- Study was conducted to assess whether poultry or red meat consumption was the contributary factor for breast cancer
- Women who consumed red meat had 23% higher risk for breast cancer
- Women who consumed poultry had 15% lower risk of breast cancer
- Evidence suggests that consuming poultry reduced incidence of breast cancer
Consumption of red meat increases the risk of cancer. However, a new study suggests that by replacing red meat with poultry can reduce the incidence of breast cancer.
Essence of the Study
Results from a new study suggest that red meat consumption may increase the risk of breast cancer, whereas poultry consumption may be protective against breast cancer risk. The findings are published in the International Journal of Cancer.
Findings of the Study:
During follow-up, 1,536 invasive breast cancers were diagnosed. Increasing consumption of red meat was associated with increased risk of invasive breast cancer: women who consumed the highest amount of red meat had a 23% higher risk compared with women who consumed the lowest amount. Conversely, increasing consumption of poultry was associated with decreased invasive breast cancer risk: women with the highest consumption had a 15% lower risk than those with the lowest consumption. Breast cancer was reduced even further for women who substituted poultry for meat.
Analysis Controlled for Other Factors
The findings did not change when analyses controlled for known breast cancer risk factors or potential confounding factors such as race, socioeconomic status, obesity, physical activity, alcohol consumption, and other dietary factors. No associations were observed for cooking practices or chemicals formed when cooking meat at high temperature.
Conclusion of the Study
"Red meat has been identified as a probable carcinogen. Our study adds further evidence that red meat consumption may be associated with increased risk of breast cancer whereas poultry was associated with decreased risk," said senior author Dale P. Sandler, PhD, of the National Institute of Environmental Health Sciences. "While the mechanism through which poultry consumption decreases breast cancer risk is not clear, our study does provide evidence that substituting poultry for red meat may be a simple change that can help reduce the incidence of breast cancer."
