This article provides a lot of background and a lot of links related to the problems related to finding easily accessible sources of good food --- their short-hand way of saying "food from a specific farm, that you know how it was raised."
Much of the background to this article is related to the work of Weston A. Price, a pioneering nutritionist from the 1930s: "Dr. Price traveled the world studying societies who for generations had withstood the onslaught of modern degenerative diseases like tooth decay, diabetes, stroke, cancer and coronary heart disease. ... He also noted that the distinguishing characteristic of all these groups, regardless of the actual specifics of the diet (which varied greatly depending on geography which affected the availability of food), was the daily use of raw animal foods of some sort, without exception. And in a further politically incorrect observation, Dr. Price commented that the premier health food around the world was…butter!"
This sounds somewhat different from what we hear today, huh? The article goes on to discuss the problem of getting raw milk. We can buy raw beef. We can buy raw eggs. Why can we not buy raw butter? Not surprisingly, much of the answer goes back to bad science, money, and the government getting involved when it shouldn't.
This article is a really interesting read.
