Flavanols, an ingredient present in cocoa might reverse age-related memory decline, a study appear in Nature Neuroscience reported.
The study was conducted in 37 healthy volunteers aged between 50 and 69 years of age. The study participants were given a daily drink of either high flavanols of 900 mg or 10mg for three months.
Brain scans and blood tests were performed before and after the study to assess the memory performance in the volunteers. Additionally, a 20-minute pattern recognition exercise for memory testing was conducted.
Improved brain blood flow with significant memory improvements were observed in the high flavanol received individuals.Naturally occurring food such as green tea, grapes, blueberries and some vegetables are rich sources of flavanols.
