Nutrition Syllogism 21. July 2009 William Davis (21) What do you think of these chains of logic?Cyanide is a potent lethal poison; carbon monoxide is a less lethal poison. Therefore: plenty of carbon monoxide is good. Having uterine cancer is a bad thing. Having uterine fibroids is a less bad thing. Therefore: plenty of uterine fibroids are good.These are obvious examples of seriously flawed logic. Students of logic and philosophy will recognize the above erroneous sequences as examples of the twisted arguments often used to persuade an argumentative opponent of the logic of a premise. As long ago as 335 B.C., Greek philosopher, Aristotle, recognized the pitfalls of thinking in such arguments. You think we’d know better by now. Try this one: White enriched flour is a bad for health; whole grains are less bad for health. Therefore: plenty of whole grains are good for health. Ouch! In the 1960s, we all ate hot dogs on white buns, white flour Wonder Bread® sandwiches, Mom made cookies and cupcakes with white flour. Then, during the 1970s and 1980s, clinical studies were performed demonstrating that whole wheat and whole grains reduced colon cancer, high blood pressure, diabetes, and heart disease compared to white flour. In other words, add back fiber and B vitamins and health benefits develop: No argument here. Therefore: whole grains must be good for health. Further, lots of whole grains?unlimited quantities of whole grains many times per day, every day?must be even better. Even the USDA says so on their nutrition pyramid, with 8-11 servings of grains per day, 4 of which should be whole grains, at the widest portion of the pyramid. But what happens when you follow this logic through and fill your diet with whole grains?Look around you and it’s easy to see: Appetite increases, people become obese, blood sugar increases, diabetes develops, HDL cholesterol plummets, triglycerides skyrocket, inflammatory patterns (e.g., c-reactive protein, or CRP) increase, small LDL (the number one cause for heart disease in the obese U.S.!) shoots through the roof.I would no more fill my diet with “healthy whole grains” than I would close my garage door with the car running.
