No long-term effect of a 2-days intervention on how to prepare homemade food, on toddlers’ skepticism for new food and intake of fruits and vegetables and sweet beverages: a randomized, controlled trial

OBJECTIVE: Optimal nutrition from early age reduces the risk of developing non-communicable diseases later in life. The aim of this study was to examine the long-term effect on toddlers’ fruit and vegetable intake and sweet beverages, and skepticism for new food, of a 2-days’ intervention on how to prepare homemade food for toddlers. RESULTS: The effect of the cooking intervention was evaluated by a randomized, controlled trial where 110 parents of 4–6 months old infants were included. Child diet and food skepticism were measured at 6, 15 and 24 months of age. There were no differences between the control and intervention group in the consumption of fruits and vegetables and intake of water or sweet beverages at 15 and 24 months. There were no differences between the control and intervention group, respectively, in percentage reporting having children who were skeptical regarding new food at baseline (29% vs 20%, p = .372), nor at 3 and 9 months after the intervention (20 vs 18%, p = .804 and 43% vs 32%, p = .383). The intervention did not influence intake of fruits and vegetables, nor did it reduce food skepticism among toddlers. Trial registration first food for infants ISRCTN45864056, 20.05.2016.
