We were reminded of this on a recent visit to the Hopkinton State Fair in New Hampshire. Some of the foods available from the vendors could rightly be described as homicidal. They had taken the least healthy foods that science has ever produced and found a way to more than double the calories without adding even a single useful nutrient.
All of those bright colors and food additives sheathed in oily breading got us wondering: exactly how many calories does deep-frying add? We knew that frying was bad, but we wanted to know how bad. That question turned out to be far more difficult to answer than we imagined.
