Peanut consumption linked to improved brain insulin response in older adults

Researchers at the NUTRIM Institute of the Maastricht University Medical Center in the Netherlands have found that daily consumption of peanuts may positively influence brain health in older adults. A controlled study involving 31 healthy participants aged 60 to 75 demonstrated that eating 60 grams of unsalted, roasted peanuts with their skins daily for 16 weeks improved the brain's response to insulin.

The observed changes occurred in specific brain regions associated with memory processing and storage, including the hippocampus and the lingual gyrus. Scientists suggest that improved insulin sensitivity in these areas could support cognitive functions and potentially offer protection against age-related decline. The peanuts provide essential nutrients such as plant protein and L-arginine, which are linked to learning and memory processes.
