July 26, 2006 -- Eating a low-fat vegan diet may be better at managing type 2 diabetesdiabetes than traditional diets, according to a new study.
Researchers found 43% of people with type 2 diabetes who followed a low-fat vegan diet for 22 weeks reduced their need to take medications to manage their disease compared with 26% of those who followed the diet recommended by the American Diabetes Association (ADA).
In addition, participants who followed the vegan diet experienced greater reductions in cholesterol levels and weight lossweight loss than those on the other diet.
A vegan diet is plant-based and consists of vegetables, fruits, grains, and legumes and avoids animal products, such as meat and dairy. People who are on a vegan diet are at risk for vitamin B12 deficiency, and so B12 vitamins were given to the participants on that diet.
"The diet appears remarkably effective, and all the side effects are good ones -- especially weight loss and lower cholesterol," says researcher Neal D. Barnard, MD, adjunct associate professor of medicine at the George Washington University, in a news release. "I hope this study will rekindle interest in using diet changes first, rather than prescription drugs."
Barnard is also president of the Physicians Committee for Responsible Medicine, a nonprofit health organization that opposes animal research and advocates a vegan diet.
Vegan vs. ADA Diet for Diabetes
In the study, published in the journal Diabetes Care, researchers compared the effects of following a low-fat vegan diet and the ADA diet on reducing the need for drugs to manage diabetes, kidney function, cholesterol levels, and weight loss in 99 adults with type 2 diabetes. Meals were not provided, but participants met a dietitian to come up with a diet plan and then met regularly each week for nutritionnutrition and cooking instruction.
Forty-nine of the participants followed a low-fat vegan diet consisting of about 10% of daily calories from fat, 15% protein, and 75% carbohydrates. They were asked to avoid animal products and added fats and instead favor foods like beans and green vegetables, but portion sizes and total daily calories or food intake were unrestricted.
