I once knew a family with eleven children who lived about forty years ago in an isolated area of Maine before food stamps and convenience foods. They seemed to live most of the year on nothing but home-baked beans and the milk from their cow. They were all magnificently, bloomingly healthy. They obviously knew how to use milk right. p.87 Keeping a Family Cow (rev. ed.) by Joann Sills Grohman (the book was originally published in 1975)
I couldn't help but think that perhaps this sort of people could have been studied to great benefit by Dr. Price. Maybe he didn't know about them? Or perhaps because it's just one family, it's not a big enough sample. Anyway, being financially poor is not a prescription for poor health, so long as we eat properly!
