Can a genetic test for eye disease inspire healthier habits?

This study looked at whether telling healthy adults their genetic risk for age-related macular degeneration (AMD) encourages them to eat more carotenoid-rich foods, which are good for eye health. Eighty Caucasian participants aged 18 to 64 without AMD were given genetic risk information and then had their skin and eye carotenoid levels measured over a year. The goal was to see if knowing their risk led to positive lifestyle changes, not to treat or cure the disease.
