Buckwheat belongs to a group of foods commonly called pseudocereals. Pseudocereals are seeds that are consumed in the same way as cereal grains, but do not grow on grasses. Other common pseudocereals include quinoa and amaranth. Despite its name, buckwheat is not related to wheat, and is therefore gluten-free.
Buckwheat has become popular as a health food in many countries, due to its high amounts of minerals and various antioxidants. It has also been shown to provide health benefits.
Buckwheat scores low to medium on the glycemic index (3). In other words, it should not cause unhealthy spikes in blood sugar levels.
