Monica used to love eating nothing but cakes, fizzy drinks, burgers, chips and pizza.

Her mum and dad encouraged her to eat other kinds of food, but Monica wasn't interested.

That was until she met a girl called Rachel. Rachel liked eating things like salad. She told Monica all the terrible things that would happen to her if she kept drinking fizzy drinks and eating fatty foods, and never ate fresh fruit and vegetables.

Now Monica eats as well as Rachel. She really enjoys eating this way, and just occassionally, she can still have a treat!
