Onions are nutrient-dense, which means they have few calories but a lot of vitamins and minerals. One medium onion contains just 44 calories but is high in vitamins, minerals, and fiber. This vegetable is abundant in vitamin C, a substance that aids in immunological health, collagen formation, tissue repair, and iron absorption. Vitamin C also functions as a potent antioxidant in the body, shielding cells from harm caused by unstable molecules known as free radicals. Onions are particularly high in B vitamins, such as folate (B9) and pyridoxine (B6), both of which are essential for metabolism, red blood cell synthesis, and neurological function.

Finally, they are a wonderful source of potassium, a mineral that many individuals need. In reality, the average potassium consumption in the United States is little more than half the recommended daily value (DV) of 4,700 mg. Potassium is required for normal cellular activity, fluid balance, neuronal transmission, renal function, and muscular contraction.
