from okcfox.com: It takes more change to grab a drink from a vending machine these days and what kids are reaching for isn't just soda anymore. A study from the journal, "Pediatrics," shows a decrease in soda and tea consumption-- and a shift in caffeine culture. Researchers found more kids are reaching for energy drinks and choosing coffee over soda. "I think it's a Starbucks culture, makes coffee accessible," said Penney Edwards, a parent in the Oklahoma City area, "hot coffee, cold, fancy." Findings in the study, "Trends in Caffeine Intake Among US Children and Adolescents," shows coffee consumption more than doubled among children. Coffee accounted for 10% of caffeine intake among children in 1999-2000, but spiked to 24% between 2009-2010.
