Study links processed meat consumption to increased cancer risks

A long-term study published in the International Journal of Cancer has identified links between meat consumption and increased risks of certain cancers. Researchers monitored the dietary habits and health of 450,112 individuals for an average of 14 years.

The findings indicate that consuming an additional 30 grams of processed meat daily is associated with a 9 percent higher risk of stomach cancer and a 13 percent higher risk of esophageal adenocarcinoma. Notably, the study did not find a statistically significant link between unprocessed red meat and these specific cancers.

In a surprising finding, the research highlighted a connection between white meat consumption and cancer risk specifically in women. For women, every additional 20 grams of white meat consumed daily was linked to approximately a 20 percent increase in the risk of cancer in the middle and lower parts of the stomach. This specific correlation was not observed in men.

Scientists suggest that compounds formed during digestion may damage DNA and increase oxidative stress. Additionally, processing methods, storage, and high salt content in processed meats may contribute to risks by irritating the stomach lining and causing inflammation.
