Foods

An evidence-based guide to the major food groups — what they actually contain, what the science says, and practical guidance for every category.

Food Health Lab Updated July 2026

Our approach: Every guide here is based on the available evidence — large prospective studies, systematic reviews and meta-analyses where they exist, smaller trials or mechanistic evidence where they don't. We name the uncertainty where it exists. No food is a miracle, none is a villain. The goal is to give you the most honest, practical picture available.
