Eating Oranges May Help Ward Off Macular Degeneration
Age-related macular degeneration (AMD) is the leading cause of vision loss in the United States. A recent study suggests that regularly eating oranges may reduce people’s risk of developing macular degeneration.
Participants in the study included more than 2,000 Australian adults over the age of 50 who were followed for 15 years. Dietary intake was assessed using a semiquantitative food frequency questionnaire. Estimates of the flavonoid content of foods were assessed by using the USDA Flavonoid, Isoflavone, and Proanthocyanidin databases. AMD was assessed from retinal photographs.
The researchers also found that the flavonoids in oranges were the nutrient protecting against the eye disease. Flavonoids are naturally occurring antioxidants.
Researchers from Westmead Institute Medical Research conducted the study. It was published on July 6, 2018, in The American Journal of Clinical Nutrition.
Other foods high in flavonoids include citrus fruits, grapes, strawberries, tea, cooked greens and dark chocolate.
