Effects of Dietary Fiber from Brown Algae on Energy Intake and Body Weight

Abstract

In recent years, brown algae dietary fiber is safe and nontoxic, and has many biological activities, especially in controlling appetite, regulating body weight, regulating blood sugar and lipid metabolism, and regulating intestinal flora, which has attracted the attention of researchers. As a part of diet, dietary fiber is closely related to the change of intestinal microecology. The change of intestinal microecology is closely related to obesity. For example, intestinal flora can improve obesity and related metabolic diseases through its functions in energy harvesting, metabolic signals and inflammatory response. Dietary fiber, as a part of diet, can change the proportion and abundance of intestinal flora, improve inflammatory response, and regulate intestinal hormone and lipid metabolism to improve obesity. However, the recommended intake, types and mechanism of dietary fiber in preventing and treating obesity need further study. In this paper, the effects of dietary fiber from brown algae on energy intake and body weight were discussed, and its potential mechanism was analyzed, which provided scientific basis for the development and application of marine functional products.
