Since not all plant-based foods are equally healthy, it is essential to distinguish between healthful and unhealthful plant-based options. This study aimed to analyse the associations between different plant-based dietary patterns and the incidence of obesity-related cancers. We followed-up 16\u00a0256 participants from the \u2018Seguimiento Universidad de Navarra\u2019 prospective cohort. Based on a validated FFQ, we calculated adapted overall, healthful and unhealthful plant-based diet index scores. Scores were assessed at baseline and repeatedly after 10 years of follow-up. Hazard ratios (HR) and 95 % CI were estimated using multivariable-adjusted time-dependent Cox regression models. After a median follow-up of 13 years, 221 incident obesity-related cancer cases were confirmed. Overall plant-based and unhealthful plant-based dietary patterns showed no association. Contrarily, participants in the highest tertile of the healthful plant-based diet score had a lower obesity-related cancer risk (HR\n T3vsT1<\/jats:sub>\n 0\u00b767; 95 % CI, 0\u00b747, 0\u00b797;\n P<\/jats:italic>\n trend<\/jats:sub>\n = 0\u00b7031). This association persisted after updating dietary information at 10-year follow-up (HR\n T3vsT1<\/jats:sub>\n 0\u00b768; 95 % CI, 0\u00b747, 0\u00b799;\n P<\/jats:italic>\n trend<\/jats:sub>\n = 0\u00b7037) and was stronger for women (HR\n T3vsT1<\/jats:sub>\n 0\u00b752; 95 % CI, 0\u00b732, 0\u00b786;\n p<\/jats:italic>\n interaction<\/jats:sub>\n = 0\u00b704). In this large prospective cohort, greater alignment with a healthful plant-based dietary pattern was associated with a decreased risk of obesity-related cancer, whereas alignment with overall and unhealthful plant-based dietary patterns showed no association.\n
