- BACKGROUND: Breastmilk is the recommended aliment for preterm infants. Milk banks provide donated breastmilk for the neonatal care of preterm infants when mother's own milk is not is available. To avoid pathogen transmission, donated breastmilk is heat-treated according to different procedures before administration. There is varying information on the effect of heat treatment on folate in breastmilk. Sufficient folate intake, however, is essential for normal growth and brain development. This study determined and compared the effects of different heat treatments on breastmilk folate content and pattern of individual folate forms.MATERIALS AND METHODS: Donated Swedish breastmilk samples were heat-treated according to three procedures: two low temperature treatments (57°C, 23 minutes; 62.5°C, 12 minutes) and a rapid high temperature treatment (heating to 73°C in boiling water). The folate content and pattern were determined before and after treatment by high-performance liquid chromatography.RESULTS: The folate content in 38 untreated Swedish breastmilk samples was 150±46 nmol/L. Two different folate vitamers were detected: 5-methyltetrahydrofolate (78±7%) and tetrahydrofolate (22±7%). Heat treatment affected only tetrahydrofolate stability and decreased folate content by 15-24%; however, the effects on folate content did not differ among the investigated heat treatment procedures.CONCLUSIONS: Folate losses during heat treatment of human milk were considered acceptable. Yet, native folate content of heat-treated, non-fortified breastmilk supplied only 25% of the recommended daily intake for preterm infants.

- Background: High intake of protein and low intake of plant-based foods during complementary feeding can contribute to negative long-term health effects.Objectives: To investigate the effects of a protein-reduced, Nordic complementary diet on body composition, growth, biomarkers, and dietary intake, compared with current Swedish dietary recommendations for infants at 12 and 18 mo.Methods: Healthy, term infants (n = 250) were randomly allocated to either a Nordic group (NG) or a conventional group (CG). From 4 to 6 mo, NG participants received repeated exposures of Nordic taste portions. From 6 to 18 mo, NG was supplied with Nordic homemade baby food recipes, protein-reduced baby food products, and parental support. CG followed the current Swedish dietary recommendations. Measurements of body composition, anthropometry, biomarkers, and dietary intake were collected from baseline and at 12 and 18 mo.Results: Of the 250 infants, 82% (n = 206) completed the study. There were no group differences in body composition or growth. In NG, protein intake, blood urea nitrogen and plasma IGF-1 were lower compared to CG at 12 and 18 mo. Infants in NG consumed 42% to 45% more fruits and vegetables compared to CG at 12 and 18 mo, which was reflected in a higher plasma folate at 12 and 18 mo. There were no between-group differences in EI or iron status.Conclusions: Introduction of a predominantly plant-based, protein-reduced diet as part of complementary feeding is feasible and can increase fruit and vegetable intake.This trial was registered at clinicaltrials.gov as NCT02634749.

- Early life is critical for developing healthy eating patterns. This study aimed to investigate the effects of a Nordic, protein-reduced complementary diet (ND) compared to a diet following the current Swedish dietary guidelines on eating patterns and food acceptance. At 4–6 months (mo) of age infants were randomized to a Nordic group (NG, n = 41) or a Conventional group (CG, n = 40), and followed until 18 mo of age. Daily intake of fruits and vegetables (mean ± sd) at 12 mo was significantly higher in the NG compared to the CG: 341 ± 108 g/day vs. 220 ± 76 g/day (p < 0.001), respectively. From 12 to 18 mo, fruit and vegetable intake decreased, but the NG still consumed 32% more compared to the CG: 254 ± 99 g/day vs. 193 ± 67 g/day (p = 0.004). To assess food acceptance, both groups were tested with home exposure meals at 12 and 18 mo. No group differences in acceptance were found. We find that a ND with parental education initiates healthy eating patterns during infancy, but that the exposure meal used in the present study was insufficient to detect major differences in food acceptance. This is most likely explained by the preparation of the meal. Nordic produce offers high environmental sustainability and favorable taste composition to establish healthy food preferences during this sensitive period of early life.

Tidskriftsartikel (refereegranskat)abstract
- Fruits and vegetables are healthy foods but under-consumed among infants and children. Approaches to increase their intake are urgently needed. This study investigated the effects of a systematic introduction of taste portions and a novel protein-reduced complementary diet based on Nordic foods on fruit and vegetable intake, growth and iron status to 9 months of age. Healthy, term infants (n = 250) were recruited and randomly allocated to either a Nordic diet group (NG) or a conventional diet group (CG). Infants were solely breast- or formula-fed at study start. From 4 to 6 months of age, the NG followed a systematic taste portions schedule consisting of home-made purées of Nordic produce for 24 days. Subsequently, the NG was supplied with baby food products and recipes of homemade baby foods based on Nordic ingredients but with reduced protein content compared to the CG. The CG was advised to follow current Swedish recommendations on complementary foods. A total of 232 participants (93%) completed the study. The NG had significantly higher intake of fruits and vegetables than the CG at 9 months of age; 225 ± 109 g/day vs. 156 ± 77 g/day (p < 0.001), respectively. Energy intake was similar, but protein intake was significantly lower in the NG (−26%, p < 0.001) compared to the CG. This lower protein intake was compensated for by higher intake of carbohydrate from fruits and vegetables. No significant group differences in growth or iron status were observed. The intervention resulted in significantly higher consumption of fruits and vegetables in infants introduced to complementary foods based on Nordic ingredients.

