Gatorade, Poweraide, and Whateveraide can be very expensive.  In reality they only contain some sugars, electrolytes (sodium, potassium, and choloride), and artificial flavors and colors.  Nothing special really.  Because I am cheap, I have created a substitution that compares quite well with Gatorade.  Check it out:

Per 8 ounce (1 cup) serving	Sherwoodaide	Gatorade
Total carbohydrate	11.5 grams	14 grams
Calories	43 kcal	50 kcal
Sodium	110 milligrams	110 milligrams
Potassium	33 milligrams	30 milligrams

Recipe

1 cup     sugar      
3/4 tsp   salt
1/6 tsp   salt substitute (Nu-Salt)
2 packs  Koolaid or other drink mix
Mix with water to fill a 1 gallon milk jug
Shake the jug vigorously (make sure the cap is on tight)

 

Tips:

1)  Use a funnel to get everything into the jug.

2)  You can prepare multiple batches by mixing everthing except the drink mix in a ziplock bag.  (If you mix in the drink mix, it will clump)

3)  I like Koolaid orange, grape, and lemon-lime the best.  Also, GreatValue Lemonade from WalMart is very good.  I don't like the Koolaid lemonade or lemonade combos very much.  Try some and see what you like.
