Abstract

In this study, the authors examined the relative validity and reproducibility of a food frequency questionnaire (EAT5 FFQ) for measuring intake of fiber, and low and high fiber foods, in studies examining diet and gut microbiota in young children. The parents of 5-year old children completed the EAT5 FFQ twice, four weeks apart. A 3-day weighed diet record (WDR) was completed between the appointments. The EAT5 FFQ asked about intakes over the past month using 10 frequency-response options, ranging from ‘not eaten this month’ to an open-ended question. The authors found the EAT5 FFQ had acceptable validity when compared with the 3-day WDR and very good reproducibility when measured over four weeks. The authors conclude that the EAT5 FFQ is an "appropriate dietary assessment tool for investigating intake of nutrients and food groups of relevance to the gut microbiota in studies of young children."
