Your diet plays a big role in brain function. Do your best to eat more vegetables, fruits, nuts, legumes, whole grains, and seafood, while eating fewer fatty meats, full-fat dairy products, sugary drinks, and sweets. By eating healthfully, you’ll get nutrients that improve brain health such as vitamin E, B vitamins, and omega-3 fatty acids.
Wash everything down with plenty of water and other fluids. Good hydration has been associated with better concentration and enhanced short-term memory.
