A New Look at Soy to Prevent Osteoporosis

A New Look at Soy to Prevent Osteoporosis

Scientists have determined that soy during early formative years may protect against bone loss later in life. Their surprising findings were published in the journal of the Federation of American Societies for Experimental Biology (The FASEB Journal).

Female lab rats were used as test subjects. One group was fed a soy-based diet for 30 days (from day 24 after being born to day 55), and then the group was switched to a standard diet until 6 months of age. Afterward, the ovaries of the rats were removed in order to mirror postmenopausal bone loss in women to determine the amount of bone loss.

In the second group, the rats were fed a standard diet throughout their lives. This group also had their ovaries removed to mimic postmenopausal bone loss, and analyzed to determine bone loss.

The researchers said the results were clear: The first group of rats lost less bone mass compared to the second group of rats.

Jin-Ran Chen, M.D., Ph.D., a researcher in the study from the Skeletal Development Laboratory at Arkansas Children's Nutrition Center at the University of Arkansas in Little Rock, directly attributed the benefits of soy in early childhood to healthy bones later in life: "Appropriate early-life nutrition can optimize peak bone mass. Consumption of soy foods has a variety of health benefits, including amelioration of bone loss during adulthood."

It bears noting that the study reports only animal findings and does not address issues such as hot flashes in postmenopausal women. In fact, some studies have shown soy offers no relief from some postmenopausal symptoms.

Other benefits of soy are widely known: Soy is an excellent plant source of all eight essential amino acids, making it the only complete nonanimal protein. Soy is also a source of fiber, omega-3 acids, B vitamins, and calcium.
