So I started drinking juice diluted with 50% water. Way more natural, and fructose is much healthier than sucrose. It worked pretty well for me; YMMV.
Fructose, or fruit sugar, is a simple monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose[2].

After all, they both do the same thing: give you sugar and water, in a good balance for during- or post-workout. (Soda is too fizzy, too sweet.) Obviously, the fruit-juice version is probably healthier.
Gatorade isn't about your mental state, I don't know where the author got that idea. It's about water and energy in the form of instant calories.
Well, the author claims he got that idea from the studies that showed 1) a better effect when gargling with Gatorade than drinking it, 2) a better effect when gargling with sugar water than with fake-sugar water, and 3) mental state differences between the two sets of garglers. Presuming the studies were conducted well (and, to be fair, it's quite a presumption), it would seem to be a compelling case.
