Were do they get their protein from? : Dietary nutrient intake of children in Helsinki day-care centres eating either vegan or omnivore meals

Background: A few Finnish municipalities have chosen to offer the option of a vegan diet at day-care if the parents request it. The food offered at day-care plays an important part in a child’s nutrition and should be guided by official recommendations. As little evidence exists for the adequacy of a vegan diet for children in day-care more studies on the subject is needed. The food provided by the day-care should cover 2/3 of the daily energy requirements and the quantity of saturated fat, salt and sucrose should be limited. Aim: The aim of this thesis is to compare and analyse the nutritional adequacy of vegan and omnivore meals offered by the municipality of Helsinki. Additionally, to describe the dietary sources of intakes from both meals. Data and methods: This thesis is part of the MIRA Helsinki study, conducted by the University of Helsinki. The objective of the project is to study the impact of a vegan diet on the nutritional status of children in daycare in Helsinki. The data for this thesis was collected through food diaries. The children range in age from one to six years and are divided into two groups based on meals eaten at day-care, vegan meals (n=9) and omnivore meals (n=16). All statistical analyses were done with the SPSS program (version 25). Results: In most cases the dietary intake followed official recommendations. Of concern is that salt intake was high in both groups. The two diets provided similar amounts of energy, carbohydrates and sucrose at day-care. However, protein (p<0,001), fat (p=0,008) and fibre (p<0,001) intakes were significantly more favourable when eating vegan meals. The group eating vegan meals also had a higher intake of monounsaturated and polyunsaturated fat (p=0,007; p<0,001) as well as linolenic acid (p<0,001) and αlinolenic acid (p<0,001) in comparison to the omnivore group. Further, the omnivore group had higher intakes of cholesterol (p<0,001) and saturated fat (p=0,007). There was no dietary intake of EPA and DHA in the vegan meals. Intakes of saturated fat and cholesterol outside the day-care were higher than at day-care. The vegan meal group had significantly higher intakes of folate (p<0,001), iron (p<0,001) and zinc (p=0,001) while lower intakes of iodine (p=0,006) and calcium (p=0,01), were noted in comparison to the omnivore group. Although the intake of vitamin C does not significantly differ between the groups, the intake at day-care is low in both groups (vegan meals 38 %, and omnivore 21 % of total intake). In the diet of the children eating vegan meals at day-care, fortified plant-based milk played a central role as a source of many nutrients. Conclusions: Because of the small sample size no general conclusions can be drawn from these results, but it seems the vegan meals have many positive characteristics compared to the omnivore meals. The results may give an insight to nutritional differences between a vegan and an omnivore diet of under school age children in Helsinki. A more plant-based diet would be a sustainable choice for the future, but supplementation is recommended to guarantee sufficient intakes of critical nutrients. More studies are needed on the long-term effects of a vegan diet on young children and the characteristics of a vegan diet in Finland.
