What does a nutritionist do?
The nutritionist is engaged in the right choice of diet, both for healthy and sick people. For a healthy person, a dietician will help to make the right diet, which will supply his body with the necessary amount of nutrients, vitamins, minerals and trace elements.
At the same time, a nutritionist will help you to choose the right calorie intake. Nowadays, people eat a lot of "empty" food. This food is very rich in carbohydrates, fats and proteins, that is, it is very caloric. However, such foods can be poor in vitamins and other beneficial substances.
With such nutrition, adults and even children easily gain excess weight, but their body is starving and lacks vital substances. Such a "hunger strike" inhibits the growth of bones, cartilage, muscle tissue, nerve cells and other important parts and systems of the body.
With a lack of vitamins and trace elements in the diet, the body is not able to produce some of the most important hormones. For example, with iodine deficiency, the thyroid gland can not produce its hormone.
Therefore, the task of a dietician is to create a balanced diet, in which there will be not only "empty" calories, but all the substances necessary for a healthy life. Such a diet is called healthy. In some regions, in water or food, there is a pronounced deficit of some substances, for example, iodine or selenium. Then the nutritionist makes a special emphasis in the diet on the replenishment of these substances or appoints their reception in medical preparations. Such a diet is called preventive. After all, filling the deficit is an excellent prevention of the development of various diseases.
If a person is treated with a disease by a nutritionist, the task of a dietician is to make up a therapeutic diet. Such a diet not only includes useful foods, but it eliminates harmful foods or ways of preparing them.
The therapeutic diet can help the sick person to restore the correct process of metabolism in the body. In addition, there are many foods that have a curative effect for a particular disease. Their proper use in food can contribute to the fastest recovery of the body and recovery.
What diseases are treated by a nutritionist?
The competence of a dietitian includes quite a few diseases that can be treated with a diet. Again, an appeal to a dietician can help prevent the development of various diseases: from colds and diseases of the gastrointestinal tract, to cancer.
What kind of patients can be useful and even need a visit to a dietician? First, they are people with gastrointestinal diseases. Which is quite logical, because, first of all, any food gets into the gastrointestinal tract, so it is digested, absorbed into the blood and then it spreads all over the body.
Therefore, malnutrition is the primary cause of gastrointestinal diseases. And proper nutrition can in itself serve as a cure for various gastritis, colitis, cholecystitis, and so on.
At the same time, a dietician can exclude from the diet different foods, for example, fatty or spicy food. In addition, he can advise the best ways of cooking. Can exclude from the diet fried foods or fresh fruits and vegetables, replacing them with boiled and baked food, or products cooked on steam.
Another area of activity of a dietitian is the treatment of cardiovascular diseases. Malnutrition can cause abnormalities in the functioning of the heart or blockage of blood vessels. Correction of the diet will help improve heart function and avoid thrombosis and other similar diseases.
Weight loss or obesity is another disease that falls within the competence of a dietitian. Charging or proper physical activity can not produce the desired results unless supplemented with the right nutrition. Nutritionists are studying how metabolic processes occur in the human body. This knowledge can help increase the efficiency of metabolism and accelerate the reduction of excess weight.
The doctor-dietician can give consultation and at such disease, as an anorexia. Unfortunately, it is becoming "more popular" among teenage girls and young women. It's just necessary to choose a high-calorie and high-diet diet to help patients gain weight and restore health.
Another area of activity of a dietitian is viral or infectious diseases. Of course, the diet itself can not cure you of flu or cold. But it can help the body fight the virus or infection. After all, it is not a secret for anyone that some food products are especially rich in vitamins and minerals that strengthen human immunity. Strong immunity itself is able to quickly and effectively cope with most infections and viruses.
In addition, the consultation of a dietitian doctor is simply necessary for the prevention or treatment of cancer. Many foods are rich in substances that neutralize carcinogens and prevent the proliferation of cancer cells.
Health food can strengthen the body during the passage of chemotherapy and contribute to its early recovery.
