With the development of nutrition science, food science and other related subjects, and people pay more attention to the structure of the diet, dietary fiber has become a hot research topic in recent years. Because of its good physical and chemical properties and physiological function, it is known as the seventh nutrient after protein, fat, carbohydrates, vitamins, minerals and water. In this paper, the definition of dietary fiber, and the classification of dietary fiber are briefly reviewed; the physical and chemical properties of dietary fiber, such as water holding capacity, swelling capacity, rheological properties, etc., and main physiological functions of dietary fiber, such as prevention of cardiovascular diseases, improvement of intestinal flora, antioxidant, scavenging free radicals, etc., are summarized in this paper. The related reports of dietary fiber in dairy products, meat products and functional food are summarized. In view of the existing problems in the research of dietary fiber, the development trend of dietary fiber is prospected, which provides a scientific support for the research and development of new dietary fiber products.
