The reason why you need to stop buying shredded cheese is because most shredded cheese contains cellulose.
Cellulose is a cheap filler in shredded cheese that is made from cotton lint or wood pulp.
The cellulose in some shredded cheese is used to prevent the shredded cheese from clumping.
However the cellulose in the shredded cheese can also create a barrier to flavor, affect the flavor and texture of the shredded cheese, make the shredded cheese drier when it's served cold and cause bloating, diarrhea and gas.
In severe cases the cellulose in the shredded cheese can cause blockage in the intestines.
The blockage in the intestines can also occur when you eat too much of the shredded cheese and even cause constipation.
Shredded cheese can also contain other types of additives like potato starch, which can affect the texture and the flavor of the shredded cheese.
Shredding cheese blocks at home to make fresh shredded cheese at home is a healthier option to the store bought shredded cheese.
Freshly shredding cheese at home is the healthier option and can also taste better than the store bought shredded cheese.
Shredding your own cheese at home can also be cheaper than buy prepackaged shredded cheese.
