BTW, where did you come up with the fact there are no studies about the positive effects of a plant based diet???
A simple google search brought me numerous, credible studies that a plant based diet can reverse diabetes, reduce cholesteral,
improved digestion, and reduce RISK of cancer..note the word risk.
I think you misunderstand what I said. Specifically, I said that there are benefits to your health if you consume less meat and more vegetables. However, there is no evidence to show that giving up meat completely is of any further benefit. Even if there were such studies, they wouldn't be level 1 studies.
Your sweeping statement is clearly an opinion.

I don't know why Americans look down on "opinions" and "theories" as if it was something I pulled out my bottom end
