The real energy cost of food


Food-related processes consume a significant portion of daily energy expenditure. Digestion, absorption, transportation of nutrients in the bloodstream and their absorption by the cells are all very expensive processes for the body, not to mention growing, collecting and processing agricultural products, as well as making money to purchase it. Sometimes we spend more energy on food processing than we receive as a result of its absorption.
The transformation of food into fuel and building blocks for tissues is one of the most energy-intensive functions of the body.
Any abundant feast entails the desire to sleep, as the digestion of food consumes a lot of energy

The whole digestion process, from start to finish, consumes a tremendous amount of energy. It is spent on the production of saliva and enzymes (during the purification program in your body, the content of enzymes will increase due to the consumption of large quantities of raw foods, thereby saving energy and maintaining the digestive process). Muscles need energy to reduce and push food into the stomach, which must produce digestive juices and supply digested food to the intestines. The pancreas and gallbladder produce substances necessary for the absorption of food - insulin and glucagon, respectively.
When food breaks down into fairly small molecules, they are absorbed by the intestinal walls and enter the bloodstream, after which these building blocks are transferred to different parts of the body, where they are absorbed by the cells and used to form tissues, carry out chemical reactions and for other purposes.
As a result, the process of digestion requires huge energy costs.
The process of food processing is completed approximately 8 hours after it is taken.
The more you eat, the longer the process of processing food lasts and the later the signal to start detoxification is activated
Since in the conditions of modern life during the day we eat many times, the need for energy is permanent. Often, nothing else is enough for her. Recall the traditional Thanksgiving dinner: the only possible activity after all this culinary abundance is nap.
Although each has its own theory explaining such a drastic decrease in energy levels, from drowsiness-causing tryptophan contained in turkey meat to an increase in blood alkali as a result of an excessive amount of acid in the stomach, it’s a fact: any rich feast entails the desire to sleep, as the digestion of food consumes a lot of energy. This is characteristic of animals of all kinds. After a successful hunt and subsequent feast, the lions sleep for several days.

The real energy cost of food

  1. Energy costs of the body
    The energy consumption of the human body is composed of the expenditure of energy on the basic metabolism, the expenditure of energy on the specifically dynamic action of food and the energy expended on performing physical and mental work. The energy consumption for basal metabolism and the specifically dynamic action of food cannot be regulated by the will of man and therefore it is customary to attribute it to unregulated waste of energy. Expenses
  2. Methods for studying the body's energy costs
    To determine the energy expenditure of the organism, the method of direct and indirect calorimetry and the calculation method are used. The method of direct calorimetry is based on the measurement of heat, which the body emits at any energy consumption. For this purpose a calorimetric chamber is used, where a person is placed. The difference in water temperature in the incoming and outgoing pipes in the chamber measure the amount of heat,
  3. The concept of hygienic nutrition. Nutrition norms Food products, their composition and energy value.
    Nutrition is a complex process of receipt, digestion, absorption and assimilation in the body of nutrients necessary to cover its energy expenditure, build and renew cells and tissues of the body, and regulate the physiological functions of the body. In hygiene, the term “good nutrition” is adopted, which means a food built on a scientific basis that can fully meet the need for
  4. Energy basis of separate power
    One of the most important arguments in favor of separate nutrition is the concept of "living" energy, developed in the second half of the 19th century by the Swiss Max Bircher-Benner, according to which the biological value of products is determined not by their caloric value, but primarily by the ability to increase the charge of vitality in the body. In this case, plant preference should be given.

