Fruit skin is the outer protective layer of fruits, serving several important functions. It helps to shield the inner flesh from pests, diseases, and environmental factors. Additionally, the skin often contains nutrients, vitamins, and antioxidants that can be beneficial for health. Different fruits have varying types of skin, such as the smooth skin of apples or the thick, rough skin of oranges. The texture and color of fruit skin can also indicate ripeness and flavor. Eating the skin of many fruits, like kiwis and peaches, can enhance the nutritional value of your diet.
