Abstract: Hospitals have a responsibility to link human health and the environment, but food waste in hospitals has traditionally been much higher than in other areas of food supply. The cause of this situation has many negative impacts on health, economy, society, and environment. As a result, food waste has become a topic of discussion in hospital food departments. Part of this problem is plate waste, the served food that remains uneaten by patients. Given the magnitude of the food problem, this systematic review is aimed to identify the most common measures used to reduce plate waste in hospitals. PubMed, Scopus, and Google Scholar databases were comprehensively searched to identify food waste studies worldwide using related search terms. Many approaches have been recommended to increase patient food intake and minimise plate waste in hospitals. Up to date, the four most common include flexible portion sizes, increased food choices through selective menus, additional nutritional support and a better ordering and delivery system. Among them, the most used and effective are flexible portion sizes which may increase the ability of patients choosing their menus and upgrade ordering and delivery system by electronic format. In most studies, plate waste covers the most significant percentage of food waste produced in hospitals, while more than one approach is recommended to minimise it. In this aspect, further well‐design, multicenter, clinical studies are strongly required to highlight and establish novel and effective approaches for improving food waste management in hospitals by reducing plate waste.
