The flavor of the maternal diet is transferred to women's amniotic fluid and breast milk, so that the amniotic fluid and breast milk become natural transmitters of flavor-related information developing babies are exposed to at early stages of development. We aimed to review the available evidence regarding the impact of early exposure to flavor on child vegetable intake, and to discuss for the first time possible effects of availability or unavailability of particular vegetables because of geographic reasons on these exposures, a variable that has been forgotten in the literature. We have focused on studies that have examined the association of prenatal and early postnatal -at breastfeeding- exposures to vegetable-related flavors with vegetable consumption in children. We have identified that this particular kind of exposures may lead to increases in children's acceptance, liking of and preference for the vegetables. Especially novel has been to identify that these effects might be modulated not only by the particular flavor of the vegetable -bitter vs. sweet- and the time of exposure -prenatal vs. breastfeeding- but also by vegetable availability because of geographic reasons of the place of residence of the mother, a variable that should be taken into account in future research. This would give rise to a new research line aimed at solving the mentioned gap. Finally, a theoretical model of cyclical processes that might explain the origin and perpetuation of transmission of particular patterns of vegetable consumption and vegetables-composed dishes over time in a given population is also included here as another new contribution.

对早期接触可用蔬菜风味的一种新看法是蔬菜消费习惯和蔬菜菜肴食谱的基本机制。

产妇饮食的风味会转移到妇女的羊水和母乳中，因此，羊水和母乳成为与风味相关的信息的自然传播者，正在发育的婴儿会在发育的早期阶段暴露。我们旨在审查有关早期接触风味对儿童蔬菜摄入量的影响的现有证据，并首次讨论由于地理原因，特定蔬菜的可获得性或不可用性对这些接触的可能影响，这一变量已被遗忘在文学中。我们的研究重点是研究母乳喂养时与蔬菜相关的调味品与儿童食用蔬菜之间的关联，这些研究涉及产前和产后早期。我们已经发现，这种特殊的接触方式可能导致儿童对蔬菜的接受程度，喜好程度和偏爱程度增加。尤其新颖的是，这些影响不仅受蔬菜的特殊风味（苦味对甜味）和接触时间（产前对母乳喂养）的影响，而且由于该地区的地理原因而受蔬菜供应的影响母亲的居住状况，这个变量在以后的研究中应予以考虑。这将产生一条旨在解决上述差距的新研究路线。最后，
