The author misses the point. The problem isn't the corn but rather the quantity of corn that's fed to cows. There weren't antibiotics to give cows to deal with the side effects of too much corn so they didn't give it to them in the quantities they do today.<p>I'm fine with giving cows some corn because well it does taste better but their feed really shouldn't contain so much corn. Most of the small ranchers I know give their cows some corn but not a huge amount or anything.
