Back in the day.. when I ate Paleo.. before I learned about BTD.. I ate tons of chicken and never noted a problem.
Once I stopped for a few weeks and tried to test it again I was immediately ill after just a few bites. I found that interesting since I chunk down lamb and beef like a dog. :-)
More to the point: My wife is an A secretor and she still makes chicken sometimes. I often have to leave the house while it cooks for the smell of it. As a proper B my sense of smell has accelerated 100 times. I can smell something evil across a room now.
