Value Units Notes
* Average American ARS & CDC 2010 What We Eat In America US: All (2000s) 93440 grams/person/yr
* Average Earthling FAO 1997- Carbohydrates in human nutrition Global: All (1980-1997) 109009.531 grams/person/yr This value represents the combined at home and away from home carbohydrate consumption of average earthlings.
* Average New Yorker USDA 1999- DATA TABLES: Food and Nutrient Intakes by Individuals in the United States, by Region, 1994-96 Northeast, USA: All (1994-1996) 49600.288 grams/person/yr information from USDA (1999) was compared against figures in Bureau of Labor Statistics (2006) (ID 105)
* Eco-conscious Davey et al. 2002- EPIC: Oxford : lifestyle characteristics and nutrient intakes in a cohort of 33 883 meat-eaters and 31 546 non meat-eaters in the UK global: household () 49706.18667 grams/person/yr
* Lenape Person Cordain 2000- Plant-animal subsistence ratios and macronutrient energy estimations in worldwide hunter-gatherer diets Global: Temperate forest, mostly mountainous (hunter-gatherer ecosystems) () 45625 grams/person/yr In Cordain et. al., for hunter-gatherer societies in Temperate forests, dependence on gathered plant foods is 36-45%, dependence on hunted animal foods is 16-25%, and dependence on fished animal foods is 36-45% (Table 2). Therefore, two consumption rates (g/year) were generated, one using a 45:55 plant/animal diet ratio and the other using a 35:65 plant/animal diet ratio. We assumed 15% animal fat for animal’s body composition. For a 45:55 plant/animal diet ratio, percent of energy per day from protein is 26 %, from carbohydrates is 28%, and from fat is 46%. For a 35:65 plant/animal diet ratio, percent of energy per day from protein is 28%, from carbohydrates is 22%, and from fat is 50% (Table 4). We assumed consumption of 2000 calories per day. In order to calculate the daily consumption rate in grams for protein, carbohydrates and fat for the two different ratios of plant/animal diet, we multiplied calories per day by percent of Energy/day and divided that amount by energy yield (4 kcal/g for protein, 4 kcal/g for carbohydrates, and 9 kcal/g for fat). These amounts were then each multiplied by 365 days/year. We then took the average of the two ratio’s protein, carbohydrate, and fat consumption rates. In order to receive our final values, we split this calculation in half between at home and away from home consumption.
