Technical Abstract: Objective: To update the common household measures, gram weights and percent refuse for raw fruit in the USDA National Nutrient Database for Standard Reference (SR). Methods and Materials: For the National Food and Nutrient Analysis Program (NFNAP) selected raw fruit were picked up in 12 locations across the U.S. at two different times of the year. In addition to analyzing these samples for nutrient content, individual pieces of fruit were weighed and measured before and after the removal of refuse, such as skin, seeds, and/or stems. These data, in addition to information from the Agricultural Marketing Service, Food and Drug Administration, food industry organizations, and Price Look-Up (PLU) sizes, were used to reassess the weights and % refuse for selected raw fruit in SR. Results: Discrepancies arose among the various sources and methods for determining the weights and sizes for many fruits and had to be resolved. Reassessment of weights for a few fruits, including apples and peaches resulted in significant changes in gram weights. For example, the weight of small and medium peaches increased by more than 50%. Significance: Weights and measures and refuse are important for dietitians, researchers, educators and consumers to help estimate the nutrient content in a specified portion of food. For foods that are frequently consumed a modest change in the gram weight for one serving of fruit can have significant impact on food consumption surveys and other research studies.
