Nutrigenomics may provide the nutritional sciences with a molecular basis for positioning nutritional bioactives, functional foods, and designer diets to preemptively offset chronic disease. The preemptive model of nutrition consists of multiple interdependent parts that can be simplified into a number of principle axes. The science axis links nutrient-gene interaction with a health or disease state; the clinical axis ties in the modifying effects of genetic polymorphisms to biomarkers of clinical effect; and the information axis links empowered consumers to authoritative information and counseling resources. Despite the complexity of the model and the nascent state of the nutrigenomic sciences, there are emerging examples of how the model might be reduced to practice, such as the use of n-3 polyunsaturated fatty acids (PUFAs) in the dietary management of proinflammatory states. Although tightly controlled small-scale clinical studies with n-3 PUFAs are encouraging, what is needed are large-scale studies in free-living populations to broadly validate the molecular model of preemptive nutrition. With the expansion of research and the development of shared nutrigenomic databases, it may well become possible to define and track the influence of targeted nutrition on inflammation and the aging process.
营养基因组学可为营养科学提供分子基础,用于定位营养生物活性物质、功能食品和定制饮食,以预防性地对抗慢性病。营养预防模型由多个相互依存的部分组成,可简化为若干主要方面。科学方面将营养素与基因的相互作用与健康或疾病状态联系起来;临床方面将基因多态性的调节作用与临床效应的生物标志物联系起来;信息方面则将获得信息的消费者与权威信息及咨询资源联系起来。尽管该模型很复杂,且营养基因组学科学尚处于起步阶段,但已有一些该模型如何付诸实践的新例子,比如在炎症状态的饮食管理中使用n-3多不饱和脂肪酸(PUFA)。虽然对n-3多不饱和脂肪酸进行的严格控制的小规模临床研究令人鼓舞,但仍需要在自由生活的人群中开展大规模研究,以广泛验证营养预防的分子模型。随着研究的扩展和共享营养基因组数据库的开发,很有可能定义并追踪目标营养对炎症和衰老过程的影响。
