5 Foods That Fuel Your Brain (Slideshow)

Carrots are so quick and easy to grate, and they're also very rich in beta-carotene (hence the name). Try adding grated carrots to salads.

Salmon, tuna, and halibut all have high levels of omega-3 fatty acids. Try to incorporate one of these into your dinner plans at least once a week.

Guacamole is a fun party food, but it doesn't have to be reserved for special occasions. Make some guacamole and set out Popchips for your family to nosh on while dinner is in the oven. Avocados are rich in vitamin C, which will help you remember the fond memories you're creating.

Replace starchy white potatoes with beta-carotene-rich sweet potatoes. You can bake them, mash them, or make them into fries — just as you would with the white potato.

Walnuts are rich in omega-3 fatty acids, so they are a good alternative if you don't like fish. Flaxseed is another non-fishy source of this essential fat.
