Function of nutraceuticals in the intestinal modulation of animals with non-alcoholic steatohepatitis (NASH): a systematic review: a systematic review

Recent studies have observed the role of intestinal microbiota in the pathogenesis of non-alcoholic steatosis (NASH) and described the relationship between alterations in microbiota (called dysbiosis) with inadequate dietary practices and obesity. Through systematic synthesis this review aims to establish which nutraceuticals can be used in the intestinal modulation of animal models with NASH. Based on the search of MeSH and Decs descriptors, searches were performed on the PubMed, Web of Science and LILACS database using the keywords "Microbiota"; "Gastrointestinal Microbioma"; "Disbiosis"; "Bacterial Translocation"; "Non-alcoholic fatty liver disease"; "NAFLD", "Nutraceuticals" and "Dietetic Supplements". After the methodological screening, seven studies were included. A total of 246 male Sprangue Dawley rats with a mean age of four to eight weeks were evaluated. More than half of the studies (57.1%) used probiotics as nutraceuticals, 28.7% of the researches used tomato products and 14.3% used symbiotics. The results suggest positive effects of probiotics, tomato products and symbiotics in the composition and functions of microorganisms resident in the intestines of animals with NASH, micro according to different mechanisms. Modulation of intestinal microbiota may contribute to minimize the development and progression of NASH.
