It was mentioned earlier that the energy value of the product, which is marked on its packaging, is quite relative, and based on these numbers when making diet is not recommended. The fact that the company, estimating the caloric content of the product, does not include in it the energy value of fiber. And this is 5% of the total calories consumed, writes The Telegraph.
For example, a person who daily eats for Breakfast muesli, don't even think about that, instead of printed on the package of calories, it is additionally consumes more and hidden calories as fat in the granola contains the most. Protein products can contain up to 20 percent fewer calories than specified by the manufacturer. A further and added modifying calories during the processing of a product.
According to Dr. Geoffrey Lisa, these fluctuations can sometimes be 30 percent, so as to digest raw foods, people spend more energy. Thus, people use actually more calories than they think. Recall that the normal calorie calculation is made on the basis of proteins, fats and carbohydrates in the product.
The old system of counting calories has been based on that one gram of protein or carbohydrate contains 4 calories. Per gram fat - 9 calories. A few decades ago nutritionists have found that a gram of fat contains 2 calories. Every day people need to eat food, fiber content which should not be less than 18 grams. Thus, this gives about 250 extra "nepatsfan" calories per week.
Already last year in Europe entered into force the law, according to which companies were required to include the calorie fiber, but a few still follow these rules. In addition, it was recently found that a calorie is 3.2 grams of protein calories.
