According to the study, people whose diets had a higher amount of foods loaded with these antioxidants were two-thirds less likely to develop pancreatic cancer when compared to people who had the least amount of these nutrients in their diets.
The study is published online in the journal Gut.
Antioxidants are vitamins, minerals, and other nutrients that protect cells from the damage of "free radicals." Free radicals are destructive fragments of oxygen that have been linked to cancer and other diseases. The new findings show an association between these foods and pancreatic cancer risk, but they do not tell us if or how antioxidants actually prevent pancreatic cancer.
"Vitamins C and E and selenium are good for your general health. And it may be that they help to prevent against pancreatic cancer as well. But more study is needed before we can say that for sure," says study researcher Andrew R. Hart, MD. He is a senior lecturer in gastroenterology at Norwich Medical School in East Anglia, Norwich, U.K.
If this association turns out to be causal, antioxidants may help prevent as many as one in 12 cases of pancreatic cancer. The American Cancer Society estimates that about 43,920 people will be diagnosed with pancreatic cancer in 2012. About 37,390 people will die from the disease.
