Although there has been some controversy in the media over the consumption of soy, I do not know of any scientific studies showing that eating soy-containing foods is harmful. My view is that consuming small amounts of soy in the diet can be beneficial. However, I would advise against taking phytoestrogens such as soy as supplements as we do not know enough about the effects of taking these compounds in high doses. Also, I caution against eating processed soy products and soy additives in many foods, but instead encourage the use of traditional soy foods such as tofu, edamame, tempeh, miso, and soy sauce. Make sure they are organic and non-GMO.
