Inclusion Criteria:
We considered all observational (i.e., cross-sectional or prospective cohort studies) and randomized controlled studies, population: presumably healthy adults in case of observational studies or individuals with T2D ?18 years in case of randomized controlled studies; intervention: vegan or plant-based diet, defined as a dietary pattern that omit all the animal-derived products; comparisons: omnivorous diet, defined as a consumption of all types of foods, including meat, meat products and poultry; outcomes: prevalence or incidence of T2D in case of observational studies, glycemic control and risk factors for diabetes-related complications—Body Mass Index (BMI), waist circumference, lipidemia, blood pressure, microalbuminuria or other parameters of renal function, electrochemical skin conductance or other parameters of nerve function in case of randomized controlled studies.
Exclusion Criteria:
Studies were excluded if there was no vegan intervention (e.g., flexitarian, pesco-vegetarian, lacto-ovo-vegetarian); intervention < 4 week; no omnivorous control; were not conducted in humans or in individuals with T2D (e.g., prediabetes or type 1 diabetes); were conducted in children, adolescents, pregnant or breastfeeding women.
Research Purpose:
The aim of this paper is to conduct a systematic review of all observational and intervention studies that describe the relationship between vegan diets and the risk for type 2 diabetes (T2D), along with its effect on glycemic control and T2D-related complications.
