Introduction: nutrition of cancer patients is a frequently discussed topic. Tumor growth is conditioned by the production of pro-inflammatory cytokines in the body, which leads to metabolic changes and the development of tumor cachexia syndrome. Immunomodulatory nutrition and efforts to at least partially control inflammation are essential in cancer. Aim of the study: The aim of the study was to evaluate the dietary intake of omega-3 fatty acids in the diet of cancer patients and to analyse the main dietary sources of these polyunsaturated acids. Research Methods: In this observational and questionnaire-based non-interventional study, 10 respondents who had not shown signs of cancer for more than a year, were older than 18 years and according to the highest frequency of cancer incidence were selected. Results: The average daily intake of omega-3 FAs in the study group was 1.59 g/day for both sexes, which represents 53% of the recommended therapeutic dose of 3 g/day (DLD). In contrast, the average daily intake of omega-3 FAs in men was found to be 1.47 g/day, corresponding to 49 % of the DLD. Conclusion: Analysis of the dietary intake of cancer patients in remission suggested that their intake of omega 3 fatty acids is minimal and does not even reach the recommended values for the general...
