The Full Answer
Lo mein is made from wheat-flour egg noodles and tossed in a sauce built on soy sauce (and often oyster sauce), so it contains gluten from multiple sources and is not safe for people with celiac disease.
Like other Chinese noodle dishes, it is also cooked in shared woks, so cross-contamination is a concern. Standard lo mein has no gluten-free version because the wheat noodle is central to the dish.
To enjoy something similar, use rice noodles or a certified gluten-free noodle with a tamari-based sauce and a clean cooking surface; many Chinese restaurants can prepare a gluten-free stir-fry on request.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces — such as shared cutting boards, toasters, fryers, or utensils — rendering otherwise safe food dangerous for people with celiac disease.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten — stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
