Fish With Omega-3 Fatty Acids Reduce Risk of Blindness

Age-related macular degeneration is the leading cause of blindness in Americans over 65. Impaired vision precedes blindness. A recent study linked consumption of omega-3 fatty acids with 30% lower risk of developing macular degeneration. Believe me, it’s a lot better to prevent it than try to treat it once present.

(I have a couple older relatives with macular degeneration, so I pay close attention to the scientific literature.)

What’s the best source of omega-3 fatty acids? Our friend, the fish. Especially cold-water fatty fish such as tuna, trout, sardines, herring, mackerel, halibut, and sea bass. A few plants are also decent sources, but our bodies don’t utilize those omega-3 fatty acids as well as they do from fish.

Note that both the Advanced Mediterranean Diet and Ketogenic Mediterranean Diet feature fish.
