Peanuts May Help Boost Brain Health
A new study suggests that eating 2 daily servings of peanuts may help support brain health in older adults. With more than 7 million Americans living with Alzheimer’s in 2025 and no cure available, lifestyle choices like diet are an important area of research.
The new study focuses on the impact of eating skin-roasted peanuts on brain health. The research found that peanuts can increase blood flow to the brain, notably in areas tied to memory and thinking.
The research examined how peanuts impact blood flow in adults aged 60 to 75. According to the American Brain Foundation: “blood flow delivers oxygen and other essential nutrients for cognitive functions, including memory, focus and problem solving to the brain.”
Since medical providers often recommend making dietary changes to help with the risks of Alzheimers, this research focused on peanuts, since they are rich in nutrients linked to heart and blood vessel health, including protein, healthy fats, antioxidants and L-arginine – an amino acid involved in regulating blood flow. The study used skin-roasted peanuts because the skins contain extra fiber, protein, and antioxidant compounds.
Participants in the research went through a 16-week control period where they totally avoided eating peanuts and tree nuts. During the test period, participants ate 60 grams of unsalted, skin roasted peanuts per day. During the peanut phase, the participants saw a boost of 36% in brain blood flow. The subregions of the brain involved in memory and decision making showed even greater improvements. The research also showed a small improvement in verbal memory during the peanut phase.
Findings in the study suggest that peanuts can enhance brain function by improving cerebral blood flow. The research suggests that 2 daily servings of peanuts appear to be a positive addition to the diet of senior Americans. So add some skin roasted peanuts to your diet!!!
