Feeding Children with Feed Corn?

I know it's a pointless exercise to prove the Family Research Council wrong, but in an email that went out to their members today, they said:

The U.N. estimates that the amount of corn it takes to fill a 50-liter car tank with ethanol is enough to feed a child for an entire year.

I'm having a hard time finding the report online and am not sure exactly what the original UN report said (probably something along the lines of the resources used to grow corn for a take of gas could be used to grow food for a child for a year), but it's certain that that corn used to make ethanol is NOT the same corn that you would feed a child. Furthermore, a lot of liberals aren't such big fans of ethanol anyway. Even the most moderate tend to view biofuels like ethanol as a temporary solution and not a permanent one.
