Food and mood: how do diet and nutrition affect mental wellbeing?
by Joseph Firth, James E. Gangwisch, Alessandra Borsini, Robyn E. Wootton, Emeran A. Mayer · The BMJ (BMJ 2020;369:m2382)
BMJ review of the evidence linking dietary patterns to depression and cognition, covering Mediterranean-diet trials, gut microbiome pathways, and micronutrient supplementation. States plainly where causal evidence holds, where findings remain observational, and where intervention trials returned null results. Directly serves the 'mental well-being' half of the topic note, which is where holistic-nutrition content is most prone to unfalsifiable claims. The review is notable for explicitly flagging weak and null evidence, so it models how to read this literature rather than selling a conclusion.
