Soybeans play an important role in the US food supply.  For example, soybean oil accounts for over 40% of the US intake of essential fatty acids—both linoleic acid and alpha-linolenic acid—and soy protein is added for functional purposes such as moisture retention to a wide range of commonly-consumed foods.  Because of its high quality, soy protein can make important contributions to nutrition.

However, most of the interest in soyfoods over the past 30 years has focused on these foods as uniquely-rich sources of isoflavones.  Isoflavones are classified as phytoestrogens and selective estrogen receptor modulators.  These soybean constituents have been posited to reduce risk of several chronic diseases but concerns have also been raised about their safety.  This presentation will discuss the proposed health benefits of soyfoods and will address topics such as the effects of soy on male hormone status, the impact of soy on breast cancer prognosis and the effect of soy on mineral absorption and status. Emphasis will be placed on the clinical and prospective epidemiologic data.

The live version of this webinar was presented by Mark Messina, PhD, on Wednesday, August 24, 2016, at 2 pm ET. This recorded version is approved for one hour of continuing education credit. RDs should list code 175 for this activity type.
