We thank Dr Primark for his letter regarding “The Association of Caffeinated Beverages With Blood Pressure in Adolescents”1 and the editorial by Couch and Daniels that accompanied it.2 Dr Primark noted that Couch and Daniels provided an incorrect estimate of the amount of soft drinks that would be equivalent to 100 mg of caffeine. As stated in our article, we estimated the cola equivalents based on the average amount of caffeine consumed by those who were in the “greater than 100 mg per day” caffeine category. This amount was 146 mg of caffeine per day and, based on the amount of caffeine in a 12-oz regular cola (37.2 mg of caffeine), would be equivalent to the amount of caffeine in 3.9 cans of regular cola.3
