High-veg diet 'wards off [pancreatic] cancer'

The basic concept will come as no shock to anyone here, however the fine print is interesting:

Raw vegetables were found to be more protective than cooked ones, the study said after conducting interviews with 532 people with the cancer, and 1,700 people who did not have the disease.

But researchers acknowledged the results may have been influenced by food which may often be eaten with the vegetables.

It is the first preventive nutrition study I have seen that specifically touts the benefits of raw over cooked food. While I have fairly dismissive of this idea in the past, this could very well have something to do with vegetable enzymes. Several vegetable based enzymes have been shown to have anti-cancer and anti-inflammatory effects, such as bromelain and papain. However, it has long been in dispute whether such enzymes were active in the human body when orally ingested as part of normal foodstuffs (as opposed to enteric coated capsules).
