Study: High Saturated Fat Intake Linked to Breast Cancer Risk
An eye-opening study was published Wednesday online in the Journal of the National Cancer Institute. Researchers from the National Cancer Institute in Milan found that women who eat a diet high in saturated fat may be at an increased risk for several types of breast cancer.
Fox News reported on the study this week and spoke to study researcher Sabina Sieri, who said, “This study indicates that a diet high in saturated fat increases breast cancer risk, and most conspicuously, it suggests that saturated fat intake is involved in the causation of three subtypes of cancer.” Though Sieri’s study didn’t mark a specific “threshold” level of fat intake that raises a woman’s risk of breast cancer, she recommended that women not let their saturated fat intake exceed more than 10 percent of their daily diet.
According to Fox News, Sieri and her team conducted their research by studying data from 337,000 women, ages 20 to 70, in 10 countries in Europe. The study participants were followed for an average of 11.5 years, and what researchers found was that those women whose diets included a large amount of saturated fat from animal products were more likely to develop certain types of breast cancer, compared with those whose did not.
After having the women complete dietary and lifestyle questionnaires at the beginning of the study, the researchers followed the participants for and found that after that time, 10,062 women in the study, or 3 percent, had developed breast cancer.
