Abstract: Metabolic syndrome is a common pathological basis of critical diseases such as cardiovascular diseases and type 2 diabetes mellitus and is the leading cause of morbidity and mortality. Metabolic disorders of carbohydrates and fats in the diet play a crucial role in the occurrence and development of metabolic syndrome. Numerous studies have focused on the relationship between the adverse effects of high-fat diets and metabolic syndrome. However, little is known about how increased proportion and excessive consumption of refined carbohydrates in the diet promote metabolic syndrome. Currently, there is increasing evidence that dietary carbohydrate is closely related to the development and progression of metabolic syndrome. Therefore, this article aims to review the relationship between carbohydrate intake and metabolic syndrome in order to provide theoretical guidance for developing healthy diets.

Key words: dietary carbohydrates, insulin resistance, metabolic syndrome, type 2 diabetes mellitus
