Analyzing dietary patterns and risk of AMD in a Maryland-based population.
Researchers at Johns Hopkins University in Baltimore, Maryland have identified a negative correlation with fish and shellfish consumption and incidence of age-related macular degeneration (AMD) in a Maryland population of over 2500 people. The results are published in the December issue of Ophthalmology.
Utilizing food frequency questionnaires, the team of academic researchers assessed weekly fish and shellfish consumption in 2520 residents of Salisbury, Maryland, age 65 to 84 years old.
Fundus photographs were then taken of subject eyes to determine the presence of drusens (yellow spots in the retina) and other signs of AMD.
Results of the study showed that subjects with advanced AMD were far less likely to consume fish or shellfish high in omega-3s. Another find from the study was a lack of relationship between AMD and consumption of crabs and oysters combined-both of which are high in zinc.
These findings appear to support evidence of omega-3 intake as being a benefit for eye health. To read the study abstract, click here.
