A greater percentage of field corn is used as animal feed vs. the percentage used for human consumption, true. But your original comments indicated that "we eat sweet corn and white corn".
My comments pointed out that we don't just eat sweet corn and white corn, as most of the corn products we consume, except for fresh, canned and frozen, are derived from field (dent) corn.
"Do you know the actual percent of yellow used for human food vs. animal?"
Yes, I have the USDA statistics for US Corn Production & Use. In 2007, the US produced a little over 13 billion bushels of field corn. About 6.1 billion bushels of that went to feed livestock. 3 billion bushels went to ethanol production and a portion of that is livestock feed after the ethanol is produced. 2.45 billion bushels were exported and I do not have figures for specific use on those bushels. Just under 1 billion bushels were used to produce corn starch, corn sweeteners and corn oil, with the residue being livestock feed. 328 million bushels produced corn flour, meal, grits, masa and corn beverage, with the residue being used for livestock feed.
Looks like we have answered each other and reached consensus.
As easy as that was, I wish people would go to the trouble to look it up before complaining about how we are burning up our food supply.
