I'll keep this short because it's waaaaaay past my bedtime, but they drew these conclusions by doing a meta-analysis on eleven studies that used food recall questionnaires. What a waste of time and money.
I'll bet not one of those studies asked how much wheat they ate, or considered macro-nutrient intake. Of course not, because it's all a bunch of BS. They want us all to be vegan but eat Monsanto's genetically engineered crap while we're at it.
The latest study, published in the British Journal of Cancer, is from researchers at the respected Karolinska Institute in Stockholm, Sweden. [Respected? By whom?]
They examined data from 11 studies, including 6,643 cases of pancreatic cancer.
