Nutritional biomarkers in aging research

Abstract Recent advances indicate that biological aging is a potentially modifiable process. Identifying biomarkers to better characterize the aging process is a research priority and a major public health concern. There is a compelling body of evidence indicating that adherence to healthy dietary patterns and intake of plant-derived bioactive compounds may serve as a potential strategy to preserve body function, slowing the progression of aging and reducing the incidence of age-related diseases. The aim of this chapter is to discuss recent advances in nutritional science, with an emphasis on biomarkers that may predict healthy aging. We summarize the current knowledge concerning potential biomarkers for assessing the causal relationship between aging and nutrition.
