The study of diet, long plagued by inaccuracies in self reports, is entering a new age of precision with the methods of metabolomics.

Nutrition researchers are beginning to use metabolomics to determine how healthy subjects’ diets are, and even to reveal specific properties of the foods they eat.

Firefighters who didn’t develop obstructive airway disease after the World Trade Center attacks had higher levels of omega-3 fatty acids and other factors that hint at possible protective effects of diet.

A newfound family of metabolites emits green light in response to the blue light of the deep ocean, causing certain sharks to glow.

Researchers seek to untangle the biological mechanisms linking resident microbes to our hearts—and to harness them therapeutically.

Emerging technologies help researchers draw mechanistic links between metabolism and epigenetic modification of DNA.

Out of 25,000 features originally detected by metabolic profiling of E. coli, fewer than 1,000 represent unique metabolites, a study finds.

Obesity-associated microbiome composition can persist after weight loss, affecting the exchange of metabolites between a mouse and its resident bugs, researchers report.

A comprehensive analysis of human urine identifies more than 3,000 metabolites.
