Could the Department of Agriculture go back to its role before 1964?

This department was started in 1789 by George Washington to help out farmers.  Then in the early 1900's a progressive president Theodore Roosevelt had this agency start inspecting food processing plants to make sure the food is what is on the label.  In 1946 Congress directed this agency to be the authority of nutrition in relation to the National School Lunch Act and help developed the food pyramid in the 1950's.  In the Great Society this agency was in charge of distributing food stamps.  Maybe we can get this agency back to its original purpose which is to help out the nation farmers that is it.
