Objective: This study was planned to investigate whether bariatric surgery (BS) has an impact on nutritional literacy. Materials and Methods: The research is an experimental type case-control study. The study consists of thirty-person experimental and control groups. The data were obtained by using the questionnaire form developed by the researchers and the “Nutrition Literacy Scale”. Results: The average age of the case group was 36±7.79 and 53.3% were women. The mean age of the control group was 34.5±8.35, 56.7% were women. The total nutrition literacy score before BS was 20.10±5.68 and the total postoperative nutrition literacy score was 29.57±3.07. The total nutrition literacy score of the control group was 23.73±6.18. After BS, a statistically significant difference was found between the nutritional literacy total score of the experimental group and the control group. There was no significant relationship between nutrition literacy and characteristics (except education level and level of knowledge about nutrition). However, there was a significant negative correlation between the nutritional level of nutrition and nutrition literacy before BS. After BS, only a statistically significant relationship was found between education level and nutrition literacy. Conclusions: It was concluded that bariatric surgery had a positive effect on nutritional literacy. It can be said that individuals who have undergone bariatric surgery are more researchers about nutrition.
