Watch out for the high-fructose corn syrup, if you drink gatorade for exercise purposes, that crap will hold you back. You're better off getting the powdered kind and making your own.
Exactly. HFCS in any beverage is teh sukk. Sugar dehydrates and can contribute to all sorts of health problems.
A 20oz bottle of store-bought Coca-Cola made Gatorade can be beneficial during or right after an anerobic workout, but it shouldn't be consumed as a primary rehydrator or beverage of choice; a pinch of salt (or powdered workout drink mix) in 20-32oz of water for during and after a moderate to heavy workout as well as taking a once daily multi-vitamin in the morning (or at least 4 hours prior to a workout), and eating meals containing proper amounts of beneficial nutrients will do a lot more good for your body, imo.
