Introduction: knowledge about nutrition in nursing university students is a topic of great significance in the education of future healthcare professionals, as they are the ones who provide support and education to patients in matters related to diet and nutrition.Objective: to assess the level of knowledge about nutrition in nursing university students from a public university in Peru.Methods: a quantitative approach was employed, utilizing a non-experimental research design of a cross-sectional descriptive nature. The sample consisted of 175 students who were administered the Nutrition Knowledge Questionnaire, an instrument with appropriate metric properties.Results: it was found that among the nursing students, 40 % had a low level of knowledge about nutrition, while 37,7 % demonstrated a level considered moderate, and 22,3 % exhibited a high level of nutritional knowledge. Furthermore, it was observed that the level of knowledge about nutrition was significantly associated with both the students' gender and the year of their studies (p<0,05).Conclusions: nursing university students from a public university in Peru were characterized by having low levels of knowledge about nutrition. Therefore, it is necessary to review and update the curriculum of the Nursing program to incorporate nutrition courses in a more comprehensive and up-to-date manner. This will ensure that students receive a strong foundation in this field from the beginning of their studies
