Summary:
A surprising new study suggests that eating peanuts every day could help support brain health and memory in older adults. Researchers found that consuming about two servings of unsalted, skin-roasted peanuts daily for 16 weeks improved insulin responsiveness in brain regions important for memory, a function that often weakens with age and has been linked to Alzheimer's disease. Eating peanuts every day may offer surprising benefits for the aging brain. Researchers at Maastricht University Medical Center in the Netherlands have found that regularly consuming unsalted, skin-roasted peanuts can improve how certain brain regions respond to insulin in older adults. The findings come from the Institute of Nutrition and Translational Research in Metabolism (NUTRIM) and were published in the peer-reviewed journal Food & Function.
Although insulin is best known for regulating blood sugar, it also plays an essential role in the brain. It helps nerve cells grow, survive, and communicate with one another, supporting memory and other cognitive abilities. Healthy insulin signaling may also help protect against processes associated with Alzheimer's disease.
