Abstract
This review is a synopsis from a recent symposium entitled "Update on Nutrition Research Methodologies" presented at the American College of Nutrition's Annual Meeting in Orlando, in October 2009. The speakers provided an overview of new handheld and Web-based dietary assessment tools and their application to clinical and epidemiologic studies, identified key features and attributes for comparative effectiveness studies in nutrition, identified how to critique the literature on nutrition and dietary supplements and apply the principles of evidence-based reviews to their research, and examined the level of evidence needed to support the development of public health policy for nutrients and dietary supplements
