Achieving an understanding of the extent of micronutrient adequacy across Europe is a major challenge. The main objective of the present study was to collect and evaluate the prevalence of low micronutrient intakes of different European countries by comparing recent nationally representative dietary survey data from Belgium, Denmark, France, Germany, The Netherlands, Poland, Spain and the United Kingdom. Dietary intake information was evaluated for intakes of Ca, Cu, I, Fe, Mg, K, Se, Zn and the vitamins A, B1, B2, B6, B12, C, D, E and folate. The mean and 5th percentile of the intake distributions were estimated for these countries, for a number of defined sex and age groups. The percentages of those with intakes below the lower reference nutrient intake and the estimated average requirement were calculated. Reference intakes were derived from the UK and Nordic Nutrition Recommendations. The impact of dietary supplement intake as well as inclusion of apparently low energy reporters on the estimates was evaluated. Except for vitamin D, the present study suggests that the current intakes of vitamins from foods lead to low risk of low intakes in all age and sex groups. For current minerals, the study suggests that the risk of low intakes is likely to appear more often in specific age groups. In spite of the limitations of the data, the present study provides valuable new information about micronutrient intakes across Europe and the likelihood of inadequacy country by country.

BackgroundRecent European Union regulation requires setting of maximum amount of micronutrients in dietary supplements or foods taking into account the tolerable upper intake level (ULs) established by scientific risk assessment and population reference intakes.ObjectiveTo collect and evaluate recently available data on intakes of selected vitamins and minerals from conventional foods, food supplements and fortified foods in adults and children. Intake of calcium, copper, iodine, iron, magnesium, phosphorus, selenium, zinc, folic acid, niacin and total vitamin A/retinol, B6, D and E was derived from nationally representative surveys in Denmark, Germany, Finland, Ireland, Italy, the Netherlands, Poland, Spain and the United Kingdom. Intake of high consumers, defined as the 95th percentile of each nutrient, was compared to the UL.ResultsFor most nutrients, adults and children generally consume considerably less than the UL with exceptions being retinol, zinc, iodine, copper and magnesium. The major contributor to intakes for all nutrients and in all countries is from foods in the base diet. The patterns of food supplements and voluntary fortification vary widely among countries with food supplements being responsible for the largest differences in total intakes. In the present study, for those countries with data on fortified foods, fortified foods do not significantly contribute to higher intakes for any nutrient. Total nutrient intake expressed as percentage of the UL is generally higher in children than in adults.ConclusionThe risk of excessive intakes is relatively low for the majority of nutrients with a few exceptions. Children are the most vulnerable group as they are more likely to exhibit high intakes relative to the UL. There is a need to develop improved methods for estimating intakes of micronutrients from fortified foods and food supplements in future dietary surveys.

The Expert Group on the Methodological Approaches and Current Nutritional Recommendations in Children and Adolescents was convened to consider the current situation across Europe with regard to dietary recommendations and reference values for children aged 2 -18 years. Information was obtained for twenty-nine of the thirty-nine countries in Europe and a comprehensive compilation was made of the dietary recommendations current up to September 2002. This report presents a review of the concepts of dietary reference values and a comparison of the methodological approaches used in each country. Attention is drawn to the special considerations that are needed for establishing dietary reference values for children and adolescents. Tables are provided of the current dietary reference values for energy and for the macronutrients, vitamins, minerals, trace elements and water. Brief critiques are included to indicate the scientific foundations of the reference values for children and to offer, where possible, an explanation for the wide differences that exist between countries. This compilation demonstrated that there are considerable disparities in the perceived nutritional requirements of European children and adolescents. Although some of this diversity can be attributed to real physiological and environmental differences, most is due to differences in philosophy about the best methodological approach to use and in the way the theoretical approaches are applied. The report highlights the main methodological and technological issues that will need to be resolved before harmonisation can be fully considered. Solving these issues may help to improve the quality and consistency of dietary reference values across Europe. However, there are also considerable scientific and political barriers that will need to be overcome and the question of whether harmonisation of dietary reference values for children and adolescents is a desirable or achievable goal for Europe requires further consideration.

Background: Recent European Union regulation requires setting of maximum amount of micronutrients in dietary supplements or foods taking into account the tolerable upper intake levels (ULs) established by scientific risk assessment and population reference intakes. Objective: To collect and evaluate recently available data on intakes of selected vitamins and minerals from conventional foods, food supplements and fortified foods in adults and children. Intake of calcium, copper, iodine, iron, magnesium, phosphorus, selenium, zinc, folic acid, niacin and total vitamin A/retinol, B 6 , D and E was derived from nationally representative surveys in Denmark,

