Barnard et al. — Low-fat vegan diet for type 2 diabetes
In plain English
Adults with type 2 diabetes were randomly assigned to a low-fat vegan diet or the standard American Diabetes Association (ADA) diet. The vegan arm beat the ADA arm on glycaemic control (HbA1c), LDL cholesterol and weight loss. It was one of the first head-to-head trials to put a whole-food vegan approach above the prevailing standard of care.
Why it matters
Low-fat vegan diet > ADA diet for glycaemic and lipid control.

Caveats
Small sample; PCRM is an advocacy organisation, which is disclosed. Independent replications (e.g. DiRECT 2018) have since corroborated the broader 'whole-food remission' finding.
