The study investigated the association of dietary fat consumption with the risk of breast cancer. The dietary histories of 18,586 postmenopausal women were analysed over a seven year period.
Regarding saturated fat consumption, the study found that for every 10 gram per day increase in saturated fat there was a 10% reduction in the risk of breast cancer.
