Chemical treatment can cause bone marrow regeneration, especially the decrease of white blood cells. In order to effectively prevent the blood count from declining, patients should supplement high-protein diets during chemotherapy, such as milk, soybeans, lean meat, pig's trotters, sea cucumbers, fish, animal livers, red dates, peanuts, walnuts, black fungus, carrots, adzuki beans, etc. River crabs, snakeheaded fish, beef, and peptones made from animals such as donkey hide gelatin (donkey hide gelatin), pig skin gelatin (pork skin peptone), etc. can also help increase white blood cells. Traditional Chinese medicine attaches great importance to replenishing the internal organs with internal organs, so during chemotherapy, animal bone marrow can also be added in appropriate amounts, such as stewing and blanching beef, sample, and pig bone marrow, or diets made with chicken blood, duck blood, goose blood, and pig blood. At the same time, you can also eat more five black foods, such as black sesame seeds, black rice, black beans, black dates, etc. Traditional Chinese medicine believes that "black can enter the kidneys" and the five black foods can nourish the kidneys and marrow and help improve the blood count.
