Patients having cancer have to combat their illness and its complications, but they also have to suffer a list of side effects due to chemotherapy. This article is written to suggest a list of nutritional considerations for chemotherapeutic patients at this stage of the COVID-19 pandemic to enhance their immune system. Nutrition has a decisive role in immune response, specifically in immuno-suppressed patients, such as those undergoing chemotherapy. Due to the complexity of designing a diet for the mentioned patients, we recommend a balanced and varied diet in the COVID-19 pandemic, including zinc, omega-3, vitamin D, whole grains, and skimmed dairy, which were discussed in great detail in the article.</span></span></div> Chemotherapy,Immune System,COVID-19,Cancer Diet,Nutritional Support 0 0 http://mcj.bums.ac.ir/browse.php?a_code=A-10-1-199&slc_lang=en&sid=1 Sarina Salemi 10031947532846005342 10031947532846005342 No School of Nutritional Sciences and Dietetics, Tehran University of Medical Science, Tehran, Iran Moeina Afshari 10031947532846005343 10031947532846005343 Yes Faculty of Medicine in Hradec Kralove, Charles University, Hradec Kralove, Czech Republic.
