Some experts advise that consuming too much phytoestrogens may negatively effect your baby’s development. Studies have confirmed that high soy intake can cause an increase in defects with animals. Soy also contains phytic acid which is a natural substance which binds to minerals such as niacin, iron, magnesium and zinc.

Regular use of soy throughout a day may result in deficiencies in these important minerals.
