Sugar-sweetened drinks: Short on nutrition, long on risk
Sugar-sweetened beverages (labeled as fruit drinks) often replace whole fruits in childhood diets.8 As a result, children may fail to meet recommendations for intake of whole fruits and vegetables, which contain fiber and nutrients essential to growth.
Consumption of fruit drinks and other sugar-sweetened beverages by American children has increased 135% since 1977; such drinks account for roughly 9% of daily energy intake.9 Data from the Feeding Infants and Toddlers Survey (FITS) indicate that 100% fruit juice and sugar-sweetened beverages are now the second and third leading sources, respectively, of energy (and carbohydrates) for American children between 1 and 2 years of age.3
Data from the National Health and Nutrition Examination Survey (NHANES) suggest that overweight children and adolescents consume more sugar-sweetened beverages than those who are not overweight.10 Other cohort data show that children who regularly consume sugar-sweetened beverages are twice as likely to be overweight by 5 years of age as children who don’t.11 However, 1 cohort of 521 children followed longitudinally from 5 to 9 years showed no association between sugar-sweetened beverage intake and body fat.12
A recent systematic review of 30 studies (15 cross-sectional, 10 prospective cohort, and 5 experimental trials) supports a link between consumption of sugar-sweetened beverages and childhood obesity.13
What about tooth decay?
Excess intake of both sugar-sweetened beverages14 and fruit juice15 has been associated with increased risk of dental caries. Excess intake is defined as more than 6 oz per day in children 1 to 6 years of age and more than 12 oz per day in children 7 to 18 years. To help reduce the risk for dental caries, children should drink juice from a cup.
Recommendations
The American Academy of Family Physicians,16 American Academy of Pediatrics,6 American Heart Association,17 and World Health Organization18 all recommend breast milk as the preferred source of infant nutrition for the first 6 (preferably 12) months of life. The US Preventive Services Task Force recently emphasized the need for primary care physicians to further promote breastfeeding efforts.19
Infants shouldn’t be given fruit juice before 6 months of age.17 If juice is offered, it should be 100% fruit juice in a cup, not a bottle. Children 1 to 6 years of age should drink no more than 4 to 6 oz of 100% fruit juice per day. Children 7 to 18 years of age should limit intake to 12 oz of 100% fruit juice per day.17 Infants, children, and adolescents shouldn’t drink unpasteurized juice.20
The American Heart Association recommends that children 1 to 3 years of age consume the equivalent of 1 cup of whole fruit per day. Children from 4 to 13 years should consume 1.5 cups per day.17
