David Perlmutter
b. 1954 · United States · Functional Medicine, Neuroscience
Neurologist who put diet, glycemia and the microbiome at the centre of brain health.
Core concepts
- Diet, glycaemic load and neurological function
- The gut microbiome as a modulator of brain health
- Inflammation as a shared mechanism in neurodegeneration
Key writings and teachings
- Grain Brain (2013)
- Brain Maker (2015)
- Drop Acid (2022)
Influence on modern practice
Perlmutter popularised the gut–brain axis for a mass readership years before microbiome research entered routine neurology discussion, and helped normalise dietary counselling in neurological practice. Nutrition researchers dispute his gluten and carbohydrate claims as outrunning the evidence, and the objections are well documented in peer-reviewed commentary.

Contribution traced forward
Diet, glycaemia and the microbiome as determinants of brain health.
What modern research says
- EstablishedCheck the literature — PubMed ↗
Multidomain lifestyle trials (FINGER and its worldwide replications) show cognitive benefit in at-risk older adults.
- ContestedCheck the literature — PubMed ↗
The specific gluten–brain claims popularised in Grain Brain are not supported outside coeliac disease and gluten sensitivity.
Clinical protocols
- World-Wide FINGERS multidomain prevention protocols in over 40 countries
- Metabolic screening in memory-clinic intake
Real-world uses
- Public messaging that pushed glycaemic control into consumer brain-health products
- Microbiome testing services marketed for cognitive outcomes, largely ahead of the evidence
