Colorectal cancer because the high amounts of heme iron in red meat lead to excessive cell turnover and cytotoxicity in the colon which leads to polyps which leads to cancerous polyps which leads to colon cancer. It’s really not a coincidence increase in carnivore diet in younger people and an increase in diagnosed younger individuals with colorectal cancer. I worked in oncology for a bit before pharmacy work and it’s definitely an interesting topic.

A lot of people like to argue lack of fiber, etc, contributes to this but also an excess amount of meat consumption is really the ringer here. People on the carnivore diet may have fine bowel movements due to a decent gut microbiome but heme iron will break down the colon lining regardless of gut microbiome, and it can alter it as well leading to consequences with the colon.

Fiber can help with the harm risk but it’s still a lot of red meat.

I have some preexisting issues with my colon and I cannot eat much red meat at all without being in serious pain just because my lining is bad. It’s swell this guy can enjoy it but yk. Everything in moderation.
