- Dietary vitamin B6. B12 and folate, may decrease pancreatic cancer risk among lean people

Researchers exploring the notion that certain nutrients might protect against pancreatic cancer found that lean individuals who got most of these nutrients from food were protected against developing cancer. The study also suggests this protective effect does not hold true if the nutrients come from vitamin supplements.
