AbstractObjectiveTo validate energy intake (EI) estimated from pre-coded food diaries against energy expenditure (EE) measured with a validated position-and-movement monitor (ActiReg®) in groups of 13-year-old Norwegian schoolchildren.DesignTwo studies were conducted. In study 1 the monitoring period was 4 days; participants recorded their food intake for four consecutive weekdays using food diaries and wore the ActiReg® during the same period. In study 2 the monitoring period was 7 days; participants recorded their food intake for four consecutive days but wore the ActiReg® for a whole week.SettingsParticipants were recruited from grade 8 in a school in and one outside Oslo (Norway).SubjectsForty-one and 31 participants from study 1 and 2, respectively, completed the study.ResultsThe group average EI was 34% lower than the measured EE in study 1 and 24% lower in study 2. The width of the 95% confidence limits of agreement in a Bland–Altman plot for EI and EE varied from -0.2 MJ to 8.2 MJ in study 1 and from -2.3 MJ to 6.9 MJ in study 2. The Pearson correlation coefficients between reported energy intake and expenditure were 0.47 (P = 0.002) in study 1 and 0.74 (P < 0.001) in study 2.ConclusionThe data showed that there was substantial variability in the accuracy of the food diary at the individual level. Furthermore, the diary underestimated the average energy intake. The ability of the food diary to rank individuals according to energy intake was found to be good in one of the studies and moderate in the other.

AbstractA major limitation in nutritional science is the lack of understanding of the nutritional intake of free-living people. There is an inverse relationship between accuracy of reporting of energy intake by all current nutritional methodologies and body weight. In this pilot study we aim to explore whether using a novel lightweight, wearable micro-camera improves the accuracy of dietary intake assessment. Doubly labelled water (DLW) was used to estimate energy expenditure and intake over a 14-d period, over which time participants (n 6) completed a food diary and wore a micro-camera on 2 of the days. Comparisons were made between the estimated energy intake from the reported food diary alone and together with the images from the micro-camera recordings. There was an average daily deficit of 3912 kJ using food diaries to estimate energy intake compared with estimated energy expenditure from DLW (P=0·0118), representing an under-reporting rate of 34 %. Analysis of food diaries alone showed a significant deficit in estimated daily energy intake compared with estimated intake from food diary analysis with images from the micro-camera recordings (405 kJ). Use of the micro-camera images in conjunction with food diaries improves the accuracy of dietary assessment and provides valuable information on macronutrient intake and eating rate. There is a need to develop this recording technique to remove user and assessor bias.

Under-reporting of energy intake (EI) is a well-known problem when measuring dietary intake in free-living populations. The present study aimed at quantifying misreporting by comparing EI estimated from the Danish pre-coded food diary against energy expenditure (EE) measured with a validated position-and-motion instrument (ActiReg®). Further, the influence of recording length on EI:BMR, percentage consumers, the number of meal occasions and recorded food items per meal was examined. A total of 138 Danish volunteers aged 20–59 years wore the ActiReg® and recorded their food intake for 7 consecutive days. Data for 2504 participants from the National Dietary Survey 2000–2 were used for comparison of characteristics and recording length. The results showed that EI was underestimated by 12 % on average compared with EE measured by ActiReg® (PreMed AS, Oslo, Norway). The 95 % limits of agreement for EI and EE were − 6·29 and 3·09 MJ/d. Of the participants, 73 % were classified as acceptable reporters, 26 % as under-reporters and 1 % as over-reporters. EI:BMR was significantly lower on 1–3 consecutive recording days compared with 4–7 recording days (P < 0·03). Percentage consumers of selected food items increased with number of recording days. When recording length was 7 d, the number of reported food items per meal differed between acceptable reporters and under-reporters. EI:BMR was the same on 4 and 7 consecutive recording days. This was, however, a result of under-reporting in the beginning and the end of the 7 d reporting. Together, the results indicate that EI was underestimated at group level and that a 7 d recording is preferable to a 4 d recording period.

1. The energy balance of eleven male and fourteen female adult farmers was measured for 6 d after the harvest, in December-January. Their energy intake was recorded by weighing their food consumption and their energy expenditure was determined using indirect calorimetry.2. Body-weight, expressed as percentage of expected weight-for-height was 91 and 86% of the Inter-departmental Committee on Nutrition for National Development (1963) standard for women and men respectively.3. The staple foods were sorghum (Sorghum vulgare) and millet (Pennisetum typhoïdes); carbohydrates, fat and protein supplied approximately 80, 13 and 12% of the total energy of the diet respectively.4. In the male group, the mean energy intake (9.0 MJ (2148 kcal)) was in good agreement with the average energy output (8.91 MJ (2130 kcal)). By contrast, in the female group, the mean energy expenditure (8.11 MJ (1941 kcal)) exceeded the mean energy intake (6.3 MJ (1515 kcal)) and the deficit was statistically significant.5. This study allows an evaluation of the adequacy of food intake for subjects living in a particular hostile environment, by using their actual energy output instead of current standard values. The energy deficit found for female farmers whose energy intake was similar to that reported in other developing countries emphasizes the need for a better understanding of the regulation of energy balance in such conditions.

