Large review on soy
Soy helps bones in other research
This is confirmed by a 2012 analysis of multiple studies from Sichuan University’s Hainan Medical College.
The researchers analyzed multiple published international clinical studies on the application of soy isoflavones to prevent osteoporosis, the central cause of hip fractures and other bone fractures around the world.
In their meta-analysis of the research, the medical researchers found that soy isoflavones increased bone density by 54% while reducing bone loss by 23% as measured by a bone loss marker called deoxypyridinoline, which is found in the urine, especially at higher levels among those women in postmenopause.
The research found that doses above 75 milligrams a day of soy isoflavones had the most effect among postmenopausal women.
Osteoporosis is the leading cause of disability among the elderly. Nearly half of women over 60 will have a hip fracture among industrialized nations.
Active phytoestrogens within soy isoflavones include genistein and daidzein. They are also found among many types of peas, beans, nuts and whole grains.

Case Adams is a California Naturopath with a PhD in Natural Health Sciences, and a Board Certified Alternative Medicine Practitioner. He has authored 26 books on natural healing strategies. “My journey into writing about alternative medicine began about 9:30 one evening after I finished with a patient at the clinic I practiced at over a decade ago. I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn our health around. As I drove home that night, I realized this knowledge should be available to more people. So I began writing about health with a mission to reach those who desperately need this information. The strategies in my books and articles are backed by scientific evidence along with wisdom handed down through traditional medicines for thousands of years.”
