My family has been testing various food items and it was found:
.dressed chicken .peanuts .soyabean oil .cumin
And we used to use these food "daily".
The allergy eruptions, digestive issues went from 100 to 5 starting next day.
This is such a small thing to check but it has saved us as a lot of trouble.
Could you clarify what you mean by "dressed chicken"?
And I'm curious, did all of your family find yourselves allergic or sensitive to all of those things, or is that list a combination that covers everyone while each individual was allergic to one or a few of them?
