Diet in Oncology: oncologist's advice

No one doubts that irrational nutrition can play a decisive role in the onset of cancer. Therefore, there must be a special diet that helps to restore patients affected by a cancerous tumor. The world famous physician Professor Richard Doll claims that one third of cancerous tumors are caused by malnutrition.

Cancer and its therapy are a completely different situation, and the cancer patient needs a special diet. Food products must supply the body of a sick person with vitamins, macronutrients, amino acids and proteins that are necessary to him. Diet with oncology helps to maintain the immune system.

Is it possible to use non-traditional diet methods in the presence of a cancerous tumor

Food contraindications for cancer are very extensive. Therefore, special feeding systems offered by doctors of alternative medicine can play a negative role.

In particular, a terrible diet for oncology, based on starvation, or the one in which the consumption of ordinary products is replaced by drinks based on herbs or urine therapy.

It is impossible to stop the process of tumor growth with starvation. Malnutrition will lead to a sharp deterioration in health. Nutrition with oncology should be high-grade and high-quality.

Also, it is necessary to avoid systems based on selective consumption of products. Such advice will not bring anything good.

Harmful diets with a restriction of protein intake, as it is fraught with the development of a deficiency of amino acids. This approach does not help fight the tumor, but, on the contrary, will accelerate its growth.

The Importance of Vitamin Therapy

Diet after removal of oncology involves the use of vitamins. They play a huge role in the treatment of cancer patients. In such patients, there is often a decreased absorption of elements necessary for life.

You can not treat avitaminosis to a specific symptom of cancer. Even with complete exhaustion of the body in patients with cancer, there will be no manifestations such as pellagra or scurvy.

The popular idea of cancer treatment through vitamin therapy has not been scientifically confirmed.

It should be noted that when radiotherapy is recommended to reduce the consumption of fruits and vegetables. They do benefit, but high doses of vitamins contained in them can reduce the effectiveness of antitumor treatment.

With great caution should be taken vitamin E, because it belongs to the group of antioxidants.

We can say that in the treatment of cancer patients, nutrition should be supplemented only with those vitamins that the body lacks.

The need for minerals

The question of the use of minerals is also very important in oncology. Fruits, vegetables, meat products and fish are rich in these elements, but the treatment of cancer includes many components, so it requires monitoring of the mineral content in the body.

When swelling, doctors recommend reducing the intake of sodium contained in table salt, and replace it with potassium. If the food seems fresh to the patient, then it is recommended to include pickled products in the diet. However, this approach is not used for all forms of cancer.

If after a chemotherapy in the patient there is vomiting and diarrhea, the intake of sodium should be increased.

This once again proves that when choosing a diet, a variety of approaches are used. In each specific case, a certain diet is required.

Proper fluid intake in the presence of cancer

In the vast majority of cases, patients are not recommended to reduce the usual level of fluid intake. If the patient has swelling or the presence of parallel diseases of the genitourinary system, then the intake of the liquid should be even increased by the introduction of fermented milk products. During the chemotherapy, the fluid intake is doubled.

Diet for breast cancer

Correctly selected diet for breast cancer helps prevent such secondary complications as the re-development of cancer, diabetes, obesity and hypertension.

Absence of excess weight largely stops the relapse of the disease and improves the quality of life of a woman. Since patients undergoing radiotherapy or chemotherapy have a tendency to increase in weight, it is recommended to refrain from increasing the amount of food until the end of therapy.

When excess weight is recommended, its gradual decrease. It has been proved that when the weight of the body decreases by 5-20% within 2 years, the risk of developing secondary diseases decreases, the values of insulin, cholesterol, and also parameters related to the development of cancer are preserved.

General recommendations

The diet for oncology of the breast involves the following rules:

  • Caloric content of food corresponds to body weight. The more weight, the less calories are consumed.
  • Preference for fruit and vegetables.
  • Products from wholemeal are consumed.
  • Reduces fat intake.
  • The intake of soy is limited.
  • To maintain bones in good condition, it is recommended to include 2-2.1 g of calcium per day. Also, you need to monitor the vitamin D content and bone density level.
  • Do not drink alcoholic beverages.
  • Reduces the use of semi-finished products.
  • Limited products such as sugar, canned and red meat.

Consumption of Omega-3 and Omega-6

Diet in oncology involves the use of Omega-3 and Omega-6. Among the products that are rich in these acids, it should be noted fatty fish (mackerel, salmon, halibut, etc.). In addition, Omega-3 is found in walnuts, flaxseeds and cereals.

Omega-6 is also needed for the full-fledged activity of the body. The substance is found in sunflower and corn oil.

However, it should be noted that consumption of Omega-3 should be higher, and Omega-6 should be reduced.

The benefits of exposure to Omega-3 have not been scientifically proven. On the other hand, many doctors note that the substance contributes to a decrease in blood triglycerides and acts as a prophylaxis of the development of heart disease. Therefore, the consumption of oily fish is recommended at least once a week. This recommendation is not applicable to patients who take medications that help reduce coagulability.

Consumption of flax seeds

Diet (oncology of the mammary glands requires a specific diet) includes consumption of flax seeds. Scientists have not established to what extent flax seeds contribute to a reduction in the development of a cancerous tumor. According to the American Research Association, their consumption poses no danger to women who have not had cancer. The same can be said about women who use "Tamoxifen" or other hormonal drugs. Moreover, the seeds themselves are preferable to oil based on them. The amount of seeds consumed should not exceed 30 g per day.

Increased use can provoke diarrhea and disrupt the absorption of useful elements and medicines in the intestine. In addition, they inhibit the action of drugs such as "Coumadin" or "Aspirin."

Ration after gastrectomy

After prompt removal of a large part of the stomach requires a certain diet to restore the function of the gastrointestinal tract. During this period, it is difficult for patients to consume food in the usual way. Therefore, injections with protein and amino acids are used.

Based on blood tests, the body's need for a number of nutrients is determined.

What is the diet after a stomach resection? Recommendations are diverse. After resection of the stomach, fasting is recommended for two days. On the third day, the patient can consume juice from the dog rose, slightly boiled tea, unsweetened compote without fruit and berries 5-6 times a day in a volume of 20-30 ml. With stagnant phenomena in the stomach, drinking is prohibited.

It is acceptable to use baby protein nutrition. It is injected with a probe in a dose of 30-40 mg 2-3 days after the operation.

The diet is based on a phased load on the stomach and intestines, as well as the inclusion of increased amounts of protein.

On the fourth day, the patient is allowed to use soups, puree from fish or cottage cheese, as well as eggs boiled soft-boiled.

On the fifth day included mashed porridge, omelettes for steaming and puree from vegetables in small quantities. With each subsequent day, the portion is increased by 50 ml. On the seventh day, it is 250 ml, and on the tenth - 400 ml.

Thus, in the early period, the patient receives a sufficient amount of protein in a readily digestible form.

Diet 2 weeks after surgery

Diet after gastrectomy (oncology) involves the consumption of certain foods two weeks after surgery. This diet is held for 4 months.

If the patient has complications such as gastritis, peptic ulcer or anastomosis, then he should stick to this diet for longer.

The main goal in the formulation of a diet is to stop the inflammatory process and prevent dumping syndrome.

Patients are recommended to eat meat and fish with a high level of protein, as well as the optimal amount of complex carbohydrates contained in cereals, vegetables, cereals and unsweetened fruits.

At the same time, you should limit the intake of easily digestible carbohydrates (sugar, flour products, fruit drinks, juices, fried foods).
