One promising and widely studied tool to alleviate these symptoms is a diet restricting fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP). The aim of the study was to assess the relationship between the frequency of consumption of foods high in FODMAPs and the frequency of IBS-like symptoms among recreational runners.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>The study included 153 recreational runners (81 women and 72 men) with a mean age of 37.8 \u00b1 11 years. Most participants reported completing 3\u20134 training sessions per week (54.90%) and running 20\u201340 km per week (37.25%). Training intensity was not objectively assessed. Data were collected using the Computer-Assisted Web Interview method, a standardized questionnaire to assess the frequency of IBS-like symptoms, a proprietary questionnaire to assess behavioral and training factors, and food frequency questionnaire to assess the frequency of consumption of FODMAP-containing products.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Women scored significantly higher than men on the IBS symptom questionnaire (13.11 \u00b1 4.82 vs. 10.71 \u00b1 4.47;\n                      <jats:italic>p<\/jats:italic>\n                      = 0.002).

Gastrointestinal symptoms occurring during training were reported by 18.95% of all participants and were more frequent among men than women (26.39% vs. 12.35%), while post-training symptoms were reported by 12.42% of participants and were also more frequent among men than women (15.28% vs. 9.88%; overall\n                      <jats:italic>p<\/jats:italic>\n                      = 0.01).

The observed differences in symptom severity and the characteristics of training activity suggest that individual factors and gastrointestinal adaptation may play a role in the experience of symptoms. These results provide a starting point for further research that could more precisely determine the mechanisms influencing the occurrence of IBS symptoms in physically active individuals.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fnut.2026.1888737","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T05:34:09Z","timestamp":1785216849000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Frequency of FODMAP-rich products consumption and irritable bowel syndrome-like symptoms among amateur runners"],"prefix":"10.3389","volume":"13","author":[{"given":"Wiktoria","family":"Sta\u015bkiewicz-Bartecka","sequence":"first","affiliation":[{"name":"Department of Food Technology and Quality Evaluation, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]},{"name":"Department of Dietetics, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawe\u0142","family":"Lewandowski","sequence":"additional","affiliation":[{"name":"Department of Food Technology and Quality Evaluation, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]},{"name":"Department of Dietetics, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Ko\u0142odziejczyk","sequence":"additional","affiliation":[{"name":"Department of Food Technology and Quality Evaluation, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]},{"name":"Department of Dietetics, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marek","family":"Kardas","sequence":"additional","affiliation":[{"name":"Department of Food Technology and Quality Evaluation, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]},{"name":"Department of Dietetics, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agata","family":"Kiciak","sequence":"additional","affiliation":[{"name":"Department of Food Technology and Quality Evaluation, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]},{"name":"Department of Dietetics, Faculty of Public Health in Bytom, Medical University of Silesia","place":["Katowice, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.3390\/ijerph17176046","article-title":"Runner\u2019s perceptions of reasons to quit running: influence of gender, age and running-related characteristics.","volume":"17","author":"Menheere","year":"2020","journal-title":"Int J Environ Res Public Health."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1235","DOI":"10.1007\/s40279-022-01651-w","article-title":"Sex differences in endurance running.","volume":"52","author":"Besson","year":"2022","journal-title":"Sports Med."},{"key":"B3","doi-asserted-by":"publisher","first-page":"898","DOI":"10.1136\/bjsports-2018-100493","article-title":"Is running associated with a lower risk of all-cause, cardiovascular and cancer mortality, and is the more the better?
