Sweet onions are aromatic root vegetables available in various varieties with a flavor characteristic of garlic or chives. They are high in vitamin C, chromium, folate, and fiber, which are nutrients that many people do not get enough of regularly. The sweet onion is less acidic than its relatives, which results in a mild and sweet flavor. Due to its milder flavor, the sweet onion is an excellent nutrient-dense vegetable to include in the diets of both adults and children.
Sweet onions—including Maui Sweets, Vidalia Sweets, Texas Sweet, and Walla Walla Sweets—lack the sulfuric punch of regular onions.
