Fatty Fish
When it comes to brain foods, the list can’t be completed without fatty fish. From sardines and trout to salmon, they are all perfect sources of omega-3 fatty acids. It is important to know that the brain is mostly comprised of fat, with more than 50% of that is the omega-3 category. These substances play an essential role in building nerve and brain cells as well as boosting your memory and learning capabilities. More importantly, omega-3 fatty acids can slow mental decline in older adults and help prevent Alzheimer’s disease. A low level of this nutrient would lead to depression and learning impairment. [2]
