          Ultra-Processed Foods Disrupt Infant Gut Health

          A Brazilian study of 728 infants found that ultra-processed foods can harm gut microbiota diversity, with stronger effects in children who were not breastfed. Breastfed infants had higher levels of beneficial Bifidobacterium, while non-breastfed children consuming processed products showed elevated levels of bacteria linked to obesity and gastrointestinal issues.

          Gut Microbiome Shifts Rapidly After Alcohol Use

          A new study shows that combining heavy alcohol use with burn trauma causes severe disruptions in the gut microbiome, leading to inflammation and a weakened gut barrier. Within a day of injury, beneficial bacteria plummet, harmful microbes rise, and levels of butyrate—a key anti-inflammatory compound—drop significantly.

          Gut Microbiome May Hold Key to Treating Sleep Apnea

          A new review highlights growing evidence linking gut health to sleep apnea, suggesting that changes in gut microbiota may influence the severity of sleep-disordered breathing. These microbial imbalances are associated with increased inflammation, leaky gut, and impaired gut-brain communication—all of which may exacerbate obstructive sleep apnea.

          Gut Imbalances in Autism Linked to Brain and Behavior Changes

          New research reveals that gut imbalances in children with autism may influence brain activity and behavior by disrupting the production of key neurotransmitters like serotonin. Scientists found that changes in gut-derived metabolites are linked to differences in brain structure and function in children with autism.

          Oral Bacteria May Help Detect Autism with 81% Accuracy

          A new study has identified a strong link between oral microbiota and autism spectrum disorder (ASD), revealing 11 bacterial species with potential as biomarkers. By analyzing oral samples from children aged 3–6, researchers developed a prediction model that identifies autism with 81% accuracy.

          The microbial ecosystems in our mouths may impact cognitive function as we age, with pathogenic bacteria linked to cognitive decline. Researchers found that beneficial bacteria, such as Neisseria, are associated with improved memory and attention, while harmful bacteria like Porphyromonas correlate with mild cognitive impairment.

          A study of over 133,000 individuals found that consuming processed red meat daily increases dementia risk by up to 13%, while replacing it with alternatives like nuts, legumes, or fish may lower the risk by 20%. Higher processed meat intake was associated with accelerated cognitive aging and increased subjective cognitive decline (SCD).

          Chronic Gut Virus May Play a Role in Alzheimer’s Development

          Researchers have linked chronic intestinal infections caused by cytomegalovirus (HCMV) to a unique subtype of Alzheimer’s disease. The virus may travel from the gut to the brain via the vagus nerve, altering immune responses and contributing to hallmark Alzheimer’s changes like amyloid plaques and tau tangles. While HCMV infection is common and typically harmless, this study found that it may cause chronic brain inflammation in certain individuals.

          Gut Microbes May Have Powered Evolution of Larger Brains

          A new study suggests that gut microbes played a key role in the evolution of larger brains in primates by influencing energy production and usage. Researchers implanted microbes from humans, squirrel monkeys (large-brained species), and macaques (small-brained species) into mice, observing that microbes from larger-brained primates enhanced energy production, while those from smaller-brained primates favored fat storage.
