Interesting to spot this abstract which - as far as I read it - indicates that intakes of available carbohydrate, glycemic load and sucrose are associated with elevated risks for pancreatic cancer, while fat - particularly saturated fat - intake is associated with diminished risks.
Available Carbohydrates, Glycemic Load, and Pancreatic Cancer: Is There a Link?
I haven't seen the full study (does anyone have it?) so I am not sure why the abstract finishes with the statement:
Rather than being causal, the short-term increase in pancreatic cancer risk associated with high available carbohydrate and low fat intake may be capturing dietary changes associated with subclinical disease.So they are saying that subclinical pancreatic cancer makes you eat more carbs and less fat!
