The authors speculated on what else could be beneficial about a vegan diet. Observational. evidence has shown that these dietary constituents are associated with a reduction in type 2. Vegetarian diets contain substantially less saturated fat than nonvegetarian. The vegetarian diet. We did not. calculate the glycemic load of the diets.

They have been successful in reducing diabetes medication and blood sugar levels. Korea (2. 01. 6)The focus of this clinical trial was to compare the effect of a vegan diet to a conventional diabetic diet, as prescribed by the Korean Diabetes Association (KDA), on glycemic control among Koreans (1. The trial lasted three months. The vegan diet group had 4. KDA diet group had 4. After three months, there was a statistically significant, greater reduction in Hb. A1c in the vegan group compared to the KDA group (0. When including only participants with high diet compliance, the vegan diet fared even better (0. The vegan group ate less calories and saturated fat than the KDA group. However, neither group's blood pressure or LDL- cholesterol went down. The vegan group's triglycerides went up while the KDA group's went down; this might indicate the vegan group was eating more simple sugars. Czech Republic (2.

The vegetarian diet group had a greater reduction in diabetes medication (4. Hb. A1c, waist circumference, and body fat. LDL cholesterol went down 8% in the vegetarian group only, but HDL cholesterol went up in the control group. Exercise caused the positive differences for the vegetarian diet to be even greater and also raised the HDL in the vegetarian group. The authors stated: Several possible mechanisms may explain the beneficial effects of a vegetarian diet: higher intake of fibre, lower intake of saturated fat . A vegetarian diet was reported to reduce intramyocellular lipid concentrations and this, together with the effect on visceral fat which we observed, might be responsible for a substantial portion of the effect of a vegetarian diet on insulin sensitivity and enzymatic oxidative stress markers. And, oddly enough: Especially during exercise, it became evident in our trial that it was easier for subjects to follow a vegetarian diet than a conventional diabetic diet. PCRM 2. 00. 4- 0. Study. In 2. 00. 4, researchers affiliated with the Physician's Committee for Responsible Medicine (PCRM) started a 7. American Diabetes Association recommended diet for people with type 2 diabetes.
