Oranges keep macular degeneration at bay

The effect may be due to flavonoids present in oranges that help prevent vision loss. The Centers for Disease Control And Prevention said it is a major cause of blindness worldwide and the leading cause of vision loss for Americans aged 65 years and older. "Essentially, 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", she said.

"Our research is different because we focused on the relationship between flavonoids and macular degeneration", she said.

Around 600,000 people in the United Kingdom now have sight loss caused by the incurable disease and around 70,000 new cases are diagnosed every year, equivalent to almost 200 per day.

These flavonoids have been linked to anti-inflammatory boosts for the immune system for a number of years, but this is the first time they've been analysed in connection with this eye disease, which affects millions of people over the age of 50.

Why should you eat oranges?

How often one should eat oranges? Flavonoids are powerful antioxidants found in nearly all fruits and vegetables, and have anti-inflammatory benefits for the immune system.

Study's lead researcher and associate professor Bamini Gopinath at the University of Sydney said the information demonstrated that flavonoids in oranges seem to help being protected against the eye illness.

The investigation was focused on more than 2,000 Australian adults over the age of 50, who were tracked over the course of 15 years.

In the experiment, the experts found that those who ate at least one orange a day, the risk of retinal was 60 percent lower.

Scientists say that even if a man eat oranges and citrus fruits only once a week, even in this case, eye health will improve.

The researchers also examined common foods that contain flavonoids, such as tea, apples, red wine and oranges. However they did not find any relation between other sources and protection of eyes against the disease.

The researchers looked at data from the Blue Mountains Eye Study, a population-based study in Australia that got underway in 1992.

The authors of the paper acknowledged the correlation doesn't mean eating oranges is proven to prevent macular degeneration, and further studies are needed to validate the findings.
