Kids book that would promote interest in different foods for a picky eater (elementary school level)

Hi all.

I have a rather picky eater, but I notice that actually explaining why specific food is useful, he might sometimes try it.

I’m interested in a fiction (story-telling) book rather than plain facts book (we have such one already and use it from time to time as a catalogue) that would touch my child emotionally and help him get interested in different foods. A book that would have information about why certain food is good for our health.

Maybe there is even a series of books that touches different foods. Obviously, veggies is the difficult one, but also proteins.

Thank you.
