This info from Wikipedia is what I'd call "controversial"--I guess you wouldn't so
Soy is controversial. For it to be used as an additive in foods at this point is questionable. And it's all GMO soy so that's a factor also. Controversial:
---------------------
Breast Cancer
A 2006 commentary reviewed the relationship with soy and breast cancer. They stated that soy may decrease the risk of breast cancer, but cautioned that the impact of isoflavones on breast tissue needs to be evaluated at the cellular level in women at high risk for breast cancer.[131] A high consumption of omega-6 polyunsaturated fatty acids, which are found in most types of vegetable oil including soybean oil, may increase the likelihood that postmenopausal women will develop breast cancer.[132] Another analysis suggests an inverse association between total polyunsaturated fatty acids and breast cancer risk.[133] A 2011 analysis of the literature said: "Our study suggests soy isoflavones intake is associated with a significant reduced risk of breast cancer incidence in Asian populations, but not in Western populations."[134]
In a recent (August 2011) trial the daily administration of tablets containing 200 mg of soy isoflavones for 2 years did not prevent bone loss or menopausal symptoms.[135][136]
Brain
Though there is some evidence that estrogen can help protect and repair the brain after injury in rats,[141] there is also evidence that phytoestrogens may be harmful for the recovery of rats in other situations[142] that have sustained brain injury.
Similarly, epidemiological evidence of humans eating soya products is currently divided: a study of Japanese men between 1965 and 1999 demonstrated a positive correlation between brain atrophy and consumption of tofu meals,[143] and a study on elderly Indonesian men and women found that high tofu intake was associated with poorer memory, but the consumption of tempeh was associated with better memory.[109]
Pancreatic Cancer
Though raw soy flour is known to cause pancreatic cancer in rats[145] the cooked flour has not been found carcinogenic.[146][147] Whether soy might promote pancreatic cancer in humans is unknown because studies have not yet attempted to single out soy intake and the incidence of pancreatic cancer in humans, and the amount of soy fed to the rats is proportionately far larger than what humans would normally consume. However, the soy isoflavone genistein has been suggested as a chemopreventive agent against pancreatic cancer, by interfering with the chemical pathways that promote the creation and growth of tumors.[148]

Soy fiber (& soy milk) is one of the most controversial food substances out there...

Declaring something to be "controversial" is an attempt to invent controversy

Maybe that's what the gluten free is all about? The crap that goes into breads is making many of us

Very interesting. I would say something is going on with the bread and cereals, no doubt.

Steal and coal were very dirty industries. My ancestors worked the land, taught, sewed clothing
