what foods make you breakout?

Miss
So I've been battling acne for 8 years and have tried everything I could think of, switched 3 dermatologists, been on antibiotics for way to long and nothing worked, a lot of different things I've tried helped temporarily but that's it. I've finally started thinking maybe it's something I'm eating and to my amazement I've noticed a change since I stopped consuming dairy products about a week ago. So help me out, my derm says food is not related and I disagree, has anyone done an elimination diet and found out what foods cause you to breakout?
