5 Aspects of a Study Showing How Vitamin C can Help Prevent Cataracts

04-18-16 park ID-100317550 tiveryluckyCataracts, the world’s leading cause of blindness, may develop more slowly in those individuals who eat a diet rich in vitamin C. This information is based on results of a study conducted by King’s College London and published in March by the American Academy of Ophthalmology. Cataracts develop with age and slowly affect the eye’s lens turning it from clear to opaque. Dr. Beth Friedland can remove the clouded lens and replace it with a new artificial lens. However, Triangle area residents may reduce their risk of developing cataracts by as much as a third if their diets include foods such as dark green leafy vegetables, bell peppers, citrus fruits, papaya, kiwifruit, berries, guava and broccoli.  Dr. Beth R. Friedland of the Triangle-based Park Ophthalmology recommends that patients build those foods into their diets rather than relying on store shelf vitamin supplements.

Park Ophthalmology offers five important details about the study:

  • Female twins: The study used data from more than 1,000 pairs of female twins, asking them about their diet. At the age of 60, the twins’ eyes were examined for the presence of cataracts. Those whose diets included the most vitamin C were 20 percent less likely to have cataracts than other participants.
  • Results: The twins’ eyes were examined again at age 70. Those with the most vitamin C in their diets had a 33 percent risk reduction in cataract development.
  • Genetics: Researchers found that genetics played less of a role in cataract development than did diet. According to the American Academy of Ophthalmology, this is the first study to show that result.
  • Vitamin C benefits: The fluid inside the human eye is naturally high in vitamin C. It is possible that vitamin C’s antioxidant properties help prevent cataracts.
  • Supplements: These results make it tempting to reach for the bottle of vitamin C tablets, but the study only examined diet-based vitamin C, not supplements.

As a clinical associate professor at the UNC-Chapel Hill School of Medicine, Dr. Friedland closely follows the latest research in eye health so she can provide her Park Ophthalmology patients with the best vision care.
