Omega-3 fatty acids: Omega-3 fatty acids are one of several polyunsaturated fatty acids found in the brain and are important for brain development and function. Synapses are rich in some O3FAs, which suggests that this fatty acid is involved in signal transmission along neurons. Sardines, flax seeds and walnuts are excellent sources of omega-3 fatty acids as well as halibut, shrimp, cod, tuna, soybeans, tofu, kale, collard greens, and winter squash. -torrance stephens
