Artificial sweeteners have emerged as popular alternatives to traditional sweeteners, driven by the growing concern over sugar consumption and its associated rise in obesity and metabolic disorders. Despite their widespread use, the safety and health implications of artificial sweeteners remain a topic of debate, with conflicting evidence contributing to uncertainty about their long-term effects. This review synthesizes current scientific evidence regarding the impact of artificial sweeteners on gut microbiota and gastrointestinal health.

Background: Artificial sweeteners (AS) have been widely utilized in the food, beverage, and pharmaceutical industries for decades. While numerous publications have suggested a potential link between AS and diseases, particularly cancer, controversy still surrounds this issue. This study aims to investigate the association between AS consumption and cancer risk.

Prenatal alcohol exposure (PAE) is associated with long-term neurodevelopmental deficits resulting in impaired executive functioning and motor control. Intriguingly, PAE has been linked with an increased risk of transient systemic hypoxia-ischemia (TSHI), which alone results in suboptimal fetal growth and neurodevelopmental consequences. Here, using two translationally relevant preclinical models, we investigated the short-term and lasting effects of PAE and TSHI on the morphology of the medial prefrontal cortex (mPFC), a region important in executive function, and tested whether PAE interacts with TSHI to produce a distinct pattern of injury relative to either condition alone.

To investigate the effects of metallothionein (MT)-1/2 gene knockout on the taste preference and the conditioned taste aversion (CTA), we performed an experiment comparing the behavior of wild type (WT) mice and MT-1/2 null (KO) mice. The taste preference ratio of saccharin solutions (0.1 or 0.

C57BL/6 (B6) mice learn to prefer glucose or sucrose to initially isopreferred or even more preferred nonnutritive sweeteners due to the postoral appetite stimulating (appetition) actions of glucose. Recent evidence indicates that specific duodenal neuropod cells transmit the glucose appetition signal to the brain via glutamatergic synaptic connections with vagal afferents. The present study found that intraperitoneal pretreatment with a glutamatergic receptor antagonist cocktail (kynurenic acid (KA)/D-2-amino-3-phosphonopentanoic acid (AP3)) in B6 mice did not block the expression of their learned preference for 8% glucose solution over an initially-preferred 0.
