Final answer:
Breaded chicken generally contains gluten due to the wheat flour used for breading. It's crucial for those with celiac disease to opt for gluten-free options to prevent digestive system damage.
Step-by-step explanation:
All breaded chicken typically contains gluten because the breading is usually made from wheat flour which is a known source of gluten. The allergen information provided indicates that products may contain egg and mustard and are processed in a facility that also processes products with gluten, milk, soya, celery, sulphites, and their derivatives. Therefore, anyone with celiac disease should avoid breaded chicken unless it is specifically labeled as gluten-free. For those with celiac disease, consuming gluten, even in trace amounts, can damage the digestive system, as gluten is a protein found in wheat that causes an adverse reaction in these individuals.
