An orange a day might keep macular degenearation away, according to a study of more than 2000 adults aged 49 and older. The Westmead Institute for Medical Research in Australia, which conducted the study, found that people who ate an orange daily reduced their risk of acquiring this age-related visual impairment by up to 60 per cent. In addition to vitamin C, oranges have flavonoids, which might explain the effect: These compounds prevent oxidative stress and reduce inflammation in the body.
