He is 8 now and minor amounts of annatto, by accident, do not seem to trigger it. We taught him what to look for and avoid anything orangish in color without asking us. I do have a friend whose nephew throws up when he has annatto, but I haven't come across the stuttering connection. I should amend my comment above, we ruled out dairy as a cause given the milk, yogurt, kefir as well.

Yeah annatto seems to be really problematic for many people.

Ruled out as causes of the issue or excluded from his diet?

[lymeeducator]

We try to exclude it from his diet and minimize it in the house, although he's shown no serious anaphylaxis from it. Typo above, he is 7, not 8. At some point trials for food additives would be helpful...for everyone. I certainly cannot speak to all of the stuttering scenarios, but avoiding a few is better than nothing.
