Pharmacological and nutritional interventions targeting postprandial glycemia have proved effective in reducing the risk for type 2 diabetes and its cardiovascular complications. are limited or not cost-effective, such as type 1 diabetes, gestational diabetes, and impaired glucose tolerance. Consequently, preload-based nutritional strategies, either only or in combination with pharmacological treatments, may offer PF-4989216 a simple, effective, safe, and inexpensive tool for the prevention and management of postprandial hyperglycemia. Here, we survey these novel physiological insights and their restorative implications for individuals with diabetes mellitus and modified glucose tolerance. 0.05 using combined Wilcoxon signed-rank test for within-group difference between Preload and Control. The number of experimental studies in support to the medical application of this promising nutritional approach is rapidly growing. However, gathering all available evidence is demanding given the different keywords used by different organizations to define related diet strategies [e.g., protein/extra fat/nutrient premeal usage (26, 27) or preload (19, 23, 28C30), food/meal/nutrient sequence (31, 32) or order (33)]. An additional degree of difficulty in the interpretation and assessment of different results is made by the heterogeneity of research designs. Actually, the result of preload-based dietary interventions on postprandial glycemia shows up influenced by different variables mainly, such as for example preload structure, size, and timing of ingestion, check food stimulus, and specific blood sugar tolerance position (20) (Shape 1B). Herein, we review the obtainable evidence for the severe and chronic aftereffect of proteins and extra fat preloads on postprandial glycemia through the entire whole spectral range of blood sugar tolerance, from diabetics to prediabetic and healthful individuals (Desk 1), PF-4989216 the underpinning physiological systems, as well as the potential restorative relevance in various medical settings.
