How much corn is being used for ethanol versus food products?
Corn is a commodity and commodity prices are influenced by market speculation. Corn prices rose in 2007 as investors speculated on its demand. There was no corn shortage. Remember, ethanol is produced from only the starch component of corn; 100% of the protein is retained and returned to the “food chain” as co-products such as high-value livestock feed. Most field corn is fed directly to livestock and is never intended for human consumption.
