Barnard, ND, Cohen, J, et al. A Low-Fat Vegan Diet and a Conventional Diabetes Diet in the Treatment of Type 2 Diabetes: A Randomized, Controlled, 74-Wk Clinical Trial. Am J Clin Nutr 89(5)1588S-96S. PMC2677007
This study compared two groups of people following a pre-assigned diet. Free-living individuals with type 2 diabetes were randomly assigned to a low-fat vegan diet or a diet following 2003 American Diabetes Association guidelines. The vegan diet appeared to have a more pronounced effect on blood lipids and blood glucose than the conventional diet.
