I had to do a food trial too.. I’m a raw feeder and feed a LOT of variety so a food trial was a must. I eliminated EVERYTHING she had been exposed to in the past and started feeding her raw ostrich as the protein and a novel starch and gave her freeze dried goat for treats.. She ate this and only this for 6 months. At the end of the 6 months her sysmptoms were a thing of the past. I then introduced a new food about every 4 days to make sure there wasn’t a delayed reaction. Turns out she is allergic to beef bone (which I have to watch in whole food supplements as well as her raw diet), goat dairy, cow tripe and barley. I believe the lectin proteins in the barley damaged her gut allowing the proteins from the other foods to get into her bloodstream causing the allergic reaction. Oddly, she has no issue with what we think to be “protein” — chicken, beef, lamb, duck, turkey etc.
With Audrey we were sure it was a food allergy because she had symptoms year round and because her eosinophil white blood cell count was high on her blood work (eosinophils can be high with food allergies and parasitic infections). From my understanding, eosinophils are not high in food intolerances however and food intolerances (like Audrey’s to barley) can have the same symptoms as true allergies.
