The Weston A. Price website has a refreshingly readable explanation of the causes and management of diabetes, the disease that has become so commonplace in North America:
If we run a marathon every day, a balanced diet would probably include about 300 grams of carbohydrates per day, the amount contained in 20 potatoes or 6 brownies. If we sit on the couch all day, obviously our requirement for energy food will be less. In this case a balanced diet would include only about 65-70 grams of carbohydrate per day. Any more, and our bodies are forced to make more insulin and the whole vicious cycle begins.
The problem of diabetes can be summarized by saying that the western diet has us eating like marathon runners, when in fact most of us simply sit on the couch. When we regulate the carbohydrate intake to match our exercise level, type II diabetes cannot develop, and in fact, I have found that most cases of type II diabetes respond well to treatment when these basic principles are kept in mind. Type I diabetes responds equally well to a high-fat, low carbohydrate diet. In fact, before insulin was available, the only way to treat type I diabetes was a high-fat diet from which carbohydrate foods were completely excluded because the body does not need insulin to assimilate proteins and fats.
