No one doubts that poor nutrition can play a decisive role in the occurrence of cancer. Therefore, there must be a special diet that promotes the recovery of patients affected by a cancerous tumor. World-famous physician Professor Richard Doll claims that one third of cancerous tumors are provoked by malnutrition.
Cancer lesion and its therapy is a completely different situation, and a cancer patient needs a special diet. Food products should supply the body of a sick person with the vitamins, macronutrients, amino acids and proteins that he needs. Cancer diet helps keep the immune system working.
Is it possible to use non-traditional diet methods in the presence of a cancerous tumor
Food contraindications for oncological disease are very extensive. Therefore, special nutrition systems offered by alternative medicine healers can play a negative role.
Especially terrible diet for oncology, based onfasting, or one in which the consumption of ordinary foods is replaced by herbal drinks or urine therapy.
It is impossible to stop the process of tumor growth with the help of starvation. Malnutrition will lead to a sharp deterioration in he alth. Nutrition for oncology should be complete and of high quality.
You should also avoid systems based on selective consumption of products. Such advice will do no good.
Protein-restricted diets are harmful, as this is fraught with the development of amino acid deficiencies. This approach will in no way 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. Such patients often have a reduced absorption of the elements necessary for life.
Beriberi cannot be attributed to a specific symptom of cancer. Even with complete exhaustion of the body, patients with cancer will not experience such manifestations as pellagra or scurvy.
The widely popular idea of treating cancer through vitamin therapy has not received scientific confirmation.
It should be noted that during radiation therapy it is recommended to reduce the consumption of fruits and vegetables. They do provide benefits, but high doses of the vitamins they contain can reduce the effectiveness of anticancer treatments.
Vitamin E should be taken with great care as it belongs to the groupantioxidants.
It can be said that in the treatment of cancer patients, nutrition should be supplemented only with those vitamins that the body lacks.
Mineral requirement
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 cancer treatment involves many components, therefore, it is necessary to control the content of minerals in the body.
For puffiness, doctors recommend cutting down on the sodium found in table s alt and replacing it with potassium. If the food seems bland to the patient, it is recommended to introduce pickled foods into the diet. However, this approach does not apply to all forms of cancer.
If a patient has vomiting and diarrhea after chemotherapy, sodium intake should be increased.
This proves once again that there are many different approaches to diet selection. Each case requires a specific diet.
Proper fluid intake for cancer
In the vast majority of cases, patients are not recommended to reduce their usual level of fluid intake. If the patient has swelling or the presence of parallel diseases of the genitourinary system, then the fluid intake should even be increased by introducing fermented milk products. During chemotherapy, fluid intake is doubled.
Breast Cancer Diet
Properly selected diet for oncologyhelps prevent secondary complications such as cancer recurrence, diabetes, obesity and hypertension.
Lack of excess weight to a greater extent stops the recurrence of the disease and improves the quality of life of a woman. Because patients undergoing radiation or chemotherapy tend to gain weight, it is recommended to refrain from increasing the amount of food until the end of therapy.
If you are overweight, it is recommended to gradually reduce it. It has been proven that with a decrease in body weight by 5-20% within 2 years, the risk of developing secondary diseases decreases, insulin, cholesterol, and parameters associated with the development of cancer remain normal.
General recommendations
Diet for breast cancer requires the following rules:
- Calorie content of food corresponds to body weight. The more weight, the fewer calories consumed.
- Fruits and vegetables are preferred.
- Whole flour products are used.
- Reduce fat intake.
- Limited intake of soybeans.
- To keep bones in good condition, the inclusion of 2-2.1 g of calcium per day is recommended. You also need to keep an eye on your vitamin D content and bone density levels.
- Alcoholic drinks are not consumed.
- The consumption of semi-finished products is reduced.
- Foods such as sugar, canned and red meat are limited.
ConsumptionOmega-3 and Omega-6
Diet for oncology involves the use of Omega-3 and Omega-6. Among the foods that are rich in these acids, fatty fish (mackerel, salmon, halibut, etc.) should be noted. In addition, omega-3s are found in walnuts, flaxseeds and cereals.
Omega-6 is also needed for the full functioning of the body. The substance is found in sunflower and corn oil.
However, it should be noted that Omega-3 intake should be higher and Omega-6 should be reduced.
The benefits of exposure to Omega-3s have not been scientifically proven. On the other hand, many doctors note that the substance helps to reduce triglycerides in the blood and acts as a preventive measure for the development of heart disease. Therefore, it is recommended to consume oily fish at least once a week. This recommendation does not apply to patients using anti-clotting drugs.
Flax seed consumption
Diet (breast cancer requires a certain diet) includes the consumption of flax seeds. Scientists have not established the extent to which flax seeds help reduce the development of a cancerous tumor. According to the American Research Association, their consumption does not pose any 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 the oil based on them. The amount of seeds consumed should not exceed 30 grams per day.
Increased use can provokediarrhea and disrupt the absorption of beneficial elements and medicines by the intestines. In addition, they inhibit the action of drugs such as Coumadin or Aspirin.
Diet after gastrectomy
After the surgical removal of a significant part of the stomach, a certain diet is required to restore the function of the gastrointestinal tract. During this period, it is difficult for patients to consume food in the usual way. Therefore, they resort to injections containing proteins and amino acids.
Based on blood tests, the body's need for a number of nutrients is determined.
What is the diet after gastrectomy? The recommendations are varied. After resection of the stomach, fasting for two days is recommended. On the third day, the patient can drink rosehip juice, weakly brewed tea, unsweetened compote without fruits and berries 5-6 times a day in a volume of 20-30 ml. In case of congestion in the stomach, drinking is prohibited.
It is acceptable to use baby protein food. It is administered by tube at a dose of 30-40 mg 2-3 days after surgery.
The diet is based on a gradual load on the stomach and intestines, as well as the inclusion of an increased amount of protein.
On the fourth day, the patient is allowed to eat soups, mashed fish or cottage cheese, as well as soft-boiled eggs.
On the fifth day, pureed cereals, steamed omelets and mashed vegetables in a small amount are included. With each subsequent day, the portion increases by 50 ml. On the seventh day it is 250 ml, and ontenth - 400 ml.
Thus, in the early period, the patient receives a sufficient amount of protein in an easily digestible form.
Diet 2 weeks after surgery
