Fuel ethanol mostly exists because the US grows way too much corn to actually eat and we needed something to do with it. Industrial farming overshot what we needed to sustain the population and threatened to put a lot of farmers out of business.
This is one of the hidden benefits of corn ethanol, if there is some nutrition crunch it is trivial to convert back to farming food corn unlike switchgrass ethanol. There is no equipment to change out, no supply chains to rework, you just change which type of corn you plant and send the harvest to the market instead of the refiner.
