Eating grapes daily can help protect the brain against early decline associated with Alzheimer’s disease, show results of a pilot study involving people with early memory decline. Alzheimer’s disease is a brain disease that results in a slow decline of memory and cognitive skills. “The study examines the impact of grapes as a whole fruit versus isolated compounds and the results suggest that regular intake of grapes may provide a protective effect against early decline associated with Alzheimer’s disease,” said lead investigator of the study Daniel Silverman from University of California Los Angeles, US.
“This pilot study contributes to the growing evidence that supports a beneficial role for grapes in neurologic and cardiovascular health, however more clinical studies with larger groups of subjects are needed to confirm the effects observed here,” Silverman added. The study results, published in Experimental Gerontology, showed a grape-enriched diet protected against the decline of metabolic activity. Low metabolic activity in these areas of the brain is a hallmark of early stage Alzheimer’s disease.
