Hi Dana,
You have raised some *very* interesting points. The results of the
ketogenic diets certainly weaken the results of studies suggesting that
meat consumption and associated saturated fat is a cause of cancer.

You might be interested in looking at the articles cited below. The first
two indicate that some proteins from cereals and milk may inhibit our
ability to battle malignancy. Celiac disease provides an example which
identifies those at one end of the spectrum. The second two indicate an
association between cancer risk and cereal consumption. The picture is, of
course, much more complicated than that. I have summarized in the interest
of brevity.
