There are some interesting topics in the UK report, and there are some that
appear to contradict the Paleolithic/evolutionary theory of nutrition, such
as "Other key issues include the possible importance of cereal foods in
wholegrain form." It appears the report mainly looks at foods individually,
rather than developing an underlying explanatory model, as Tanchou and Boyd
Eaton did. Until scientists recognize and test the Paleolithic nutrition
model, or develop a better one, their efforts in nutrition will be stuck in
the current trial-and-error, hit-or-miss mode. Progress is being made in
this way, but at an excruciatingly slow pace, with one step backward for
every two forward.

Your hypothesis fits well with Paleo nutrition, Ron, and targets some of the
most harmful foods.
