Metabolomics: a tool to aid dietary assessment in nutrition
2017
Brennan, Lorraine
Applications of metabolomics to nutrition is a rapidly growing field with applications ranging from assessment of diet related diseases to understanding molecular mechanisms behind the health benefits of certain diets. The field of dietary biomarkers and in particular food intake biomarkers has expanded rapidly in recent years. Food intake biomarkers are biomarkers that reflect food intake and have the potential to aid dietary assessment. This review focuses on food intake biomarkers and the use of biomarkers for assessment of dietary patterns. In the case of food intake biomarkers two recent examples demonstrating that such biomarkers can actually be used for food intake assessment are highlighted. What makes these examples stand out is the fact that food intake was quantified using urinary biomarkers. For the dietary pattern section, there are two studies of note which developed models that were capable of classifying individuals into dietary patterns. Overall, these studies have made significant progress in the field and the future is promising for food intake biomarkers.
