QuoteDespite its name, buckwheat is not wheat. It's gluten-free... Buckwheat and wheat are from completely different botanical families. Buckwheat seeds are technically the fruit of a plant called Fagopyrum esculentum.

QuoteDespite the name, buckwheat is not related to wheat, as it is not a grass. Instead, buckwheat is related to sorrel, knotweed, and rhubarb.
