Chemotherapy is an intensive cancer treatment that kills both healthy and cancer cells. As a result, cancer patients often suffer weight, hair and appetite loss in addition to immune system stress as it tries to recover from the treatment. According to the University of Pennsylvania Abramson Cancer Center, chemotherapy also lowers a patient's white blood cell count, which leaves the body more susceptible to various infections. Doctors will often prescribe neutripenic diet or other dietary programs to help patients avoid foods that may cause food-borne illnesses and reduce the recovery process.
Soft Cheeses
According to the University of Pennsylvania Abramson Cancer Center, those undergoing chemotherapy treatments should avoid most soft cheeses. Soft cheeses and blue-veined cheeses are often ripened by mold, which carry higher contamination risks that may cause food-borne illnesses in those wit weak immune systems. Examples of soft cheese to avoid include Stilton, gorgonzola, brie and any blue cheese.
Raw Vegetables
Despite being full of minerals and vitamins, raw unwashed vegetables should be avoided during chemotherapy treatment since they are likely to harbor bacteria and microorganisms, according to the American Cancer Society. After chemotherapy treatments, a patient's immune system is weak and susceptible to infection from pathogens. However, patients with low white blood cell counts are permitted to eat fresh vegetables if they are thoroughly washed and then boiled, baked or microwaved. This process kills all agents that could potentially lead to contamination.
Raw and Undercooked Meats
Anyone undergoing chemotherapy should avoid eating sushi while undergoing treatment. Raw meats like sushi often contain extremely high amounts of bacteria such as Listeria, which can cause flu-like symptoms and bacterial infection. The University of Pennsylvania Abramson Cancer Center reports that patients receiving chemotherapy are often unable to fight off infections because the treatments temporarily weaken the immune system. The National Cancer Institute recommends those with compromised immune systems only eat meats that are thoroughly cooked until well done.
