More data from a
different study at Harvard Medical School published in the Archives of Internal Medicine:
"We found that higher red meat intake may be a risk factor for hormone receptor-positive breast cancer among premenopausal women," said lead author Eunyoung Cho, an assistant professor of medicine at Harvard Medical School.
In this study more than 90,000 women took part in it over a period of 12 years. And again, a modest consumption of red meat (just 1.5 serving per day) showed a marked difference in contracting cancer.
Despite these doubts, Calle agreed that there is an association between red meat and other cancers, such a colorectal cancer. So, she concurs with the American Cancer Society's dietary recommendations to shun red meat.
