Root beer is a popular carbonated soft drink in North America, often associated with childhood treats and ice cream floats. Parents frequently wonder about its appropriateness for their children, given its status as a soda. While root beer is generally non-toxic, the answer depends heavily on the specific ingredients, particularly sweeteners and flavorings, and the frequency of consumption. This analysis addresses the main health concerns and provides practical advice for parents navigating this common beverage choice.
The Primary Health Concern: Sugar and Artificial Sweeteners
The most significant health concern with root beer, like most soft drinks, is the high content of added sugars, such as sucrose or high-fructose corn syrup. A single 12-ounce serving of standard root beer can contain 40 to 45 grams of sugar, approximately 10 teaspoons. This quantity often exceeds the recommended daily limit for added sugars in children, contributing substantial empty calories to their diet.
Regular consumption of these sugar-sweetened beverages is linked to an increased risk of childhood obesity and Type 2 diabetes later in life. The sugary liquid also feeds oral bacteria, which produce acid that erodes tooth enamel. This makes root beer a leading contributor to dental cavities and overall tooth decay in children.
Even diet or “sugar-free” root beers, which use non-caloric artificial sweeteners like sucralose or aspartame, present a different set of considerations. While the U.S. Food and Drug Administration (FDA) deems them generally safe within Acceptable Daily Intake (ADI) levels, the American Academy of Pediatrics (AAP) suggests more study is needed on their long-term effects on metabolism and taste preferences. Some research suggests non-nutritive sweeteners may sustain a preference for overly sweet tastes, potentially affecting future food choices. Artificially sweetened drinks are acidic and can still contribute to dental erosion.
Caffeine Content and Unique Flavoring Agents
Most major brands of root beer are naturally caffeine-free, distinguishing them from many other sodas. However, parents must check the ingredient label carefully, as some popular brands, such as Barq’s regular variety, contain added caffeine. This typically amounts to around 22 milligrams per 12-ounce can. Pediatric experts recommend avoiding caffeinated beverages for children under five years old.
The unique flavor historically came from the root bark of the sassafras tree. This traditional ingredient contained a compound called safrole, which the FDA banned in 1960 for use in commercially produced food and drugs. The ban was due to concerns about its potential carcinogenicity based on high-dose studies in lab animals. Modern commercial root beers no longer use sassafras containing safrole, relying instead on artificial flavorings or processed, safrole-free extracts to replicate the characteristic taste.
Practical Guidelines for Consumption
Given the lack of nutritional value in soft drinks, major health organizations recommend that parents avoid giving sugar-sweetened and low-calorie sweetened beverages to young children entirely. Pediatric beverage guidelines specifically recommend against introducing any sweetened beverages for children under five.
For older children, root beer should be reserved as an infrequent treat, not a regular daily beverage. Portion control is important; serving a small amount in a cup, rather than an entire can or bottle, limits both sugar intake and the duration of acid exposure to teeth. The acidity of the carbonation contributes to tooth erosion, so sipping it quickly with a meal is better for dental health than grazing on it throughout the day.
Parents seeking the flavor profile without the associated risks can consider alternatives like plain sparkling water infused with natural fruit or herbal extracts, or unsweetened herbal teas. Encouraging water and plain milk as the primary drinks helps establish healthy habits and ensures children receive necessary hydration and nutrients.
