I am planning to interview a family friend, Jenn, who has a 7 year old daughter with an autism spectrum disorder called Pervasive Developmental Disorder (PDD). I will be asking Jenn these questions in order to learn more about her/her daughters experiences with the GFCF diet, as well as any other information that may help to answer our research questions. 

Can a gluten and casein-free (GFCF) diet really help to improve the symptoms of autism spectrum disorders?

1. When did you first learn of the possible link between autism spectrum disorders and foods containing gluten and casein?
2. Who was it that told you about the possible benefits of putting your child on a GFCF diet?
3. What have doctors told you about the diet?
4. Have you found many doctors to be knowledgeable on the theory?
5. Have you heard of many success stories with the diet?
6. Do you know how/why gluten and casein affect children with autism spectrum disorders?
7. Can gluten and casein be harmful to anyone or just those who can’t properly digest it?
8. Did you fully commit to the diet at all times?
9. What happens if your child consumes a food containing gluten or casein after being on the diet for an extended period of time? Will you need to start all over?
10. How long does it take to fully eliminate gluten and casein from the body?
11. Was it difficult to maintain the diet?  Why or why not?
12. What are some of the things were you required to do in order to ensure that you were fully eliminating gluten and casein from your/your child’s diet?
13. Were you required to make minor or major changes to you and your child’s lifestyle?
14. Is it expensive to maintain the diet?
15. Is there a difference in the taste of gluten/casein-free foods?
16. If so, did your child notice these differences?
17. Do you shop for organic products as well?
18. If so, why—are there certain products you always buy organic?
19. Does a GFCF diet require special foods or are there a lot of regular foods available that do not contain gluten and casein?
20. Do stores offer a wide selection of gluten-free and casein-free products?
21.   If not, did you have to purchase some of your food from specialty stores?
22.  Was eating out at restaurants difficult?
23.  Do you know of any restaurants that offer special menus offering gluten and casein- free foods?
24. Can you give some examples of foods that contain gluten?
25. Can you give some examples of foods that contain casein?
26. Did you notice any significant changes in your child’s behaviors while she was on the diet?
27.  If so, how long did it take for you to notice these results?
28. Now that you have tried a GFCF diet, do you believe that it has helped to reduce any of your child’s symptoms related to her disorder?
29. If you didn’t notice any changes in your child’s symptoms related to autism, did you notice any other benefits that your child experienced while on the diet, such as her general health, energy levels, moods, etc.?
30. Do you think the foods we eat have anything to do with the reason for so many of today’s children being born with autism spectrum disorders?
