We developed recommendations of daily diets for elderly and the elderly patients with chronic diseases during the COVID-19 epidemic, based on the best available evidence and expert experiences. Levels of evidence and recommendations were determined by the method of the Oxford Centre for EBM Levels of Evidence (2001). These urgent recommendations aim to guide staffs in medical institutions to assist the elderly make sensible meal arrangements during this particular period.