- Background: What we eat as infants and children carries long-term consequences. Apart from breastfeeding, the composition of the complementary diet, i.e. the foods given to the infant during the transition from breast milk/infant formula to regular family foods affects the child's future health. A high intake of protein, a low intake of fruits, vegetables and fish and an unfavorable distribution between polyunsaturated and saturated fats are considered to be associate with health risks, e.g. obesity, type 2 diabetes and dyslipidemia later in life.Methods: In a randomized, controlled study from 6 to 18months of age we will compare the currently recommended, Swedish complementary diet to one based on Nordic foods, i.e. an increased intake of fruits, berries, vegetables, tubers, whole-grain and game, and a lower intake of sweets, dairy, meat and poultry, with lower protein content (30% decrease), a higher intake of vegetable fats and fish and a systematic introduction of fruits and greens. The main outcomes are body composition (fat and fat-free mass measured with deuterium), metabolic and inflammatory biomarkers (associated with the amount of body fat) in blood and urine, gut microbiota (thought to be the link between early diet, metabolism and diseases such as obesity and insulin resistance) and blood pressure.We will also measure the participants' energy and nutrient intake, eating behavior and temperament through validated questionnaires, acceptance of new and unfamiliar foods through video-taped test meals and assessment of cognitive development, which we believe can be influenced through an increased intake of fish and milk fats, notably milk fat globule membranes (MFGM).Discussion: If the results are what we expect, i.e. improved body composition and a less obesogenic, diabetogenic and inflammatory metabolism and gut microbiota composition, a more sustainable nutrient intake for future health and an increased acceptance of healthy foods, they will have a profound impact on the dietary recommendations to infants in Sweden and elsewhere, their eating habits later in life and subsequently their long-term health.Trial registration: NCT02634749. Registration date 18 December 2015.

- OBJECTIVES: To evaluate if dietary vitamin D intake is adequate for sufficient vitamin D status during early winter in children living in Sweden, irrespective of latitude or skin color.METHODS: As part of a prospective, comparative, two-center intervention study in northern (63°N) and southern (55°N) Sweden, dietary intake, serum 25-hydroxyvitamin D (S-25(OH) D), associated laboratory variables, and socio-demographic data were studied in 5 to 7-year-old children with fair and dark skin in November and December.RESULTS: 206 children with fair/dark skin were included, 44/41 and 64/57 children in northern and southern Sweden, respectively. Dietary vitamin D intake was higher in northern than southern Sweden (p=0.001), irrespective of skin color, partly due to higher consumption of fortified foods, but only met 50-70% of national recommendations (10 μg/day). S-25(OH) D was higher in northern than southern Sweden, in children with fair (67 vs. 59 nmol/L; p < 0.05) and dark skin (56 vs. 42 nmol/L; p < 0.001). S-25(OH) D was lower in dark than fair skinned children at both sites (p < 0.01), and below 50 nmol/L in 40 and 75% of dark-skinned children in northern and southern Sweden, respectively.CONCLUSIONS: Insufficient vitamin D status was common during early winter in children living in Sweden, particularly in those with dark skin. Although, higher dietary vitamin D intake in northern than southern Sweden attenuated the effects of latitude, a northern country of living combined with darker skin and vitamin D intake below recommendations are important risk factors for vitamin D insufficiency.

- In regions where sunlight exposure is limited, dietary vitamin D intake becomes important for maintaining status. However, Swedish children have been shown to have deficient or marginal status during the winter months even if the recommended dietary intake is met. Since low vitamin D status has been associated with several disease states, this study investigated the metabolic changes associated with improved vitamin D status due to supplementation.During the 3 winter months, 5-7-year-old children (n=170) in northern (limed, 63 degrees N) and southern (Malmo, 55 degrees N) Sweden were supplemented daily with 2 (placebo), 10 or 25 mu g of vitamin D. BMI-for-age z-scores (BAZ), S-25(OH)D concentrations, insulin concentrations and the serum metabolome were assessed at baseline and follow-up.S-25(OH)D concentrations increased significantly in both supplementation groups (P<.001). Only arginine and isopropanol concentrations exhibited significant associations with improvements in S-25(OH)D. Furthermore, the extent to which S-25(OH)D increased was correlated with a combination of baseline BAZ and the change in serum fructose concentrations from baseline to follow up (P=.012). In particular, the change in S-25(OH)D concentrations was negatively correlated (P=.030) with the change in fructose concentrations for subjects with BAZ >= 0 and consuming at least 20 mu g vitamin D daily. These results suggest that although the metabolic changes associated with improved vitamin D status are small, the effectiveness of dietary supplementation may be influenced by serum fructose concentrations.

