It is a well-known fact that some patients risk malnutrition due to illness and hospitalisation and that frequent snacks improve poor appetite. The aim of this study was to investigate how patients and staff perceived snacks. The study was a follow-up interview study after an intervention of serving tempting pieces of snacks and having daily talks with a nurse about nutrition during illness. Seventeen patients and 16 nurses were interviewed once. The data, analyzed through qualitative content analysis, were then condensed into three themes: „freedom and joy“, „renewal of appetite“, and „recognition of the significance of food and nutrition during illness“. The snack intervention contributed to a greater attention to food and nutrition among the patients and positively influenced appetite. The nursing staff recognized the significance of snacks, but was hesitant regarding the implementation regarding the daily talks of nutrition with the patients due to a busy working day. Further research is suggested to validate the findings.
