Some 44 million Americans, mostly older women, are at risk of osteoporosis, a condition that can lead to fragility, low bone mass, structural deterioration of bone tissue and increased susceptibility to fractures.

And while the number of people at risk is projected to sky-rocket to more than 61 million by 2020, researchers may have dug up a ray of hope: Besides causing bad breath and adding flavor to food, white onions may help prevent osteoporosis, as a chemical found within the vegetable appeared to decrease bone loss in rat bone cells.

Onion's Influence on Rat Bone Cells

In analyzing the active chemical components of white onions, researchers found the most likely compound accountable for the decreased bone loss was glutamyl peptides, GPCS. (Peptides are the family of molecules formed from the linking, in a defined order, of various amino acids.)

In the study, researchers exposed isolated bone cells from newborn rats to parathyroid hormone -- a parathyroid gland secretion, which regulates calcium and phosphorous levels in the body -- to promote bone loss. They then exposed some of the treated cells to GPCS. It was discovered that rats treated with GPCS from white onions were significantly less likely to lose bone minerals than those not exposed to the chemical.

Though the findings appear promising, additional studies are needed to determine if GPCS will have a similar effect in humans.
