I have so many food allergies I can't keep count and my DH does a better job than I do. One problem is that they change on me. One time I can eat something and the next time not if I haven't eaten it in a long while. I have all types of reactions and some even cause me to have to use my oxygen. Then there are the ones that swell my tongue and throat. I try to do the rotation and elimination diets. Most of the time I don't have enough foods to eat so that I can stay on the rotation diet. Some of the foods I am not actually allergic to, I can't digest like any type of grain and meats.
I hope you are able to avoid the red dye and anything else that cause reactions. The results are not fun and some are very dangerous.
