[Progress in metabolomics epidemiology]

In recent years, with the rapid development of metabonomic technology and analytic methods, metabolomics epidemiology, as an important branch of systems epidemiology, attracts more attention. Metabolomics epidemiology can better describe the characteristics of exposure, reflect the interaction between environmental factors and genetics, uncover the "black box" of the mechanisms underlying exposure and disease, and identify new biomarkers. This article briefly introduces the definition, methods, and progress of metabolomics epidemiology.
