In 2007, Varitanian, Schwartz, and Brownell examined the relationship between carbonated soft drinks and health outcomes. Their research highlighted that regular consumption of these beverages contributes to increased energy intake and body weight. Since most commercial soft drinks contain large amounts of sugar but virtually no essential nutrients, they provide "empty calories" that can easily lead to an energy surplus. For example, a single 12-ounce can of soda contains approximately 150 kilocalories, all from added sugar, without any significant vitamins, minerals, or protein.
Fortunately, studies indicate that reducing soft drink consumption can be an effective strategy for preventing and managing obesity. Research from the United Kingdom and other countries shows a clear link between lower soft drink intake and improved weight status, suggesting that replacing sugary beverages with low-calorie alternatives or water can have a meaningful impact on overall health.
The increase in soft drink consumption over the past decades is influenced by several factors. Heavy advertising campaigns have promoted these beverages, while lifestyle changes, such as eating more meals away from home, have made sugary drinks more accessible. According to the National Soft Drink Association, soft drinks account for roughly 7 percent of the average person’s daily energy intake in the United States. On average, Americans consume about 56 gallons of soda annually—nearly six hundred 12-ounce cans per person. Consumption is highest among males aged 12 to 29, who may drink up to half a gallon per day, totaling around 160 gallons per year.
Given the clear connection between sugary beverages and obesity, reducing soft drink intake is a practical and effective step toward better health. Public awareness, healthier alternatives, and policy measures can all help shift consumption patterns and reduce obesity risk in the population.
