- 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.

- We investigated a family from northern Sweden in which three of four siblings have congenital chylomicronemia. Lipoprotein lipase (LPL) activity and mass in pre- and post-heparin plasma were low, and LPL release into plasma after heparin injection was delayed. LPL activity and mass in adipose tissue biopsies appeared normal. [35S]Methionine incorporation studies on adipose tissue showed that newly synthesized LPL was normal in size and normally glycosylated. Breast milk from the affected female subjects contained normal to elevated LPL mass and activity levels. The milk had a lower than normal milk lipid content, and the fatty acid composition was compatible with the milk lipids being derived from de novo lipogenesis, rather than from the plasma lipoproteins. Given the delayed release of LPL into the plasma after heparin, we suspected that the chylomicronemia might be caused by mutations in GPIHBP1. Indeed, all three affected siblings were compound heterozygotes for missense mutations involving highly conserved cysteines in the Ly6 domain of GPIHBP1 (C65S and C68G). The mutant GPIHBP1 proteins reached the surface of transfected CHO cells but were defective in their ability to bind LPL (as judged by both cell-based and cell-free LPL binding assays). Thus, the conserved cysteines in the Ly6 domain are crucial for GPIHBP1 function.

- Background: Compositional changes in the early‐life gut microbiota have been implicated in IgE‐associated allergic diseases, but there is lack of longitudinal studies. We examined gut microbiota development from infancy to school age in relation to onset of IgE‐associated allergic diseases. At 8 years of age, we also examined the relationship between gut microbiota and T‐cell regulation, estimated as responses to polyclonal T‐cell activation.Methods: Stool samples were collected from 93 children at 4, 6, 13 months, and 8 years of age. The gut microbiota was profiled using 16S rRNA gene sequencing. Peripheral blood was drawn from all children, and mononuclear cells were polyclonally activated. Levels of IL‐10 and FOXP3 mRNA copies were determined using real‐time quantitative reverse transcriptase‐PCR.Results: At 8 years of age, 21 children were diagnosed with IgE‐associated allergic disease and 90% displayed allergic comorbidity. Seventy‐two children were nonallergic and nonsensitized. Statistical tests with multiple testing corrections demonstrated temporal underrepresentation of Ruminococcus and consistent underrepresentation of Bacteroides, Prevotella, and Coprococcus in allergic compared to nonallergic children from infancy to school age. The gut microbiota of the allergic 8‐year‐olds was enriched in Bifidobacteriumand depleted of Lactobacillus, Enterococcus, and Lachnospira. In allergic 8‐year-olds, Faecalibacterium correlated with IL‐10 mRNA levels (rs = 0.49, Padj = 0.02) with the same trend for FOXP3 (rs = 0.39, Padj = 0.08).Conclusions: We identified both temporal and long‐term variation in the differential abundance of specific bacterial genera in children developing IgE‐associated allergic disease. Improved dietary interventions aiming at expanding immune‐modulatory taxa could be studied for prevention of allergic disease.

- GOALS OF WORK: The purpose of this study was to better understand various variables related to food intake and eating problems in children with cancer during their chemotherapy. PATIENTS AND METHODS: Twenty-two consecutively admitted children, diagnosed with cancer and undergoing chemotherapy, participated in this study. Twenty-one of them, their parents and attending nurses participated in semi-structured interviews. Ten of the children underwent a taste acuity test, and recognition thresholds for the four basic tastes were determined. MAIN RESULTS: The shared view of both children and parents was that altered taste was the predominant cause of the eating problems. In contrast, the nurses perceived that nausea was the most important cause of the children's eating problems. In addition, psychological aspects such as learned food aversions and negative attitudes towards hospital food were regarded as important by children, parents and nurses. The taste test showed that the patients had higher thresholds for bitter taste and made more taste recognition errors compared to controls. CONCLUSIONS: Changes seem to exist both in the primary gustatory sense as well as in food perception in paediatric cancer patients undergoing chemotherapy. Single solutions, such as efforts to serve "tasty food", do not suffice alone. A more effective solution may be to combine different strategies and combinations of oral, enteral and parenteral nutrition should be considered to prevent malnutrition.

