Diets rich in fish and vegetables may boost your brain power


Kale and salmon, anyone? The foods you choose for meals and snacks may help you build a stronger body and help preserve brain function.

Scientists at the National Eye Institute studied how plant-based foods of the Mediterranean diets could affect our eyes as we age. The study tracked 4,000 participants over a 10-year period, checking their brain function every few years. In addition to their eye-related research, the scientists had two key findings around brain function and aging.

People following a Mediterranean-style diet had a lower risk of brain function decline. Additionally, this type of healthy diet is associated with slower brain function decline.

The Mediterranean diet is a heart-healthy approach to eating. It focuses on fruits, vegetables, whole grains, nuts, legumes, fish, and olive oil. In the study, eating a diet rich in fish and vegetables appeared to have the most positive effect. Study participants who ate the most fish had the slowest rate of brain function decline.
