I'd be very interested in reading more about high-meat countries having lower cancer. That contradicts my current understanding, but I'd definitely be willing to revise my position if it turns out meat isn't involved in colorectal cancer.

It's interesting to me that you had such problems on plant-based diets if you were eating balanced meals. I wonder what nutrient you could've been missing? Thanks for sharing your personal experience, though!

(Also, not to steal your line, but sorry for the late reply.)
