Can overcooking meat cause cancer?
A recent study led by E. M. John and colleagues of the Cancer Prevention Institute of California in Fremont, California found some types of meats and cooking methods were associated with increased risk of prostate cancer.
High temperature cooking methods like grilling and barbecuing have been already known to generate cancer-causing carcinogenic heterocyclic amines and polycyclic aromatic hydrocarbons. The current study adds to a growing body of evidence to suggest that meats cooked at higher temperature can be a risk factor for prostate cancer.
For the study, the researchers analyzed dietary information from 531 men with newly diagnosed advanced cases and 195 localized cases of prostate cancer and 527 men without this cancer and examined the association between consumption of meats and risk of prostate cancer.
Higher consumption of hamburgers, processed meat, grilled red meat, and well-done red meat were found associated with 79 percent, 57 percent, 63 percent, and 52 percent increased risk, respectively, of developing advanced but not localized prostate cancer.
The researchers did not find any association between consumption of white meat and prostate cancer risk.
The study was published in the April 2011 issue of Nutrition and Cancer.
Another recent study showed, drinking coffee, decaffeinated or not, may reduce risk for developing advanced prostate cancer, which is often times lethal.The study led by Kathryn Wilson of Harvard School of Public Health and colleagues showed men who drank six or more cups of coffee were at 60 percent reduced risk for contracting advanced prostate cancer.
The epidemiological study published on May 17 2011 online in the Journal of the National Cancer Institute, is observational, meaning drinking coffee may not be the cause for the reduced risk for the malignancy. It's too easy to recommend drinking coffee as a measure protective against prostate cancer, a health observer suggested.
