Regular orange eaters are 60 percent less likely to develop a macular disease, one of the most common eye problems that can lead to blindness as we get older, a new research study has discovered. The study tracked the eating habits of more than 2,000 people aged 50 and over for 15 years. The participants were eating other healthy foods and drinks, and especially those that contain anti-inflammatory flavonoids, such as tea, apples and red wine, but it was only those who regularly ate oranges that reduced their chances of macular degeneration.
