a review of the relationship between dietary glycemic index and glycemic load and type 2 diabetes

background: in recent decades, studies on type 2 diabetes (t2d), have adopted a new approach to the field of a more complete collection of variables related to the lifestyles and diet of people. diet is an important factor in increasing the rate of t2d among individuals. considering the consumption of a high-carbohydrate diet, little attention has been paid to the type of carbohydrates consumed in the incidence of t2d. the present study aimed to review the literature on the relationship between the glycemic index (gi), the glycemic load, (gl) and t2d, it also targets at evaluating and comparing the results of similar studies in other countries methods: .using search engines, including pubmed, science direct, embase and scopus, and key words such as gi, gl, diabetes; articles with cross-sectional, clinical trial, prospective and retrospective cohort designs between 2000 to 2016 were selected. moreover, non-english language articles were not investigate. results: the results of these studies showed that a diet containing low gi and gl has beneficial effects on the metabolism of glucose in the body and is also considered as a factor to protect the body against t2d and its complications. monitoring eating habits of people with t2d can have beneficial effects on t2d and its associated risk factors.
