New research provides evidence that proposed taxes on soft drinks may make young people healthier.
The study, which collected food intake data from 12,123 young adults for 20 years, found that with every 10 percent increase in the price of a two-liter bottle, people consumed 7 percent fewer calories from soda. They also took in fewer calories over all.
When people faced an even larger increase — $1 for a two-liter bottle of soda, comparable to a proposed tax in Philadelphia — they consumed 124 fewer calories a day, the study found. The lower soda intake was associated with a drop in weight of more than two pounds — and a lower risk for pre-diabetes. The study appears in the March 8 issue of Archives of Internal Medicine.
