Prostate cancer risk was examined in relation to intakes of fruit, vegetables, beta-carotene and retinol. Subjects were a cohort of 1985 men previously to asbestos who participated in a cancer prevention programme of beta-carotene and retinol supplements that commenced in July 1990. Diet was assessed at entry to the programme. Ninety-seven cases of prostate cancer were identified during follow-up until the end of 2004. A decreased prostate cancer risk was observed with increasing intakes of vitamin C-rich vegetables, including bell peppers and broccoli. Fruit, other vegetables and vitamin A intakes did not appear to be strong factors in the development of prostate cancer in this study.Prostate Cancer and Prostatic Diseases advance online publication, 22 May 2007; doi:10.1038/sj.pcan.4500979.
