59. The neuroscience of polyphenols: New research on brain function

Can polyphenols—found in berries, teas, and dark chocolate—actually enhance brain function? A new clinical trial from Nutrients (Feb 2025) by Carrillo et al. investigates whether a polyphenol-rich supplement improves cognition and boosts key brain biomarkers (BDNF and CREB) in healthy adults.In this episode, we break down the study’s design (92 participants, crossover trial), the cognitive tests they used, and the eye-opening results: better attention, higher cognitive scores, and increased neuroprotective proteins.What does this mean for brain health and prevention? Should you rely on supplements or stick to whole foods? We discuss the implications and share our take.Tune in now for science-packed insights that could shape your cognitive future!Reference: Carrillo, J.Á.; Arcusa, R.; Xandri-Martínez, R.; Cerdá, B.; Zafrilla, P.; Marhuenda, J.
