People with a genetic predisposition for age-related macular degeneration (AMD) increase their odds of developing it if they have a history of heavy smoking, not eating enough fruits and vegetables and are inactive.
The National Institutes of Health funded study looked at the diet and exercise patterns of more than 1,600 women categorizing participants into lowest, moderate and highest-risk groups.
Women with who carried two genetic risk factors for AMD and smoked were four times more likely of developing it compared to women with no genetic risk factors, who ate a healthy diet and got at least ten hours of light exercise in a week.
Researchers say these findings show if you have a family history of the eye disorder which can leave you blind.
You can potentially lower your risk of developing it yourself through healthy lifestyle behaviors.
Findings appear in the journal ‘Ophthalmology.’
