Nutrition is central to preventing and managing gastrointestinal (GI) and liver diseases, yet dietary advice remains generic. Conditions such as IBD, IBS, MASLD, celiac disease, and GERD are strongly diet‑influenced. Conventional personalized nutrition fails to account for metabolic, genetic, and microbiome variability. AI integrates genomics, microbiome, metabolic markers, and real‑time dietary tracking to generate individualized recommendations. AI tools are advancing dietary assessment, condition‑specific optimization, and continuous monitoring via wearables and natural language processing. Challenges remain: lack of standardized protocols, bias, privacy concerns, limited clinical validation, and underrepresentation of nutrition in AI applications. Opportunities include federated learning, real‑world validation, and regulatory frameworks. This narrative review synthesizes literature from 2015–2025.Nutrition is central to preventing and managing gastrointestinal (GI) and liver diseases, yet dietary advice remains generic.

A new study in Nature by researchers at Baylor College of Medicine answers a long-standing question about astrocytes, star-shaped cells that are the most abundant support cells in the brain and spinal cord. Scientists have long wondered whether astrocytes come in specialized types that do different jobs. Using a new genetic tool, the team showed that they do: distinct astrocyte subtypes help build connections between nerve cells, shape brain circuits involved in learning and memory and aid recovery after stroke.

People experiencing technology-facilitated abuse, such as spyware on a phone, an ex tracking their location, or an abuser controlling their accounts, may encounter or turn to AI chatbots for help. A new study led by researchers at NYU Tandon School of Engineering finds that the advice those systems provide is frequently inaccurate, incomplete, or potentially unsafe to follow.
