Most are familiar with the benefits of adding omega-3 fatty acids into daily consumption. Fish, such as tuna, carry nutrients that aide in the health of a person’s heart and mind – helping to prevent ailments such as Alzheimer’s and Coronary Heart Disease.
Interestingly, a study by the Wilmer Eye Institute at John Hopkins University hinted that the source of the derived fatty acids may offer an additional positive difference: Better vision. When subjects added shellfish to their diet at least once a week, like crab or oysters, their risk of age-related macular degeneration (AMD) decreased by 60 percent.
When researches asked a group of over 2,391 participants between the ages of 65 and 84 about shellfish consumption, those who ate shellfish on a regular basis who did not suffer from AMD equaled 1,943. Even though more research needs to be done on the effects of zinc levels in shellfish, medical professionals are confident there is a link between diet and vision loss.
As a chronic disease, there is currently no cure for AMD, which kills eye cells responsible for seeing fine detail. The National Eye Institute reports AMD to be the leading cause of vision loss for those over 60 years. Currently, 1.8 million Americans over age 40 live with AMD
