<human>: So I went to a naturopath with my parents when I was in 6th grade. I was diagnosed with Autism a year before. My parents wanted to fix my behaviour so they went to see a naturopath. The naturopath  thought that we could do a gluten exclusion diet and concluded my bad behaviour was due to gluten intolerance (non celiac)

 After talking to my psychiatrist two weeks ago, I found out that my parents and the naturopath didnt' even properly execute the diet. They only did 1 test period, not 3. They didn't ask me for my feelings of my body pains/aches. They just "observered" my behaviour. 

Now they've been feeding me gluten growing up. I had gluten filled granola bars, rice krispies, pringles, etc for snacks and I never misbehaved. But when I did eat some gluten for  a "treat" (I don't even understand how a naturopath said it's okay to eat gluten sometimes when I "was" gluten intolerant), once in a while I'd have an episode and then their belief in my gluten "intolerance" was confirmed again.

Over the years, they learned that the gluten filled foods I've been eating have gluten so my diet now is 95% gluten free. There are some things such as california rolls that I eat in front of them since they don't know california rolls havegluten.

My goodness I just want to make myself a jam and peanut butter sandwich again but my parents won't let me eat gluten at home. It's okay, i buy sandwiches outside of my house but...

How do I get my parents to believe in actual medical science? They are firm believers that I am gluten intolerant..
 I told my dad right after I went to the doctor and he still didn't believe me.

Give me the gist of the text in a nutshell
<bot>: parents believed I am gluten intolerant. I'm not. they got mad when I confronted them and now they are worried.
