Onions

The onion family, including garlic and leeks, are good detoxifiers and are also antiseptic and antibacterial. The sulphur compounds they contain are also linked with protection against strokes, high blood pressure, heart disease and cancers. Just 1g of onion a day is enough to help strengthen the bones. Onions are rich in flavonoids and potassium, which can reduce blood pressure and keep the arteries healthy, and the onion family may also help to keep blood sugar levels even by regulating insulin production.
