    Lutein

    Kiwifruit contains the phytochemical lutein, which works to prevent agerelated blindness and protect eyes from various kinds of damage. Kiwi juice is also known to have antiinflammatory properties. Kiwi juice is rich in vitamin E and polyphenols, which are known to aid in alleviating inflammatory conditions such as asthma and arthritis. Drinking kiwi juice may also help in treating bouts with constipation. Kiwis produce a substance known as mucilage, which acts as a natural laxative.
