Weston A Price foundation is not a reliable or useful source of health information. It is more of a religion, or cult, based on a bunch of anecdotes from Price's travels and dental practice. They never let science get in the way of a good story from their founder.

As with other religions, they get some things right, but I think I'll take my nutritional guidance from the best science I can find on the topic, rather than a 19th century dentist.