- The inorganic anions nitrate and nitrite are oxidation products from endogenous nitric oxide (NO) generation and constituents in our diet. A nitrate-nitrite-NO pathway exists in which nitrate can be serially reduced to bioactive NO. The first step of this pathway occurs in the oral cavity where oral bacteria convert salivary nitrate to nitrite, whereafter nitrite is reduced to NO systemically by several enzymatic and non-enzymatic pathways. Data are scarce regarding salivary levels and oral conversion capacity of these anions in infants. We measured salivary nitrate and nitrate in infants at 4 and 12 months of age and related values to age, sex, dietary pattern and oral microbiome. Saliva was collected from a total of 188 infants at 4 and 12 months of age. Salivary nitrate, nitrite and nitrite/nitrate ratio as a measure of oral nitrate-reducing capacity were analyzed by HPLC and related to age, sex, type of diet (breast milk or formula) and oral microbiome. There was no difference in salivary nitrate, nitrite or nitrite/nitrate ratio between boys and girls at any age. At 4 months levels of these parameters were lower than what has been described in adults but they had all increased significantly at 12 months of age. At 4 months of age salivary nitrite/nitrate ratio was lower in breast-fed compared to formula-fed infants, but these differences disappeared at 12 months. Several bacterial species were associated with oral nitrate reducing capacity including Prevotella, Veillonella, Alloprevotella and Leptotrichia. We conclude that in infants there is an increase in salivary nitrate and nitrite as well as in oral nitrate-reductase capacity during the first year of life. Differences observed at 4 months of age between breast-fed and formula-fed infants disappear at one year of age.

- Microbial exposure is necessary for the development of normal immune function, which has driven the idea of using probiotics for treatment and prevention of immune-mediated diseases in infancy and childhood. Mounting evidence indicates that probiotics have immunomodulatory effects. However, the mechanisms are still poorly understood. Specific antibody response is a valuable proxy for immune system maturation status in infancy. We aimed at determining the impact of Lactobacillus F19 (LF19) during weaning on infections and IgG antibody responses to routine vaccines. In a double-blind, placebo-controlled randomized intervention trial, infants were fed cereals with (n = 89) or without LF19 (n = 90) from 4 to 13 months of age. Infants were immunized with DTaP (diphtheria and tetanus toxoid and acellular pertussis), polio and Hib-conjugate vaccines at (3), 5(1/2) and 12 months of age. We assessed the number of days with infections, antibiotic prescriptions and antibody concentrations to Hib capsular polysaccharide (HibPS), diphtheria toxin (D) and tetanus toxoid (T) before and after the second and third doses. Days with infectious symptoms did not differ between the groups. Days with antibiotic prescriptions were fewer in the LF19 group (p = 0.044). LF19 enhanced anti-D concentrations when adjusting for breastfeeding duration and colonization with LF19 (p = 0.024). There was an interaction of the intervention and colonization with LF19 on anti-T concentrations during the course of vaccination (p = 0.035). The anti-HibPS concentrations were higher after the first and second dose of Hib vaccine in infants breastfed <6 months compared with those breastfed > or =6 months (p < 0.05), with no effect by LF19. In conclusion, feeding LF19 did not prevent infections, but increased the capacity to raise immune responses to protein antigens, with more pronounced effects in infants breastfed <6 months.

- Aim: To investigate effects of iron-fortified foods (FFs) and medicinal iron drops (MD) on iron status in infants. Methods: Data from one MD and one FF study were compared. Infants were divided into groups depending on the predominant source and amount of dietary iron during 6–9 months of age: MD: Medicinal iron drops (1 mg/kg/day). FF: iron intake >1.3 mg/kg/day, predominantly from FF and no iron supplements. Low iron (LI) group: iron intake <1.3 mg/kg/day and no iron supplements. Results: Mean iron intake did not differ between MD (n = 30) and FF (n = 35) groups but was lower in the LI (n = 232) group. The FF group had significantly higher mean Hb at 9 months compared to the MD and LI groups (120 vs. 115 g/L and 120 vs. 116 g/L, respectively, p ≤ 0.005). The MD group had significantly higher mean SF at 9 months compared to the FF and the LI groups (46 vs. 23 μg/L and 46 vs. 26 μg/L, respectively, p < 0.001). Conclusions: Our results suggest that, in healthy, term, nonanaemic 6–9-month-old infants, iron given as medicinal iron drops is primarily deposited into iron stores while iron given as iron-fortified foods is primarily utilized for Hb synthesis.

- BACKGROUND: Supplementation of formula with bovine milk fat globule membranes has been shown to narrow the gap in immunological and cognitive development between breast-fed and formula-fed infants.METHOD: In a double-blinded randomized controlled trial 160 formula-fed infants received an experimental formula (EF), supplemented with bovine milk fat globule membranes, or standard formula until 6 months of age. A breast-fed reference group was recruited. Lipidomic analyses were performed on plasma and erythrocyte membranes at 6 months and on serum at 4 and 12 months of age.RESULTS: At 6 months of age, we observed a significant separation in the plasma lipidome between the two formula groups, mostly due to differences in concentrations of sphingomyelins (SM), phosphatidylcholines (PC), and ceramides, and in the erythrocyte membrane lipidome, mostly due to SMs, PEs and PCs. Already at 4 months, a separation in the serum lipidome was evident where SMs and PCs contributed. The separation was not detected at 12 months.CONCLUSIONS: The effect of MFGM supplementation on the lipidome is likely part of the mechanisms behind the positive cognitive and immunological effects of feeding the EF previously reported in the same study population.
