Variation in Nutrient Intakes and Required Number of Days for Assessing Usual Nutrient Intake among Different Populations

Abstract

Estimating the usual intake of a population is essential in the process of establishing the protective effects of nutrients against the development of certain diseases and assessing nutrient intake adequacy. A long term assessment of daily intakes is required to assess usual intakes; however, due to the cost and burden of this requirement, most studies employ shorter term assessments. Many limitations exist with dietary assessment tools which can alter the results and conclusions of intake data. This article was aimed to review on the variation of nutrient intakes and required number of days to assess usual nutrient intake status of diverse population groups based on previous publications.
