What key micronutrients, essential for immune response, collagen production, and iron absorption, are frequently highlighted as being present in onions?
Answer
Vitamin C, B vitamins (folate and B6), and potassium
Onions are noted for their nutrient density, providing significant amounts of essential micronutrients despite being low in calories. The primary micronutrients consistently highlighted across various onion types include Vitamin C, certain B vitamins specifically folate and B6, and the mineral potassium. Vitamin C plays a crucial role in supporting the body's immune response, assisting in the necessary production of collagen, and enhancing the body's ability to absorb iron from dietary sources. Potassium, another highlighted component, is functionally essential for maintaining proper fluid balance within cells, ensuring efficient nerve transmission, and facilitating muscle contraction.
