Some clever fellow decided to shave a nickel by padding their shredded parmesan with sawdust and now the other brands of parmesan have "No cellulose!" on the label as if that is a selling point. Which it is, now, alas.

Reminds me of the Adulteration of Food and Drugs Act passed in Britain in 1860 to try to stop bakers from adulterating bread in all kind of unhealthy ways..
In the best case, you might have had chalk added to whiten your bread. In worse cases, alum..
A similar law in the US exists to prevent non-food being put inside food. It's why kinder surprise is banned in the US. It's not because Americans are "too stupid" to avoid choking, it's because the rule already existed and there's not really a good justification to change it for the sake of a foreign candy company.
