Every time my daughter brings a gatorade or even one of those new flavored waters, her coach check the label. I know water is probably the best but that can get boring for her. Also snacks are a big question at our gym. I think I send healthy snacks, but she often comes home and says "Coach says I can't have that anymore". She usually takes fruit, yogurt, applesauce, cheese, fruit cups. These are all fine. The problem has been with Nutragrain fruit bars, special K cereal bars, protein bars, and pretzels. These have been labeled "not good". How do I know what is good and what is not?
