It is estimated that 30% to 50% of pancreatic cancers may be attributable to dietary factors. Both butter consumption and saturated fat intake were positively associated with pancreatic cancer.Processed meats have been linked to the development of PDA (Pancreatic Ductal Adenocarcinoma or in simple words pancreatic cancer). In a prospective study of more than 200,000 people, 482 individuals developed PDA during 7 years of follow-up (Nöthlings et al, 2007). Those who had consumed the greatest amount of processed meats had a 67% increased risk of Pancreatic cancer. Diets laden with pork and red meat intake were associated with a 50% increase in pancreatic cancer risk, but poultry, fish, dairy product, and egg consumption conferred no additional risk. This comes directly from Blumgart book for hepatobiliary surgery, most reputed book in the field.
After partial pancreatectomy or in general to avoid high sugar, best is to take high protein and low carb diet. Stay away from free sugar like candy, soda, juice, cake, muffin etc.....you know what I mean. Instead take fresh fruits, vegetables, avoid canned or smoked food. Exercise every day and you will be fine.
