Yes, it is safe and nutritious to eat kiwi skin. The skin contains a high concentration of fiber, vitamin E, folate, and antioxidants such as vitamins C and E that provide significant health benefits. Eating the skin can increase your intake of these nutrients by 30% to 50%. However, some people may find the fuzzy texture unpleasant or experience mouth irritation due to calcium oxalate crystals present in the skin. Washing the skin well before eating and rubbing off some fuzz can make it more palatable. Overall, eating kiwi with the skin on is a healthy choice that also helps reduce food waste.
