In his review of tomatoes, tomato-based products, lycopene, and cancer, Giovannucci (1) notes that, although consumption of tomato sauce and tomatoes had an inverse association with prostate cancer risk, there was no such association with consumption of tomato juice. Does he have any thoughts as to the reason for this apparent inconsistency?
