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. 

Obesity drives an alteration of the gut microbiome, leading to the secretion of metabolites associated with the development of liver cancer.

Researchers can identify individuals by the unique chemical signatures in their breath, suggesting that exhalations could be used for metabolomic tests.

Once the 2012 Olympics are over, the newly established drug testing lab will be turned into the world’s leading center for metabolic phenotyping.

Untargeted metabolic profiling implicates a new suite of metabolites that may be involved in nerve damage-induced pain.
