The green leaves and immature and mature bulbs are eaten raw or used in preparation of vegetables. Onions are used in soups, sauces and for seasoning foods. The small bulbs are pickled in vinegar. Recent research has suggested that onions in the diet may play a part in preventing heat stroke and other ailments. Onion bulb is rich in phosphorus, calcium and carbohydrates.
