Forgive my curiosity, but do you have an idea why? I'll assume it was not the jerky, as everyone can eat that.
it's not your curiosity, but your condescending attitude that should be requesting forgiveness.. apparently i am not part of the 'everyone' you speak about!
i have made jerky from the same meat that eaten fresh is health-improving and digests fine. the lowest temperature on my dehydrator setting is 85 degrees F (technically 'raw'), that's what I used. the fat i used is not actually rendered tallow, but set at 85 degrees F for an hour or so to get mushy and then blended with the lean. this is the same way i eat extra fat today when i'm in the mood for extra fat, only without the blending part, and i digest that just fine. a surprise to me as well, but it's NOT the fat. the dryer the meat, the worse my symptoms... and they are horrible! again, this is the same meat that is health promoting fresh and even aged is better i have found.
i love hearing everyone's experiences on this forum, but your post attribute what has been successful for you to literally 'everyone'... that's not fair!... it's not fair to newbies... it's not fair to people who read here trying to learn to rebuild their health, and it most certainly is not fair to me!
