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 salts in the joints. Often, patients suffer at the same time polyarthritis, obesity.
Urine is a saturated concentrated solution of salts of various salts (urinary, phosphoric, oxalic). In a healthy person, salt does not precipitate. This is hampered by the presence of so-called protective colloids, which increase the dissolving ability of urine. When the amount of colloids decreases due to the impaired functioning of the kidneys, salts begin to precipitate and are deposited in body tissues and joints. Thus, the beginning of the formation of deposits of salts, stones can be considered a violation of the colloidal equilibrium.
To the deposition of salts predisposes a sharp fluctuation of the reaction of urine. Normally it is slightly acid. If the reaction becomes too acidic, uric acid salts can be deposited and stone stones form. When alkaline urine due to an excess of salts of phosphoric acid can form stones of another kind - phosphates.
To a lesser degree, the appearance of stones, which include oxalate salts of oxalic acid, depends on the changes in the urine reaction.
One of the most important causes of changes in the urine is a metabolic disorder in the body, especially water - salt, in the regulation of which the kidneys are involved.
Uric acid and its salts are the end product of purine metabolism. It is proved that with the abundant supply of purines with food, the formation of uric acid increases, its content in the blood increases and the excretion with urine increases. Consumption of food rich in purines during the day increases the reserves of uric acid in the body twice or more. It has been observed that the highest incidence rate among those who consume large quantities of meat products, beer, and grape wines.
The goal of therapeutic nutrition is to help normalize the exchange of purines, reduce the formation of uric acid in the body and its salts, and 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 interventions used in cirrhosis of the liver, far from the last place belongs to proper nutrition. When constructing a scheme of therapeutic nutrition, the degree of impairment of a particular liver function 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 signs of hepatic occur
  2. General characteristics of nutrition and its purpose
    Stimuli that cause an asthma attack are mostly foreign proteins re-entering the body. Their nature is different: in some cases they are of bacterial origin, in others - food, organic particles that are in the air (particles of clothing, plants, leather, shoes, etc.) are also important. In case of bronchial asthma without indications
  3. General characteristics of nutrition and its purpose
    Nutrition for pneumonia (acute pneumonia) plays an important role in the treatment of this disease. It depends on the general condition of the patient and the stage of the disease (the height of the disease, the recovery period). With bed rest and high temperature nutrition should be sparing for the organs of the cardiovascular, digestive systems and for the work of the kidneys. The main goal is to maintain the overall strength of the body, increase
  4. General power characteristic
    1. Exclusion of products containing a lot of purines, oxalic acid. 2. Moderate salt restriction, increase in the number of alkalizing foods (dairy, vegetables, fruits). 3. Increasing the amount of free fluid (in the absence of contraindications from the side of the cardiovascular system). 4. Reduction in the diet 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 easily digestible carbohydrates is reduced. Proteins meet the physiological norm. The degree of reduction of fats and carbohydrates depends on body weight. Limited salt, free liquid, cholesterol, extractives. The content of vitamins C and B group, dietary fiber, potassium, magnesium, trace elements (vegetable oils, vegetables, fruits, cottage cheese,
  6. The main goals and objectives of the sanitary-epidemiological survey of public catering enterprises
    The PEP survey is an important part of the work of the State Sanitary and Epidemiological Surveillance and other regulatory organizations.
