Soy vs. corn gluten--who cares?

Soy diets might increase women's bone strength

Researchers now have discovered through a new animal study that soy protein found in food might counter the negative effects of menopause on bone and metabolic health. Moreover, the researchers believe that soy protein might also have positive impacts on bone strength for women who have not yet reached menopause.

Osteoporosis, decreased physical activity and weight gain are serious health concerns for postmenopausal women. Researchers from the University of Missouri now have discovered through a new animal study that soy protein found in food might counter the negative effects of menopause on bone and metabolic health. Moreover, the researchers believe that soy protein might also have positive impacts on bone strength for women who have not yet reached menopause.

"The findings suggest that all women might see improved bone strength by adding some soy-based whole foods, such as tofu and soy milk, to their diet," said Pamela Hinton, professor of nutrition and exercise physiology. "We also believe that soy-based diets can improve metabolic function for postmenopausal women."

Hinton and Victoria Vieira-Potter, co-author and associate professor of nutrition and exercise physiology, studied the effects of soy versus corn-based diets on rats selectively bred to have low fitness levels. Rats were again divided between those with and without ovaries to mimic effects of menopause. 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.

"Prior research has shown that these rats are good models, as average American women are relatively inactive both before, and especially after, menopause," Vieira-Potter said. "As such, understanding how dietary protein sources, such as soy, can impact metabolism and bone health in these rats can help us better understand how such diets might impact women's health across the lifespan."

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.

"Bottom line, this study showed that women might improve bone strength by adding some soy-based whole foods to their diet," Hinton said. "Our findings suggest that women don't even need to eat as much soy as is found in typical Asian diets, but adding some tofu or other soy, for example foods found in vegetarian diets, could help strengthen bones."

What this is--relatively complete soy protein put up against corn gluten that had to be supplemented with methionine and lysine. So you've got a comparable essential amino acid profile, but with the corn gluten, the methionine and lysine are there, easily absorbed early on, where with the soy, they're slowly released during digestion along with the other essential amino acids. Pretty much the last thing this study says is anything actionable--unless somebody out there has been living on amino acid supplemented corn gluten and is willing to switch to soy.

Just how much soy does she think is in the Asian diet? The mouse diet was 26 percent soy meal by weight, a massive portion of the diet.

No conflicts of interest--other than the general societal bias for foods like soy. :p

It's sad that they waste money on these useless studies but there's never enough money to do the important studies.

Anyone who does not want to increase risk of hormonal cancer growth should care. As vegetarians continue to try to rehabilitate soy's reputation and write that moderate amounts of unprocessed soy (no soy milk or veggie burgers where Americans often get their soy) do not increase cancer risk, I have yet to see a study that refutes this one from MD Anderson. Eating Soy May Turn on Genes Linked to Cancer Growth https://www.breastcancer.org/resear...inked-to-cancer. If you don’t eat processed foods, rarely eat out, eliminating soy in all its forms is easy. No thanks, I’ll have a steak to strengthen my bones. :)

In this study, as the information was presented in the above article that Janet linked, I see a problem: the recommendation for eating soy in moderation has no basis.

The results showed that several genes that encourage cell growth were turned on in women in the soy protein group.

what kind of growth? repairative? regenerative? protective? This wasnt even considered.

Quote:

The study didn’t last long enough to know whether these genetic changes would cause cancer to grow.

Quote:

The study also didn’t look at:

1. whether soy does or doesn’t reduce the risk of breast cancer
2. whether eating soy would have any effect on women who don’t have breast cancer or who have non-cancerous breast lesions

This statement is overlooked in favor of jumping to the researchers recommendation----which has no basis.

Quote:

The researchers didn’t recommend that women avoid soy. But they did say that soy should be eaten in moderation.

They use the " moderation" fall back which has NO support in this study to fit their beleives, or to err on the safe side. WHat if soy could be a means to prevent breast cancer?

This study doesnot tell me anything about the relationship between soy and breast cancer that I can see.

https://www.breastcancer.org/tips/n...t/diet_warnings

Looking thru this website I cannot find any mention of TWO studies that conclusively show the effects of chemo and radiation is significantly improved IF several days of keto overlap the treatment.

The mention of several treatments using foods are followed by a bold statement that these have not been verified by any study. My question is "WHY NOT?"

If reserchers jump to the conclusion that moderate consumption of soy is their current recommendation, how can these food based cured be relegated to 'dont try' these because there is no study to prove they work" . The " dont try" is implied in the BOLD statement regarding study status.

yup!!!!!!!!!!
