See Which Pre-Grated Parmesan Cheese Contains a Wood Pulp Additive Filler

When customers buy parmesan cheese they expect it to be 100 percent real cheese. But an Inside Edition investigation has found that is not always the case. Some companies use a filler made from wood pulp in their cheese called cellulose to keep the cheese from caking. The FDA says there should be no more than 2 percent. A sample from Pizza Hut had 4.9 percent cellulose and one at Domino's came in at 5.4 percent. A packet of Colonna brand grated cheese had 21.6 percent cellulose. #InsideEdition