OBJECTIVE: The objective was to assess the quantitative agreement between a 4-day food record and a 24-hour dietary recall in young men. METHODS: Thirty-four healthy men aged 18-25 years had their food intake estimated by 4-day food record within one week following 24-hour dietary recall in a cross-sectional study. Resting metabolic rate was assessed by indirect calorimetry and Energy Expenditure was estimated by physical activity records completed simultaneously with food intake records. The validity of food records was determined by direct comparison of Energy Intake and Energy Expenditure (95% confidence interval for Energy Intake/Energy Expenditure). RESULTS: There were good agreements between the measurements of energy and macronutrient intakes by 24-hour dietary recall and 4-day food record at the group level, but not at the individual level. Compared to energy expenditure, about 20% and 9% of participants underreported their Energy Intake by 4-day food record and 24-hour dietary recall, respectively. Over 30% of underreporters of Energy Intake estimated by 24-hour dietary recall underreported Energy Intake estimated by 4-day food record. CONCLUSION: Both diet methods, 24-hour dietary recall and 4-day food record, may be used to collect data at the group level, but not at the individual level. Both methods, however, appear to underestimate Energy Intake. Underreporting may be subject-specific and appears that is more difficult to retrieve valid dietary data from some people than others.

The objective of the present study was to compare energy intake (EI) assessed from a pre-coded food diary (PFD) with energy expenditure (EE) measured by a validated position-and-movement monitor (ActiReg®; PreMed AS, Oslo, Norway) in a group of Norwegian 9-year-olds. Moreover, we examined whether and how under-reporters (UR), identified with ActiReg®, differed from acceptable reporters (AR) according to food intake and BMI. A total of fifty-one 9-year-olds completed PFD and ActiReg®. The present study showed that on average EI was underestimated by 18 % compared with EE measured by ActiReg®. The 95 % confidence limits of agreement in a Bland–Altman plot for EI and EE varied from 1·97 MJ to −4·23 MJ (sd 2) among the girls and from 0·74 MJ to −5·26 MJ (sd 2) among the boys. The Pearson correlation coefficient between EI and EE was 0·28 (P=0·05) for males and females combined. Fifty-seven per cent of the participants were classified as AR, 39 % as UR and 4 % as over-reporters with the PFD. Under-reporting of energy remains a problem with the PFD method used in a group of 9-year-olds, especially among boys. However, UR and AR did not show a systematic misreporting related to macronutrients, unhealthy foods or BMI.

Objective. To investigate children's ability to self-regulate energy intake and to determine whether individual differences in the precision of food intake regulation are related to children's anthropometric measures. We collected information pertaining to parental adiposity and dieting practices, as well as mothers' child-feeding practices. Of special interest was the degree of control imposed by mothers over their children's food intake. Our intent was to explore whether these variables might influence children's regulation of energy intake. Subjects and setting. Seventy-seven 3-5-year-old children who attended a university preschool setting and their parents participated in this experiment. Measurements and main results. Children completed controlled, two-part meals used to estimate their ability to adjust food intake in response to changes in caloric density of the diet. An eating index, reflecting children's precision in the ability to regulate energy intake, was correlated to children's anthropometric measures. These correlations provided evidence for a relation between children's body fat stores and their responsiveness to caloric density cues: Pearson correlation coefficients revealed that children with greater body fat stores were less able to regulate energy intake accurately. The best predictor of children's ability to regulate energy intake was parental control in the feeding situation: mothers who were more controlling of their children's food intake had children who showed less ability to self-regulate energy intake (r = -.67, P &lt; .0001). Conclusions. These findings suggest that the optimal environment for children's development of self-control of energy intake is that in which parents provide healthy food choices but allow children to assume control of how much they consume.

There is currently a lack of research into the energy demands and associated nutritional intakes of elite Gaelic football players during the pre-season period, which is a crucial time of year for physical development. The aim of the current study was to investigate the dietary intake and energy expenditure (EE) of elite Gaelic football players during a typical pre-season week. Over a seven-day period, which included four training days and three rest days, dietary intake (validated self-reported estimated food diary) and EE (Sensewear Pro armband) were recorded in 18 male players from a single elite inter-county Gaelic football team. Average energy intake (EI) (3283 ± 483 kcal) was significantly (p = 0.002) less than average EE (3743 ± 335 kcal), with a mean daily energy deficit of −460 ± 503 kcal. Training days elicited the greatest deficits between intake and expenditure. The mean carbohydrate (CHO) intake was 3.6 ± 0.7 g/kg/day, protein intake was 2.1 ± 0.5 g/kg/day, and fat intake was 1.6 ± 0.2 g/kg/day. These findings indicate that the dietary practices of the sampled players were inadequate to meet EE and CHO recommendations. Training days are of particular concern, with the players not altering energy and CHO intake to encounter increased energy demands. Education on nutritional strategies for elite Gaelic footballers should be considered in relation to training demands to avoid detriments to performance and health.

