“…Initial acceptance of a novel liquid was greater in those immature animals that experienced a variety of flavored waters. Comparable findings were not observed in mature animals [2]. In field studies, Provenza and colleagues demonstrated that when the nutritional content of the diet was held constant, lambs preferred to forage in locations that offered a variety of flavors [5].…”

“…Moreover, these infants also experienced different pairs of food and ate varying amounts of these from one day to the next, providing them with sensory diversity. Exposure to such multiple sensory contrasts might have accelerated the "transfer of diversity" effect [2] by providing more varied flavor experience and more opportunities to condition flavor preferences based on the post-ingestive reinforcing effects of these nutritious foods [8,21,22]. Because one member of the pair was experienced the day before, the infants were also provided with continuity in flavor experiences which may have eased the acceptance of the novel food in the pair [8,23].…”

The present manuscript describes two experimental studies that were conducted to explore the effects of an 8-day exposure to a particular food or a variety of foods between and/or within meals on fruit and vegetable acceptance in 74 infants. Whether the dietary experience modified acceptance depended on the flavors of foods experienced, whether the experience occurred between or within meals or both, and whether the target food was a fruit or vegetable. In the first study, we found that 8 days of dietary exposure to pears or a variety of fruits between meals (not including pears) resulted in greater consumption of pears by the infants but this increased acceptance did not generalize to green beans. In the second study, we found that 8 days of vegetable variety both between and within meals led to increased acceptance of green beans, carrots and spinach. Those infants who experienced green beans alone or a variety of vegetables between meals also tended to eat more green beans after the exposure. These findings suggest that not only can infants clearly discriminate flavors but repeated opportunities to taste a particular or a varietyof foods may promote willingness to eat fruits and vegetables, the consumption of which is generally low in the pediatric population and the acceptance of which is difficult to enhance beyond toddlerhood.

“…Animal model studies suggest that the longterm effects of variety are more pronounced when variety is experienced during infancy. 105 In many countries, there exists a common folklore that fruits should not be introduced before vegetables, because children's inherent preference for sweets might interfere with their later acceptance of vegetables. In cultures in which fruits are introduced early, however, such introduction does not seem to interfere with vegetable consumption during infancy.…”

Summary of the Presentations at the Conference on Preventing Childhood Obesity, December 8, 2003

ABSTRACT. Objective. Because of the rising rates of childhood obesity, we set out to determine what is known about its causes and what could be done to prevent additional increases.Methodology. A meeting was convened of experts in areas that bear on prevention of obesity development during intrauterine life, infancy, and very early childhood. They presented recent data and their interpretations of the stage of our current knowledge in related areas. They also proposed possible useful interventions and future directions for research.Findings. The speakers' talks indicated that (1) breastfeeding as currently practiced seems to be significantly (albeit weakly) protective against obesity and should be encouraged as the preferred method of feeding infants for as long a duration as practical during the first year of life; (2) infant-feeding practices are changing in a way that may predispose to obesity (eg, soda and french fries are being fed to infants as young as 7 months of age), possibly altering taste preferences for foods and beverages that are energy dense and nutrient poor; (3) although little is known about parenting styles (eg, authoritative versus permissive), parenting style is likely to be a fruitful area of current research into childhood obesity etiology; and (4) the pattern of weight changes in the first few years of life may contribute to later risk of obesity.Conclusions. Children's obesity will continue to be a growing problem unless we improve understanding of the key factors likely to be operative during intrauterine life, infancy, and very early childhood, identify those in whom intervention would have the greatest effect, design and evaluate preventive interventions, and promote those that are successful.

Amniotic fluid can act as an appetitive unconditioned stimulus in preweanling rats

Studies in humans and animals indicate that exposure to flavors in the amniotic fluid during the later gestational period may induce preferences for those flavors. Considering that during the last prenatal period the amniotic fluid contains substances that activate the opioid system, and that this system plays a critical role in the acquisition of olfactory preferences early in life, it has been hypothesized that the amniotic fluid may acquire appetitive unconditioned properties during this period. This has been tested in an experiment in which preweanling rats were exposed to alcohol odor (CS) paired or unpaired with the intraoral infusion of amniotic fluid (US) collected on gestational day 20. The pairing of these two stimuli induced an enhanced palatability of alcohol's flavor as well an increased intake of the drug. These results support the idea that amniotic fluid acquires appetitive unconditioned properties during the last days of gestation and suggest that associative mechanisms involving the amniotic fluid could be underlying odor and taste preferences acquired through fetal exposure.
