Elderly people should take more B vitamins

They are one of the six major nutrients in the human body (sugar, fat, protein, salts, vitamins and water).

Some participate in the metabolism of sugar, fat, and protein, some participate in redox reactions in the body, and some affect the development and maturity of cells. In short, they are not only necessary substances to promote metabolism and energy conversion in the human body, but also effective drugs for treating vitamin deficiency. clinical Commonly used B vitamins include

　　Supplementary dose: The elderly need to supplement more than 1 microgram per day.

　　Food source: mainly provided by animal foods such as meat, fish, chicken, and milk. It can also be synthesized in small amounts in the human intestine.

　　Vitamin Bc (folic acid)　Combined with vitamin B12 to prevent and treat pernicious anemia, megaloblastic anemia, and atrophic gastritis. The latest research shows that elderly people whose diet is rich in folic acid can reduce the risk of Alzheimer's disease by 60%.
