The Times of India reported that at the recent American Society of Clinical Oncology annual meeting, research from Northwestern Memorial Hospital in the U.S. indicated that many foods may have side effects when combined with chemotherapy, and therefore, patients undergoing chemotherapy are advised not to self-prescribe dietary therapies without professional guidance.
Dr. McCoy, a geriatrics specialist who led the study, pointed out that many patients undergoing chemotherapy are taking herbal supplements, believing they are more natural and free of side effects. This idea is incorrect. For instance, turmeric, garlic, and fennel are safe when used in small amounts for cooking. However, if consumed in large quantities over a long period, some can interfere with drug metabolism, thereby affecting the drug's efficacy. Others, such as garlic, can increase the risk of bleeding during surgery.
Nevertheless, chemotherapy often causes severe gastrointestinal reactions in patients, such as nausea, vomiting, and loss of appetite, making dietary management crucial. A well-planned diet directly impacts the smooth progress of chemotherapy. Generally, patients undergoing chemotherapy should consume more high-protein, vitamin-rich, yet light foods, such as eggs, nuts, and legumes. Additionally, foods rich in antioxidants, like pumpkin and carrots, should be supplemented. Spicy, fried, and high-sugar foods should be avoided. Furthermore, to stimulate appetite, one can drink a small glass of an acidic beverage before a meal to whet the appetite, or supplement with adequate zinc and vitamin B to improve the sense of taste.
