About Red onions sliced

Red onions are a popular variety of onion distinguished by their purplish-red skin and white to red-tinged flesh. Originating from Asia, they are now commonly used in global cuisines, particularly Mediterranean, Indian, and Mexican cooking. Red onions are low in calories, with approximately 40 calories per 100 grams, and are rich in antioxidants, vitamins, and minerals. They contain a significant amount of vitamin C, B6, and potassium, along with trace amounts of iron and magnesium.
