Consumption of peanut products improves memory and stress response in healthy adults from the ARISTOTLE study: A 6-month randomized controlled trial

The ARISTOTLE study was a 6-month randomized controlled trial that explored the effects of peanut products on memory and stress response in 63 healthy young adults. Participants consumed either skin-roasted peanuts (SRP), peanut butter (PB), or a control butter (CB). Results showed that SRP and PB improved immediate memory and reduced anxiety and depression scores compared to the control. These benefits were linked to polyphenols and short-chain fatty acids (SCFAs) found in peanuts. The study highlights peanuts as a functional food for enhancing cognitive health and stress-management through their impact on gut-brain interactions and bioactive compounds.

Incorporate 25-32 g/day of skin-roasted peanuts or peanut butter into your diet to potentially improve memory and reduce anxiety. This recommendation is based on a randomized controlled trial, a strong evidence level for causation, though limited to healthy young adults. The findings may not generalize to older populations or those with health conditions. Balance intake with overall calorie needs, and consult a healthcare provider if you have allergies or specific dietary concerns.
