Red Meat and Dairy Products.
As part of the National Institutes of Health-AARP Diet and Health Study, researchers analyzed the diets of 525,000 participants to determine whether there is an association between dietary fat and pancreatic cancer. This study showed that consuming fat from red meat and dairy products is associated with increased risk of pancreatic cancer. There was no association between plant-food fat and pancreatic cancer.

I am not currently a vegetarian, although once upon a time I was a raw vegan. This finding is not going to make me go back, but it is an interesting association that will make me monitor the intake of red meat and dairy products and make sure that they are coming from clean organic sources. I would suggest you do the same.
