Nutrition Guideline Project

Synopsis of the Process used for Guideline Development:



GMDI is collaborating with the Southeast Regional Genetics Network in an HRSA-funded project to develop nutrition guidelines for metabolic disorders. Each guideline has been developed using a rigorous process that includes analysis of published and gray literature, surveys of practitioners and a nominal group of expert providers, researchers and consumers. The process is further described here.
