Insights
Early infant formula type impacts children's taste preferences. Protein hydrolysate formulas led to a preference for sourer juice, while sweet preferences were linked to dietary sugar exposure.
Area of Science:
- Pediatric Nutrition
- Sensory Science
- Child Development
Background:
- Early life experiences significantly shape lifelong dietary habits and flavor preferences.
- Infant feeding practices, including formula type, may influence sensory development.
- Understanding factors affecting taste preferences is crucial for child health and nutrition.
Purpose of the Study:
- To investigate the impact of early infant formula exposure on children's preferences for sweet and sour tastes.
- To determine if specific formula types influence the acceptance of different flavor intensities in juice.
- To explore the relationship between early experiences and current sweet and sour taste preferences in children.
Main Methods:
- Eighty-three children participated, grouped by infant formula type and age.
- A forced-choice, sip-and-swallow procedure was employed to assess taste preferences.
- Preference levels for sweetness and sourness in juice were quantitatively measured.
Main Results:
- Children fed protein hydrolysate formulas (sour/bitter taste) showed a preference for higher citric acid levels in juice compared to controls.
- No significant differences in sweet preference were found based on formula type.
- Sweet preference correlated with the sugar content of preferred cereals and maternal sugar addition habits.
Conclusions:
- Early exposure to specific taste profiles, like those in protein hydrolysate formulas, can shape later flavor preferences.
- Dietary experiences, including sugar intake from cereals and habitual sugar addition, influence sweet taste preferences.
- Childhood flavor preferences are a complex interplay of early sensory experiences and ongoing dietary factors.
Abstract:
We investigated the effects of early experience on sweet and sour preferences in children. Eighty-three children were divided into four groups based on the type of formula fed during infancy and age. By using a forced-choice, sip-and-swallow procedure, we determined the level of sweetness and sourness preferred in juice. Children who were fed protein hydrolysate formulas, which have a distinctive sour and bitter taste and unpleasant odor, preferred higher levels of citric acid in juice when compared to older children who were fed similar formulas. No such difference was observed between the groups for sweet preference. However, the level of sweetness preferred in juice was related to the sugar content of the child's favorite cereal and whether the mother routinely added sugar to their foods. These data illustrate the wide variety of experiential factors that can influence flavor preferences during childhood.
