That question - in and by itself - gives you away as an American. As a central European who grew up on water, fruit juice (80-60% water thinned) and tea (green, herb and on and off black) it made me chuckle. I have never seen so much soda consumption anywhere on this planet before coming to the US.
Notwithstanding the golden "correlation != causation" adage, I found that only two things are truly consumed in much larger quantities in America than any other country I know: soda and high fructose corn syrup...at the same time being the only country with a 35% obesity rate...hmmmm
Not true. Saudi Arabia is the most obese country on earth, at 70%.
Britain, Australia, and New Zealand are also substantially obese. All of those are coming increasingly close to catching America in obesity, with their obesity levels exploding higher.
The US Government's vast, and continued, subsidization of corn is what led to the creation of HFCS. Makes sense, unfortunately, that the US would be drowning in it.
That's a good question. Back in the old country, people don't drink as much soda but they have another "drinking" problem--beer and hard liquor. That's much worse than soda, but it's a real addiction (alcoholism).
In the other country where I lived a big chunk of my life, they usually drink green tea.
Seriously though, some of the descriptions of culture of drinking soda in this thread make me think of that movie. For last 15 years I had soda maybe 10 times and it was usually like few sips. I just can't phantom a world where soda is what you drink when you are a thirsty or to meals. I don't remember people I eat out with ordering soda to their meals either. It's usually water, tea, coffee, sometimes fruit juice.
I drink far more Coke Vanilla Zero than could possibly be good for someone when at home, and yet when eating out I generally get iced tea with no sweetener. You may know a closet soda addict and not even realize it. :)
