I've recently watched a rather compelling lecture (embedded below) that even if the facts with associated theory don't hold up, the negative health
correlation stands. Our fellow mammals are for petting and riding. Not for eating or drinking! There may be a reason other apes do not fall victim
to a significant number of diseases and pathogens that impact humans. That reason may be a sugar called sialic acid type-Gc which humans lost the
ability to produce some time during our evolution. We still find it in our bodies however, as it is found in red meat and dairy, and it's a sugar
that tumors thrive on.

I will also discuss my own group’s research on the many genetic and biochemical differences between humans and great apes in relation to cell
surface sugars called “sialic acids” and their implications for understanding human susceptibility to certain infections, unusual features of the
human immune system, the human birth process, and the human brain. I will also discuss our research on surprising findings regarding one sialic acid
called “Gc”, which is found in the great apes, but not in humans. This non-human molecule can be incorporated into the human body from dietary
sources such as red meat and milk, and is also now contaminating biotherapeutic molecules that are produced using animal-derived materials. Humans,
however, have also been found to have antibodies directed against Gc. This could potentially explain certain dietary associations with human disease,
as well as negative reactions to some biotherapeutic products.
From what I've found googling around it looks like poultry and fish have extremely low or nonexistent levels of Gc. A good thing too because
vegetarianism simply does not provide nutrients or fats found in sufficient quantities or as highly soluble a form as in meat.
I'm convinced diet is the primary source of many if not most chronic health problems. Particularly in the West, where we find rancid oils and
concentrated fruit sugars in every aisle of the supermarket. But now it appears there may be a cause for the correlation observed between eating red
meat or dairy products and certain types of cancer or chronic disease.
So, having already eliminated beef and pork from my diet, it's soy milk for me!
