Object of class data.frame containing a modified FPED data set for specified year and day. FPED proper contains several more variables than are necessary for computing HEI scores. The data set returned by this function has been trimmed down to contain (in addition to an NHANES unique sequence identifier for each participant, age, and dietary recall status) only the columns of data needed for HEI score calculation, specifically:

T_F_CITMLB: Intact fruits (whole or cut) of citrus, melons, and berries (cup eq.)
T_PF_EGGS: Eggs (chicken, duck, goose, quail) and egg substitutes (oz. eq.)
T_F_OTHER: Intact fruits (whole or cut); excluding citrus, melons, and berries (cup eq.)
T_PF_MPS_TOTAL: Total of meat, poultry, seafood, organ meat, and cured meat (oz. eq.)
T_PF_SOY: Soy products, excluding calcium fortified soy milk (soymilk) and mature soybeans (oz. eq.)
T_PF_SEAFD_HI: Seafood (finfish, shellfish, and other seafood) high in n-3 fatty acids (oz. eq.)
T_PF_SEAFD_LOW: Seafood (finfish, shellfish, and other seafood) low in n-3 fatty acids (oz. eq.)
T_PF_NUTSDS: Peanuts, tree nuts, and seeds; excludes coconut (oz. eq.)
T_SOLID_FATS: Fats naturally present in meat, poultry, eggs, and dairy (lard, tallow, and butter); hydrogenated or partially hydrogenated oils; shortening; palm, palm kernel and coconut oils; fat naturally present in coconut meat and cocoa butter; and 50% of fat present in stick and tub margarines and margarine spreads (grams)

T_G_WHOLE: Grains defined as whole grains and contain the entire grain kernel - the bran, germ, and endosperm (oz. eq.)
T_D_TOTAL: Total milk, yogurt, cheese, and whey. For some foods, the total dairy values could be higher than the sum of D_MILK, D_YOGURT, and D_CHEESE because miscellaneous dairy component composed of whey is not included in FPED as a separate variable. (cup eq.)
T_G_REFINED: Refined grains that do not contain all of the components of the entire grain kernel (oz. eq.)
