Health Benefits Of Eating Onions

1. Nutrients-Dense

Low in calories, onions are high in minerals and vitamins. One medium onion only weighs in at 44 calories but is particularly rich in vitamin C, which helps regulate immune health, tissue repair, iron absorption and collagen production. They are also high in B vitamins, which plays a key role in metabolism and nerve function. Also, they are a good source of potassium, a mineral that people lack most.
