Diabetes - Dietary Interventions

Toward improved management of NIDDM: A randomized, controlled, pilot intervention using a lowfat, vegetarian diet.

OBJECTIVE:To investigate whether glycemic and lipid control in patients with non-insulin-dependent diabetes (NIDDM) can be significantly improved using a low-fat, vegetarian (vegan) diet in the absence of recommendations regarding exercise or other lifestyle changes. METHODS:Eleven subjects with NIDDM recruited from the Georgetown University Medical Center or the local community were randomly assigned to a low-fat vegan diet (seven subjects) or a conventional low-fat diet (four subjects). Two additional subjects assigned to the control group failed to complete the study.

Favorable impact of a vegan diet with exercise on hemorheology: implications for control of diabetic neuropathy.

A little-noticed clinical report indicates that a low-fat, whole-food vegan diet, coupled with daily walking exercise, leads to rapid remission of neuropathic pain in the majority of type 2 diabetics expressing this complication. Concurrent marked improvements in glycemic control presumably contribute to this benefit, but are unlikely to be solely responsible. Consideration should be given to the possibility that improved blood rheology - decreased blood viscosity and increased blood filterability - plays a prominent role in mediating this effect.

Position of the American Dietetic Association and Dietitians of Canada: vegetarian diets.

It is the position of the American Dietetic Association and Dietitians of Canada that appropriately planned vegetarian diets are healthful, nutritionally adequate, and provide health benefits in the prevention and treatment of certain diseases. Approximately 2.5% of adults in the United States and 4% of adults in Canada follow vegetarian diets. A vegetarian diet is defined as one that does not include meat, fish, or fowl. Interest in vegetarianism appears to be increasing, with many restaurants and college foodservices offering vegetarian meals routinely.

A low-fat vegan diet and a conventional diabetes diet in the treatment of type 2 diabetes: a randomized, controlled, 74-wk clinical trial.

BACKGROUND:Low-fat vegetarian and vegan diets are associated with weight loss, increased insulin sensitivity, and improved cardiovascular health. OBJECTIVE:We compared the effects of a low-fat vegan diet and conventional diabetes diet recommendations on glycemia, weight, and plasma lipids. DESIGN:Free-living individuals with type 2 diabetes were randomly assigned to a low-fat vegan diet (n = 49) or a diet following 2003 American Diabetes Association guidelines (conventional, n = 50) for 74 wk.

Vegetarian and vegan diets in type 2 diabetes management.

Vegetarian and vegan diets offer significant benefits for diabetes management. In observational studies, individuals following vegetarian diets are about half as likely to develop diabetes, compared with non-vegetarians. In clinical trials in individuals with type 2 diabetes, low-fat vegan diets improve glycemic control to a greater extent than conventional diabetes diets.

A plant-based diet for type 2 diabetes: scientific support and practical strategies

PURPOSE: The purpose of this review is to provide educators with the knowledge and tools to utilize plant-based nutrition education as an intervention for type 2 diabetes. Scientific support for the efficacy, acceptability, and nutritional adequacy of a plant-based diet for people with type 2 diabetes is presented, and practical considerations such as medication adjustment and risk of hypoglycemia are reviewed. CONCLUSIONS: Plant-based meal planning is an acceptable and effective strategy that educators can use to improve diabetes management and reduce risk of complications.

Usefulness of vegetarian and vegan diets for treating type 2 diabetes

Significant benefits for diabetes prevention and management have been observed with vegetarian and especially vegan diets. This article reviews observational studies and intervention trials on such diets, and discusses their efficacy, nutritional adequacy, acceptability, and sustainability. Research to date has demonstrated that a low-fat, plant-based nutritional approach improves control of weight, glycemia, and cardiovascular risk.
