Framework

I'm currently reading "Good Calories, Bad Calories" by Gary Taubes, which is fundamentally one long discourse on all of the diet/disease hypotheses out there, and the relative truth claims of each one. I am blown away by how often misinterpretation of available data is represented as the truth, and by the amount of refuting evidence that is ignored by the nutrition industry. Taubes uses this book to lay out the shortcomings of the prevailing theories on nutrition and disease, and to present the available data/research that runs counter to them.

These quotes set the tone of the book.

"Men who have excessive faith in their theories or ideas are not only ill prepared for making discoveries; they also make very poor observations. Of necessity, they observe with a preconceived idea, and when they devise an experiment, they can see, in its results, only a confirmation of their theory. In this way they distort observation and often neglect very important facts because they do not further their aim... But it happens further quite naturally that men who believe too firmly in their theories, do not believe enough in the theories of others. So the dominant idea of these despisers of their fellows is to find others' theories faulty and to try to contradict them. The difficulty, for science, is still the same." (Claude Bernard, An Introduction to the Study of Experimental Medicine; from Taubes, p.1)

"In reality, those who repudiate a theory that they had once proposed, or a theory that they had accepted enthusiastically and with which they had identified themselves, are very rare. The great majority of them shut their ears so as not to hear the crying facts, and shut their eyes so as not to see the glaring facts, in order to remain faithful to their theories in spite of all and everything." (Maurice Arthus, Philosophy of Scientific Investigation; from Taubes, p.60)

"The thing is, it's very dangerous to have a fixed idea. A person with a fixed idea will always find some way of convincing himself in the end that he is right." (Atle Selberg; from Taubes, p. 122)

"Forming hypotheses is one of the most precious faculties of the human mind and is necessary for the development of science. Sometimes, however, hypotheses grow like weeds and lead to confusion instead of clarification. Then one has to clear the field, so that the operational concepts can grow and function. Concepts should relate as directly as possible to observation and measurements, and be distorted as little as possible by explanatory elements." (Max Kleiber, The Fire of Life: An Introduction to Animal Energetics; from Taubes, p.136)

"Oversimplification has been the characteristic weakness of scientists of every generation." (Elmer McCollum, A History of Nutrition; from Taubes, p.153)

"The suppression of inconvenient evidence is an old trick in our profession. The subterfuge may be due to love of a beautiful hypothesis, but often enough it is due to a subconscious desire to simplify a confusing subject." (Raymond Greene; from Taubes, p.178)

We deserve to be better informed than we are about how our diet affects our health, even if science can only tell us that right now there is no answer (that is more helpful than falsely claiming to know). We can only build on what we know. The idea that we can only save ourselves through medicinal "cures" is suspect of ulterior motives. I'm not against using medicine, but much can be said about the evolution of our dietary habits with hardly any instance of modern diseases until the modern era. There is good reason to believe that the best "cure" for most of these maladies is prevention by way of nutritional choices (i.e. eliminating the foods that have become prevalent: refined grains, sugars, highly-processed and laboratory-manufactured ingredients).
