Need another reason to add fish to your diet? It may help preserve your eyesight.
In a new study, Australian researchers found that eating just one serving of fish a week was associated with reduced risk of age-related macular degeneration. AMD is a slowly progressing condition that causes a loss of "central" vision, making it hard or impossible to see or discern objects right in front of you. People older than 60 are at greatest risk for AMD.
Researchers believe omega-3 polyunsaturated fatty acids found in many fish help protect against AMD. Among the fish highest in fatty acids are salmon, halibut and tuna. Fatty acids also are found in walnuts, almonds and pine nuts, leading the researchers to conclude that "regular consumption of nuts may also reduce AMD risk."
