“…This probably shows that on collect days the parents of the subjects gave a deliberately or non-deliberately distorted or wrong estimation of the quantities consumed. This type of problem has also been noted by several authors, and the differences have been attributed partly to the increased number of tasks to be per formed when food collections were made and also to a guilty feeling about wasting food which went into the collection jar [9], Analysis of food composites resulted in sig nificant lower values in both boys and girls for energy, protein, and fat than the calculated values from records of the corresponding days. In contrast, the analytical values of car bohydrates were higher than those of the cor responding collect days.…”

Daily energy, protein, fat, carbohydrate, zinc, and copper intakes of 47 healthy 5- to 9-year-old children living in Duisburg, an industrial area of North Rhine-Westphalia, and consuming self-selected diets were calculated using a 4-day weighed dietary records and food composition values. In addition, the parents of the subjects also collected a 24-hour food composite on 2 of the recording days for analysis of the nutrients. This allowed us to compare the calculated value of the nutrients on days when only dietary records were made with those on which also duplicate samples were collected. Daily analyzed intakes were also compared with those calculated from the recording days. Zinc and copper were estimated by atomic absorption spectrometry. The results show that there were reductions in the intake of all nutrients on days when duplicate samples were also collected as compared with the days when only dietary records were made. Median daily calculated intakes for all children on the 4 record days were: energy 1,578 kcal, protein 46.5 g, fat 67.3, carbohydrates 174.7 g, zinc 5.3 mg, and copper 1.0 mg. The median analyzed intakes were: energy 1,367.7 kcal, protein 37.1 g, fat 49.1, carbohydrates 178.7 g, zinc 5.3 mg, and copper 0.7 mg. The use of the duplicate diet method has shown that a 4-day recording period gives an overestimation of the nutrient intake. The calculated and the analyzed zinc intakes did not meet the recommended levels of the Deutsche Gesellschaft für Ernährung. The median copper intakes were in the lower range of the levels recommended by the Deutsche Gesellschaft für Ernährung.

“…Pilot testing of these duplicate diet methodologies, however, found laboratory-analyzed caloric contents of collected foods that were on average 12% to 16% lower than energy intake estimates from detailed food records and calculated energy expenditures (Thomas et al, 1997). Biases in the range of 6% to 25% have been reported by other researchers (Kim et al, 1984;Stockley, 1985;Bro et al, 1990). It is likely that similar bias estimates are applicable to the intake measurements in this study.…”

A National Human Exposure Assessment Survey ( NHEXAS) field study was performed in U.S. Environmental Protection Agency (EPA) Region V, providing population-based exposure distribution data for selected elements in several personal, environmental, and biological media. Population distributions are reported for the 11 elements that were measured in water and dietary samples. Dietary intakes and home tap water concentrations of lead, arsenic, and cadmium were further examined for intermedia associations, for differences between dietary exposure for adults and children, and to estimate the proportion of the population above health-based reference values (dietary) or regulatory action levels or maximum contaminant levels (water). Water lead and arsenic concentrations were significantly associated with dietary intake. Intake of all elements was higher from solid foods than from liquid foods (including drinking water). Dietary intakes of Pb, As, and Cd were greater than those calculated for intake from home tap water or inhalation on a g /day basis. Median dietary intakes for the Region V population for Pb, As, and Cd were 0.10, 0.13, and 0.19 g / kg bw/day, respectively. While Pb, As, and Cd concentrations in the foods consumed by 0 to 6-year-old children were similar to or lower than those for adults, dietary intakes calculated on a body weight basis were 1.5 to 2.5 times higher for young children. Intrapersonal intake differences accounted for most of the variance in short-term (daily) dietary intakes for Pb and As, while interpersonal differences accounted for more of the intake variance for Cd. Only small percentages of the population exceeded health-based intake reference values or concentrations equal to regulatory levels in water for Pb, As, and Cd.

“…methods are available to assess food intake (Dwyer, 1994). While prospective methods are generally preferable for they are less subject to forgetfulness, they may inadvertently stimulate a greater consciousness about intake or otherwise lead the subject to alter intakes during the recording periods (Kim et al, 1984). In this study we collected duplicate portions of food eaten by cadets.…”

Food composition tables (FCT) were validated against chemical analysis (CA) to assess energy, carbohydrate, lipid, protein and fibre content of the food consumed by Italian Army cadets. The absolute difference between FCT and CA in 2 separate weeks was < or = 0.7% for energy, < or = 4.1% for carbohydrates, < or = 2.9% for lipids, < or = 6.2% for proteins and < or = 31.6% for fibre. It is concluded that FCT can be used to assess energy, carbohydrate, lipid and protein but not fibre intake in this military community.
