“…Children's food acceptance and dietary intake are influenced by sensory properties of food, such as odor [54], color [55], and texture [56,57,58]. Children who are picky eaters may be more sensitive to olfactory cues [54] and tactile stimuli [59], which could influence their intake and liking of foods. Future studies are needed to understand how children's food preferences and eating behaviors are shaped by the appearance, texture, and smell of food.…”

Variants in Chemosensory Genes Are Associated with Picky Eating Behavior in Preschool-Age Children

Background/Aims: Picky eating is prevalent among preschoolers and is associated with risk of both underweight and overweight. Although differences in taste perception may be due to genetic variation, it is unclear whether these variations are related to picky eating behavior. The aim of this study was to investigate the association of 6 single nucleotide polymorphisms (SNPs) in 5 candidate genes related to chemosensory perception with picky eating behavior and adiposity in a cohort of preschool-aged children. Methods: Parents of 2- to 5-year-old non-Hispanic white preschoolers (n = 153) responded to survey questions on demographics, and information regarding their child's breastfeeding history and picky eating behavior. Height and weight were measured to calculate body mass index (BMI) z-scores using standard growth charts, and saliva was collected for genotyping. Generalized linear models were used to examine associations between picky eating behavior and BMI z-scores with genetic variation. Results: When controlling for child age, sex, breastfed status, and parent education level, SNPs in TAS2R38 (rs713598) and CA6 (rs2274327) were associated with picky eating behavior in children. There was no association between SNPs and BMI z-scores. Conclusion: Genes related to chemosensory perception may play a role in children's picky eating behavior.

“…Both parental educational levels and breastfeeding predict the higher consumption of vegetables [ 44 ]. Higher SES mothers were more likely to have foods such as fruit and vegetables in the house, certainly if they are eating these themselves [ 45 ] the infant will therefore be exposed to the sight and smell of the foods, as well as the taste via breast milk, and these in turn will affect food intake [ 46 , 47 •]. It could also be that higher SES mothers who breastfeed are more likely to give the infant home-prepared foods rather than to rely on commercial baby food, and this trend in itself has been shown to predict subsequent fruit and vegetable intake in older children [ 14 , 48 , 49 ].…”

“…It has been found that preschool children who are tactile defensive have more problems with food of various textures [ 64 ]; that boys with higher smell reactivity are more neophobic [ 47 •] and that preschool children with taste, smell and tactile sensitivity are more neophobic and less likely to model their mother’s fruit and vegetable consumption [ 65 ]. The effects of this sensory sensitivity can also be observed in the food choices of older children; taste/ smell sensitivity was found to be associated with a limited range diet in children from 5 to 10 years [ 66 ].…”

Early Eating Behaviours and Food Acceptance Revisited: Breastfeeding and Introduction of Complementary Foods as Predictive of Food Acceptance

Current dietary advice for children is that they should eat at least five portions of fruit and vegetables a day (Department of Health. National Diet and Nutrition Survey, 2014). However, many parents report that children are reluctant to eat vegetables and often fail to comply with the five-a-day rule. In fact, in surveys carried out in areas in the UK, the number of children eating according to the five-a-day rule has been found to be as low as 16 % (Cockroft et al. Public Health Nutr 8(7):861–69, 2005). This narrative review looks at those factors which contribute to food acceptance, especially fruit and vegetables, and how acceptance might be enhanced to contribute to a wider dietary range in infancy and later childhood. The questions we address are whether the range of foods accepted is determined by the following: innate predispositions interacting with early experience with taste and textures, sensitive periods in infancy for introduction, breastfeeding and the pattern of introduction of complementary foods. Our conclusions are that all of these factors affect dietary range, and that both breastfeeding and the timely introduction of complementary foods predict subsequent food acceptance.

“…Moreover, infants with a different taste or olfactory sensitivity may also react differently to vegetables: some infants are more prone to accept foods (in particular vegetables) with a sweet, sour or savory taste [31] ; some infants who are highly reactive to food odors may show higher dislike for these foods [47,48] . The high reactivity toward odors, not tastes, was shown to be associated with a higher food neophobia at 24 months of age [49] , underlying the interrelationship between the infant's sensitivity to flavor compounds in foods and his/her eating behavior, in particular at an age when autonomy develops and children have acquired enough mobility to make their own food choices. It was indeed observed that between the ages of 2 and 3 years, when children are offered to the possibility of making their own food choices for lunch, the variety of their choices decreases, even if the offered foods are familiar [50] , suggesting that by this age, children have learned to recognize foods and make choice decisions according to their preferences.…”

Infants are born equipped to ingest nutrients, but because of the transitions in the mode of feeding in the first years (from “tube” feeding in utero to eating table foods with the family), they have to learn how, what and how much to eat. Eating behavior established during early years may follow throughout childhood; therefore, it is fundamental to understand the most important drivers of the early development of eating behavior. Beyond the first flavor discoveries during the gestational and lactation periods (through the infant's exposure to flavors from foods of the mother's diet), the most important phases for learning food preferences and appetite control may be the beginning of complementary feeding (CF). Infants discover the sensory (texture, taste and flavor) and nutritional properties (energy density) of foods that will ultimately compose their adult diet. This brief review shows that several feeding practices influence the development of eating behavior: breastfeeding; repeating the presentation of a food, even if it seems initially disliked; introducing a variety of different foods rapidly in the CF process; offering foods in an appropriate way to make their sensory characteristics appealing to infants. More research is needed to understand in a combined way the effectiveness and long-term effect of these practices to promote healthy eating behaviors.
