New Research Links Processed Meat Consumption to Increased Cancer Risk
Recent studies suggest that consuming processed meats like ham, sausage, and bacon could elevate your risk of developing certain cancers.
While previous health guidelines have linked processed meat to colon cancer, this new study focused on cancers of the upper gastrointestinal tract, an area where the connections have been less clear historically.
Researchers from the European Prospective Study on Cancer and Nutrition (EPIC), one of the largest long-term studies on nutrition and cancer, monitored the health and dietary habits of over 450,000 participants across Europe for about 14 years.
The study included 131,426 men and 318,686 women, as noted in a press release.
During the follow-up, 876 individuals were diagnosed with stomach cancer, while 215 were found to have esophageal adenocarcinoma, a type of cancer affecting the tube connecting the mouth and stomach.
Researchers examined tumor locations in the stomach, differentiating between the upper area near the throat and the lower section. They also categorized the tumors based on cell appearance under a microscope: one type shows a more organized cellular structure, while the other has a dispersed cell distribution.
After adjusting for various lifestyle factors, it was determined that for every 30 grams of processed meat consumed daily, the overall risk of stomach cancer increased by 9%. Additionally, eating an extra 30 grams per day was linked to a 13% rise in the risk of esophageal adenocarcinoma.
According to nutrition data, a regular slice of deli ham or lunch meat typically weighs around 28 grams.
Interestingly, consuming an extra 20 grams of white meats, like chicken or turkey, was associated with a 12% increased risk of stomach cancer as well.
The study also revealed a gender difference. For men, only processed meats showed a clear risk correlation with stomach cancer. However, for women, both processed and white meats contributed to an increased risk.
These findings align with global health standards, particularly those set by the World Health Organization’s International Agency for Research on Cancer, which has classified processed meat as a known human carcinogen, mainly due to its recognized link to colorectal cancer.
Despite this, health agencies have pointed out a less definite connection between processed meats and stomach cancer.
Further research is required to validate these findings and consider other possible risk factors, such as bacteria that could affect dietary impacts on cancer risk.
One limitation of the study is its reliance on participants’ self-reported dietary habits, which may lead to inaccuracies regarding meat consumption.
The study’s results were published in the International Journal of Cancer.
