Problems with Soy

Did you see the documentary Food Inc?  I did.  It changed many of my thoughts and opinions of food in America and the FDA.  If you have an extra ten minutes click on the link below to watch the video and see how we as Americans are forced to consume genetically modified soy beans.

In an article on LIVESTRONG.COM, Owen Bond writes that "most soy products and powders are made with soy protein isolate, or SPI, which is a protein-rich powder extracted from the waste product of soy oil manufacturing."  According to the article there are a few components of soy products that may have adverse affects on our bodies.

Phytic Acid

This component can inhibit the body's ability to absorb essential minerals, such as calcium, magnesium, copper, iron and zinc.  Consuming too much soy protein powder could lead to mineral deficiency.

Trypsin Inhibitors

This is a type of enzyme inhibitor that makes it difficult for the body to digest protein.  This in turn creates stress in the gastric system and deficiencies in our bodies use of amino acids.  It is possible to remove some of the Trypsin Inhibitors but the high temperatures used in this process may leave the proteins inadequate for human digestion.

Phytoestrogens

This component is a type of plant estrogen.  Consuming phytoestrogens and interfere with the hormone producing endocrine glands.  The potential ramifications of this interaction are infertitility and hypothyroidism.  It can even promote breast cancer.  In men it can reduce testosterone.

Aluminum

YES!  Aluminum!  The addition of Aluminum happens during the production of SPI.  The soy products are involved in acid washing in aluminum tanks.  During this process aluminum particals attach to the final product.  The affects of aluminum include damage to nerve tissue and may be related to Alzheimer's.
