only found in the skin of raisins, but also in the flesh and many foods. Although there is a lot of tannic acid in the skin of a raisin, it doesn't mean that eating a raisin with the skin will cause constipation. Therefore, whether or not to eat the skin of the raisin can be completely selected from the perspective of personal preferences -- if you are used to eating, you can eat it without physical discomfort; otherwise, if you do not like it and are not willing to eat it, there is no need to force yourself.
