Well, I was going to comment that everyone already knows that low-quality Parmesan (like Kraft) contains "sawdust" (listed as cellulose powder). Apparently, the HN crowd already knew this even though its not common knowledge. Are readers of HN unusually curious people? I think so. Regardless, there are much much worse things in processed foods than sawdust. It doesn't suprise me that Walmart "100% cheese" is actually 7.8% sawdust. I bet Walmart brand honey is also very impure, regardless what the label says.
