Abstract [en]

Overreporting of dietary intake in infants is a problem when using food records (FR), distorting possible relationships between diet and health outcomes. Image-assisted dietary assessment may improve the accuracy, but to date, evaluation in the pediatric setting is limited. The aim of the study was to compare macronutrient and energy intake by using an active image-assisted five-day FR against a regular five-day FR, and to validate image-assistance with total energy expenditure (TEE), was measured using doubly labeled water. Participants in this validation study were 22 healthy infants randomly selected from the control group of a larger, randomized intervention trial. The parents reported the infants’ dietary intake, and supplied images of main course meals taken from standardized flat-surfaced plates before and after eating episodes. Energy and nutrient intakes were calculated separately using regular FR and image-assisted FRs. The mean (± standard deviations) energy intake (EI) was 3902 ± 476 kJ/day from the regular FR, and 3905 ± 476 kJ/day from the FR using active image-assistance. The mean EI from main-course meals when image-assistance was used did not differ (1.7 ± 55 kJ, p = 0.89) compared to regular FRs nor did the intake of macronutrients. Compared to TEE, image-assisted FR overestimated EI by 10%. Without validation, commercially available software to aid in the volume estimations, food item identification, and automation of the image processing, image-assisted methods remain a more costly and burdensome alternative to regular FRs in infants. The image-assisted method did, however, identify leftovers better than did regular FR, where such information is usually not readily available. View Full-Text

Abstract [en]

Background: Early nutrition is fundamental to growth and development. Infants develop long lasting food preferences very early in life from food exposures when the brain is impressionable and sensory pathways are receptive. Early food experiences from bitter and sour tastes found in fruits and vegetables can establish longlasting food preferences and healthy eating behavior. Fruits and vegetables can protect against future non-communicable diseases such as cardiovascular diseases, type 2 diabetes, overweight, obesity and cancer. Nordic fruits, berries and vegetables offer high environmental sustainability and favorable taste compositionto establish a variety of food preferences. In this thesis, the focus is on early feeding among healthy, full-term infants and how to establish eating based on Nordic foods.

Methods: The thesis is based on the randomized, controlled trial Optimized complementary feeding study (OTIS), with three papers on the outcomes of the trial and one validation paper. In the trial, the experimental Nordic group (n=125) consumed a diet based on Nordic foods, reduced in protein whereas the control group (n=125) followed the current nutritional recommendations for infants from the Swedish Food Agency. The Nordic group was exposed to a variety of flavors from Nordic, homemade fruit, berry and vegetable purées according to a taste portion schedule with repeated exposures for 24 days during 4-6 months of age. From 6 to 18 months of age the Nordic group experienced a multicomponent intervention of homemade Nordic baby food recipes, family recipes and protein-reduced baby food products together with parental support through social media. The control group followed the Swedish recommendations on how to introduce taste portions and solid foods and were supplied with commercial baby food products with regular content. At baseline, 9, 12 and 18 months of age anthropometry, blood samples, urine samples, questionnaires and dietary data were collected.

Results: Of the 250 infants, 82% (n=206) finished the study until 18 months of age. The attrition rate was higher in the Nordic group (p=0.012). The Nordic group consumed more plant-based foods as fruits, berries, roots and vegetables during the entire study period except at 6 months of age. The protein intake was higher in the control group throughout the study. Plasma urea was higher in the control group as a response to the higher protein intake and plasma folate was higher in the Nordic group as a reflection of the higher fruit and vegetables intake. There were no differences in growth, total energy intake, iron status, breastfeeding durationor any demographic variables between the groups.

Conclusions: A Nordic diet, reduced in protein, increasedthe daily intake of fruit, berries, roots and vegetables, establishing a preferable eating pattern lasting over 12 months. Parental support and systematical flavor learning of Nordic foods may have impacted the infants’ dietary intake in the Nordic group. The Nordic diet is both feasible and safe for infants’ growth, nutritional requirements and development during complementary feeding period between 4-18 months of age. Thus, it may serve as a healthy and environmentally sustainable alternative to future infants and their parents.
