My first reaction is that when we eat a refined SAD, we don't have room for the other "traditional" foods. My second is that a lot of the WAP stuff we can find evidence for here in this country. Going to other cultures to learn often makes things clearer when you bring the knowledge back home. And we can see upward trends in heart disease, etc. and chart those right next to the increased use of industrial foods. I have a belief that is certainly shared by many that those side-by-sides are causal, not correlative.
However, my other thought is that this is starting to feel like a Nourishing Traditions discussion rather than an oil-pulling forum offshoot! Sorry for my role in this. I am not sure how to cross-post there, but any WAP-related stuff should probably begin again over there! We do talk a lot about teeth here....and dentists, that is for sure!
