Background and aims: Fruits and vegetables are rich in fiber and a good source of anti-inflammatory and immune-boosting vitamins, minerals, and antioxidants. We investigated the association between fruits, vegetables, and fiber intake and severity of COVID-and related symptoms in hospitalized patients. Methods: A total of COVID-hospitalized patients aged to years were recruited for this cross-sectional study in Kashan, Iran, between June and September of . Dietary intakes were assessed using an online validated -item food frequency questionnaire (FFQ). COVIDseverity and symptoms were evaluated using the National Institutes of Health (NIH) COVID-Treatment Guidelines. Moreover, we examined COVIDsymptoms, inflammatory biomarkers, and additional factors. Results: The mean age of participants was . ± . years, and % had severe COVID-. Patients with higher consumption of fruits (OR: . ; % CI: . -. , P-trend < . ), vegetables (OR: . ; % CI: . -. , P-trend < . ), and dietary fiber (OR: . ; % CI: . -. , P-trend < . ) had lower odds of having severe COVID-. In addition, they had shorter hospitalization and convalescence periods, lower serum C-reactive protein (CRP), and a reduced risk of developing COVID-symptoms such as sore throat, nausea and vomiting, dyspnea, myalgia, cough, weakness, fever, and chills.