In order to examine the effect of energy intake at breakfast on school performance the same morning, the parents of ten parallel school classes of 10-year-old school children at five different schools were persuaded to alter their child's breakfast regimen at home over a period of 4 successive days. A total of 195 families were provided with standard breakfasts with either low or high energy content. Uneaten food was returned and weighed. Individual children were randomly assigned to breakfast alternative on any given day. The teachers who carried out the performance assessments at school were blind to treatment condition. Voluntary physical endurance and the performance of a creativity test were significantly better after a breakfast from which children derived over 20% of their recommended daily energy intake than after a breakfast from which they obtained less than 10% of recommended values. The error rate in an addition task was negatively correlated and the rate of working in a number checking task was positively correlated with individual energy intake from the low-energy breakfast. Significantly fewer children reported feeling bad and self-estimates of hunger sensation were lower during the morning at school after the high energy breakfast. Estimates of energy intake at breakfast based on 24-h dietary recall interviews with the children carried out by telephone at their homes showed good correlation with estimates based on returned food (r = 0.89). Energy intake at breakfast as estimated from returned food had no significant effect on energy intake at school lunch as estimated by dietary recall.

The impact of ingesting various foods on psychological and behavioural functions is a topic of both interest and concern to the general public. In this article, the scientific literature concerning demonstrated cause-and-effect relationships is reviewed, beginning with methodological considerations specific to the quantification of particular behaviours and psychological events. The essential function of food is to satisfy hunger and the need for essential nutrients. The contributions of macronutrients to appetite and satiety are described, as well as their impact on metabolism and energy balance. Functional properties of macronutrient substitutes (high intensity sweeteners, fat replacers) and flavour enhancers are examined in relation to their contribution to hunger, satiety, and energy balance. The effects of foods and individual nutrients on the performance of diverse psychomotor tasks are studied with consideration given to the various validated quantitative tools used to assess behaviour. The effects of food components on activation, sedation, and affective states such as dysphoria are also reviewed, with special attention given to brain function and neuroactive substances such as serotonin and the endorphins. The case of hyperactivity in children is given special emphasis with reference to the potential influence of sugar and food additives. Safety issues related to food constituents and additives are discussed. Finally, a set of criteria is proposed for the evaluation and elaboration of studies in the behavioural and psychological fields, along with suggestions for future research.

Fibres which are soluble or insoluble in water have different physiochemical properties and may therefore be expected to exert different effects on post-ingestive satiety signals. This study compared the effects on short-term (24 h) appetite of two equienergetic high (22 g) fibre breakfasts, an equienergetic low fibre breakfast and a low energy, 'light' breakfast. Psyllium gum (the soluble fibre) and wheat bran (the insoluble fibre) were incorporated into breakfast cereals and consumed at breakfast by sixteen healthy, normal weight males after an overnight fast using a repeated measures, counterbalanced design. Ad libitum energy intake was assessed at a test snack 1.5 h after breakfast, later in the day using food boxes and the following day using food diaries. Motivation to eat and gastrointestinal sensations were tracked for the next 24 h. Hunger ratings showed a trend towards the subjects being less hungry and they consumed significantly less energy at snack time after the high insoluble than after the high soluble fibre breakfast cereal. The soluble fibre breakfast produced a greater suppression of snack intake than the light breakfast, but smaller suppression than the other breakfasts. Interestingly there was a trend toward reduced hunger and voluntary energy consumption following the soluble fibre compared with the insoluble fibre much later in the day (9.5-13.5 h after breakfast) although this was not significant. There was no significant effect of breakfast type on total day energy intake. The results suggest that different types of fibre modulate the timecourse of appetite control and may produce alterations in the experience of motivation and patterns of eating without necessarily effecting total energy intake.

Background/Aims: We aimed at examining the intake of ready-to-eat cereals (RTEC) among adolescents in Crete, Greece, and investigate relationships with health and diet indicators. Methods: A sample of 392 adolescents (183 boys, 209 girls) aged 15 ± 0.4 years, attending high schools of two major counties in Crete, was studied to determine consumption of RTEC using a frequency questionnaire. Anthropometric measurements were performed and blood was drawn for analysis of serum lipoproteins and blood glucose (BG). The physical fitness was assessed with the 20-meter shuttle run test (SRT) and the amount of time watching television was estimated. Nutrient intakes were calculated through 24-hour dietary recalls. Results: 42% (n = 77) of boys and 43% (n = 90) of girls reported consumption of RTEC at least once per week. Approximately 40% of the male and 47% of the female consumers reported eating RTEC only at meals other than breakfast. RTEC consumption was inversely related to the obesity indices and BG levels, and positively related to the SRT (p < 0.05 in all analyses). RTEC consumers had significantly higher intakes of fibre, magnesium, calcium, iron, folate, and vitamins A, B₂ and B₆ (p < 0.05 in all analyses). Conclusion: Our results demonstrated favourable associations between RTEC intake and health and diet indicators in Greek adolescents, with potential implications for improved health status and chronic disease risk reduction.
