Every workout should include some fuel at the end, to provide protein, carbohydrate, and electrolytes for muscle recovery and rebuilding. 

Some runners rely on supplements to refuel.  This is an acceptable form of energy, but "real" food can provide the same nourishment.  Natural sources are also thought to be better utilized by the body than engineered foods.            

One of my favorite post workout snacks is cottage cheese.  The 1% fat variety provides 80 calories per 1/2 cup, 5 grams of carbohydrate (sugar), 450 mg sodium, and a whopping 13 grams of protein!  If you can't stomach the texture, try scooping it up with some baked potato or pita chips for extra sodium and carbs.  Check back for more suggestions, or let me know your favorite so I can share it with the team!
