Yes to all of Suse and Fairyrae
Conventional wisdom can't even get its "staple food" right. Like you can find studies where diabetics eat brown rice and bread and it isn't so antagonizing on blood sugar compared with white stuff, and you can find epidemiology where those who ate more whole grains and less white rice and flour tended to be healthier (likely because they also ate less of the other junk food and perhaps exercised and got sufficient nutrition, didn't smoke, etc), but assuming someone is eating a primal diet and generally healthy I would totally go for the white rice/bread to minimize gut irritation.
And reality comes crashing down around us!
Stabbing conventional wisdom in its face.
