I would not personally.....my degree is in dietetics so I feel I have a good nutrition base as a result.
I think the most important aspects of nutrition and fitness are in the "doing it" aspects and not necessarily providing interactive games to teach it. Children need to learn about eating healthy? Feed them healthy and talk about the food while eating it (like how it is good for them). Children need to learn about fitness? Give them a lot of activity!
Just my 2 cents....
