This statement has no scientific basis.

The view that patients need to deliberately limit their nutrition during anti-tumor treatment is very one-sided.

Abnormal proliferation of tumor cells can compete with normal tissues and consume nutrients from the human body. Meanwhile, anti-tumor treatments such as radiotherapy and chemotherapy are often accompanied by adverse reactions such as decreased appetite and digestive absorption disorders, which may lead to malnutrition. Therefore, patients need to maintain a good nutritional and physical condition to support treatment tolerance.

Scientific and reasonable nutritional support can provide essential nutrients for the body, help maintain or improve the patient's nutritional status, physical fitness, and immune function, enable patients to better tolerate anti-tumor treatment, reduce treatment-related adverse reactions, promote tissue repair, which is crucial for overall recovery and quality of life. Deliberately limiting nutrition not only does not help "starve" tumors, but may also harm the patient's own health, weaken treatment tolerance and effectiveness.

Dietary advice for cancer patients: scientific diet, reasonable combination; Properly increasing high-quality protein is important for maintaining immune function, repairing tissue damage, and promoting recovery; Increase intake of unsaturated fatty acids and reduce intake of saturated fatty acids; Eating more fresh fruits and vegetables can help enhance the body's antioxidant capacity and regulate the health of the gut microbiota. Individualized nutrition plans can be developed by consulting a doctor or registered nutritionist based on the condition, treatment type, nutritional status, and individual tolerance.
