Improving Diabetes with a Low-Fat Vegan Diet

posted 4/30/09

A new report from PCRM researchers, published in the American Journal of Clinical Nutrition, shows that a low-fat vegan diet helps people with diabetes lose weight and improve their blood sugars and cholesterol. Earlier publications had shown that the diet is effective over the short term. The new publication shows that benefits persisted for a year beyond the initial 22-week study period. Vegan group participants lost on average 9.7 pounds, compared to 6.6 pounds for people on a more conventional diabetes diet. Improvements in hemoglobin A1c levels (a measure of blood sugar over time) and total and LDL cholesterol were also greater in the vegan group. Recent reports from the same group showed that nutrition improvements were greater in the vegan group and that acceptability of the diet was comparable to seemingly more permissive diets.
