Grapefruit, hormones, and postmenopausal breast cancer risk

This study at the University of Southern California is investigating whether eating grapefruit affects the hormones of postmenopausal women. The researchers were looking to enroll at least 65 volunteers. The Call to Action for this study was sent to Love Research Army members on May 5, 2009. The researchers were able to close enrollment on May 7, 2009, after the Love Research Army provided them with 203 women who were interested in enrolling in the study.
