Walnuts for the brain
Here's why: Walnuts, with their funky lobe-like shape, are a great source of essential omega-3 fatty acids, which help brain cells communicate with each other and are essential to cognitive performance, memory, and nerve health.

Carrots for the eyes
Here's why: Carrots are rich in beta-carotene, which the body converts to vitamin A. Your eyes need A to maintain the health of the cells in your corneas, the transparent tissue that covers the eye and protects it from germs, dust, inflammation, and infection. Is it any wonder, then, that a sliced carrot reveals concentric circles that look like your pupil and iris?

Grapes for the heart
Here's why: Red and purple grapes (along with other dark fruits and vegetables) contain flavonoids, which experts say protect against heart disease, as well as cancer and brain-aging. A recent study from the University of Michigan also found that the heart-shaped clusters of fruit may help control your blood pressure.
