Nutrigenomics is the report of the background and the importance of the awareness of the genes that affect the foods, and also the foods that affect the genes in human body. It is found that human attempts to link the knowledge of genes and relevant food to associate with various things, or even using the existing evolutionary theories to explain why the evolution emerges and affects human genes by employing food as a method to describe such phenomenon. Besides, Nutrigenomics is currently applied to various genetic abnormality diseases such as diabetes, obesity, cardiovascular disease and cancer etc., by attempting to determine the proper nutrients for the diseases of each individual, as well as attempting to decode the gene of each relevant disease and monitoring the function of such gene, and also finding the genes which are related to the metabolism of active nutrients. All of the mentioned processes will lead to the adjustment of daily recommended intake of nutrients to benefit the disease prevention and also for the patient's best interests. However, the acquired knowledge is still a study which lacks of much important information, causing the development in Nutrigenomics to be still in the research process to collect the full information to be developed for practical use in the future. The nutrigenomics can used to describe the evolution and cancer metabolism also
