In Reply: Dr Dubost questions the methodology of collecting and analyzing food samples used in our study evaluating the accuracy of stated energy contents of randomly selected foods purchased in randomly selected restaurants in 3 regions of the United States. Dubost notes that the USDA has collected foods, including a small number of foods from restaurants, for composition analysis using a protocol1 that shares similarities with the protocol the Food and Drug Administration uses for testing the nutrient contents of commercial packaged food items and suggests that our protocol is less valid because we took fewer replicates from fewer locations. We disagree.
