Onions

Onions belong to the Allium family of plants, which also includes chives, garlic, and leeks. These vegetables have characteristic pungent flavors and some medicinal properties.

Onions are nutrient-dense, meaning they’re low in calories but high in vitamins and minerals. One medium onion has just 44 calories but delivers a considerable dose of vitamins, minerals and fiber

This vegetable is particularly high in vitamin C, a nutrient involved in regulating immune health, collagen production, tissue repair and iron absorption. Onions are also rich in B vitamins, including folate (B9) and pyridoxine (B6) — which play key roles in metabolism, red blood cell production and nerve function
