Editing Prostate Cancer: Prevention (section)

== ‎Lycopene ==
* A red-orange carotenoid found primarily in tomatoes and tomato-derived products including tomato sauce, tomato paste, and ketchup, and other red fruits and vegetables.
* In an in vivo model in which male rats were treated with N-methyl-N-nitrosourea and testosterone to induce prostate cancer, a protective effect was observed for both calorie restriction and tomato powder but not pure lycopene. This observation suggests that tomato products contain compounds in addition to lycopene that modify prostate carcinogenesis and that reduced caloric consumption and a diet rich in tomato-based foods may be more beneficial than taking oral lycopene supplements in reducing the risk of prostate cancer.
* Meta-analysis of 3 RCTs found no association of lycopene on prostate cancer risk
