Abstract The incidence of prostate cancer has increased rapidly in recent years. In the world, the incidence of prostate cancer ranks
second among all malignant tumors in men. With the aging of the population and the change of diet, the incidence of prostate cancer in
China has increased rapidly in recent years. Patients with prostate cancer can generally be ingested by mouth during treatment, so there
are few reports on nutritional treatment of patients with prostate cancer. However, patients with prostate cancer will have a variety of related
adverse reactions in the course of long⁃term treatment, which need to be improved through dietary nutrition regulation. Therefore, it is
necessary to screen and evaluate the nutritional risk of prostate cancer patients at different stages of treatment, and select the patients with
nutritional risk and malnutrition for reasonable and targeted nutritional treatment. Dietary nutrition therapy for prostate cancer：① high
fat intake is positively correlated with the risk of prostate cancer; ② a vegan diet helps to reduce the risk of prostate cancer；③ maintaining
a healthy weight and regular physical exercise may contribute to the prevention and treatment of prostate cancer；④ the increase of high⁃fat
milk intake may increase tumor⁃specific mortality in patients with prostate cancer；⑤ it is controversial whether vitamins and minerals
play a role in the prevention and treatment of prostate cancer; ⑥ increasing foods rich in lycopene and tea polyphenols is beneficial to reduce
the risk of prostate cancer; ⑦ diet and nutritional therapy can help to reduce the degree of CRF in patients with surviving tumors.
