The efficacy and function of onions, what should not be eaten with onions

1. The efficacy and function of onion

Prevent cancer: Onions are rich in selenium and quercetin. The former is an antioxidant that can stimulate the body's immune response, thereby inhibiting the division and growth of cancer cells in the human body. The latter can inhibit the activity of cancer cells and prevent them from continuing to grow.

Maintain cardiovascular health: Onion is one of the few vegetables that contains prostaglandin A. This prostaglandin A can dilate human blood vessels and reduce blood viscosity, thereby lowering blood pressure and increasing blood flow in the coronary arteries, preventing the formation of blood clots. In addition, onions are rich in quercetin, which helps prevent the oxidation of low-density lipoprotein.

Stimulate appetite: Onions contain allicin, which has a pungent smell. However, this smell can stimulate the secretion of gastric acid, promote gastrointestinal motility, increase people's appetite, and play an appetizing role.

Sterilization: Onions contain allicin and other phytoncide, which have strong bactericidal ability, can resist influenza virus disease and prevent colds.
