Lutein linked to better memory

Carotenoids, the colorful antioxidants in fruits and vegetables, accumulate in brain nerve tissue. The carotenoid lutein supports eye health, but lutein is also important for the brain.

Earlier studies show about 60 percent of the carotenoids in brain tissue are lutein, but lutein makes up only about 12 percent of carotenoids in the typical diet.

In this study, doctors measured circulating and dietary carotenoids in 94 adults, aged 25 to 45. Participants then  completed a task of reconstructing a three-dimensional object from memory. After adjusting for age, gender, and body mass index scores, lutein was the only carotenoid linked to better memory performance in the 3D object reconstruction test.
