One nation, under Pepsi ... or Coke. When it comes to soda, 48% of Americans have at least one every single day, according to a new Gallup poll. The remaining 52% drink zilch, but among those who do reach for a pop, they drink an average of 2.6 glasses a day, with 7% of Americans reporting having four or more. It's the first time Gallup has asked about soda in its annual Consumption Habits poll, which found that, America's nearly 13,000 Starbucks notwithstanding, coffee consumption really hasn't budged since 1999—but it remains our liquid stimulant of choice. Some 64% of people reported having at least one cup, up just a hair from 63% 13 years ago.
