Explain the nutritional composition of kiwifruit and its health benefits, including its high vitamin C content and other nutrients.

Kiwifruit is a nutrient-dense fruit rich in vitamin C, vitamin K, vitamin E, dietary fiber, and antioxidants such as polyphenols and carotenoids. A single kiwifruit provides more than the daily recommended intake of vitamin C, which supports immune function, collagen synthesis, and skin health, as well as antioxidants that protect against oxidative damage and inflammation. Kiwifruit is also low in calories and glycemic index, making it a healthy choice for weight management and blood sugar control.
