A fresh report published in the Journal of the National Cancer Institute shows that a diet rich in fat from red meat and dairy can increase your risk of pancreatic cancer.
Pancreatic cancer is on the fourth place of deaths caused by cancer in the U.S. and some of the known connections to developing it are obesity, diabetes and smoking. The American Cancer Society estimates that over 45,000 people in the U.S. will be diagnosed with pancreatic cancer in 2009 and out of those, around 35,000 will not survive.
1,337 men and women developed pancreatic cancer during the study. According to the results, a diet with high amounts of total fats gave a 53 % higher risk of pancreatic cancer among men and 23 % higher risk among women, compared to men and women who had the lowest-fat diets. The risk for both men and women who had a high intake of saturated fats from animal sources was increased by 36 %, compared to those with low intakes.
Earlier research on the correlation between dietary fat from animals and pancreatic cancer has given inconclusive results, but with this study there is new proof.
According to Health News, the strategic director of pharmacoepidemiology at the American Cancer Society, Eric J. Jacobs said that the study "provides important evidence that a diet high in animal fat may increase risk of one of the leading causes of cancer death." And, "While further confirmatory research about animal fat and pancreatic cancer is still needed, results of this study support the American Cancer Society's recommendations to limit red meat and emphasize plant foods to help reduce risk of a variety of cancers."

The Scrutiny, Epidemiology, and End Results cancer registry data were linked with the Medicare Health Outcomes Survey (MHOS) data; data were collected from Medicare beneficiaries who were aged 65 years and older from 1998 through 2003. Cancer patients (n = 1432; with prostate, breast, colorectal, lung, bladder, endometrial, or kidney cancers; melanoma; or non-Hodgkin lymphoma [NHL]) were selected whose first cancer diagnosis occurred between their baseline and follow-up MHOS assessments. Control subjects without cancer (n = 7160) were matched to cancer patients by use of propensity scores that were estimated from demographics and comorbid medical conditions.
Patients with all cancer types (except melanoma and endometrial cancer) reported statistically considerable declines in physical health (mean scores: prostate cancer = -3.4, 95% confidence interval [CI] = -2.5 to -4.2; breast cancer = -3.5, 95% CI = -2.5 to -4.5; bladder cancer = -4.3, 95% CI = -2.5 to -6.1; colorectal cancer = -4.4, 95% CI = -3.3 to -5.5; kidney cancer = -5.7, 95% CI = -3.2 to -8.2; NHL = -6.7, 95% CI = -4.4 to -9.1; and lung cancer = -7.5, 95% CI = -5.9 to -9.2) compared with the control subjects (mean score = -1.8, 95% CI = -1.6 to -2.0) (all P < .05).
These findings provide validation of the specific venomous effects of cancer on HRQOL and an evidence base for future research and clinical interventions aimed at understanding and remediating these effects.
