I started not drinking sweet drinks (pop, fruit juices) as much as possible several years ago. I also try to avoid foods with more chemicals than recognizable food. Now, I can't eat lots of stuff with preservatives in it. All I can taste is the chemicals. I can't even stand splenda. Not that I'm great with food--I still don't eat enough veggies.
But, I make an exception for Coke with real sugar. Yummmmm.
