Macular degeneration is caused by the deterioration of the central portion of the retina, the inside back layer of the eye that records the images and sends them through the optic nerve from the eye to the brain. The retina’s central portion-macula, is responsible for focusing central vision in the eye, and it controls human’s ability to read, recognize faces or colors, and see objects.
Research conducted at the Westmead Institute showed that flavonoids in oranges prevent eye disease, people who eat at least one serve of orange every day have a reduced risk of developing macular degeneration compared with people who never eat oranges.
Flavonoids are powerful antioxidants found in almost all fruits and vegetables, and they have important anti-inflammatory benefits for the immune system. Common foods that contain flavonoids are tea, apples, red wine and oranges.
The research compiled data from the Blue Mountains Eye Study, a benchmark population-based study that started in 1992. One of the world’s largest epidemiology studies, measuring diet and lifestyle factors against health outcomes and a range of chronic diseases.
