Right here.
I read this...
This technology is also referred to as "genetic engineering", "biotechnology" or "recombinant DNA technology" and consists of randomly inserting genetic fragments of DNA from one organism to another, usually from a different species.
...and didn't bother reading any further initially. That generalization alone tells me the authors have a poor understanding of the subject material.
Skimming through their sources, I see a Lancet and Royal Society of Medicine, but nothing else noteworthy. Most of them deal exclusively with specific rat and mouse strains, so I would take all the findings with a significant grain of salt - especially as their findings deal specifically with the immune system and hormone regulation. While mice make good general biological models for humans, specifics don't usually carry over directly. Our immune and digestive systems are sufficiently different to inject a healthy dose of skepticism.
This paper reads like an opinion piece sprinkled with citations (none of which actually cite anything, you might notice, but take generalizations from entire papers) to make it look like science. And citing books? Please. Give me reproducible facts or STFU, thanks.
