The relationship between gut microbiota and diet and nutrition related diseases / 中华预防医学杂志

ABSTRACT

The human gastro-intestinal tract is not only the habitat of gut microbiota, but also the main place that the body gets available nutrients. Therefore, the gut microbiota of human can be inseparable associated with the human nutrition. The common technologies used among gut microbiota research included metageonomic, metatranscriptomics, metaproteomics, and metabolomics. The research of gut microbiota based on above omics methods confirmed that diets were the main factors influencing the composition and expression of gut microbiota. The proportion, quantity, stable state, and metabolic changes of gut microbiota were closely related to obesity, diabetes mellitus, cardiovascular disease, and other nutritional-related diseases. Reasonable dietary intervention can adjust the disorders of gut microbiota, which can achieve prevention and treatment of obesity, diabetes, cardiovascular diseases, and other nutritional-related diseases. Although the single omics methods can be used to study the problems of some aspects of gut microbiota, the combination of multi-omics is needed to achieve the above objectives.
