¹SNAP reference family of 4 consists of 2 adults (a male aged 20–50 y and a female aged 20–50 y) and 2 children (a child aged 9–11 y and a child aged 6–8 y) and the results presented in this paper are the summation of those 4 age-gender groups.

²SI unit conversion: 1 kcal = 4.184 kJ.

³The targets for the TFP and TFP_FAFH models were derived from the Dietary Guidelines for Americans 2005 (28) and the DRI (29). Numbers presented in this table are the summation of the 4 age-gender groups. We use median weight/height levels of each 1 of the 4 age-gender groups and a low active physical activity level (30) to define the energy level for each age-gender groups.

⁴Current refers to the current observed low-income family food consumption pattern.
