note = {Emerging research indicates that besides innate taste preferences early sensory experiences in infancy via amniotic fluid, breast milk, and infant formula play a crucial role in the development of individual food preferences and dietary behaviour. With the introduction of complementary food (CF) during weaning, the spectrum of different flavours and textures increases further. However, the potential of CF’s sensory properties – particularly with regards to its preparation type, i.e. homemade or commercial – in shaping later food preferences has not been extensively examined so far. Thus, the overall aim of this thesis was to determine existing trends in complementary feeding practice, and their relevance for later dietary behaviour. Three analyses (Studies I-III) were conducted using data from the German DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) Study, an ongoing, open cohort study.
Study I (n=366) revealed that commercial CF dominated infant feeding, especially in infants who were breast-fed for a shorter duration and whose mothers had a lower educational status. Both commercial and homemade CF showed opposing, nonlinear age trends; however, no time trends could be found during the observed study period (2004-2012). In Study II (n=281), a higher commercial CF proportion was associated with lower vegetable intake in infancy in both sexes. Prospectively, only boys showed an inverse association between a higher commercial CF proportion and a lower vegetable intake in preschool age as well as lower total fruit and vegetable intake in preschool and primary school age. For girls, no significant prospective association could be observed. With respect to fruit and vegetable variety, no distinct associations were found. Study III (n=288) indicated that infants with a high contribution of commercial CF had higher odds for a high consumption of added sugar from CF as well as a high total added sugar intake. Commercial CF consumption in infancy was also positively related to added sugar intake in preschool and primary school age.
In conclusion, this thesis highlights the constantly high and widespread consumption of commercial CF in today’s infant nutrition and further provides first evidence of the preparation type of CF being a relevant modifiable factor shaping long-term dietary behaviour. Although the question, whether it is the early diet tracking through childhood or the sensory properties of CF imprinting later taste and food preferences cannot be conclusively answered, these results underline that the occasional provision of homemade CF can help infants to develop beneficial food preferences and contribute to a favourable dietary behaviour by means of increasing fruit and vegetable consumption as well as limiting added sugar intake in childhood.},
