Cancer itself is a consuming disease, and patients are faced with the problems of restoring health and preventing recurrence and metastasis after receiving various treatments. Therefore, dietary regimen should be considered around the above three points. 1) Dietary supplementation to enhance nutrition. 2) Eat more fresh vegetables and fruits, especially green foods that have anti-cancer, anti-cancer and immunity-enhancing effects. 3) Adhere to the evidence-based diet during the recovery period: “plain tonic”: foods suitable for long-term use by recovered patients, especially for those with deficiency of qi: yam, coix seeds, lentils, lotus seeds, sesame seeds, pine nuts, walnut meat, bird’s nest, silver fungus, poria, hawthorn, wolfberry, chasteberry, tortoise shell gum, gum, cordyceps, party ginseng and princely ginseng. ”Cool tonic”: foods suitable for those who are weak, deficient in yin or deficient in both qi and yin during the recovery period: rhizome, mushroom, banana, raw lotus root, lily, watermelon, bitter melon, purple cabbage, kelp, chrysanthemum, raw groundnut, white peony, mulberry, saxifrage, maitake, basil, dendrobium, bird’s nest, etc. ”Warm tonic”: food suitable for those who are weak and tired of qi, cold and cold limbs during the recovery period: mutton, beef, jujube, yuan meat, almond, peach, yellow meal, sea shrimp, astragalus, atractylodes, cordyceps, etc. Patients who undergo surgical resection, radiation therapy and chemotherapy can lead to malnutrition, weakness, weight loss and reduced resistance. Therefore, after cancer patients undergo anti-cancer treatment, dietary regimen can not only improve patients’ weakness, enhance their resistance to disease, but also speed up their recovery after anti-cancer treatment and delay and stop the recurrence and metastasis of tumors.
