Autism: Dairy Free Diet

Since we have gotten the autism diagnosis, we have researched every option to help with Leo’s symptoms and behaviors. The one that seemed like a simple change that could have a big impact was switching off of dairy completely. 


It was a little more difficult than expected because I didn’t realize that the only foods my son liked to eat was all dairy products. Milk, string cheese, mac&cheese, quesadillas, yogurt, ice cream and chocolate. 

The first two days were rough, he was extra fussy and didn’t want anything. I had substituted milk with almond and coconut milk. No cheese at all or yogurt. There is coconut milk ice cream and carob chips (similar to chocolate), so he wasn’t completely cut from everything. 

By day three, we started to see a difference in Leo’s behavior. 

  • He had better attention
  • Willingness to try new things
  • More vocal
  • Fewer tantrums
  • More responsive 


With the results we saw, we were going to stick to a dairy free diet. So we all have been dairy free since October and I can’t go back. I tried having milk and I got stomach aches. It has helped all of our health, not just Leo’s. 

I would highly suggest anyone and everyone to try removing dairy from their diet and see what results they notice. The time it takes to see results vary from person to person. We were lucky to have some results within the first week but it can take up to a month to start seeing a change. And for some, it may not help at all but it is worth a shot. 


I hope this was informational and helpful. If you have more questions or comments, feel free to send me a message!

Love, Cloe 💙
