From Human Genome and Gut Microbiome to Personalized Cancer Nutrition

摘要

In attempts to improve the quality of life for both healthy and diseased patients,dietary and lifestyle guidelines have been formulated by numerous organizations.However,dietary and lifestyle changes are often insufficient to prevent or cure diseases.Of note,the development of cancer has been shown to be closely related to an individual’s dietary and xenobiotic intake.Interestingly,studies have shown that different people have different reactions to the same dietary interventions.The development of genomic and gut microbiome technologies has started to illuminate internal causes of many of the above phenomena.Variations in the genome affect an individual’s metabolism and the bioavailability of nutrients.Variations in the bacterial colonization lead to different functional potentials for the microbe,differences in metabolite production and modulation of the host’s metabolism.Quantifying and incorporating these factors into a comprehensive individualized nutrition plan may enable cancer patients to receive rational and effective nutritional treatment.
