Study Notes
- Food availability refers to the annual estimates of the amount of food available for consumption in the US food distribution system.
- This represents the amount of food that disappears through the domestic food production distribution system.
- This system spans from farms to supermarkets, restaurants, and fast-food outlets.
- Waste (retail, home, restaurant)
- Food balance sheet approach: Available Commodity Supply - Measurable Nonfood Use = Total annual amount of food available for consumption (Food Availability)
- Available Commodity Supply = Production + Imports + Beginning Stocks
- Measurable Nonfood Use = Farm Inputs + Exports Ending Stocks, etc.
- Per capita availability is calculated by dividing the total amount of food available by the total number of people in the US population.
- Data collection started to track surpluses, reasons include:
- World War 1
- 1930s depression, droughts.
- Data was compiled as far back as 1909 (first reliable), annually since then for 250 product since 1949.
- Food availability data is used to evaluate:
- Historical trends in consumption.
- Changes in response to technology.
- Whether enrichment and fortification is working.
- If industry is responding to public health concerns.
- Federal dietary guidelines.
- Limitations of food availability data:
- It cannot directly measure individual, household, or regional consumption.
- Overestimates food consumption.
- Strengths of food availability data:
- It's the only consumption data available from the early 1900s onward.
- Overall patterns are pretty reliable.
- Good for international comparisons.
- It is useful for ecological studies of diet and disease.
- Not subject to bias from individual data collection.
