Oral-Gut Bacteria Linked to Dementia Risk in Parkinson’s Disease

A new study has found that bacteria from the mouth may migrate to the gut and contribute to cognitive decline in people with Parkinson’s disease. Researchers identified harmful microbes and their toxins in the gut of Parkinson’s patients with dementia, suggesting a possible link between oral hygiene, gut health, and neurodegeneration.

Gut Microbiota Transplants May Cause Long-Term Imbalance

New research warns that fecal microbiota transplants (FMT) can lead to long-lasting mismatches in gut regions, causing metabolic and behavioral shifts. While FMT aims to restore gut health by transplanting stool microbes from healthy donors, most microbes come from the colon and may colonize unintended regions like the small intestine.

Study Links Gut Bacteria to MS Risk and Reveals Key Triggers

A new twin study has identified specific gut bacteria that may contribute to the development of multiple sclerosis (MS), the most common inflammatory disease of the central nervous system. By comparing identical twins where only one has MS, researchers reduced confounding genetic and environmental factors and pinpointed 51 bacterial taxa with different abundances.

Acetate and Bacteria Team Up to Burn Fat

A new study reveals that acetate—when paired with specific gut bacteria—can significantly reduce fat and liver mass in both normal and obese mice. Researchers used a supplement called AceCel, which delivers acetate directly to the large intestine, promoting the growth of Bacteroides bacteria.

Gut Microbiome Reveals Chronic Pain Risk, AI Study Finds

New research shows that AI can identify complex regional pain syndrome (CRPS) with over 90% accuracy by analyzing gut microbiome patterns. Despite differences in geography and diet, a shared "microbiome signature" was detected across patients from Israel and Canada.

Western Diet Blocks Gut Microbiome Recovery After Antibiotics

New research shows that a Western-style diet rich in processed foods disrupts the gut microbiome’s ability to recover after antibiotic treatment. In mice, this diet prevented the regrowth of a healthy, diverse microbiome, leaving them more vulnerable to infections like Salmonella.

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 Microbiome Regulates Brain Signals Through the Vagus Nerve

New research provides direct evidence that the gut microbiome communicates with the brain through the vagus nerve. Using germ-free mice, scientists observed significantly reduced vagal nerve activity, which returned to normal after introducing gut bacteria.

Mediterranean Diet Improves Memory via Gut Microbiome Changes

A new study reveals that the Mediterranean diet may enhance cognitive function by altering gut microbiota. Rats fed a Mediterranean-style diet showed distinct bacterial changes linked to better memory, cognitive flexibility, and working memory compared to those on a Western diet.

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.
