% Description:        Results of a survey of 40 food items claiming to be "lite," "reduced-calorie," "low-calorie," "diet," "low-fat," "no-fat," or "health" foods.  Each food is classified based on its distribution as either nationally advertised, regionally distributed, or locally prepared.  
%      The researchers measured the caloric content of each food  by bomb calorimetry, and converted these readings into an estimate of total metabolizable energy (the type of energy the calories on a food label are supposed to reflect).  Finally, they calculated the percentage difference between the measured calories and the labeled calories for each item and per gram.