AbstractTo study, in young growing rats, the consequences of different levels of dietary protein deficiency on food intake, body weight, body composition, and energy balance and to assess the role of FGF21 in the adaptation to a low protein diet. Thirty-six weanling rats were fed diets containing 3%, 5%, 8%, 12%, 15% and 20% protein for three weeks. Body weight, food intake, energy expenditure and metabolic parameters were followed throughout this period. The very low-protein diets (3% and 5%) induced a large decrease in body weight gain and an increase in energy intake relative to body mass. No gain in fat mass was observed because energy expenditure increased in proportion to energy intake. As expected, Fgf21 expression in the liver and plasma FGF21 increased with low-protein diets, but Fgf21 expression in the hypothalamus decreased. Under low protein diets (3% and 5%), the increase in liver Fgf21 and the decrease of Fgf21 in the hypothalamus induced an increase in energy expenditure and the decrease in the satiety signal responsible for hyperphagia. Our results highlight that when dietary protein decreases below 8%, the liver detects the low protein diet and responds by activating synthesis and secretion of FGF21 in order to activate an endocrine signal that induces metabolic adaptation. The hypothalamus, in comparison, responds to protein deficiency when dietary protein decreases below 5%.

AbstractObjectiveInterventions to reduce adolescents’ non-core food intake (i.e. foods high in fat and sugar) could target specific people or specific environments, but the relative importance of environmental contexts v. individual characteristics is unknown.DesignCross-sectional.SettingData from 4d food diaries in the UK National Diet and Nutrition Survey (NDNS) 2008–2012 were analysed. NDNS food items were classified as ‘non-core’ based on fat and sugar cut-off points per 100g of food. Linear multilevel models investigated associations between ‘where’ (home, school, etc.) and ‘with whom’ (parents, friends, etc.) eating contexts and non-core food energy (kcal) per eating occasion (EO), adjusting for variables at the EO (e.g. time of day) and adolescent level (e.g. gender).ParticipantsAdolescents (n 884) aged 11–18 years.ResultsOnly 11 % of variation in non-core energy intake was attributed to differences between adolescents. In adjusted models, non-core food intake was 151 % higher (ratio; 95 % CI) in EO at ‘Eateries’ (2·51; 2·14, 2·95) and 88 % higher at ‘School’ (1·88; 1·65, 2·13) compared with ‘Home’. EO with ‘Friends’ (1·16; CI 1·03, 1·31) and ‘Family & friends’ (1·21; 1·07, 1·37) contained 16–21 % more non-core food compared with eating ‘Alone’. At the individual level, total energy intake and BMI, but not social class, gender or age, were weakly associated with more non-core energy intake.ConclusionsRegardless of individual characteristics, adolescents’ non-core food consumption was higher outside the home, especially at eateries. Targeting specific eating contexts, not individuals, may contribute to more effective public health interventions.

Abstract Objectives The aim of the study was to assess dietary intake of coeliac disease (CD) patients and to determine if they are meeting the dietary reference values for a balanced diet. Subjects/Methods 40 women with CD, aged from 23 to 76 participated in our study. Total daily intake was assessed by a three-day food diary. Resting metabolic rate (RMR) was calculated using Harris-Benedict equation. Considering physical activity level (PAL) 1.4, the recommended total energy expenditure (TEE) value was determined. The data was evaluated with professional evaluation software Prodi and statistically analysed. Results 40 participants returned the food diary. The average energy intake was significantly too low to ensure the meeting of all-day energy needs (p<0.05). The meals contained a recommended proportion of protein, but a statistically significantly higher proportion of fat (p<0.05), lower proportion of carbohydrates and a significantly lower intake of dietary fibre (p<0.05). Regarding macro-, micro- elements and vitamins, there was a significant lack in the intake of calcium and iodine, folic acid, vitamin D and vitamin A (p<0.05), meanwhile iron intake was at the lower limit of the recommended intake, whereas zinc, potassium and vitamin K intake were significantly higher according to the recommended values, but were comparable with the intake of the general population in the Central European area. Conclusion Even in subjects with adequate or low daily energy intake, their meals contained too much fat, too few carbohydrates and dietary fibre as well as inorganic substances. The patients with CD should get regular nutritional monitoring and education on the quality and balance of a gluten-free diet.
