Study finds nutritional risks in users of GLP-1 drugs

Adults with overweight or obesity taking the new generation of weight loss drugs semaglutide and tirzepatide tend to eat significantly less, leaving them vulnerable to nutritional deficiencies, according to one of the first real-world studies to examine dietary behavior in people using glucagon-like peptide-1 receptor agonists and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) dual agonists RAs (collectively referred to as GLP-1 RAs) with the help of an AI-powered nutritional tracking app.

Targeted diet helps reprogram aggressive neuroblastoma in mice

Researchers highlighted how an arginine- and proline-restricted diet combined with eflornithine reprogrammed MYCN-driven neuroblastoma in mice, pushing tumor cells out of the cell cycle and toward differentiation. The commentary argues that this metabolism-to-translation link could open a new path for testing targeted dietary strategies alongside cancer drugs in future clinical studies.

Cola may quickly lower pH inside orthodontic clear aligners and shift oral bacteria within hours

Researchers found that cola exposure quickly lowered pH and altered the microbiome on the inner surface of clear aligners, with the greatest disruption observed when aligners were removed before drinking and then reinserted. In this small 24-hour study, wearing aligners during exposure appeared less disruptive than removing them, though the authors said the mechanism still needs further study.
