  journal={Current Diabetes Reports},
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. These studies have also shown that carefully planned vegan… 
Vegetarian Diets in the Prevention and Treatment of Type 2 Diabetes
Clinical interventional trials demonstrated that vegetarian diets lead to a greater weight loss and greater reduction in fasting plasma glucose, HbA1c, blood lipids, and hypoglycemic medication than a conventional hypocaloric diet in subjects with type 2 diabetes.
Vegetarian Diets and the Risk of Diabetes
A vegetarian diet characterized by whole plant foods is most beneficial for diabetes prevention and management and may be more beneficial than medication for diabetes management.
A plant-based diet for the prevention and treatment of type 2 diabetes
Multiple potential mechanisms underlie the benefits of a plant-based diet in ameliorating insulin resistance, including promotion of a healthy body weight, increases in fiber and phytonutrients, food-microbiome interactions, and decreases in saturated fat, advanced glycation endproducts, nitrosamines, and heme iron.
Nutrients and Dietary Approaches in Patients with Type 2 Diabetes Mellitus and Cardiovascular Disease: A Narrative Review
The role of different groups of nutrients in patients with T2DM and CVD, as well as dietary approaches that have been associated with better and worse outcomes in those patients are provided.
Alimentação Vegetariana: Abordagem Terapêutica Vegetarian Diet: Therapeutic Approach
The vegetarian diet is beneficial for the prevention and treatment of various diseases, including Cardiovascular Diseases, Type 2 Diabetes, Hypertension, Obesity, Chronic Renal Disease and some types of Cancer.
Body weight regulation and obesity: dietary strategies to improve the metabolic profile.
A growing body of evidence suggests that dietary strategies with the aim to reduce postprandial insulin response and increase fat oxidation, and that tend to restore metabolic flexibility, have a place in the prevention and treatment of obesity and associated metabolic disorders.
Cardio-Metabolic Benefits of Plant-Based Diets
The use of plant-based diets as a means of prevention and treatment of cardio-metabolic disease should be promoted through dietary guidelines and recommendations.
The Impact of a Plant-based Diet on the Prevention and Management of Type 2 Diabetes Mellitus
Results indicate that a plant-based diet is beneficial in the prevention and treatment of diabetes as realized by improved hemoglobin A1c, fasting blood glucose, and even allowing for a reduction or discontinuation of diabetes related medications.


Vegetarian and vegan diets in type 2 diabetes management.
Evidence suggests that reduced intake of saturated fats and high-glycemic-index foods, increased intake of dietary fiber and vegetable protein, and decreased iron stores mediate the influence of plant-based diets on glycemia.
Position of the American Dietetic Association: vegetarian diets.
This article reviews the current data related to key nutrients for vegetarians including protein, n-3 fatty acids, iron, zinc, iodine, calcium, and vitamins D and B-12 and concludes that a vegetarian diet can meet current recommendations for all of these nutrients.
Effects of plant-based diets on plasma lipids.
A low-fat vegan diet and a conventional diabetes diet in the treatment of type 2 diabetes: a randomized, controlled, 74-wk clinical trial.
In an analysis controlling for medication changes, a low-fat vegan diet appeared to improve glycemia and plasma lipids more than did conventional diabetes diet recommendations.
Vegetarian diets and weight status.
The extent to which and by what mechanism(s) a plant-based diet may mediate body weight is reviewed to ascertain.
Position of the American Dietetic Association: health implications of dietary fiber.

Acceptability of a low-fat vegan diet compares favorably to a step II diet in a randomized, controlled trial.
The acceptability of a low-fat vegan diet is high and not demonstrably different from that of a more moderate low- fat diet among well-educated, postmenopausal women in a research environment.
Type of Vegetarian Diet, Body Weight, and Prevalence of Type 2 Diabetes
The 5-unit BMI difference between vegans and nonvegetarians indicates a substantial potential of vegetarianism to protect against obesity and protected against risk of type 2 diabetes after lifestyle characteristics and BMI were taken into account.
