Very true. Sugar is not the entire story of why calorie consumption increased, after all. http://www.usda.gov/factbook/chapter2.pdf http://www.usda.gov/factbook/chapter2.pdf "ERS data suggest that average daily calorie intake increased by 24.5 percent, or about 530 calories, between 1970 and 2000. Of that 24.5-percent increase, grains (mainly re-fined grain products) contributed 9.5 percentage points; added fats and oils, 9.0 percentage points; added sugars, 4.7 percentage points; fruits and vegetables together, 1.5 percentage points; meats and nuts together, 1 percentage point; and dairy products and eggs together,-1.5 percentage point.)" I do think going light on highly processed food (including refined sugar and refined grains), and going light on calorie dense oils and fats is pretty good advice for any diet. But that's entirely due to the impact on calorie consumption, not due to any other health bogeyman.
