So you're basically a science denier since the same statement can be said of virtually every scientic papers. I guess you should visit the academy of nutrition and dietetics, which represents over 100,000 credentialed practitioners, and tell them they don't know how to conduct a valid scientific study.
But the bottomline is: why would anyone care what other people are eating?
Because the unnecessary suffering and killing of sentient beings is involved. Just so you know, pigs are as intelligent, emotional and cognitively complex as a 3-year-old child. On every front (ethics, environment, nutrition), I really don't know how a sane, humane and well-informed person can be in support of the meat industry.
I think I made my point. That's it for me guys.
