Black beans are rich in vitamins, among which E and B vitamins are the highest, and the content of vitamin E is 5~7 times higher than that of meat.
As we all know, vitamin E is a very important substance to keep young and healthy. Although the ancients in China didn't know that black beans contained more vitamin E, they knew from practice that it was a beauty food. For example, the ancient Pharmacopoeia records that black beans can beautify, improve eyesight, blacken hair and make skin white and tender.
