Blueberries May Help Improve Memory

Published March 2010

Daily consumption of blueberries helps improve memory, a preliminary UC study suggests.

The findings, based on a sample of nine older adults with early memory changes, establish a basis for comprehensive human clinical trials to determine whether blueberries are truly effective as a memory enhancer, says investigator Robert Krikorian, PhD, associate professor of psychiatry at UC.

A report on the study appeared in the Jan. 4, 2010, edition of Journal of Agricultural and Food Chemistry.

In the study, one group of volunteers (five men and four women) in their 70s with early memory decline drank approximately 2 ˝ cups of a commercially available blueberry juice every day for 12 weeks.

A control group drank a berry placebo beverage. The blueberry juice group showed significant improvement on learning and memory tests.

"These preliminary memory findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration,” the report says.

This research also involved scientists from the U.S. Department of Agriculture and Agriculture and Agri-Food Canada.
