The reason for the update in calorie counts is not because the bars have shrunk or that ingredients have been changed to something else like air. Instead, a more indirect method, called the “Atwater system,” has been the typical way to determine calorie counts for food labels. In other words, the Atwater method may be overestimating the energy content or calorie counts of almonds by 32%. Will new calorie counts convince you to lower the bar, the snack bar, that is, into your mouth? The new tree nut calorie counts may not really affect snack bars that don’t have nuts as a more dominant ingredient.
