Nutrient Analysis of Raw United States Beef Offal Items.

Nutrient composition of beef offal was evaluated to expand availability of nutrient data for the following beef items: beef heart, liver, kidney, tongue, honeycomb tripe, oxtail, marrow bones, testicles, and blood. These items are consumed both domestically and internationally, with significant regional variations that can be contributed to unique cultural meals and dietary patterns. Standardized procedures were used to dissect and homogenize beef offal samples. Nutrient analysis occurred at United States Department of Agriculture Agricultural Research Service-approved laboratories using validated methods and standards. Each of the offal items in the study qualified for at least one "Good Source" or "Excellent Source" nutrient labeling claim as defined by the United States Food and Drug Administration, based on composition of the separable lean component. This study provides analytically derived nutrient information for U.S. beef offal items. The results reflect that these products could be beneficial in providing essential nutrients as a component of a healthy diet.
