Have you looked into your digestion?

Maybe some type of leaky gut situation going on, causing your body to create antibodies to things that it really shouldn't be fighting, like beef?

But how do you explain allergies to paleo-friendly foods like meat?

I have friends who have "allergic" reactions to CAFO meat, but not grass-finished/antibiotic-free meat.

Well, first off, I feel for you. Congratulations on having one of the absolute rarest allergies possible. Second, did you get the skin prick test or was it done via blood test? I have gotten a few false positives on skin prick tests, and have heard of other getting them anecdotally, so it might be worth taking positive allergic reactions with a grain of salt. If you aren't getting hives, an itchy palate, or other signs of a immune reaction, it might be worth getting it retested.

Allergies in general have nothing to do with how inherently "bad" a food or item is. I mean, there is absolutely nothing dangerous about pollen or grasses or shellfish or peanuts, but those are some of the most common allergies. I mean, it's possible to be allergic to WATER. A substance can be the friendliest thing in the world, but if our IgE decide it's a dangerous foreign substance, it can launch an immune response. If you subscribe to the hygiene hypothesis (I'd say a pretty good portion of immunologists lean this way now), the response is due to a lack of exposure to, specifically, parasitic worms. Unless you live in a tropical area, or have a contaminated water/food system, it's pretty hard to get some contact with parasitic worms. Not that I'm saying we should run out and find us some raw sewage to throw into the pipes, but I'm hoping on some really cool developments in Europe that show that safe exposure to innocuous parasitic worms will prevent allergies at young ages. Until then, managing allergies through avoidance or immunotherapy (which they will rarely do for food allergies) are the only easily available options once you've developed an allergy.

On the flip side, being allergic to pork and beef doesn't mean you have to give up paleo! There are plenty of other meats and seafoods to enjoy like lamb, rabbit, chicken, turkey, ostrich, horse, oyster, squid, octopus, scallop, shrimp, prawns, salmon, crab, lobster...the list really does go on and on.

I would love the answer to this too. After a blood test I found Im allergic to milk, eggs, wheat and peanuts. The milk and peanut allergy is obvious...My throat and ears start itching a swelling if I eat them. Eggs and wheat I havnt noticed an obvious reaction so I still eat it occassionally.

But considering my allergies are for the most part paleo friends (no milk, wheat or peanuts anyway) Im killing myself over the eggwhite allergy. I used to eat them every day!

I have tests yearly and they are always different and I literally disagree with many of them, they don't always match up. Mind you I feel the testing is also inconsistent because its always a different type, kind test, in a different country in different labs, etc. so never done in the same place or the same test.

I've also learned that some foods are just plain gut irritants and some show up and some don't (ie: nothing for potatoes, rice ...beef and pork always shows but i can eat pork, caseins but not lactose)

The best way to is trust your body, remove it and try introducing things. I also find there is a line of intolerance which is different to an allergy. There is also conditions which can cause you to react to foods but because of imflamation rather than an allergy. Unfortunately it all gets intertwined and difficult to know whats really what. Testing of actual tissue in the intestines, colon can confirm imflamation due to allergies....ok, that test I believed!!!

There are so many protein alternatives it doesn't really matter or should stop you from enjoying food! You just have to wrap your head around it and go for it with a positive attitude and it will all be good!!

Ok I just wrote the longest answer ever and it didn't go through. Here is what I am thinking. I was not tested by a western medical doctor but instead by a Chinese medicine acupuncturist and herbologist who also practices NAET which is a way to lessen or maybe cure food allergies or sensitivities. In my own experience I was tested positive, by way of muscle testing using samples for many specific things, both food and other, by themselves and in combination. It is important to remember that we all have allergies but to differing degrees. Some are so mild, they are unnoticeable and others apparently life threatening. The NAET probably helped some, but some things I just avoid. I was told that I had a combination pork/nightshade vegetable problem which I think accounts for me feeling sick every time I would eat out and have a bacon omelette slathered in salsa! Tomatoes! You get the idea. Yours could possibly be a combination thing? Later I was tested by a nutritionalist using a mail in prick test kit. It matched what I had already been told. When eliminating these foods (and paleo does) I have improved. I. Would look into a few things. 1. You could be allergic to additives and preservatives and not the meat itself. You are only as good as the sample they test you with. 2. It could be only when combined with something else, and by combined I mean exposure within 6 hours or so! This one thing that makes this so complicated! 3. You could be allergic to such a small degree it doesnt matter and you can continue. I would consult someone like I did. I never have done well with western medicine. Just my .02
