A handful of peanuts a day helped older brains respond better to insulin

A simple snack may do quiet good for the ageing brain. In a 16-week study from Maastricht University Medical Center in the Netherlands, older adults who ate unsalted, skin-roasted peanuts every day showed better insulin responsiveness in brain regions tied to memory — including the hippocampus. Insulin is a hormone that helps the brain's cells communicate and stay healthy, and the brain's response to it tends to dull with age. 'Our study found that daily peanut consumption beneficially affected insulin responsiveness in memory-related brain regions in older adults,' said senior author Dr Peter Joris. The findings were published in the peer-reviewed journal Food & Function.
