Soy

Soy has become popular lately due to some reported benefits but there are some problems associated with its use.  The soy we consume in this country is different then the soy in Asia.  In asia the soy is naturally fermented at low
temperature. In the west it is produced at a high temperature. The high temperature breaks down some of good compounds that provide some benefit.  Also, the average consumption of soy is about a teaspoon per day in Asia, many americans are consuming much more than that.  This can lead to problems.   Soy has high levels of phytic acid.  Phytic acid reduces the assimilation of calcium, magnesium, iron, copper and zinc.  High phytic diets have been shown to cause growth problems in children too.  Soy phytoestrogens disrupt endocrine gland function and have the potential to cause infertility and to promote breast cancer. Soy foods also increase to body's requirement for Vitamin D and B12. Soy phytoestrogens are potent antithyroid agents that cause hypothyroidism and may cause thyroid cancer. In infants, consumption of soy formula has been linked to autoimmune thyroid disease. Go to
