In a recent study of Project Viva participants, a group of investigators led by Kendrin Sonneville examined whether children’s consumption of juice and water at 1 year of age was associated with intake of juice, intake of SSBs (fruit drinks and soda), and BMI in early childhood (~3 years) and mid-childhood (~8 years). The investigators aimed to determine whether juice may act as a “gateway drink”, with higher intake by young children establishing preferences for sweet beverages in later childhood. Their results supported this hypothesis; children who were given juice at 1 year of age drank more juice and SSBs in early and mid-childhood than children who did not drink any juice at 1 year. Juice intake at 1 year was also associated with BMI in both early and mid-childhood, but not with weight-for-length at 1 year. This suggests that even if early juice introduction does not result in immediate gains in adiposity, it may establish a pattern of increasing inclusion of SSBs in the child’s diet. Since SSB intake is associated with increased weight gain in both children and adults, early programming of a preference for sweet beverages can have a lasting impact on weight status.
As my baby approaches the 6-month mark and I plan for his introduction to sources of calories other than breast milk, studies such as this one give me even more to think about. Based on his reaction to the sugar-sweetened vitamin D drops provided by my pediatrician’s office, I suspect that offering juice would be a reliable way to elicit a rewarding smile. However, in deciding when to introduce juice into his diet, I’ll certainly consider this evidence that I may be programming his future taste preferences to favor obesogenic sugary products.
