Fatty Fish
Fatty fish is one of the most essential foods for the brain. Examples of fatty fish include trout, herring, sardines, and albacore tuna. Fatty fish usually contain high levels of omega-3 fatty acids [4] which helps improve brain function. Studies show that about 60% of the brain is made up of fat, and omega-3 fatty acids account for half of that. Brain cells use omega-3s to develop brain and nerve cells. These fats also help develop the areas of the brain responsible for learning and memory.
Omega-3s help reduce age-induced mental decline and help reduce Alzheimer’s disease. Studies show that people who do not consume enough omega-3s are more likely to develop learning disabilities and depression. Eating fish regularly helps increase gray matter in the brains, and as a result improving emotions, memory, and decision making.
