Eating too much red meat may raise the risk of going blind by 50 per cent, according to a recent study.
The study by Dr Elaine E-W. T. Chong from the Centre for Eye Research Australia at the University of Melbourne, and supported by awards from the National Health and Medical Research Council, the Ophthalmic Research Institute of Australia and others bodies was published in the American Journal of Epidemiology, a peer-reviewed medical journal.
It said that research has shown that eating red meat at least 10 times a week makes people more likely to develop age-related macular degeneration (AMD).
The study followed 5,600 middle-aged men and women for 13 years. The researchers say that they took into account several known major risk factors for AMD, such as smoking. They admit however, that rather than directly raising the risk of AMD, red meat consumption could actually be a marker for other lifestyle factors that are causing the damage.
The researchers obtained their data from the Melbourne Collaborative Cohort Study of 41,528 Melbourne residents (17,049 men) between the ages of 40 and 69 who were recruited between 1990 and 1994. During follow-up between 2003 and 2006, all the participants had eye examinations and retinal photographs of both eyes were taken.
