Good discussion of how hard it is to find data on the safety of things from cars to food to investments. Goes into great detail about how to make interpretable ratings or labels, and what organizations should coperate to do them.
Authors prove own point by missing out on key data on several topics, and merely quote dogma. For example, the supposed dangers of "sodium" meaning sodium ion or salt (pp21,84,111) ignore key data that salt intake affects people both ways, and 10g/day is not that dangerous. See Elliott P et al. (1988). Intersalt: an international study of electrolyte excretion and blood pressure. Results for 24 hour urinary sodium and potassium excretion. British Medical Journal 297:319-328.
Authors quote dogma on high-fat foods and the supposed dangers of saturated fat (p33,53,84,111). See Enig M, Know Your Fats, 1999; Allan & Lutz, Life Without Bread, 2000; Ravnskov U, The Cholesterol Myths, Colpo A, The Great Cholesterol Con.
Authors cite fiber as a good thing (p88), but studies show some forms are beneficial for some conditions in some people, not nearly all, and many people are worse off with higher fiber intake. See Montonen J, Knekt P, Järvinen R, Aromaa A, Reunanen A (2003). Whole-grain and fiber intake and the incidence of type 2 diabetes. American Journal of Clinical Nutrition 77:622-629; Fuchs CS, Giovannucci EL, Colditz GA, Hunter DJ, Stampfer MJ, Rosner B, Speizer FE, Willett WC (1999). Dietary Fiber and the Risk of Colorectal Cancer and Adenoma in Women. New England Journal of Medicine 348(3):169-176.
Authors treat Material Safety Data Sheets descriptions of chemical hazards seriously. Try looking up salt, sugar powder and toluene MSDSs. You will see how hazardous these valuable substances are made to look. Then look up the sheet for bromine, which is really dangerous, and see that it is presented in much the same manner as toluene.
Authors call "speeding" a major cause of traffic crashes. Using the definition that "speeding" is driving faster than a posted speed limit, it is obvious that doing so on a road with light traffic in daylight is not dangerous and may prevent boredom. The definitive work was done from 1958-63 where the P. I. was Dr. Alfred L. Moseley working from the Harvard School of Public Health under a USPHS grant, found that fatal and serious crashes had multiple causes, including vehicle failure, weather, road hazards, driver error, but "speeding" was not one of them.
The authors seem unaware of the corruption at many of the government agencies. Just to pick on the FDA see Cohen JS, Overdose, 2001; Haley D, Politics in Healing, 2000; Moore TJ, Prescription for Disaster, 1998; DeGrandpre R, The Cult of Pharmacology, 2006.
Minor fussing over formats and inputs will not give us the clear disclosure we need because of the overwhelming corruption of responsible agencies as well as vendors.
