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.

High-quality plant-based diets linked to lower dementia risk

Eating a higher quality plant-based diet is associated with a lower risk of Alzheimer's disease and other related dementias compared to eating a lower quality plant-based diet, according to a study published April 8, 2026, in Neurology, the medical journal of the American Academy of Neurology.

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.

Can diet influence thyroid disease? A major review points to Mediterranean-style eating

This review found that thyroid health depends on more than iodine alone, with selenium, iron, zinc, vitamins, omega-3s, and overall eating patterns all shaping thyroid function and autoimmunity. It also concluded that Mediterranean-style diets are linked to more favorable thyroid outcomes, while unnecessary restrictive diets offer little benefit without a clear medical indication.

Early genetic signals connect diabetes subgroups to heart disease risk

A growing body of research shows that diabetes can be stratified into five different subgroups. Researchers at Lund University have now investigated whether a person's genetic predisposition to different diabetes subgroups can help assess the risk of developing coronary artery disease.

How gut microbes may shape heart attack damage and recovery

This review argues that gut microbes and the metabolites they produce, especially SCFAs and TMAO, may shape how the heart responds to myocardial infarction through epigenetic pathways such as DNA methylation, histone modification, and non-coding RNAs. It also outlines potential intervention routes, including diet, probiotics, postbiotics, and metabolite-targeted therapies, while noting that much of the evidence remains translational and not yet clinically definitive.

Large-scale exposome research shows how multiple factors influence disease risk

For decades, scientists have been carefully unraveling the role of genes in disease by examining how small variations in a person's genetic code can shape lifelong risk of developing common conditions such as cancer, diabetes, or heart disease.