- Vitamin D and calcium are essential nutrients with a range of biological effects of public health relevance. This study aimed to validate a short food frequency questionnaire (SFFQ) against a three-day food record (3D record), assessing the intake of vitamin D and calcium in Swedish children during wintertime. In a double-blinded, randomized food-based intervention study on the effect of feeding different daily doses of vitamin D supplement to 5-7-year-old children (n = 85), 79 (93%) participants completed SFFQ1 at baseline and SFFQ2 after the intervention, and 72 were informed to fill in a 3D record. The 28 (39%) children who completed the 3D record were included in this validation study. The baseline level of serum-25 hydroxy vitamin D [S-25(OH)D] was used as a biomarker. The correlation between all three instruments were moderate to strong. SFFQ2 and the 3D record correlated moderately to S-25(OH)D. Bland-Altman analysis showed that SFFQ2 overestimated vitamin D intake by on average 0.6 mu g/day, (limits of agreement (LOA) 5.7 and -4.6 mu g/day), whereas the intake of calcium was underestimated by on average 29 mg/day, (LOA 808 and -865 mg/day). Finally, the validity coefficient calculated for vitamin D using the method of triad was high (0.75). In conclusion, this SFFQ, assessed by a dietician, is a valid tool to assess dietary vitamin D and calcium intake in groups of young children.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aim of the study was to evaluate vitamin D status and effects of vitamin D intervention on bone mineral density (BMD) and content (BMC) in children with fair and dark skin in Sweden during winter.Methods: In a 2-center prospective double-blinded randomized intervention study 5- to 7-year-old children (n = 206) with fair and dark skin in Sweden (55 degrees N-63 degrees N) received daily vitamin D supplements of 25 mu g, 10 mu g, or placebo (2 mu g) during 3 winter months. We measured BMD and BMC for total body (TB), total body less head (TBLH), femoral neck (FN), and spine at baseline and 4 months later. Intake of vitamin D and calcium, serum 25-hydroxy vitamin D (S-25 [OH]D), and related parameters were analyzed.Results: Despite lower S-25(OH)D in dark than fair-skinned children, BMD of TB (P = 0.012) and TBLH (P = 0.002) and BMC of TBLH (P = 0.04) were higher at baseline and follow-up in those with dark skin. Delta (Delta) BMD and BMC of TB and TBLH did not differ between intervention and placebo groups, but FN-BMC increased more among dark-skinned children in the 25 mu g (P = 0.038) and 10 mu g (P = 0.027) groups compared to placebo. We found no associations between Delta S-25(OH)D, P-parathyroid hormone, P-alkaline phosphatase, and Delta BMD and BMC, respectively.Conclusions: BMD and BMC remained higher in dark- than fair-skinned children despite lower vitamin D status. Even though no difference in general was found in BMD or BMC after vitamin D intervention, the increase in FN-BMC in dark-skinned children may suggest an influence on bone in those with initially insufficient vitamin D status.

- Background: Dark skin and low exposure to sunlight increase the risk of vitamin D insufficiency in children. Objective: The aim of the study was to evaluate the amount of vitamin D needed to ascertain that most children >4 y of age attain sufficient serum25-hydroxyvitamin D [S-25(OH) D; i.e., >= 50 nmol/L] during winter regardless of latitude and skin color. Design: In a longitudinal, double-blind, randomized, food-based intervention study, 5- to 7-y-old children from northern (638 degrees N) and southern (558 degrees N) Sweden with fair (n = 108) and dark (n = 98) skin were included. Children, stratified by skin color by using Fitzpa-trick's definition, were randomly assigned to receive milk-based vitamin D-3 supplements that provided 2 (placebo), 10, or 25 mu g/d during 3 winter months. Results: Mean daily vitamin D intake increased from 6 to 17 mu g and 26 mu g in the intervention groups supplemented with 10 and 25 mu g, respectively. In the intention-to-treat analysis, 90.2% (95% CI: 81.1%, 99.3%) of fair-skinned children randomly assigned to supplementation of 10 mu g/d attained sufficient concentrations, whereas 25 mu g/d was needed in dark-skinned children to reach sufficiency in 95.1% (95% CI: 88.5%, 100%). In children adherent to the study product, 97% (95% CI: 91.3%, 100%) and 87.9% (95% CI: 76.8%, 99%) of fair-and dark-skinned children, respectively, achieved sufficient concentrations if supplemented with 10 mu g/d. By using 95% prediction intervals for 30 and 50 nmol S-25(OH) D/L, intakes of 6 and 20 mu g/d are required in fair-skinned children, whereas 14 and 28 mu g/d are required in children with dark skin. Conclusion: Children with fair and dark skin require vitamin D intakes of 20 and 28 mu g/d, respectively, to maintain S-25(OH) D >= 50 nmol/L, whereas intakes of 6 and 14 mu g/d, respectively, are required to maintain concentrations >= 30 nmol/L during winter.
