It's hard for me to understand the whole soda phenomenon in Canada and the US. Is it as addictive as cigarettes? Does it make you crave for more? Or it simply tastes so good that you can't get enough of it? Why not eat a bunch of apples instead (if you don't care about the amount of sugar you consume)? Wouldn't they taste better?
A couple of factors that I can think of: 1) Sugar is addicting, and there is significantly more sugar in soda than other drinks [Google it] 2) Soda is very refreshing. This is important in warmer climates. If it is 98 degrees outside (37C), an orange Fanta does a much better job of making me feel better than just water 3) Soda is available everywhere and is the de-facto drink with most meals. Just like Italians drink…
typical grape juice has 50% more sugar than Coca-Cola. http://en.wikipedia.org/wiki/Juice
Orange juice 170 calories from sugar vs 150 for cola (12 oz) http://www.hsph.harvard.edu/nutritionsource/how-sweet-is-it/
Googling "sugar in apple juice" turns up 170 for 12 oz as well.
