What foods are unpalatable, but they are good helpers for health?
Raw onions are very spicy, but many foreigners eat them raw. Why? Because onions have bactericidal effect, and the bactericidal effect of raw food is more obvious. There is also an allyl disulfide and a small amount of sulfur-containing amino acids in onion, which can not only sterilize but also reduce blood fat, dilate blood vessels, remove garbage from blood vessels and reduce cholesterol content in blood.
