Onions are one of the most widely used vegetables in kitchens around the world. Beyond adding flavor to meals, onions contain several nutrients and natural plant compounds that contribute to overall health. They belong to the Allium family, which also includes garlic, leeks, and shallots.
Including onions as part of a balanced diet can help provide vitamins, minerals, and antioxidants that support the body’s normal functions.
