Metabolites are the intermediates and products of metabolism. The term ''metabolite'' is usually restricted to small molecules.

Study finds age and body composition may explain gut bacteria differences between milk drinkers

A study of 265 adults suggests that gut bacteria differences between cow's milk and plant-based drink consumers may reflect individual characteristics rather than milk choice.

High-fiber diet beats metformin for blood sugar and weight in trial

High-fiber diet improves blood sugar and weight more than metformin in a small diabetes trial.

Cranberry juice doesn’t affect every woman the same way

Cranberry juice's effectiveness against UTIs varies among women due to metabolic differences, impacting urinary anti-adhesion activity and pathogen response.

Eating walnuts daily may boost mood and shift serotonin-related metabolism

Daily walnuts improve mood and alter serotonin-related metabolites in young adults.

Gut bacterial metabolite worsens brain damage after stroke, study finds

Researchers at LMU have discovered how a metabolite produced by gut bacteria can influence brain damage after stroke.

Esophageal cancer leaves a distinct metabolic signature in the gut

The study uncovers gut microbial and metabolic signatures in esophageal cancer, emphasizing lipid dysregulation and its potential role in disease progression.

Intestinal enzyme links microbial metabolism to MASH progression

Metabolic dysfunction-associated steatohepatitis (MASH) is often viewed through the lens of hepatic lipid accumulation, inflammation and fibrosis. A new study published in eGastroenterology shifts attention upstream, identifying intestinal neutral ceramidase as a gut-derived driver of MASH progression through its effects on microbial metabolism, epithelial signalling and intestinal barrier function.

From espresso to filter coffee, brewing may shape what reaches your gut

A focused narrative review traces how caffeine, chlorogenic acids, and coffee fibers move through the gut and interact with microbes. The authors identify plausible links between the microbiome and liver health, but human studies have not shown that microbiome changes cause coffee’s reported metabolic benefits.

Blood markers linked to healthy eating may reflect more than food choices

Researchers analyzed dietary data from 204,938 UK Biobank participants and identified blood protein and metabolite profiles associated with adherence to the EAT-Lancet diet. These profiles showed stronger links to several health outcomes and modeled life expectancy than the diet score, but the observational study cannot establish that the diet caused those differences.

Could the Mediterranean diet protect the brain through the gut?

A narrative review finds that the Mediterranean diet may support brain health through gut microbiome, immune, metabolic, and barrier-related pathways, but direct human evidence that microbiome remodeling mediates neuroprotection remains limited. The proposed mechanisms involve microbial metabolites, reduced inflammatory signaling, stronger intestinal and blood-brain barrier function, and possible effects on processes linked to Alzheimer’s and Parkinson’s diseases.

Children who ate healthier plant foods had slightly lower blood pressure later

Researchers followed 3,990 Dutch children for an average of 1.6 years and found that higher healthful plant-based diet scores were associated with modestly lower blood pressure and total cholesterol. Children with higher unhealthful plant-based diet scores had lower estimated food costs and distinct metabolite profiles, while healthful scores showed no clear cost association.

Regular exercisers show distinct metabolic and immune signatures in blood

Researchers compared blood samples from 40 regular exercisers and 46 sedentary adults and found differences in metabolites, blood chemistry, and immune cell gene activity. The patterns suggested greater fatty acid use and altered immune signaling among exercisers, but the study could not establish that exercise caused these differences.

Scientists discover metabolite fueling aggressive brain tumor growth

Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from scientists at Children’s Medical Center Research Institute at UT Southwestern (CRI) published in Cell.

Shatavari may affect more than hormones, and the gut could help explain why

A review in Nutrients examined how bioactive compounds in Asparagus racemosus (Shatavari) may influence cognitive health through the microbiota-gut-brain axis, estrogen-related signaling, neuroinflammation, oxidative stress, and neurotransmitter regulation. Evidence from computational, cellular, animal, and limited human studies suggests several plausible biological pathways, but key questions remain about bioavailability, brain exposure, dosing, and clinical efficacy.

Cannabis-derived nanovesicles showed early antitumor potential in mice

Researchers developed a Cannabis sativa hairy root culture system that produced stable plant-derived nanovesicles capable of promoting dendritic cell maturation and activating T-cell responses through TLR2- and TLR4-associated signaling. Oral administration also restored selected immune responses in immunosuppressed mice and suppressed tumor growth in an E.G7 lymphoma model, providing preliminary evidence for their immunomodulatory and antitumor potential.

What children eat may leave a measurable signature in their blood

Researchers analyzed 236 blood metabolites in 421 children to examine metabolic signatures associated with three dietary patterns characterized by core foods, animal protein sources, or poor-quality fats and sugars. The results identified distinct, biologically plausible metabolite patterns across dietary exposures, although most individual associations did not survive multiple-testing correction and require validation in independent cohorts.

Vitamin A derivative prevents immune cell exhaustion in brain tumors

Immune cells can become exhausted after prolonged exposure to cancer, gradually losing their ability to attack tumor cells.

Could one amino acid help explain why men tend to live shorter lives?

A UK Biobank cohort and Mendelian randomization study involving 272,475 participants linked higher circulating tyrosine with greater all-cause mortality and genetically predicted higher tyrosine with shorter lifespan. After accounting for phenylalanine, the relationship with shorter lifespan was clearest in men, while findings in women were less consistent, suggesting a potential sex-specific role for tyrosine in longevity.

Gut bacterial metabolite linked to inflammation in liver disease

Researchers have identified a link between specific activities in gut bacteria and the liver disease PSC.

The obesity-microbiome story is more complicated than ‘good’ and ‘bad’ bacteria

This review finds that obesity is linked to reciprocal interactions between diet, the gut microbiome, microbial metabolites, and host metabolic pathways that influence appetite, insulin sensitivity, inflammation, and energy balance across the lifespan. It highlights diet as a particularly tractable way to influence this system, while emphasizing that microbiome changes associated with GLP-1 therapies remain difficult to separate from weight loss and that functional multi-omics approaches may help enable more personalized interventions.
