Does this square epidemiologically with beef consumption? The countries with the highest beef consumption are in South America (and it's sharply more beef consumption); the countries with the highest colon cancer rates are in central and northern Europe.
It doesn't follow from a correlation that beef is by itself causative; it can be, for instance, beef plus some other X-factor. Somebody is going to point out that South American cattle are grass fed, but European cattle are also more grass fed than American cattle, and yet they still top the leaderboard.
