Researchers using data from the Third National Health and Nutrition Examination Survey (1988 through 1994) have found evidence that consuming vitamin D may help ward off age-related macular degeneration (AMD).
In this study, 7752 individuals (including 11% with AMD) were given retinal photographs, dietary intake questionnaires, and blood tests to calculate blood vitamin D (25-hydroxyvitamin D) levels. Based on these vitamin D blood levels, participants were divided into 5 groups. Participants in the group with the highest vitamin D levels showed 40% lower risk of developing early AMD than those in the lowest group.
Analysis was also conducted to evaluate associations with important food and supplemental sources of vitamin D.
- People who drank milk daily decreased their risk of developing AMD, as did those who took supplemental vitamin D consistently but didn’t drink milk daily.
- Fish consumption was also linked with a lower risk of advanced AMD.
What are good sources of vitamin D? Consider fish — it’s naturally rich in vitamin D. Milk and breakfast cereals are generally fortified with vitamin D as well.
