Worldwide, the demand for natural and synthetic sweeteners in the food industry as an alternative to refined sugar is increasing. This has prompted more research to be conducted to estimate its safety and effects on health. The gut microbiome is critical in metabolizing selected sweeteners which might affect overall health. Recently, more studies have evaluated the relationship between sweeteners and the gut microbiome. This review summarizes the current knowledge regarding the role played by the gut microbiome in metabolizing selected sweeteners. It also addresses the influence of the five selected sweeteners and their metabolites on GI cancer-related pathways. Overall, the observed positive effects of sweetener consumption on GI cancer pathways, such as apoptosis and cell cycle arrest, require further investigation in order to understand the underlying mechanism.
