Grapes

Overview

Grapes provide resveratrol, a polyphenol that activates SIRT1, enhancing NAD+-dependent processes and supporting mitochondrial function. Red and purple grape varieties additionally supply anthocyanins built on Malvidin, Cyanidin, Delphinidin, Peonidin, and Petunidin backbones (green/white grapes contribute little anthocyanin).

Within the BRAIN Diet framework, polyphenols (e.g., resveratrol) activate SIRT1, enhancing NAD⁺-dependent processes, and are found in grapes, blueberries, cranberries, peanuts, and dark chocolate.

Food Context

Synergies

• Part of diverse polyphenol intake
• Pair with other resveratrol sources

Preparation
