Researchers from the in the US studied the effects of versus corn-based diets on rats selectively bred to have low fitness levels.

The found that in may not only counter the negative effects of on bone and metabolic health, but also have positive impacts on bone strength for women who have not yet reached

"The findings suggest that all women might see improved bone strength by adding some soy-based whole foods, such as and soy milk, to their diet," said Pamela Hinton, a at

The rats were divided between those with and without ovaries to mimic effects of Prior research has found that these rats are good models for menopausal women.

They compared the impact of the soy diet on bone strength and metabolic function to rats fed a corn-based, soy-free diet.

"As such, understanding how dietary protein sources, such as soy, can impact metabolism and bone in these rats can help us better understand how such diets might impact women's health across the lifespan," said Victoria Vieira-Potter, an associate at

The researchers found that the tibia bones of the rats that were fed soy were stronger compared to the rats who were fed the corn-based diet, regardless of ovarian hormone status.

Moreover, they found that the soy-based diet also improved metabolic function of the rats both with and without ovaries.
