Abstract
The article provides a brief overview of the issues of nutritional therapy in the rehabilitation of cancer patients. Excess sugar in food and drink, fatty and high-calorie foods, processed meat, trans fatty acids, preservatives and dyes are risk factors for the formation of malignant tumors. Patients should be informed about adherence to a healthy lifestyle and exclusion from the diet of foods containing carcinogens to reduce the recurrence of the disease. Chemotherapy courses and radiation sessions are accompanied by a number of side effects that lead to a decrease in the body's defense systems. For the recovery of cancer patients, protein, vitamins and minerals must be present in the diet. All nutrients are better obtained from the natural foods. To maintain a healthy diet, the World Cancer Research Foundation (WCRF) and the American Institute for Cancer Research (AICR) recommends you toinclude vegetables, fruits, whole grains and legumes in your daily diet. The article focuses on mare's milk, its multicomponent composition, which has immunomodulatory, antiviral, antibacterial properties. To increase the effectiveness of rehabilitation measures in patients after antitumor treatment, it is advisable to include mare's milk in medical nutrition, which has therapeutic and health-improving properties, and it is also possible to use it in patients undergoing antitumor cytostatic therapy. Further comprehensive study of the therapeutic and rehabilitation potential of mare's milk would make it possible to use this product more widely as an important component of nutritional support for cancer patients during specific therapy courses, which will have a positive effect on their survival rates and quality of life. In the treatment of malignant tumors, the main emphasis is on the development of strategies, new treatment options, and medical nutrition and a healthy lifestyle are an integral part of their complex rehabilitation.
