Abstract
The childhood obesity epidemic has become a growing health concern and one of the potential causes of this is the increase in the frequency of snacking among children. The objective of this study was to explore the short-term effects of dairy and non-dairy snacks on subjective satiety and energy intake in children. Methods: In a repeated-measures design, twenty-three normal weight (5th-85th BMI percentile) children (n=16 girls and 7 boys; aged 9-14 years old) were randomly assigned to one of five isocaloric (180kcal) treatments: deep fried chips (32g), strawberry Greek yogurt (200g), mini sandwich type cookies (39g), mozzarella cheese (63g) and 2% M.F. milk (346g). Following a 12hr fast, participants consumed a standardized breakfast two hours prior to each study session. Visual Analogue Scale questionnaires rating motivation to eat and flavour and texture preferences of the treatments were completed at: 0min (baseline), 15, 30, 45, 90 and 120 min. Ad libitum food intake was measured at a pizza lunch provided at 120min. Results: Food intake was 82kcal less following the mozzarella cheese treatment compared to 2% M.F. milk. (P<0.05) There was an effect of time (P<0.0001), but no treatment or time-by-treatment effect on subjective average appetite. Conclusion: A solid dairy snack (Mozzarella cheese) is effective in reducing food intake in children. Yogurt and milk suppresses food intake similarly to other popular non-dairy snacks, however, they provide better nutrient profiles. Funding source: Dairy Farmers of Canada.
