P.4 bottom paragraph: "To obtain the mean American diet, researchers use actual per capita food supply data summarized in the Food Balance Sheets for 2002 (primary source). Those Balance Sheets report a total gross caloric consumption of 3774 Kcal/person/day), of which 1047 Kcal (BNID 104636), or 27.7%, are animal-based." |

P.3 2nd paragraph: "Accounting for food exports, in 2002 the U.S. food production system produced 3774 Kcal/person/day or 1.4 × 10^15 BTU/yr nationwide (primary source). (The difference between 3774 Kcal/person/day and the needed average ~2100 Kcal person/day is due to overeating and food discarded after being fully processed and distributed.)" Value derived using 3774kcal in the equation 1 Calorie=~4.2 Joule. See also energy needed for survival 4000kJ/person/day (BNID 100728), Energy needed for human at "white collar" work 8000kJ (BNID 100729). |
