Welcome! All the best in reaching your goals.
With the wheat allergy, I have also been told by a naturopath I may be allergic to it. Same symptoms as you plus constant dark circles under eyes
, headaches etc. Not fun!
Anyway I did some research on the net and depending where you live or where you're moving to there may be shops just selling wheat free, gluten free, dairy free products etc. I know there is one near to me that does, I found it on the net too. You will be amazed at the products they sell that you can still eat, and food stuff that has been modified to not include wheat etc. Very cool!
I'm not sure about fat, sugar etc. content of these foods though so just check that out before you go crazy when you see all the foods you can still eat
I know the modified bread is very high in kJ's(i think) though.
It seems these allergies are quite common these days so thankfully the demand for these type of products are being supplied! Now the cost of them needs working on
All the best, hopeufully you will have no trouble finding allergy free food in the U.S too.
