What are the benefits of eating onions? The nutritional value of onions

1. What are the benefits of eating onions?

Antibacterial and anti-cold: Onions contain phytoncide such as allicin. These phytoncides have strong bactericidal ability and can effectively resist influenza viruses and prevent colds.

Promote digestion: Onions contain allicin, which has a strong aroma and releases a pungent smell when processed. This smell will make people want to cry, but it will also stimulate the body's gastric acid secretion and promote gastrointestinal motility, thereby promoting digestion and increasing appetite.

Cancer prevention: Onion’s cancer prevention effect comes from the quercetin and selenium it is rich in. Selenium can inhibit the growth and division of human cancer cells, while quercetin can reduce the activity of cancer cells.

Lower blood pressure: Prostaglandin A unique to onions is a natural blood thinner. It can dilate human blood vessels and reduce the blood concentration inside them, thereby increasing coronary blood flow and reducing peripheral blood flow. In addition, it can counteract pressor substances such as catecholamines in the human body, promote the excretion of sodium salts, and lower blood pressure.
