Regulation
Regulatory status
No bans or restrictions are recorded for this ingredient in the jurisdictions clearlabel tracks (US, EU, UK, Canada, Japan, Australia/NZ, Brazil).
Explainer
In plain language
Cellulose fillers are forms of plant fiber, usually made from wood pulp or cotton, that are refined into fine powders and gels for food use. Microcrystalline cellulose and powdered cellulose are used to prevent caking, add bulk, replace fat, or keep shredded cheese from clumping. They pass through the body largely undigested and add no calories or nutrition.
Assessment
Why it is flagged
Cellulose is a well-established food additive that the FDA and EFSA authorize, and EFSA's 2018 re-evaluation found no safety concern at reported intakes. It draws attention mainly because it is derived from wood pulp and is used as a cheap bulking agent, which some people see as a marker of heavily processed or diluted products. It is essentially insoluble fiber, and there is no strong evidence of harm at dietary levels. Clear Label flags it at low severity as a processing marker rather than a health warning. Some people simply prefer to know when a product is being extended with added filler.

Practical
Reading the label
Look for microcrystalline cellulose, powdered cellulose, cellulose powder, cellulose gel, or E460. On shredded cheese it is the anti-caking agent that keeps strands separate.
Alternatives
If you want to avoid it
Some people who want to avoid added filler buy block cheese and grate it themselves, or choose products with shorter ingredient lists. Whole foods generally contain their fiber naturally rather than as an added powder.
FAQ
Common questions
Is cellulose really made from wood?
Food-grade cellulose is typically refined from wood pulp or cotton into a purified fiber. It is chemically the same structural fiber found in plants you already eat.
Is added cellulose bad for you?
It is essentially insoluble fiber that passes through undigested, and regulators authorize it with no safety concern at normal intakes. There is no strong evidence of harm at dietary levels.
Why is it in shredded cheese?
Powdered cellulose coats the strands to absorb moisture and stop them from clumping together in the bag. Grating your own from a block avoids it if you prefer.
