The USDA is a big, complicated agency with many units working at apparent cross purposes. I particularly like the work of the Economic Research Service, which produces reports on many interesting aspects of the food economy. Here is a new one, for example, on trends in the availability of foods for consumption by Americans from 1970 to 2005. This is not a report on what people actually eat. “Availability for consumption” means foods produced in the United States, less exports, plus imports, divided by the total population. My favorite figures from the report: added fats and oils account for 32% of caloric availability (this does not count the fat normally present in foods), and added sugars are up 19%. Dietary recommendations suggest consuming no more than 8 teaspoons of sugars a day; 30 are available per capita. This report does not give nutrient information, but other USDA/ERS reports show that the number of calories available for consumption increased from 3,200 to 3,900 per person per day over that period. If more food is available, more of it has to be sold….
Correction: make that 4,000 calories per person per day in the latest USDA report.
