Yes, the skin of a kiwi fruit is edible and can be eaten. It contains a high concentration of nutrients, including fiber, folate, vitamin E, and antioxidants such as vitamins C and E. Eating the skin can increase the fiber content by about 50%, and boosts other nutrients by 30-50% compared to eating just the flesh alone. The skin is safe to eat, though some people find its fuzzy texture unpleasant or experience mouth irritation due to calcium oxalate crystals in the skin. Washing and scrubbing the kiwi skin can reduce fuzziness and dirt, making it more palatable. The skin is especially nutritious and provides various health benefits like supporting digestion, immunity, and heart health. Different varieties of kiwi, like the gold kiwi, have smoother skins that can be easier to eat. Overall, eating the skin along with the flesh maximizes nutritional intake and is safe for most people.
