> If I remember correctly, Great Value Parmesan cheese was rated the worst (highest) level of wood pulp additives when tested vs other major brands.

I buy that brand too and recommend it. The label clearly lists cellulose among the ingredients and it has a legitimate function as a decaking agent. At 7.8%, it did not have the highest cellulose level in that study, though it was close. I've bought grated parmesan with low levels of cellulose, and some of it's more clumpy. However, it seems the 4% brands have the right mix. WalMart's doubling that does seem to be working as a cheap filler. The cheese in it is actually parmesan though. Much more interesting in that study though was that some brands such as Market Pantry, Always Save, and Best Choice all contained absolutely no parmesan cheese at all.

Buying a brick of hard parmesan and grating it oneself is by far the best way to go, but cheap bottled stuff that isn't too bad is more convenient for kids to work with.
