Buckwheat is a gluten-free starchy pseudocereal whose triangular seeds (groats) are cooked as a grain or milled into flour. Despite its name, it is botanically unrelated to wheat and belongs to the Polygonaceae knotweed family.
History & Origins
Buckwheat was domesticated in southwestern China, particularly the Yunnan region, between 6,000 and 8,000 years ago, where it was cultivated alongside millet by early farming cultures. It spread westward along Silk Road and steppe trade routes through Central Asia, reaching the Balkans and Eastern Europe by the medieval period, where it became a dietary staple in Slavic countries (Russian kasha, Polish kasza) and in the Brittany region of France. Despite being later displaced by true cereals in many regions, buckwheat has experienced a global revival since the late twentieth century due to its gluten-free status and dense micronutrient profile.
