If you don't like the amount of sugars in Gatorade, try making your own solution from distilled water, salt and sugar and whatever flavorings you want to use (like that Mio stuff, perhaps or Crystal Light). WHO and UNICEF have set a standard for oral rehydation solution (ORS) at about 30 ml of sugar and 2.5 ml of salt for every 1 liter water. You can also drink Pedialyte which you give to infants/toddlers if they suffer from dehydration but is made with less sugar than sports drinks. I know several professional teams use it as well as many boxers and MMA fighters when rehydrating after weigh ins.
However, I think the article is referring to energy drinks (Red Bull, Monster, AMP etc.) rather than sports drinks. I only use these if I'm falling asleep at the wheel because I'd rather have a near inconsequential long-term risk to my health rather than wind up getting hurt in an auto accident or even being involved in a non injurious accident.
