A popular misconception is that girls who are athletes need a lot more protein than those who are not. KidsHealth says that a teen athlete can get all of the protein she need through a healthy diet, and eating foods such as meat, poultry, fish, eggs, dairy products, soy, nuts and legumes.

If your daughter is vegan, she may not be getting enough protein in her diet. If she is vegetarian and eats a variety of non-meat animal products, she is more likely to consume adequate protein. Vegans should be sure to eat nuts, tofu and other soy products, beans and whole grains. If you are concerned that she is not getting enough protein, talk to her doctor.
