Edit: Took out my personal story as it muddles the question. This UC article states that red meat can cause inflammation. Also googling around many sites come up that confirm this. I know that many of the meat studies are flawed so I was wondering the Paleo take on it.
From the article
"Using specially bred mouse models that lacked the Neu5Gc molecule -- mimicking humans before the molecule is absorbed into the body through ingesting red meat -- the researchers induced tumors containing Neu5Gc, and then administered anti-Neu5Gc antibodies to half of the mice. In mice that were given antibodies inflammation was induced, and the tumors grew faster. In the control mice that were not treated with antibodies, the tumors were less aggressive
Others have previously shown that humans who take non-steroidal anti-inflammatory drugs (commonly known as NSAIDs) have a reduced risk of cancer. Therefore, the mice with cancerous tumors facilitated by anti-Neu5Gc antibodies were treated with an NSAID. In these animals, the anti-inflammatory treatment blocked the effect of the Neu5Gc antibodies and the tumors were reduced in size. "
So, like, duh more inflammation means more cancer, but it doesn't follow that more NeU5Gc molecules means a significant amount of inflammation. They used anti-inflammatory drugs and then there was little effect. Well I don't know about drugs but I have anti-inflammatory faculties and they are called anti-inflammatory eicosanoids, and furthermore my immune system makes it own anti-bodies and communicates properly from the second the pathogen is detected. In the first example they basically just let inflammation run wild, but in the human body when all is right and our tissue HUFA isn't distorted inflammation turns on quickly and then turns of expediently, little harm done.
It should be noted that we ingest tons of stuff that needs to be attacked by the immune system every day.The pathological things we ingest are going to be those that undermine our body's ability to work properly, like omega 6 oils or wheat lectins. Or that replicate like an infectious disease.
I may be wrong. I know our biochem experts will be along eventually, but I just think it's naive to extrapolate sustained inflammation in a weird case of mice with injected antibodies to the highly-elegant natural inflammatory cascade. What I do know is that I eat a fair bit of meat and have very low c-reactive protein.
