Polyphenols: Metabolism, Cellular Signals, and Human Data
Polyphenols are a diverse group of plant compounds, not a single antioxidant drug. This overview explains their metabolism and microbiota, Nrf2 and the limits of cellular mechanisms, and research on vascular health, cocoa, berries, and resveratrol. We specifically address negative clinical outcomes, risks of concentrated catechins, and practical dietary choices.
