metabolomics

Aging, whether you consider it a “natural” biologic process or a disease, is increasingly the subject of scientific investigation that goes beyond epidemiologic studies. Or how diseases impact longevity. Some of the most exciting work comes from studying our metabolism and mapping those changes to specific diseases.
