Harvard Study: Obesity increases significantly with each
daily serving of sugar-sweetened soft drink. Soft drinks currently are the leading source
of added sugar in the daily diet.
“It is not uncommon for teenagers to receive 500 to 1000 calories per day from sugar-sweetened drinks.” (David Ludwig, coauthor)
(Gortmaker, S., & Ludwig, D., (2001) Harvard School of Public Health)
