Grains: Trends in U.S. Per Capita Availability and Intake
Jean Buzby and Judy Putnam Economic Research Service
U.S. Per Capita Food Consumption Data
First published in December 1941
Annual data extends back to 1909
Only source of time series data on food and nutrient availability in the country
Major component of the Nation’s nutrition monitoring system
U.S. Per Capita Food Consumption Data Major Uses
Analyze commodity markets
Study relationships between …Income, prices, and consumptionDiet and health
Evaluate effects of technology and marketing changes over time
Develop and manage public policies, regulations, and programs
Cross-country comparisons (fao.org)
Food Consumption As Reported by Producers and Consumers: Improving What We Know
Per capita food availability (aka food supply) dataComes from producers and processors
Overstates food intake
New ways of adjusting for losses
Individual food intake dataComes from a large sample of consumers
Understates food intake
New interviewing techniques to minimize underreporting
Webster Definitions for “Consumption”
In economics …
the using up of goods and services: opposed to production
the amount used up
The act or process of consuming
To eat or drink especially in great quantity <consumed several kegs of beer>
Estimating U.S. Food Consumption
Equals
Production + Beginning Inventories + Imports
Exports + Farm and Industrial Use + Ending Inventories
U.S. Food Consumption (Availability)
Minus
U.S. Per Capita Food Consumption Data
Food Availability Estimates, 1909-2002
Derived from food availability estimates:
Nutrient Availability Estimates, 1909-2002
Food Intake Estimates/Pyramid Servings, 1970-2002
Nutrient Availability Estimates, 1909-2000
Amounts per capita per day of food energy and 27 nutrients and food components in the U.S. food supply
Nutrients contributed from major food groups, per capita per day
Food Intake/Pyramid ServingsDerived from Food Availability Data
ERS uses aggregate food availability data, adjusts for losses, and converts the remaining supply into Food Guide Pyramid servings.
These are then compared with servings recommendations for the U.S. population.
Allows researchers to compare the amount and types of food available in the food supply with information from consumers about their actual food intake
