Real energy costs for food


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

The whole process of digestion, from start to finish, consumes a huge amount of energy. It is expended on the production of saliva and enzymes (during the purification program your body will increase the enzyme content by consuming large quantities of raw foods, which will save energy and maintain the digestive process). Muscles need energy to cut and push food into the stomach, which must produce digestive juices and serve the digested food in the intestines. The pancreas and the gallbladder produce substances necessary for digestion, insulin and glucagon, respectively.
When food breaks down into small enough molecules, they are absorbed by the walls of the intestine and enter the bloodstream, after which these building blocks are transported 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 its reception.
The more you eat, the longer the process of food processing lasts, and the later the signal on the onset of detoxification
As in modern life during the day we eat repeatedly, the need for energy is permanent. Often, nothing else is just missing. Let's remember the traditional Thanksgiving dinner: the only possible activity after all this culinary abundance is a nap.
Although each has its own theory explaining such a dramatic drop in the energy level - from the drowsiness-causing tryptophan contained in turkey meat to an increase in the alkali content in the blood as a result of the production of excessive amounts of acids in the stomach - the fact remains: any plentiful feast entails desire to sleep, since digestion of food consumes a lot of energy. This is characteristic of animals of all kinds. After a successful hunt and the subsequent feast, the lions sleep for a few days.

Real energy costs for food

  1. Energy costs of the organism
    Energy costs of the human body are made up of the expenditure of energy on the main exchange, the expenditure of energy on the specifically dynamical action of food and energy expended on the performance of physical and mental work. The energy expenditure on basic metabolism and the specifically dynamic effect of food can not be regulated by the will of man and therefore it is customary to refer to unregulated energy expenditure. Expenses
  2. Methods for studying the energy expenditure of an organism
    To determine the energy expenditure of the body use the method of direct and indirect calorimetry and calculation method. The method of direct calorimetry is based on the measurement of heat, which emits the body at any energy consumption. For this purpose, a calorimetric chamber is used where the person is placed. By the difference in water temperatures in the incoming and outgoing pipes in the chamber, the amount of heat is measured,
  3. The concept of hygienically nutrition. Nutrition standards Food products, their composition and energy value.
    Nutrition is a complex process of ingestion, digestion, absorption and absorption in the body of nutrients necessary to cover its energy expenditure, the construction and renewal of cells and tissues of the body, the regulation of the physiological functions of the body. In hygiene, the term "nutrition" is used, meaning a diet built on scientific principles that can fully meet the need for
  4. Energy basis of separate food
    One of the most important arguments in favor of separate nutrition is the concept of "living" energy, developed in the second half of the XIX century by the Swiss Max Bircher-Banner, according to which the biological value of products is determined not by their caloric value, but primarily by the ability to increase the vital force in the body. In this case, preference should be given to the plant

  6. Hygienic requirements for places of carrying out of hardening procedures. Prevention and first aid for heat stroke, sunburn, hypothermia, drowning. Nutrition for 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 high physical and neuropsychic stress accompanied by a significant activation of all metabolic processes, his body's need for energy and for certain nutrients increases. Therefore, in the exercise of physical culture and sports, the food must: fully reimburse the expenses spent by the athlete
  7. Determination of costs for carrying out veterinary measures to eliminate the disease under study.
    Payment of veterinary specialists; Zar. Fee: Vet. Wed. -1500 rub. vet. Feld. - 700 rubles. Hourly rate: Vet. Wed. - 1500: 166 = 9.03 rubles. vet. Feld. - 700: 166 = 4.2 rubles. At the events total spent - 24.6 hours., Total on the charge. the payment went: vet. Wed. - 9.03 * 24.6 = 222.14 rubles.
  8. Basis for assessing the cost-effectiveness of medical services
    ... It is unrealistic to expect and expect that with the expansion of research, the increase in allocations for health care, the increase in the number of doctors, nurses, hospitals and drugs, the incidence will decrease, and the cost of medical care and expenses will diminish over time. John Fry The Current Situation in Public Health in Russia is characterized by an ever-growing need
  9. Energy balance
    The basis for measuring the energy consumed by the human body and the energy of the food consumed is one and the same unit of measurement - joule or calorie. This made it possible to solve an important task of establishing the conformity of human nutrition to the energy costs it produces. Nutrition, in which the caloricity of the daily diet does not cover the energy costs produced during the day,
  10. RETAILS ON DEMOGRAPHIC AND GENDER THREATS AND REAL PRACTICE
    "Fundamentals of the social concept," like other general church documents, only a declaration of certain principles that were not really discussed, and therefore not perceived by the Church as a social institution. It is difficult to say whether the deans read them in the diocesan administrations, not to mention the parish priests, but, at least, refer to them in the diocesan and parish press not often.
  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 DIAGNOSIS OF COGNITIVE PROCESSES Express diagnostics is a set of seven tasks for children of three to seven years. Using the game material and special psychological
  12. Prerequisites for Economic Estimates of Cost-Effectiveness in Providing Medical Care to the Population
    The decision-making strategy in the healthcare system of Russia must obey the principle: "Achieving maximum efficiency from each unit of forces and resources invested in the healthcare sphere" is the only realistic way in the conditions of reforms. It should be noted that many of the leaders of the health facility express their desire to be guided by this principle, who have become accustomed over many years of work to the fact that all
  13. Energy and plastic meaning of food
    Food is the main source of energy for humans. It is a certain combination of food products of animal and vegetable origin. The food contains: 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 nutrition, the body first of all receives the energy necessary for life processes, then the integral quantitative measure for evaluating the consumed food is its energy value, or caloric value. As you know, energy costs are made up of the costs of basic metabolism, specifically the dynamic action of nutrients and muscle work. Energy value
  15. Nutrition as a factor in maintaining and promoting health. Physiological norms of nutrition. The importance of individual components of food in human nutrition. The importance of proteins in human nutrition, their norms and sources of intake into the body
    Nutrition is one of the most active and important factors of the external environment, which exerts a diverse influence on the human body, ensures its growth, development, preservation of health, work capacity and optimal longevity. All this is provided by a daily, regulated meal with a certain set of foods. Food products are complex
  16. Energy density
    In infants and young children, energy consumption per kilogram of body weight is 2-3 times greater than in adults (Figures 11 and 12). Because 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 deficit and, consequently, to
  17. Modern cognitive norms of military psychological research: possible and realistic standards
    The above generalizations and provisions objectively raise the issue of the allocation of methodological foundations - standards for the construction of modern military psychological research. In other words, it is necessary to present a system of cognitive norms, on which it is oriented and on which it is organized. Such a set of norms, in the first approximation, can be represented in the form of a pyramid of cognitive
  18. ENERGY BALANCE
    The energy balance is determined by the energy received and expended. If the energy received by the patient is equal to the spent energy, they say about the zero balance. A negative balance arises if the energy expended is greater than the received energy. A positive energy balance is achieved if the energy received is greater than the spent energy. In this case, excess energy is deposited as fat and
  19. Energy evaluation of food ration
    Since in the process of feeding the body, first of all, receives the energy necessary for life processes, then the integral quantitative measure for assessing the food consumed is its energy value, or caloric value. As you know, energy costs are made up of the costs of basic metabolism, specifically the dynamic action of nutrients and muscle work. For an adult
  20. Redistribution of energy flows
    Sometimes, at the same time, there are so many requests for energy supply that it is necessary to make an adjustment in the energy budget within a fraction of a second. The body temporarily suspends the performance of certain functions, inhibits others and enables the third to fully utilize the energy "cash flows", since these functions are most important. Neurons of the brain have higher
