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. 2. Nutritional value of onionsOnions are originally produced in Central Asia and West Asia, but because of their high nutritional value, onions are grown in all parts of my country, both north and south. Onions are rich in nutrients such as carotene, vitamin C, selenium, zinc and fiber. They also contain two special nutrients, quercetin and prostaglandin A. It helps prevent cancer, maintain human cardiovascular health, stimulate appetite, promote digestion, kill bacteria and prevent colds. Its effects can be said to be very wide. But because its smell is too pungent, people always love and hate it. |
