Western diets have more meat and less plant material. Meat consumption (and plant consumption) isn’t boolean-valued, unlike (for example) vegetarianism.
In this context I wonder whether the problem is meat per se, or the heavily processed nature of much of the meat consumed in the West.
Modern "western" meat is very lightly processed compared to what we were eating a hundred years ago. Refrigeration has removed the need for carcinogenic preservatives and has nearly eliminated stomach cancer.
