Abstract

Nowadays, metabolic health problems such as obesity or diabetes are more and more common in people. Many people hope to improve or prevent these metabolic health problems by replacing sugar-sweetened beverage (SSB) and sugar with Diet drink and non-nutritive sweeteners (NNS). With the increasing consumption of diet drink and NNS, more and more researchers have begun to study their effects on metabolic problems. Some prospective studies suggest that consumption of NNS may affect the balance of gut microbes and thus affect metabolic health problems, also possibly lead to obesity or glucose metabolism problems. This paper reviews relevant studies and concludes that NNS does affect intestinal microbial balance in animal and cell experiments, but further research is needed in other directions. To study the mechanism of NNS affecting metabolic health, the experimental conditions were needed and randomized trials need to added. This will be the direction of further efforts.
