There once was a time when the term "juice cleanse" wasn't part of our national lexicon. When a Red Bull was something you'd expect to find on a farm, not on a store shelf. But companies keep launching new drinks because Americans keep guzzling them. Beverage World estimates that per capita consumption of nonalcoholic beverages (not including water) was about 116 gallons in 2010.

Many drinks are nothing more than a blood sugar spike waiting to happen. But sometimes you need a little flavor or (gasp!) fizz that water can't provide. So what then? "Keep it simple,". "Stick to natural ingredients, and use a small piece of fruit-about 60 calories-as a reference for how much is reasonable to consume at once."
