Onions may have anti-cancer properties: Several studies have shown that onions, particularly red onions, may have anti-cancer properties due to their high levels of quercetin and other flavonoids. These compounds may help to inhibit the growth and spread of cancer cells, particularly in the colon, breast, and prostate.

Some research has also suggested that the compounds in onions may help to reduce the risk of osteoporosis, a condition that causes bones to become weak and brittle.

  5. Onions may help to improve heart health: As mentioned previously, onions are a good source of quercetin, a compound that has been shown to reduce the risk of heart disease. They are also a good source of fiber, which can help to lower cholesterol levels and reduce the risk of heart attack and stroke.
