National Food Intake Assessment: Technologies to Advance Traditional Methods

Abstract

National dietary surveillance produces dietary intake data used for various purposes including development and evaluation of national policies in food and nutrition. Since 2000, What We Eat in America, the dietary component of the National Health and Nutrition Examination Survey, has collected dietary data and reported on the dietary intake of the US population. Continual innovations are required to improve methods of data collection, quality, and relevance. This review article evaluates the strengths and limitations of current and newer methods in national dietary data collection, underscoring the use of technology and emerging technology applications. We offer four objectives for national dietary surveillance that serve as guiding principles in the evaluation. Moving forward, national dietary surveillance must take advantage of new technologies for their potential in enhanced efficiency and objectivity in data operations while continuing to collect accurate dietary information that is standardized, validated, and publicly transparent.

Role of metabolomics in the delivery of precision nutrition

“…The limitations associated with current methods for assessment of food intake are well documented in the literature [ [11] , [12] , [13] , [14] ]. Metabolomics derived biomarkers of food intake have potential to address some of these limitations.…”
