Buckwheat likely sounds scary if you're on the gluten-free diet. But despite its name, buckwheat is not wheat. It’s gluten-free, and it’s safe for people with celiac disease and non-celiac gluten sensitivity.

In fact, buckwheat and wheat come from completely different botanical families. Buckwheat seeds are technically the fruit of a plant called Fagopyrum esculentum; while wheat berries are the ripe seeds from plants in the genus Triticum.

Safe Sources of Buckwheat

There are several different brands of buckwheat and kasha on the market. Not all are considered gluten-free (although buckwheat is naturally gluten-free, it can be subject to significant gluten cross-contamination while it's being grown and processed).

However, these three brands should be safe for those of us who are gluten-free:

  • Arrowhead Mills buckwheat groats and flour. These are certified gluten-free, meaning they should contain less than 10 parts per million of gluten (less is better). Arrowhead Mills also offers a buckwheat-based gluten-free cereal: Organic Maple Buckwheat Flakes.
  • Birkett Mills/Pocono buckwheat products. Birkett Mills offers a variety of buckwheat products ranging from whole groats to pancake mix and cream of buckwheat cereal. Although the company also processes wheat, its buckwheat is processed on dedicated equipment. It's also cleaned prior to processing to remove any stray gluten grains. Birkett Mills says it tests to ensure buckwheat products contain less than 20 parts per million of gluten (the legal limit).
  • Bob's Red Mill buckwheat groats and organic whole-grain kasha. You'll find these products online and in stores that carry a full array of Bob's gluten-free products. The company processes its gluten-free products in a separate facility (note that the facility also processes gluten-free oats), and tests the products to ensure they contain less than 20 parts per million of gluten. Don't purchase Bob's Red Mill buckwheat flour, as it's not considered gluten-free.

    Why Eat Buckwheat?

    Although buckwheat is not a grain, it is sometimes referred to as a "pseudocereal." For processing into food, buckwheat seeds must first be dehulled. The remaining seed material, called groats, can be ground into flour. Roasted buckwheat groats are known as kasha. 

    There are plenty of good reasons to eat buckwheat. It's high in protein and B vitamins and rich in phosphorus, potassium, iron, calcium, and lysine.

    Buckwheat is also a good source of fiber: a one-cup serving of cooked buckwheat groats provides 17 grams of dietary fiber (you should get 25 to 35 grams of fiber every day). It also contains 22 grams of protein. 

    There's even some evidence that buckwheat can help to lower your cholesterol levels, just as oatmeal seems to do. This may be something to remember if you also react to oats (some people who can't have gluten also need to avoid oats), or even if you just want an alternative to your daily bowl of oatmeal.
