Sydney, July 13: Eat oranges on daily basis, if want to prevent losing your vision as you age and keep your eyes healthy, according to a study led by an Indian origin researcher.
Macular degeneration is a condition associated with old age that causes vision loss at the centre of the field of vision.
The results revealed that people who ate at least one serving of oranges daily had more than 60 percent reduced risk of developing late macular degeneration 15 years later.
However, the effect may be due to the presence of flavonoids in oranges.
Flavonoids are powerful antioxidants present in almost all fruits and vegetables, and they have key anti-inflammatory benefits for the immune system.
“Essentially we found that 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,” said lead researcher Bamini Gopinath from the University of Sydney.
“Even eating an orange once a week seems to offer significant benefits,” It added.
For the study, published in the American Journal of Clinical Nutrition, the team conducted an interview of nearly 2,000 people aged over 50 and followed them over a period of 15 years.
Gopinath explained that previously most of the researches had focused on the impacts of basic nutrients including Vitamins C, E and A on the eyes.
The research team also looked at other flavonoid-containing foods such as tea, apple, red wine. But in the end, they did not find any relation between other sources and protection of eyes against the disease.
Age is usually considered as the strongest known risk factor and the disease is more likely to occur after the age of 50.
