“Grain crops, such as wheat and oats, also became more plentiful after World War II, often running to surplus. It isn’t difficult to draw a line between grain surplus and the federal government’s emphasis on grains in the American diet. When the United States Department of Agriculture (USDA) started recommending dietary standards in 1946, grains got the lion’s share of daily recommended servings and dairy enjoyed its status as an entire food group. Nuts were nowhere to be found.”
