Soy does contain a protease inhibitor, named 'Bowman-Birk Soy Protease Inhibitor' or BBI (1)
Although it has been isolated in soy milk (although you have to drink about 60oz of soy milk 2-3 times daily), BBI is destroyed in cooked soy products, which are devoid of protease inhibitor activity. (2)
Significant effects from protease inhibition can only be produced in rats by feeding them astronomically large amounts of raw soy flour. (4)
The classical Bowman-Birk inhibitor from soya retards strongly the hydrolysis of elastin catalyzed by leukocyte elastase, cathepsin G and the mixture of both. (5)
Now, what the 'anti-soy boys' don't either understand or will not tell you:
1. BBI protease inhibitor from soy has well recognized anti-carcinogenic properties (3).
2. BBI protease inhibitor from soy is a signifiant inhibitor of Human Leucocyte Elastase (HLE) and enzyme that dissolves the protein elastin and also degrades and inactivates a number of plasma proteins. Elastase probably plays a physiological function in neutrophil migration, phagocytosis and tissue remodeling. HLE apparently plays a pathological role in pulmonary emphysema, Rheumatoid Arthritis , endometriosis, infections and inflammation. (7)
Thus type A's on a soy based diet can look foward to having lower levels of inflammation, allergy, cancer and infection by virtue of this 'poison' in soy!
I find it interesting that many of the soy-bashers recommend soups and other gellatin-based products, which are rich in the polysaccharide chondroitin sulphate. Just like soy protease inhibitor, chondroitin is also a 'protease inhibitor' with regard to HLE.(6) So what's the difference?

I've been reading about the potential dangers of soy, what's the story?
Soy is a good food if you are type A. By this it is meant that soy will not make you FEEL good if you are type A. Some of the good things soy is doing may, in fact, make you feel not so great after you eat it, but it is good for you nonetheless. Here it is the effect of soy lectin on the blood and immune system. These uncomfortable reactions are usually temporary. Making sense of the recent controversial articles about soy, phytates, aromatase and minerals:
Phytates are in soy.
Humans secrete phytase (and occasionally consume it), which is an enzyme responsible for the breakdown of phytic acid. Some animals, namely rats, have close to none of this enzyme. This means that in humans it won't bind the minerals no where near as much as rats. Phytates are converted to inositol, and phosphate in the human body which has other beneficial effects. Most "tests" are done on rats [and are not applicable to humans]. Phytic acid protects against the two biggest cancer killers in men and women, namely breast, and prostatic cancer.
The relatively low methionine levels in some phytochemicals such as soy, limit the synthesis of polyamines necessary for tumor growth. Methionine is problematic for type A's in other areas as well: it is linked to elevated levels of homocysteine, a significant risk factor for artery disease.
Genistein and daidzein, the major phytoestrogens in soy are themselves 'aromatase inhibitors. This is true of many isoflavones. Aromatase is an enzyme which converts androgens to estrogens. Aromatase is located in estrogen-producing cells including ovaries, placenta, testicular Sertoli and Leydig cells, adipose, and brain tissues. Aromatase inhibitors are increasingly the drug of choice for managing metastatic breast cancers which have retained estrogen sensitivity.
High levels of the enzyme aromatase stimulate estrogen sensitive cancers. The isoflavones (phytoestrogens) in soy inhibit aromatase. Another potential problem with soy is that of genetic manipulation. An ever increasing amount of soy planted in the United States has been genetically altered.
In addition, many commercial varieties of soy have been manipulated to increase the fat and protein content of the bean. The long term results of these manipulations are unknown, and wait to be seen. In general, organic soy has not been altered or manipulated, and products made from organic soy should be the soy of choice.

This is a reply to # 10,586I am not a Soy Basher, but the hard way, I have discovered that SOY and its Products have a very negative effect on my Type A body.
Can anyone address this?- Re: Stuff you should know about soy,... hokouri

This is a reply to # 10,586My wife has serious CFS/FM, endo, IBS, problems. Our MD recommended a food intolerance test to screen out foods her body reacted badly too.
Top of the list of bad boys was soy.
So, even though she is type A, she now avoids this like the plague. Also on the list of no-no's was garlic! Go figure...........
P.S. She's now feeling better.- Re: No axe to grind, but..... Buckland

This is a reply to # 10,597I have just been diagnosed with Angina as a result of having too much Cholesterol in my system. Since then I have cut out all the bad habits that I have had like cheese, whole milk, butter and anything else that has any amount of Cholesterol in it. One of the things I switched to is a soy product for my cereal instead of milk. Have I just shot myself in the foot?

This is a reply to # 10,650According to Dr. Dadamo, no. But many of us As do have questions about soy - particularly in unfermented forms. There is always rice milk or almond milk.

This is a reply to # 10,651Thanks Judy G, I'll try those on for size. I am thinking also about trying the liver cleanse - do you have any comments on that?
Thanks,

What type of food intolerance test did you do- was it a muscle response test?
What happens when she eats soy and garlic?
It is of utmost importance to judge things by how they make YOUR body feel.
I have serious skepticism when it comes to MD's, I would go to an ND and see what they say because blood typing is very reliable for most people, and if she is avoiding soy and garlic that's probably not good.
