According to Fernando Gómez-Pinilla, PhD, a neurobiologist at UCLA who studies the impact of certain foods on the brain, the key is to avoid fried foods and add more omega 3 fatty acids to your diet. Omega 3s are essential for normal brain functioning because they are our primary source of DHA (docosahexaenoic acid), the most abundant omega 3 fatty acid found in the cell membranes of brain cells. Scientists believe that DHA protects against "normal wear and tear" on the brain, helps promote brain growth, enhances learning and memory and improves communication between synapses.
