Consuming this portion provides a wealth of nutritional benefits, including dietary fiber, vitamin C, and potassium, all packaged in a low-calorie fruit. The composition is largely water, which contributes to a feeling of fullness without adding a significant number of calories. The skin, which is included in the 100g serving, is where a substantial portion of the fiber and antioxidants are found, highlighting the importance of eating the fruit whole and unpeeled when possible.
