Study Suggests A Possible Link Between High-Starch Diet And Pancreatic Cancer:
"A diet high in starchy foods such as potatoes, rice and white bread may increase the risk of pancreatic cancer in women who are overweight and sedentary, according to a new study by Dana-Farber Cancer Institute, Brigham and Women's Hospital and Harvard School of Public Health researchers.
Published in the Sept. 4 issue of the Journal of the National Cancer Institute, the study suggests that excess insulin – a substance used by the body to process the sugar in foods – can promote the development of pancreatic cancer.
Nearly 30,000 men and women in the United States are diagnosed with pancreatic cancer each year, and an equal number die from it. Pancreatic cancer typically is highly aggressive and is one of the least-curable malignancies. Only four percent of the people with pancreatic cancer are alive five years after diagnosis.
"Our findings add to the growing body of evidence that suggests that insulin may have a role in the development of pancreatic cancer," explains senior author Charles Fuchs, MD, of Dana-Farber. "Further research is needed, however, to track the connection in more detail."
Earlier laboratory studies have demonstrated that insulin encourages the growth of pancreatic cancer cells. Other studies have shown that people who are obese, physically inactive or have adult-onset diabetes mellitus tend to be "insulin resistant," causing them to produce larger-than-normal amounts of insulin to compensate and putting themselves at greater risk for pancreatic cancer. The new study explored whether women whose diets are heavy in foods that increase insulin production are likewise at elevated risk for pancreatic cancer. "
