Most docs I know have said high consumption, especially grilling open fire of meats increases the carcinogenic activities in the meats. Plus sitting down all day doesn't help either LOL...
real hard to pin down cause and effect. I am sure the Lynch syndrome was the main reason my polyp grew when it did (Lynch can lead to polyps that can become cancer in a year), but could it have been also related to too much beer in college and/or later? I exercise 50-60 min/day, swimming and weights. Generally eat fine, drink coffee, etc. Yet still I got the cancer (so again Lynch was driver?). My 70's yr old father who also carries the Lynch gene basically lives on steak/hamburger/any cooked red meat (esp. grilled!), potato chips, and cheap beer. He's had some polyps, at age 74, but nothing else... so again, real hard to pin down cause and effect even if there is a great amount of data showing something can occur (like what Rikimaroo mentions re: red meat and sedentary lifestyle and how they do increase cancer risks).
This study is interesting, but way more follow-up work needs to occur and more data needs to be generated (so hard to control and pin down causes of biological processes in real people, given all the possible external and internal variables). Esp. in the context of the much higher rates of those of younger folks getting it that are not getting it due to some kind of preexisting condition like Lynch syndrome. I do think diet and environment likely play a role and might exacerbate random mutations (and aging-related degenerative changes) when they occur, but I'm not a biologist.
