Abstract
Substantial dietary underreporting questions the validity of dietary measurements of energy intake (El). The present study compares the value of a 7-day prospective dietary record (7dDR) with a computer program-based diet history (DH). 7dDR and DH were performed in 50 non-obese subjects (33 females, 17 males, mean age 26.1 years, BMI 18.9-29.6 kg/ m2) using total energy expenditure (EE = sum of resting metabolic rate as measured by indirect calorimetry plus energy expenditure derived from an activity protocol) as standard for the validity of data on EL El was 2,206 (728-3,646) kcal/day for 7dDR and 2,398 (566-4,764) kcal/day for DH. There was an association between El for 7dDR and El for DH (r = 0.6, pKeywords
