Energy value of products

When the amount of nutrients that a particular food contains is used, the term "energy value" is used. This term indicates the number of kilocalories that is released in the human body when processing a product. To give the reader an idea of what a single calorie is, it is worth noting that this is such a part of the heat that is capable of heating a liter of liquid by one degree. This is the smallest unit of energy. In our case, it has special significance. This is the amount of energy that is usually released as heat during food processing. The number of calories produced (or kilocalories) is individual for each individual product. As for drinks. For example, a gram of fat gives 9 calories, a gram of carbohydrates (or proteins) - 4 calories, and a gram of alcohol on average contains 7 calories.

By the way of life or profession, people's need for energy, which is released during food processing, is individual. One person needs a lot of food calories to cope with heavy loads, mental or physical, and for another, such a dose will be more likely to be harmful, since excess calories can "turn" into a new layer of fat on the body. And every new centimeter of cubic fat is the whole meter of the finest vessels, capillaries, with which it will be provided with everything necessary. And this, in turn, is an extra burden on the body.

So, the energy consumption depends on the kind of activity. For every hour spent by a person in a dream, "burns" about 65 calories. As mentioned above, you should not consume more food than is necessary for normal functioning, as this leads to excess weight. In other words, to the accumulation of adipose tissue. What it is necessary to do so that the body weight does not grow, but decrease? That is how to lose weight, lose weight?

You need to calculate how many calories you consume and how much you consume. Is there a difference between these two indicators, and is it significant? Do you eat more than you need or, on the contrary, do you lack the energy that it gives?

On average, to use your weight, a man needs to consume 1500 calories a day, and a woman - 1300. And you can also systematize your diet. How? For example, for breakfast you will consume three hundred calories, for lunch - as much, and for dinner - six hundred. And all of them will be 1500.

Here you may have a question: how is the energy value of the food you eat calculated? There is a special table, in which the exhaustive information is provided on this topic. In it, opposite each product, the amount of calories produced when it is processed in the intestine is determined. Such a table is not difficult to find on the Internet. With it, you can determine how many calories you consume per day. The table indicates usually how many proteins, fats and carbohydrates are in a particular product. Even if it does not indicate the energy value, then, knowing the number of calories per gram of protein, fat or carbohydrates, you can easily count how many calories you consume per day. So, a few words about those products that appear daily on your desk. Perhaps the greatest energy value of butter is creamy (748 calories), melted (887) and sunflower (899). On the second place - fat, mutton or beef (897). On the third - fat (over 700 kcal). High and caloric content of walnuts due to the high content of fat in them.

However, the information in such tables can be said to be arbitrary. For example, the energy value of bread will depend on the raw materials from which it was made. That is, from which cereal flour is extracted, from which the dough for baking bread was prepared, whether the dough is fresh or not for leaven, etc. Energy value of cow's milk on the average corresponds to 58 calories, dry - 478, and condensed - about 300.
