Thanksfor the heads up, Ariel.
Very good article in the Mail and mentions what AmberLeaf said about thyroid
Meanwhile, there have been suggestions that, far from being protective, eating too much soya protein can be harmful because of its hormonal effect.
In 2003, the UK government?s Committee on Toxicity identified three groups where evidence suggested there might be a potential risk from consuming large amounts of soya: babies fed on soya-based formula, people with an under-active thyroid and women diagnosed with breast cancer.
Soya beans contain naturally occurring toxins. These include phytic acid, which reduces our ability to absorb essential minerals, such as iron and zinc, and might therefore cause mineral deficiencies, and trypsin inhibitors, which impair the body?s capacity to digest protein.
But the industrial nature of soya protein manufacture also raises concerns.
While some soya foods, such as tofu, miso, soya milk and yoghurt, are lightly processed, pure soya proteins ? the sort you might find in a veggie sausage or vegan cheese ? are commonly extracted by washing soya flour in acid in aluminium tanks.
This raises the possibility that aluminium, which is bad for the brain and nervous system, can leach into the product.
Another potential concern is the chemical solvent hexane ? a component in glue and cement ? is used to extract the oil from soya beans. It is known to poison the human nervous system.
Through repeated exposure, people can develop neurological problems similar to those experienced by solvent abusers.
The soya industry claims only trace residues of hexane find their way into the finished product.
Processing also frees up glutamic acid from the soya, a substance that can trigger allergic reactions.
Soya is one of the eight most common food allergens, according to the U.S. Food and Drug Administration.
A further issue with many soya products is not the soya itself, but what is added to it.
As soya protein is pale, odourless and almost taste-free, many manufacturers rely on sweeteners, artificial flavourings, salt and colourings to make their products more appealing.
