General characteristics of nutrition and its purpose


Gout is a common disease of the body, which is based on a violation of protein metabolism, which leads to an increase in the content of uric acid in the blood and urine and the deposition of uric acid salts in the joints. Often patients suffer from polyarthritis, obesity.
Urine is a saturated concentrated solution of salts of various salts (urinary, phosphoric, oxalic). A healthy person does not precipitate salt. This is hampered by the presence of so-called protective colloids, which increase the solubility of urine. When the number of colloids decreases because of a disturbance in the work of the kidneys, the salts begin to precipitate and are deposited in the tissues of the body and joints. Thus, the beginning of the formation of the deposition of salts, stones can be considered a violation of colloidal equilibrium.
To the deposition of salts predisposes and a sharp fluctuation in the reaction of urine. Normally, it is weakly acidic. If the reaction becomes acidic, salts of uric acid can be deposited and stones are formed. With an alkaline reaction of urine due to an excess of salts of phosphoric acid, stones of a different kind can be formed-phosphates.
To a lesser extent from the shifts in the urine reaction, the appearance of stones, which include oxalate salts - oxalates, depends.
One of the most important causes of changes in urine is considered a metabolic disorder in the body, especially water - salt, in the regulation of which the kidneys participate.
Uric acid and its salts are the final product of purine metabolism. It has been proved that with the abundant intake of purines with food, the formation of uric acid rises, its content in the blood increases and urinary excretion increases. Consumption of food rich in purines, during the day increases the uric acid reserves in the body twice or more. It is noted that the highest incidence rate among those who in large quantities consume meat products, beer, grape wines.
The purpose of therapeutic nutrition: to promote the normalization of the exchange of purines, reduce the formation of uric acid in the body and its salts, shift the urine reaction to the alkaline side.

General characteristics of nutrition and its purpose

  1. General characteristics of nutrition and its purpose
    In a complex set of therapeutic measures used in cirrhosis of the liver, not the last place belongs to proper nutrition. When constructing a scheme of therapeutic nutrition, the degree of impairment of one or another function of the liver is taken into account. The diet does not differentiate depending on the form of cirrhosis, but differs depending on the severity of the disease. If there are signs of hepatic
  2. General characteristics of nutrition and its purpose
    Irritants, which cause a bronchial-asthmatic attack, are mainly foreign proteins that re-enter the body. Their nature is different: in some cases they are of bacterial origin, in others they are food, and organic particles that are in the air (particles of clothing, plants, leather, shoes, etc.) also matter. In bronchial asthma, no indication of
  3. General characteristics of nutrition and its purpose
    Nutrition for pneumonia (acute inflammation of the lungs) plays an important role in the treatment of this disease. It depends on the general condition of the patient and the stage of the illness (the height of the illness, the period of recovery). With bed rest and high temperature, the food should be gentle for the organs of the cardiovascular, digestive systems and for the kidneys. The main goal is to maintain the common forces of the body, increase
  4. General characteristics of food
    1. The exclusion of products containing many purines, oxalic acid. 2. Moderate salt restriction, increase in the number of alkalizing products (dairy, vegetables, fruits). 3. Increase in the amount of free fluid (in the absence of contraindications from the cardiovascular system). 4. Decrease in nutrition of proteins and fats, and with concomitant obesity - and carbohydrates. From the diet
  5. General characteristics of the diet
    In the diet, the content of animal fat and digestible carbohydrates is reduced. Proteins correspond to the physiological norm. The degree of reduction of fats and carbohydrates depends on the body weight. Limited table salt, free liquid, cholesterol, extractives. Increased content of vitamins C and Group B, dietary fiber, potassium, magnesium, trace elements (vegetable oils, vegetables, fruits, cottage cheese,
  6. The main goals and objectives of the sanitary and epidemiological survey of public catering establishments
    The EPP survey is an important part of the work of the State Sanitary and Epidemiological Surveillance and other monitoring organizations. The main purpose of the survey is to identify potential sanitary and epidemiological disturbances that can adversely affect the quality of products and the health of consumers and staff. The main tasks of the sanitary-epidemiological
  7. general characteristics
    Allergic reactions can occur in the treatment of drugs, household and industrial chemicals, as well as certain foods (food allergies). Under these conditions, the food should be physically complete, but not excessive. In the diet restrict carbohydrates, especially quickly absorbed (sugar, honey, jam, chocolate, sweet drinks). With decreasing quantity
  8. General characteristics of the principles of education
    Giving a characterization of this or that principle of upbringing, it is important to take into account that each idea embedded in it is a reflection of one or several regularities. Their essence is revealed and implemented in practice in the form of requirements and pedagogical rules of educational activity. The principles of education, as it were, allow us to transfer the bridge from pedagogical theory to practical activity. Their

    Acute respiratory insufficiency (ODN) is considered as a condition of the body in which the normal gas composition of the blood (paO2 - 92-100 mm Hg, paCO2 = 35-45 mm Hg) is provided (or not provided) by such a voltage of the compensatory mechanisms , which significantly affects the patient's condition. Proceeding from this definition, the notion of compensated and

    The genus Clostridium includes more than 100 species. This genus combines pathogenic and saprophytic anaerobic spore-forming rod-shaped microorganisms, with the exception of several sulfate-reducing pigment-forming species. The generic name is given on the basis of the similarity of these microorganisms with the spindle (closter - lat., Small spindle), which they acquire as a result of bloating bacterial
