Year: 2010
Type: review
Study designs: Systematic Review, Meta-Analysis
Abstract: Objective: To use a meta-analysis approach to analyze the effectiveness of a vegetarian diet (exclusion of all meat) in comparison to a conventional diet containing ~15-20 % protein, ~50-60% carbohydrates, ~25-30% fat with less than 7% coming from saturated fat, and less than 200mg of cholesterol in the treatment and management of type 2 diabetes mellitus.Methods: A meta-analysis was used which included 3 randomized controlled trials and 1 crossover controlled trial that assessed the impact of employing a vegetarian diet in type 2 diabetes mellitus patients.MEDLINE, the Cochrane Database, and the Database of Abstracts of Reviews of Effectiveness were searched for articles published in English and other languages from January 1999 to January 2010.Reference lists of the retrieved articles were searched to identify other eligible studies.Results: The vegetarian diet decreased HbA 1C , body weight, total cholesterol, and low-density lipoprotein (LDL) cholesterol significantly more than the control diet.It also had a less significant impact on the highdensity lipoprotein than the conventional diet.No significant distinctions in fasting glucose were observed. Conclusion:This meta-analysis shows that a vegetarian diet is more effective than a typical diet (described above) in the maintenance of type 2 diabetes.
