Abstract
Objective:
Diets high in whole grains and fiber have been shown to improve glucose metabolism in people with type 2 diabetes. In this article, we review outcomes of randomized, controlled clinical trials exploring the efficacy of different types of diets containing various amounts of fiber in the management of type 2 diabetes.
Methods: We searched PubMed, Medline, and Google Scholar for randomized controlled trials conducted from 1999 to 2009. Search criteria included effect of increased fiber intake, increased whole grain intake, and plant-based diets on glucose homeostasis.
Results: A total of 14 randomized clinical trials were included. Addition of insoluble or soluble fiber to meals, increased consumption of diets rich in whole grains and vegetables, as well as vegan diets improve glucose metabolism and increase insulin sensitivity. The greatest improvement in blood lipids, body weight, and HbA1c occurred in participants on low-fat, plant-based diets.
Conclusions: Increased consumption of vegetables, whole grains, and soluble and insoluble fiber is associated with improved glucose metabolism in both diabetic and non-diabetic individuals. Improvements in insulin sensitivity and glucose homeostasis were more evident in participants following a plant-based diet compared to other commonly used diets. Further randomized clinical trials are needed that focus on the efficacy of plant-based diets and diets rich in whole grains in the prevention and management of diabetes.
El aumento del consumo de vegetales, cereales integrales y fibra soluble e insoluble está asociado con una mejora del metabolismo de la glucosa en pacientes diabéticos e individuos normales. La mejora en la sensibilidad ante la insulina y la homeostasis (equilibro) de la glucosa fue más evidentes en participantes vegetarianos en comparación con las dietas habituales. Se necesitan más estudios adicionales.
