And this is snake-oil-salesman-eqsue. It's an understanding with no reason why it should be the understanding.
A lot of people understand why lowering cholesterol in your blood lowers your risk for a heart attack. The mechanisms that underlie the process are understood.
But cancer isn't as easily understood as "that buildup in your bloodstrem breaks off a piece and cuts off blood flow to the muscles of your heart."
It's more of, "as your cells rebuild themselves, they don't do it right and become cancer instead."
You could say that it's because of a high redmeat low fruit diet, when it could really be because of a lower fiber diet, or because of a high exposure to preservatives, or something else.
I'm not discounting the studies, I'm just discounting the claim that "studies show a diet high in red meat and low in fruit runs a markedly higher risk of getting cancer is reason enough to say eating steak/chicken on a 2 night cycle will probably get you colon cancer."
