Nutritively sweetened beverages (NSBs) (eg, sugar-sweetened beverages, soft drinks) seem to have become a leading contender, and the surrounding dialogue has become contentious, evoking scientific, clinical, and sociopolitical questions.

The key question is whether reducing NSB consumption will help prevent the onset, reduce the prevalence, or contribute to the management of obesity. The controversy hinges on the strength of the current evidence. Clearly there are other important issues, such as potential NSB effects on overall diet quality, dental and bone health, glucose tolerance, hydration, quality of life, the economy, . . .
