It turns out that calorie content in foods can differ by 30% if to compare it with the figures indicated on the package. While estimating caloric content of the products, the companies do not include the energy value of dietary fiber, which is 5% of the total calorie intake.

For example, a person who eats cereal for breakfast every day does not think that instead of calories stated on the package, he also consumes extra calories contained in fiber as the most essential element of cereals.
