Legend Has It . . . How Diabetes Was Discovered and How That Makes Me Fat

The German physiologist Oskar Minkowki was the first person to identify the role of the pancreas in diabetes.  Legend has it that on a momentous day in 1889 Oscar  noticed that urine collected from his pancreatectomized dogs (dogs that had surgical removal of their pancreas) attracted a very large number of flies.  He is said to have "tasted" the urine and to have been struck by its sweetness.  (Only in 1889 could you get away with tasting dog urine.)  He then made a very astute observation and realized that the pancreas controlled blood sugar concentration and was a key factor in diabetes mellitus.
Thirty years later, Fredrick Banting and Charles Best identified insulin as the key hormone produced by the pancreas controlling the level of blood sugar.  However, what Oscare Minkowski couldn't taste was the very high level of acetone in the urine which is produced by the liver in the conversion of fat to ketone bodies.  Had Oscar lost his sense of taste, instead of noting the sweetness to the urine he might have noted the pungent smell of acetone.  He would have then concluded that the removal of the pancreas causes fatty acid metabolism to go awry.  He then would could have extended his hypothesis and concluded that the preeminent role of insulin was not in the control of blood sugar alone, but in the control of fat metabolism.
We have become fixated upon the function of insulin and its effect upon diabetes, and in doing so, we have neglected the fact that insulin has even greater effect upon the storage and use of fat and protein in the body.
A series of discoveries from the 1920s-1960s let to a revolution in the understanding of the role of insulin in fat metabolism.  At that time, fat was assumed to be relatively inert and carbohydrates were seen at the primary fuel for muscular activity (which is still commonly believed today).  The belief was that fat is used for fuel only after being converted in the liver to suspiciously toxic ketone bodies.  Forty years of research overturned this assumption, however, it had no influence upon mainstream thinking about fat gain and obesity.  In 1973 when all the details of fat metabolism had been worked out, Hilde Bruch, the foremost authority on childhood obesity, stated "it is amazing how little of this increased awareness . . . is reflected in the clinical literature on obesity."
JAMA just released it's compendium on obesity research and the simple science of insulin's effect on fatty acid metabolism is STILL being ignored. Instead, main stream medicine is starting to push patients toward a very expensive and risky gastric bypass surgery. This scares me.
Hippocrates said, "Let food be your medicine and let medicine be your food."  The body responds with hormonal effect to what we feed it and the science explaining this has been ignored. We have been brainwashed with the dogma that the "calorie is king."

two days after trans fat ban

Based on this we are now legislating food behavior.  New York has now banned trans fats by the New York City Board of Health and has legislated all soda sizes to no larger than 12 oz. We are creating health policy on bad science.  Let's go back and look at the science before we let our legislators start cooking for us, or soon our grocery stores will look like our government run school cafeterias offering school lunches.
