Can you remember the last time you had fish for dinner? If you can't recall, it could be more than the passage of time that's to blame. Improved memory is just one of many brain-boosting benefits associated with eating more fish.

An omega-3 fatty acid known as DHA, is required to keep the brain functioning normally and efficiently. Long-term, consistent intake of adequate DHA is linked to improved memory and reduced rates of cognitive decline. Low levels of DHA have been associated with a greater risk of cognitive disease in later years.

The 2020-2025 Dietary Guidelines for Americans recommends adults consume at least 8 ounces of seafood per week. Oily fish such as salmon, tuna, Atlantic mackerel, herring and trout are great options to fuel your brain with this important omega-3 fatty acid. Try broiling or grilling your fish instead of deep frying this delicious brain food.

Fish is also a lean protein. Aside from being lower in saturated fat than red meat, swapping burgers for tuna means more omega-3s, which studies suggest may reduce the risk for heart disease.
