Reason for eating only snack foods

What could cause an otherwise normally adjusted 6 yr old to refuse all cooked foods?  Eats peanut butter, but only one brand..some fruits, string cheese
Could it be supersensitivity to taste/smell?
Thank you

Probably not, though it wouldn't hurt to arrange an occupational therapy evaluation for the purpose of evaluation the presence of any sensory integration problem. As long as the child is growing and developing well, such limited preferences is not a problem.

I don't mean to mean but it's probably your fault when they were younger did you cater to what they wanted to eat? I tell my daughter if you don't like what's for dinner then don't eat. You aren't a restaurant if you do this I guarantee it will cure it my daughter is not picky at all and I have done this with her since she was two. It's simply that your child is picky and needs to know who is boss.
