- The aim of the present study was to examine the body burden of lead (Pb), mercury (Hg), and cadmium (Cd) in blood among Swedish adults and the association between blood levels, diet and other lifestyle factors. The study was based on a subgroup (n = 273) of the national survey Riksmaten 2010-2011 (4-day food records and questionnaire). Lead, Hg, and Cd were measured in whole blood, and Cd additionally in urine, by mass or fluorescence spectrometry methods. The median values (5-95th percentiles) of the metals in blood were as follows: Pb: 13.4 (5.8-28.6) mu g/L, Hg: 1.13 (0.31-3.45) mu g/L, and Cd: 0.19 (0.09-1.08) mu g/L. All three metals increased with increasing age. Lead levels in blood were positively associated with intakes of game and alcohol, Hg was related to fish intake, and blood Cd related to smoking and low iron stores and to a low meat intake. Body burdens of the studied metals were generally below health based reference values, but several individuals had blood Pb levels above the reference point for possible nephrotoxic and developmental neurotoxic effects. As health effects cannot be excluded, individuals with high Pb exposure should aim at decreasing their body burden, both from food and from other exposure routes. (c) 2013 Elsevier Ltd.

- ScopeIn this study, food is suggested as a major source of human exposure to perfluorinated alkyl acids (PFAA). We investigated relations between serum levels of PFAA in adults and diet/lifestyle factors nationwide in Sweden. Methods and resultsIn 2010-2011, adults (18-80 years, N = 270) recorded their diet for 4 days and answered a food frequency questionnaire. PFAA were measured in blood serum as well as v-3 fatty acids in plasma phospholipids as a biomarker for fish consumption. Higher levels of PFAA were associated with male sex, increased age, and higher education. Women reporting full breastfeeding for 12 months had 32-44% lower levels of perfluorooctane sulfonate, perfluorooctanoic acid, and perfluorohexane sulfonate than women who never nursed their infants full-time. Serum perfluorooctane sulfonate, perfluorononanoic acid, perfluorodecanoic acid, and perfluoroundecanoic acid were positively related to n-3 fatty acids in plasma (partial r = 0.19-0.34, p 0.05). ConclusionThe relatively strong correlations between biomarkers of fish consumption and certain PFAA suggest that PFAA exposure should be taken into account in health risk and benefit assessment of fish consumption. Breastfeeding appears to be a major source of elimination of certain PFAA among women, and consequently PFAA exposure of nursed infants could be significant.

- Aims: School lunches are provided free in Sweden, although some children choose not to eat school lunch. The aim of this study was to analyse Swedish children's total energy and nutrient intakes on weekdays by the frequency of school lunch consumption and to analyse energy and nutrient intakes from school lunches by sex. Factors associated with children's school lunch habits were also studied. Methods: Children in grades 2 and 5 (n=1905) completed a food diary (school lunch data available for 1840 children) and the mean energy and nutrient intakes per day and per school lunch were calculated. The children also completed questions on the frequency of school lunch consumption and school lunch habits. Logistic regression was used to assess factors associated with school lunch habits. Results: Children who reported eating school lunch every day had significantly higher energy and absolute nutrient intakes than children reporting eating school lunch less than five times a week, but not standardized for energy. Boys had significantly higher energy and absolute nutrient intakes from school lunches than girls, but not standardized for energy. Younger children and children who liked school lunches had higher odds of eating school lunch every day. Children in grade 5, those with a foreign background and those disliking school lunches had higher odds of omitting the main lunch component. Conclusions: Regular school lunch consumption was associated with a higher total intake for most nutrients, but not a better nutrient density. School lunch habits were associated with age, ethnic background and liking school lunches.

- Background: In Sweden, school meals are served free of charge and Swedish law states that school meals must be nutritious. Nevertheless, data on children's energy and nutrient intake from school meals are scarce.Objective: The aim was to describe the contribution of school meals to Swedish children's nutrient and energy intake during weekdays and compare this to the reference values based on the Nordic Nutrition Recommendations (NNR), which have been adopted as the official Swedish recommendations.Design: A cross-sectional food consumption survey was performed on 1,840 Swedish children attending Grade 2 (mean age 8.6) and Grade 5 (mean age 11.7). The children's nutrient and energy intake was compared to the reference values based on the NNR.Results: The mean intake from school meals of energy, carbohydrates, dietary fiber, polyunsaturated fatty acids (PUFA), and vitamins D and E did not reach the reference values and the intake of saturated fatty acids (SFA) and sodium exceeded the reference values in both age groups (significant differences, all p <= 0.001). Additionally, the pupils in Grade 5 did not reach the reference values for folate, potassium, calcium, magnesium, iron, selenium, and zinc (significant differences, all p <= 0.001). Standardized for energy, dietary fiber, PUFA, and vitamins D and E did not reach the reference values, whereas the reference values for SFA and sodium were exceeded in both age groups (significant differences, all p <= 0.001).Conclusions: The study pointed to some central nutrients in need of improvement as regards school meals in Sweden, namely the quality of fat, dietary fiber, sodium, vitamin D, and iron. Some of these results may be attributed to the children not reporting eating the recommended number of calories, the children omitting some components of the meal, or underreporting, as a consequence of which the reference values for several nutrients were not met.
