Bonappetit
Much like garlic, onions tend to be the basis of any tasty meal, since they tend to be used as the basic flavoring in a number of savory dishes. Aside from their strong smell, onions are rich in flavonoids, most especially quercetin, which is a strong antioxidant that protects against a number of cancers, as well as lessen the chances of heart disease. They also have a substance called prostaglandin, which works to lessen high blood pressure and reduce blood viscosity, which slows down the advancement of kidney disease.
