[Application of nutrigenomics in clinical nutrition].

In the past decade, the focus of nutritional study shifted from epidemiology and physiology to molecular biology. Advanced research strategies and technologies including genomics, transcriptomics, proteomics, metabolomics, and system biology have been gradually applied in clinical nutrition. This article reviews the effects of nutrients on gene expressions, application of modern molecular biology in clinical nutrition, as well as the advances and challenges in recent years..
