Second, I found it very dishonest that great pains were taken to show that many advocates and studies of Paleo and other meat based diets were merely the product of bias because "big meat" was influencing them financially. I then discovered that James Cameron and his wife own a pea protein company. Which is one of the main ingredients in meat free "meat". Hmm, they wouldn't stand to gain financially from people going vegan, would they?
Normally, I wouldn't think that would matter too much. But they didn't disclose that and sounds a lot like the pot calling the kettle black.
I think science is pretty settled that we should all have a higher ratio of vegetables in our diet. But humans are unquestionably omnivores so I think Game Changers advocating for a totally animal product free diet is worried more about their ideology and possibly pocketbooks than they are the health of those who watch.
I myself am most interested in what medical doctors (MD's) have to say about the question of plant-based diets, with reference to peer reviewed scientific journal articles. On the one hand, we've got high-profile MD's such as Dean Ornish, Caldwell Esselstyn, Michael Greger, Neal Barnard, Joel Fuhrman, James Lomis and Matthew Lederman arguing for the benefits of a plant-based diet. Can someone provide links to MD's who take an opposing view?
But quick research on Google Scholar points out that it's probably hiding some facts. Like vegans may be healthier but get obese too. It helps with diabetes and insulin resistance, but not completely. Gladiators may have been a little fat, as a form of armor.
What's interesting is a quick search turns out that lacto ovo vegetarians do a little better than vegans. So "animal products" might not be entirely bad.
They do a once off 'experiment' with a sample size of 3 and claim that it's conclusive evidence that eating meat "is bad". Yikes.
You can watch the debate on Joe Rogan and draw your own conclusions https://www.youtube.com/watch?v=s0zgNY_kqlI . The only thing I can equate the director of that movie is Donald Trump, a total demagogue.
Next I'd read "The Engine 2 seven-day rescue diet" by Rip Esselstyn. If you a more in-depth treatment, try "How Not to Die" by Michael Greger, MD. If you want scientific journal articles, I recommend the work of Caldwell Esselstyn. MD and Dean Ornish, MD. Dean Ornish's TED talk is also a good reference.
