Popular snack may help support brain health in older adults, new study finds
A small Maastricht University study found that older adults who ate 60 grams of unsalted, skin-roasted peanuts daily for 16 weeks showed improved insulin responsiveness in memory-related brain regions and about 4% more brain blood flow. Preventive neurologist Kellyann Niotis cautions the study was too small to show peanuts prevent Alzheimer's, favoring overall dietary patterns instead.
