I have not read her book but I do frequent the Weston Price Foundation website and am a true believer in a lot of the old traditonal ways of eating because that was how we ate for the first 12-14 years of my life. It didn't help my allergies unfortunately, but for the first 12 years of my life I did not experience a cold, flu or any other illness besides the mumps and the red measles. Didn't get chicken pox, german measles or any other childhood or other diseases and we lived in a very poor, immigrant area. Mom bought raw milk from a local farmer which we drank as is and also let sit on the top shelf of a kitchen cupboard until it soured. This was one of my favorite drinks as a child - sour milk.
