🌍 Regional Safety Checker
Yes. Despite the name, buckwheat is not wheat — it is a gluten-free seed related to rhubarb. Watch buckwheat pancake mixes and soba, which often add wheat.
Buckwheat is analyzed under general rules for this region. Buckwheat is the seed of a plant related to rhubarb, not a cereal grass, and has nothing to do with wheat. The Gluten Intolerance Group says "buckwheat is not wheat but a gluten-free member of the rhubarb family", Bob's Red Mill describes its groats as "gluten free seeds from a plant related to rhubarb", and the Celiac Disease Foundation lists buckwheat groats (kasha) as naturally gluten-free.
The Full Answer
Buckwheat is the seed of a plant related to rhubarb, not a cereal grass, and has nothing to do with wheat. The Gluten Intolerance Group says "buckwheat is not wheat but a gluten-free member of the rhubarb family", Bob's Red Mill describes its groats as "gluten free seeds from a plant related to rhubarb", and the Celiac Disease Foundation lists buckwheat groats (kasha) as naturally gluten-free.
The catch is what buckwheat gets mixed with. Bob's Red Mill's own Buckwheat Pancake Mix contains whole wheat flour and vital wheat gluten. Most soba noodles are a buckwheat-and-wheat blend. Naturally gluten-free grains can also pick up gluten from cross-contact during harvesting and processing, which is why some plain buckwheat products carry a gluten-free label and others do not.
For celiac safety, buy buckwheat groats, kasha or flour labeled gluten-free, and read the ingredients on anything sold as "buckwheat" pancakes, crepes or noodles.

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.
