• The study published in this month's American Journal of Clinical Nutrition suggests that eating more fruits and vegetables may protective against cataracts.
• A cataract is a clouding of the eye's lens that can cause fuzzy or blurred vision and can lead to blindness if untreated.
• Although aging is the most common cause of cataracts, they can occur at any time of life.
• A large study showed that the incidence of cataracts in people who took vitamin C supplements for 10 years or longer was significantly lower than for those who did not.
• This recent study looked at about 35,000 healthy women over 45 who were involved in the Women's Health Study --- an ongoing study of female health professionals in the U.S.
• Over a ten year period, about 2,000 of these women developed cataracts.
• The women who reported eating the most fruits and vegetables had a lower risk of developing cataracts than those who ate less.
• Most studies have looked at specific things in fruits and vegetables that might account for this effect.
• This is one of the few that have looked specifically at total fruit and vegetable intake.
• There are many possible reasons for this effect including the likelihood that those who ate more fruits and vegetables consumed more vitamin C and lutein.
• The study authors conclude: "The possible beneficial effects of fruits and vegetables ...
• warrant the continued recommendation to increase total intake of fruits and vegetables."
• Research has also looked at the role of fruits and vegetables and reduced risk of age-related macular degeneration.
• Lutein and zeaxanthin are two antioxidants that are shown to help reduce risk.
• Lutein is found predominantly in green leafy vegetables and zeaxanthin is also found in greens as well as red peppers and corn.
