Page has shown a direct relationship between high blood sugar levels and calcium levels and an abnormally low phosphorus level. This situation occurs when the insulin level is too low. His studies with many diabetic patients showed that the blood sugar, calcium and phosphorus levels improved with a diet of mostly animal protein and fat and fresh vegetables, that is eliminating all high glycemic foods, fructose, caffeine and alcohol.
