Overview
With the aging of population and the change of lifestyle, the prevalence of prediabetes is increasing year by year. Nutritional factors are one of the important environmental factors in the occurrence and development of abnormal glucose metabolism. The medical nutritional treatment of diabetes is recommended as the cornerstone of diabetes treatment by various guidelines. With the development of nutrigenomics, it has been found that genes related to the absorption, metabolism, distribution and excretion of various nutrients are related to diabetes. This study intends to conduct precision nutrition intervention for prediabetic patients based on nutritional genes, and evaluate the effectiveness and safety of these nutritional interventions.
