1940s

U.S. was importing 40 percent of its fats and oils when supplies were cut off by World War II. Soybean producers doubled production and processors built plants to produce the oil. But the end of the war brought surpluses. The US and United Nations were shipping soy flour to Europe and Asia, but soybeans were not part of the government food aid plans.

ASA launched legislative battles to remove barriers restricting the sale of margarine. Government efforts to reduce soybean production and rigidly restrict exports were opposed.
