Non-nutritive sweeteners are frequently used by people in an effort to reduce their daily caloric consumption, lose weight, and maintain a balanced diet. The safety of eating NNS is not sufficiently supported by scientific evidence. The consumption of NNS, however, may cause symbiosis in the gut macrobiotic and encourage glucose intolerance in healthy people, which may lead to the onset of type 2 diabetes mellitus. Through microRNA-mediated alterations, this series of events may alter the composition of the gut macrobiotic. The relationship between the ingestion of NNS and the emergence of metabolic alterations can be explained by the mechanism by which miRNAs modify the gene expression of various bacterial species.

The utilisation of non-nutritive sweeteners, or non-caloric artificial sweeteners—terms that are used interchangeably—and their potential future application in the food business are covered in this article. The development of metabolic syndrome linked to NNS use is the topic of this review, which is especially concerned with finding the underlying mechanisms that may be to blame. We'll talk about how NNS alters metabolism among other physiological impacts. In this section, we'll focus on the pathogenic processes by which miRNA could be able to mediate the changes in gut macrobiotic composition, the development of T2DM, and the potential function of GPCR-IR crosstalk in the emergence of glucose intolerance and insulin resistance.

Since artificial sweeteners are preferable to sucrose and other sugar substitutes, even though sugar substitutes have been around since the 1880s, usage of them has dramatically expanded during the past 20 years. NNS can be hundreds to thousands of times sweeter than sucrose while having a low calorie value, making them advantageous health tools in attempts to manage caloric intake and support weight loss. With cross-sectional research revealing that 25% of children and 41% of adults take low-calorie sweeteners; this trend has led to NNS becoming a mainstay in the Western diet. Females, obese people, non-Hispanic white people, and people with greater incomes are observed to consume NAS at higher rates.

Despite the FDA has approved a number of sucrose substitutes labelled as Generally Recognized As Safe, it is still rising worry regarding the adverse consequences that may be connected to the use of NNS. Although artificial sweetener use and weight gain have been the subject of numerous epidemiologic studies, it is crucial to take causality into account when interpreting these studies and to account for confounding variables like age, diet, and environment as well as additional stressors that could change macrobiotic composition. The gaps in our understanding of how NNS consumption affects host metabolism highlight how crucial it is to conduct more study to comprehend the mechanistic effects of NNS on the body.

The development of the gut macrobiotic, which is made up of millions of bacteria, viruses, and fungi that coexist symbiotically in the gut, starts at birth. The micro-biota’s makeup and function vary not only from person to person but also over the course of a person's lifetime as a result of external influences including antibiotics, nutrition, and environmental stressors. Regarding the large degree of individual variation in lifestyle and genetics, it is estimated that nutrition accounts for 10% or more of the influence on gut macrobiotic. The specifics are still being explored, but abnormalities in the gut macrobiotic have been linked to the emergence of insulin resistance, obesity, and the metabolic syndrome.

Here, the molecular interaction between the IR and GPCRs through a proposed dimensional G protein partitioning efficacy is the possible mechanism that can link NNS to metabolic alterations. The TIR2/TIR3 demerit receptors would operate as a chemical bridge in this scenario, controlling the communication and signalling between these molecules on the cell surface. A biased TIR2/TIR3 GPCR agonist-induced IR transactivation signalling axis, which is mediated by Neu-1 sialidase activity and the alteration of insulin receptor glycosylation, could be explained by the proposed molecular model.
