Why do children not seem to like healthy food?

celebrate treats: I’m not sure I would agree that kids don't like good food but do agree they can drive you nuts over their requests. I think we all celebrate treats more than average fare we eat & kids are no exception. Since the average toddler only eats robustly 3-5 days a month, their picky nature is often bypassed if you offer their favorite. If the kid is growing well and plays hard stick to the good foods.

Picky eater: Most kids don't even recognize healthy vs not healthy. They recognize taste. Seriously, which would you rather have, a cookie or a green bean? Just keep introducing all new foods, neutrally. Hide veggies, like blend a zucchini, and add to spaghetti sauce. Encourage one bite. Only give junk as a special treat. If they totally reject them, give them a multivitamin. Just keep trying.
