Vegetarian Diets And Glycemic Control In Diabetes: A Systematic Review And Meta-analysis
Notes for this study:
||Consumption of vegan or vegetarian diet was associated with a non-significant reduction in fasting blood glucose concentration (-0.36 mmol/L; 95% CI, -1.04 to 0.32; P=0.301; I(2)=0; P for heterogeneity =0.710), compared with consumption of comparator diets
|Number of Subjects
||18-29, 30-44, 45-64, 65+
This meta-analysis examined 6 randomized controlled trials (255 participants) examined if a plant-based diet (vegetarian or vegan) improves glycemic control compared to a conventional diabetes diet (which was different for each study) in the context of type 2 diabetes.
A vegetarian or vegan diet showed a significantly larger reduction in HbA1c (-0.39% between-group difference) and a non-significant larger reduction in fasting blood glucose (-0.36 mM between-group difference) than the comparator diabetes diet.
The researchers conclude that vegetarian or vegan diets may be useful for improved glycemic control in type 2 diabetes.
