A report issued on June 15th by the CDC in the Preventing Chronic Disease journal found that following a policy passed in June 2004 restricting the sale of sugar-sweetened beverages in Boston Public Schools, students reduced the consumption of sugar-sweetened beverages significantly.

The study reports that the reduction is equivalent to 45 kcal or a 19% decrease in reported consumption of sugar-sweetened beverages. This reduction accounts for 25% to 40% of the total “energy gap” – the calories in excess of a person’s daily energy needs – that is believed to contribute greatly to the continually increasing average weight of youth across the United States.

The Boston Globe points out that this compares favorably to the national average of reduction in consumption from 1.74 to 1.66 sugar-sweetened drinks every day.
