Diet: diet and nutrition for a healthy and sick person

The diet should be adapted to the metabolic processes disturbed in conditions of illness, and should include sparing of the damaged organ and disrupted functions. For this purpose, certain food products that have undergone special technological processing are selected.
The most widely used diets are those used for diseases such as peptic ulcers, colitis, obesity, etc. Each diet has several options, used sequentially depending on the stage and phase of the disease. Taking into account individual indications, as a rule, in a hospital setting fasting days can be prescribed for a short time (1-2 days).
The principles of construction are different; the most widespread are fasting days, the names of which correspond to the product consumed on that day (meat, fish, vegetables, fruit, etc.).

Diets for diseases
The diet for gastric and duodenal ulcers has several options depending on the stage of the disease. In the initial stages, diet No. 1 is used, which provides for a gentle diet. During the period of exacerbation of the disease, diet No. 1a is prescribed, which excludes foods that promote the secretion of gastric juice. In convalescence they switch to diet No. 16, which provides for a gradual expansion of the diet.
A diet for colitis is aimed at reducing the load on the intestines and involves excluding from the diet foods that cause fermentation and gas formation. In case of obesity, a diet is prescribed with a restriction of fats and carbohydrates, as well as an increase in the consumption of proteins and fiber.
Fasting days
Fasting days are days when the body's nutrition is limited to certain foods, for example, meat, fish, vegetables or fruits. Such days help the body get rid of toxins and waste, and also speed up metabolism. However, doing fasting days on your own can be dangerous to your health, so you should consult your doctor before starting.
