Recipes for Sports Drinks?

A friend took her 13 year old daughter to the Dr. for some strange symptoms she was having. The first thing he told her to do was to stop drinking sports drinks such as Gatorade, etc. It is very hard on the liver, causes abnormal blood tests & takes a long time to get out of the system. He said the only people who need them are people who train 8 hrs per day. The average athlete just needs water & fruit juice. You might check with your Dr. about it. It looks like you're doing the right thing by looking for a recipe with natural ingredients.
