Feeding frozen complementary foods promotes food acceptance in infants: The randomized intervention trial Baby Gourmet.

Infancy may represent a sensitive window for establishing food preferences that could affect the individual's long-term potential to establish healthy eating patterns. Our study was based on the hypothesis that preserving the natural flavor of the ingredients of commercially prepared complementary foods would increase the acceptance of new foods, especially vegetables. Frozen vegetable-based meals for infants were developed to preserve the natural taste of the ingredients better than sterilization of meals in jars. In a 3-month randomized, controlled intervention study, 51 infants were fed either frozen menus (intervention group) or commercial sterilized meals in jars (control group) on at least 5 days per week. Then the acceptability of a known vegetable-based puree was tested in comparison to an unknown puree, measuring the quantities consumed and also the mother's assessment of the infants' liking. In conclusion, the results of this study clearly indicated that infants fed vegetable-based frozen meals for 3 months accepted a new vegetable better than infants fed sterilized commercial meals in jars.
