Diet heavily impacts brain functioning throughout life. Unhealthy diets high in sugars and fats can cause neuron inflammation while healthy diets with nutrients like omega-3 fatty acids improve neuron formation and brain functions such as thinking and memory. Specific foods like fish, fruits, vegetables, whole grains and legumes support brain health due to vitamins, minerals and antioxidants that nourish the brain and protect against cell damage. Eating a balanced diet with these components along with limiting artificial sugars, trans fats and excess saturated fat can decrease risks of brain disorders and support optimal brain development and functioning.
