Red Meat Consumption Shown to Increase Risk of Breast Cancer
Eating high amounts of red meat has been associated with a higher
risk of type 2 diabetes, coronary heart disease, and stroke. Now a new study
suggests that red meat consumption may also increase the risk of breast cancer.
The researchers looked at consumption of different meat
categories for 42,012 women who participated in the Sister Study. The women
were followed for an average of 7.6 years, and all incidences of breast cancer
Women who consumed the highest amount of red meat were found to
have a 23% higher risk of invasive breast cancer compared to women who consumed
the least amount. In contrast, women who consumed the highest amount of poultry
had a 15% lower risk of invasive breast cancer compared to those who ate the
least amount. Women who substituted red meat for poultry also had a decreased risk
of breast cancer.
The study was conducted by researchers from Columbia University
and the National University of Singapore. It was published online ahead of
print on August 6, 2019 in the International
Journal of Cancer.
