Nonetheless, studies on the form of vinegar intake and its effect on defecation are scarce. This cross-sectional study aimed to investigate the association between the frequency of vinegar-based dish intake and defecation status using data from the Tarumizu cohort study. The participants (<jats:italic>n<\/jats:italic>\u2009=\u20091024, 634 women) responded to a health check survey in 2019 using a brief-type self-administered diet history questionnaire. The association between the frequency of vinegar-based dish intake and defecation status was examined using a multivariate logistic regression analysis. Considering confounding factors influencing the defecation status such as sex, age, dietary fiber intake, and medication history, individuals with a habit of eating vinegar-based dishes, such as \u201csour main dishes\u201d (odds ratio [OR]: 1.38; <jats:italic>p<\/jats:italic>\u2009=\u20090.039), \u201csunomono\u201d (OR: 1.49; <jats:italic>p<\/jats:italic>\u2009=\u20090.035), and \u201csalad with sour dressing\u201d (OR: 1.41; <jats:italic>p<\/jats:italic>\u2009=\u20090.049), had a significantly higher defecation frequency. No significant association was observed between the habit of eating vinegar-based dishes and the time required for defecation or straining during defecation. Our study showed that the habit of eating vinegar-based dishes was positively associated with defecation status. Our findings may suggest a novel approach for defecation improvement in people with defecation problems.<\/jats:p>","DOI":"10.1038\/s41598-025-95618-2","type":"journal-article","created":{"date-parts":[[2025,3,29]],"date-time":"2025-03-29T01:59:16Z","timestamp":1743213556000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association between defecation status and the habit of eating vinegar-based dishes in community-dwelling Japanese individuals: a cross-sectional study"],"prefix":"10.1038","volume":"15","author":[{"given":"Yuto","family":"Aoki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin","family":"Kawasoe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takuro","family":"Kubozono","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joto","family":"Yoshimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikiya","family":"Kishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroaki","family":"Kanouchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoko","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuru","family":"Ohishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,3,28]]},"reference":[{"key":"95618_CR1","doi-asserted-by":"crossref","first-page":"938","DOI":"10.1111\/j.1365-2036.2010.04273.x","volume":"31","author":"J Belsey","year":"2010","unstructured":"Belsey, J., Greenfield, S., Candy, D. & Geraint, M.
