I have friends who drink alcohol around me, and I often see their gum bleeding, oral ulcer, bad breath, epithelial keratosis, greasy and dry skin, hair loss, enteritis, diarrhea and so on. The reason for these phenomena is the lack of vitamins. Alcohol will affect the absorption and metabolism of folic acid and other vitamins, which will further expel folic acid stored in the body and reduce the absorption of folic acid in the intestine. People who drink alcohol for a long time need to supplement folic acid in moderation, and it is recommended to take folic acid under the guidance of a doctor. In addition, it is best for women who plan to get pregnant to stay away from alcohol, otherwise it will affect the development of fetal brain, and there may be mental retardation after birth.
