Onions are one of the most widely consumed vegetables worldwide, and they have been a staple in many cuisines for thousands of years. Not only do they add flavor and texture to a variety of dishes, but they also provide a wealth of nutritional benefits. One of the most significant advantages of onion nutrition is its support for healthy skin. Onions are rich in antioxidants, fiber, and other essential nutrients that can help protect the skin from damage and promote overall health.
Nutritional Profile of Onions
Onions are a nutrient-dense food, meaning they are low in calories but high in essential vitamins, minerals, and antioxidants. One medium-sized onion contains approximately 44 calories, 11 grams of carbohydrates, 2 grams of fiber, and 1 gram of protein. Onions are also a good source of vitamin C, vitamin K, and folate, making them an excellent addition to a healthy diet.
