"These studies show that measuring blood levels of TMAO could serve as a powerful tool for predicting future cardiovascular risk, even for those without known risk factors," Hazen said.

"Our goal is not to suggest dietary restrictions of entire food groups. Eggs, meat and other animal products are an integral part of most individuals' diets. Our work shows, however, that when digesting these foods, gut flora can generate a chemical mediator, TMAO, that may contribute to cardiovascular disease," Hazen said.

The study was published in The New England Journal of Medicine.
