Onions are a flavorful superfood packed with health benefits. Eating them daily can boost heart health by lowering blood pressure and cholesterol thanks to quercetin and sulfur compounds. Their antibacterial, antiviral, and vitamin C content strengthen the immune system, while fiber and prebiotics support digestion and gut health. Onions’ antioxidants reduce inflammation and ease pain, and their calcium, magnesium, and sulfur promote strong bones and collagen production. Adding onions to meals daily is an easy, affordable way to enhance overall wellness and maintain a healthy, vibrant lifestyle.
