Kids and young adults who drink no water during the day consume twice the amount of calories from sugary drinks than those who do, according to a new study.
The findings underscore the importance of children having free access to clean water, researchers say.
“Kids should consume water every single day, and the first beverage option for kids should be water,” says Asher Rosinger, assistant professor of biobehavioral health and director of the Water, Health, and Nutrition Lab at Penn State. “Because if they’re not drinking water, they’re probably going to replace it with other beverages, like sugar-sweetened beverages, that are less healthy and have more calories.”
Sugar-sweetened beverages include soda, sweetened fruit juices, sports drinks, energy drinks, and sweetened tea and coffee drinks. They don’t include 100-percent-fruit juices, drinks sweetened with zero-calorie sweeteners, or drinks that people sweeten themselves, like home-brewed coffee or tea.
While other research has shown an overall decline in the consumption of sugar-sweetened beverages, there are still subpopulations of kids in the US who are more likely to consume sugary drinks, Rosinger says.
He and colleagues wanted to better understand how many kids drink water on a given day, how many don’t, and how their caloric intake from sugar-sweetened beverages differ.
It adds up
For the study, which appears in the Journal of the American Medical Association Pediatrics, researchers used data from the National Health and Nutrition Examination Survey, a nationally representative data set that includes information on 8,400 children between the ages of 2 and 19.
“…in parts of the US, some people may not trust their water due to lead or other contamination.”
The data include information about the children’s water and sugar-sweetened beverage consumption, as well as calories from sugary drinks and the percent of total calories coming from sugary drinks.
An analysis of the data showed that on a given day, about 20 percent of children reported drinking no water. Additionally, those children consumed almost twice as many calories from sugar-sweetened beverages—about 200 calories total—than children who did drink water.
While an extra 200 calories may not seem like a lot, it can add up quickly if someone is drinking sugar-sweetened beverages on a regular basis, Rosinger says.
“What you have to remember is that an extra 3,500 calories equals one pound of weight gain. So if you’re not compensating for those extra calories, then over a month, you can potentially gain a pound. Over several months, that could add up.”
Additionally, the researchers found that while the US Department of Agriculture recommends that no more than 10 percent of a person’s daily calories should come from added sugars, children who did not drink any water on a given day tended to exceed this limit from sugary drinks.
Not safe to drink?
While urging people to drink water is important, there are many reasons why kids may not drink any or enough water during the day, Rosinger says.
“It’s important to note that in parts of the US, some people may not trust their water due to lead or other contamination. Water insecurity is a growing problem in the US, so we need to keep that in mind as important context, especially when it comes to parents who may be giving their kids soda or juice because they distrust the water.”
In the future, Rosinger wants to explore possible interventions to help boost water intake in children.
