Is there a specific blood or saliva test which can pinpoint what food allergies you have? Or intolerances or whatever term. I suspect certain foods that I already avoid but I think I'd get more piece of mind knowing for sure...and are these reliable.
so far the foods I know cause break outs are
Dairy, even small amounts
Avocado
Certain oils for frying/ fried food
Too much sugar, more than a few pieces of candy or a cupcake or a brownie
MSG and instant flavor granules

Ones I suspect are
Watermelon/ melon
Banana
Eggplant
Kiwi
Plums
Soy...????big unsure here.
Sugar substitutes
Coffee
Chocolate.
