Consuming soft drinks from vending machines during school hours has no impact on adolescent obesity according to a new study performed by the Center for Food, Nutrition, and Agriculture Policy at the University of Maryland, USA.

Analysis based on data from two large US government food consumption surveys and data from previous studies performed on the topic, concluded that teens do not drink enough servings of soft drinks from vending machines to make a dent in the their body mass index (BMI).

Author Dr. Richard Forshee said, "…applying a worst-case scenario of soft drink consumption from school vending machines on body mass index (BMI) is minimal…these data show a very modest impact, if any, on adolescent overweight."

The scientists used risk analysis to measure impact, a technique widely used in studies on the risk of exposure to carcinogens, work place safety and food safety.
