I had my first allergic reaction to red meat in 2013. My diet currently consists of some form of chicken at every meal, or ground turkey.
It was 6 months of torturous experimentation to figure out why my stomach was burning like lava after every meal. When I had something important to do that day I knew I could eat bread or crackers to avoid a food reaction.
The allergy is rare in my home state so I had to see a doctor from South Carolina to recognize my symptoms and order the correct test.
