Calorie counts on labels can be inaccurate
Do you find yourself checking every food label for calorie counts? It turns out those totals may be inaccurate, according to researchers from the U.S. Department of Agriculture's Human Nutrition Research Center. Packaging labels may overestimate the number of calories a product has, as the amount of pounding, slicing, mashing and even chewing can change how many calories people actually absorb. Some foods are not digested entirely, where the body does not use some of the "stored" calories in a particular food. People also expend some energy during digestion that could change the caloric intake from a product, according to the research
The way that nutrition facts are tallied dates back more than 100 years, and scientists back then did not take these factors into account when defining a product. Though the differences may be small, the researchers found that almonds, for example, have 20 percent fewer calories than reported and that some foods' calorie counts can be off by as much as 50 percent.
