| "I've decided that folks are just about as happy as they make up their minds to be." - Abraham Lincoln |
| Information is provided on household measures for food items (for example, 1 cup, 1 tablespoon, 1 fruit, and 1 leg). Weights are given for edible material without refuse. The Weight file contains the gram weights and measure descriptions for each food item. This file can be used to calculate nutrient values for food portions from the values provided per 100 g of food.
The formula used to calculate the nutrient content per household measure is: N = (V * W)/100 The Gram Weight file can be used to produce reports showing the household measure and nutrient values calculated for that portion. The weights were derived from published sources, industry files, studies conducted by USDA (Adams 1975, Fulton et al. 1977), and the weights and measures used in USDA's Continuing Survey of Food Intakes by Individuals (USDA 1995). Although special efforts were made to provide representative values, weights and measures obtained from different sources vary considerably for some foods. Starting with this release we have combined the Gram Weight File and the Measure Description File to make this information easier to use. |
