The study was conducted, among others, by doctors Neal Barnard and David Jenkins.
It compared a low-fat vegan diet to a typical diabetes diet based on the guidelines of the American Diabetes Association. The participants were individuals with type 2 diabetes.
These were the results after a 74 week study period (58):
- Vegan group lost 9.7 lbs, diabetes diet group lost 6.6 lbs. The difference was not statistically significant.
- Only after adjustments (statistical manipulation) were there small advantages for the vegan diet for HbA1c (-0.40% vs +0.01%), Total cholesterol (-20.4 vs -6.8 mg/dL) and LDL (-13.5 vs -3.4 mg/dL).
- No difference in weight, BMI, waist circumference, HDL cholesterol, triglycerides, blood pressure, fasting blood sugars or CRP levels.
Really… this is it. These are the “miraculous” benefits of the vegan diet in the most comprehensive study on a low-fat vegan diet to date.
Not quite as impressive as the vegan docs make it out to be in their books and documentaries…
Keep in mind that the lead researchers are both vegans themselves, so they should be able to set up a study that maximizes the benefits of such a diet.
There is absolutely nothing groundbreaking about these results. Studies on other diets, like Mediterranean, paleo or low-carb, have lead to similar and often much better results.
Given all the hype about vegan diets, I have to say that the results are underwhelming… to say the least.
