Abstract
This article summarizes presentations from the International Breast Cancer and Nutrition workshop held during the ASN Scientific Sessions and Annual Meeting at Experimental Biology 2014 in San Diego, CA, on 28 April 2014. An international collaboration was described among teams from low-, middle-, and high-income countries addressing environmental factors, especially diet, and epigenetic interactions that affect the risk of chronic disease. Speakers addressed opportunities and challenges involved in this type of international collaboration, assessing diet and nutritional status across a wide range of cultures, and research tools and discoveries from this group.
