Is this healthy?

Elisabeth has a recent fetish with healthy food. Before she puts (almost) anything in her mouth, she asks,

"Is this healthy?"

Thankfully the vast majority of the time, the answer is yes - so not only is she eating healthily, but she is learning to recognize a healthy diet. Her follow-on questions are more difficult:

"Why is it good for me?"

That question keeps me honest, and forces me to do some homework. (I recently learned that bell peppers are an excellent source of vitamin C.) Elisabeth is going to keep me healthy!
