Worth knowing
Because cellulose cannot be digested by humans, it is a popular ingredient in "zero calorie" or low-carb diet foods to provide bulk.
Conclusion
Cross-linked CMC is a limited concern that is relevant mainly if you regularly consume processed diet products using modified cellulose. It passes through the digestive tract as inert insoluble fibre and is confirmed safe by EFSA at authorised food levels. For standard consumers, cross-linked CMC is a minor detail on the label.