  6. Hygienic requirements for tempering places. Prevention and first aid for heat stroke, sunburn, hypothermia, drowning. Nutrition of athletes of various specializations, taking into account the energy and plastic needs of the body.
    During training sessions and especially competitions, when an athlete experiences a high physical and neuropsychic stress, accompanied by a significant activation of all metabolic processes, his body's need for energy and certain nutrients increases. Therefore, when doing physical exercises and sports nutrition should: fully reimburse the athlete consumed
  7. Determination of the cost of carrying out veterinary measures to eliminate the disease under study.
    Remuneration of veterinary specialists; Zar Fee: slow. vr. –1500 rub. wet feld - 700 rubles. Hourly rate: slow. vr. - 1500: 166 = 9.03 rubles. wet feld - 700: 166 = 4.2 rubles. At the event just spent - 24.6 hours, total for zar. payment went: slow. vr. - 9.03 * 24.6 = 222.14 rubles.
  8. Fundamentals of cost effectiveness in the production of medical services
    ... It is unrealistic to hope and expect that with the expansion of research, increasing allocations for health care, increasing the number of doctors, nurses, hospitals and drugs, the incidence will decrease, and the cost of medical care and expenses for it will decrease with time John Fry characterized by ever-pressing need
  9. Energy balance
    The basis for measuring the energy consumed by the human body and the energy of food consumed is one and the same unit of measurement - joule or calorie. This made it possible to solve the important problem of determining the conformity of human nutrition to the energy costs that it produces. Nutrition, in which the caloric content of the daily diet does not cover the energy expenditures made during the day,
  10. RETAIL ON THE DEMOGRAPHIC AND GENDER THEMES AND REAL PRACTICE
    The “Fundamentals of the Social Concept”, like other church-wide documents, is only a declaration of certain principles that were not really discussed, and therefore were not perceived by the Church as a social institution. It is difficult to say whether they were read in the diocesan departments by the dean, not to mention parish priests, but, in any case, they are not often referred to in the diocesan and parish press.
  11. Diagnosis of the real psychological capabilities of the child
    Diagnosis of the child’s real psychological capabilities consists of diagnosing cognitive processes and diagnosing emotional disorders. The following diagnostic methods are used. EXPRESS DIAGNOSTICS OF INFORMATIVE PROCESSES Express diagnostics is a set of seven tasks for children of three to seven years old. Using game material and special psychological
  12. Prerequisites for economic estimates of cost-effectiveness in the provision of medical care to the population
    The strategy of decision-making in healthcare in Russia should be subordinated to the principle: “Achieving maximum efficiency from each unit of forces and funds invested in the healthcare sector” is the only real way in the context of reforms. It should be noted that not many of the managers of medical and preventive treatment institutions, who have been accustomed to
  13. Energy and plastic value of food
    Food - the main source of energy for humans. It is a combination of food of animal and vegetable origin. Foods contain: 1. Proteins - plastic value 2. Fats - energy value 3. Carbohydrates - energy value 4. Vitamins - regulatory and catalytic value 5. Microelements and mineral salts -
  14. Energy assessment of the diet.
    Since, in the process of feeding, the organism first of all receives the energy necessary for life processes, the integral quantitative measure for the assessment of food consumed is its energy value, or caloric value. As you know, energy costs are the sum of the costs of basal metabolism, specifically the dynamic effect of nutrients and muscle work. The energy value
  15. Nutrition as a factor in the preservation and promotion of health. Physiological norms of nutrition. The value of the individual components of food in human nutrition. The value of proteins in human nutrition, their norms and sources of entry into the body
    Nutrition is one of the most active and important environmental factors, which has a variety of effects on the human body, ensures its growth, development, preservation of health, disability and optimal longevity. All this is provided by a daily, regulated meal with a certain set of foods. Foods are complex
  16. Energy density
    In infants and young children, energy consumption per kilogram of body weight is 2-3 times more than in adults (Fig. 11 and 12). Since they have to absorb large amounts of energy, the key determinant of energy consumption is the energy density of food for complementary foods. Too low energy density can lead to energy shortages and, therefore, to
  17. Modern cognitive norms of military-psychological research: possible and real standards
    The generalizations and provisions outlined above objectively raise the question of identifying the methodological foundations - the standards for constructing a modern military-psychological research. In other words, it is necessary to present the system of cognitive norms, by which it is oriented and according to which it is organized. Such a set of norms, as a first approximation, can be represented as a pyramid of cognitive
  18. ENERGY BALANCE
    The energy balance is determined by the received and expended energy. If the energy received by the patient is equal to the expended energy, they speak of a zero balance. Negative balance occurs when the expended energy is greater than that received. A positive energy balance is achieved if the received energy is more expended. In this case, excess energy is deposited as fat and
  19. Energy Diet Assessment
    Since, in the process of feeding, the organism first of all receives the energy necessary for life processes, an integral quantitative measure for evaluating the food consumed is its energy value, or caloric value. As you know, energy costs are the sum of the costs of basal metabolism, specifically the dynamic effect of nutrients and muscle work. For an adult
  20. Redistribution of energy flows
    Sometimes at the same time there are so many applications for the provision of energy that it is necessary to make adjustments in the energy budget within a fraction of a second. The body temporarily suspends the performance of some functions, inhibits others, and gives the third a chance to fully use energy “cash flows”, since these functions are most important. Brain neurons are superior
