Healthy Eating Index Clinical Trial
Official title:
Red and Processed Meat Effects on the Metabolome and Microbiome
This controlled feeding trial will identify biomarkers in the metabolome and microbiome that may differ when consuming a healthy diet with or without red and processed meat.
This is a randomized cross-over feeding trial to test whether red and processed meat consumption, in the context of a controlled diet based on HEI-2015, will cause shifts in the metabolome and the microbiome compared to a controlled HEI-2015 diet with no red or processed meat. Twenty healthy adult volunteers will consume two diets in random order: 1) Diet A is based on the Healthy Eating Index-2015 (HEI-2015) and includes no red or processed meat; 2) Diet B is based on the Healthy Eating Index-2015 and includes red and processed meat (HEI-2015-M) as some of the protein sources. Both diet periods last 21 days and an approximately 21-day washout period occurs between diets. ;
