Avocado provides lutein for eye and mind

Lutein is a carotenoid—the colorful antioxidant pigments in fruit and vegetables—that is essential to the eye and brain.

In this study, 40 healthy adults, age 50 or older, ate one avocado per day, or a medium potato or one cup of chickpeas, as part of their regular diet. Each avocado provided about 369 mcg of lutein. After six months, lutein levels had increased 15 percent in the non-avocado groups and 25 percent for the avocado group. The avocado group also saw a 26 percent increase in macular pigment density of the eye, and had improved attention and memory in cognitive tests.
