Is Buckwheat Gluten Free? Unlock the Secret!

Written by Dr. Amber Jones

Gluten-free diets have become increasingly popular, with many people eliminating gluten for health, dietary, or medical reasons. For those following a gluten-free diet, knowing what foods and ingredients are naturally gluten-free is important. One ingredient that often comes up is buckwheat - so is buckwheat gluten-free?

Buckwheat is naturally gluten-free. Unlike wheat and some other common grains, buckwheat does not contain the proteins glutenin and gliadin, which together form gluten in wheat.

So products made from pure buckwheat contain no gluten and are considered gluten-free. This makes buckwheat and buckwheat flour safe for people with celiac disease or non-celiac gluten sensitivity.

What Exactly Is Buckwheat? 

Buckwheat Food Item

Buckwheat, despite its name, is not related to wheat and does not contain gluten. Buckwheat is the seed from a fruit related to rhubarb. The triangle-shaped seeds are used to make buckwheat flour, groats, noodles, and more. Buckwheat has become popular because it is nutritious, easy to grow, and gluten-free.

As a whole grain, buckwheat delivers fiber, antioxidants, and important vitamins and minerals like manganese, magnesium, copper, and iron.

Since it is one of the few naturally gluten-free pseudocereal grains, buckwheat is a great choice for anyone following a gluten-free diet, whether due to celiac disease, non-celiac gluten sensitivity, or simply by choice.

Types of Buckwheat

There are a few different varieties of buckwheat, but the most common types used for food are common buckwheat (Fagopyrum esculentum) and tartary buckwheat (Fagopyrum tataricum).

Tartary buckwheat generally has a stronger flavor and is most often used to make noodles and soba noodles. Common buckwheat is used more often for buckwheat flour. No matter the variety, all buckwheat is naturally gluten-free, making it a safe ingredient.

Health Benefits of Buckwheat

We have already answered the question - is buckwheat gluten-free? But beyond being gluten-free, buckwheat offers impressive health benefits.

It provides high-quality carbohydrates, all eight essential amino acids needed for growth and repair, and various vitamins and minerals. Some of the top nutrients found in buckwheat include:

  • Manganese: Whole grains like buckwheat are among the richest sources of manganese. Just one cup of buckwheat flour provides over 90% of the recommended daily intake. Manganese supports bone health, nutrient absorption, metabolism, and blood sugar regulation.
  • Magnesium: Buckwheat is an excellent source of Magnesium. Magnesium is involved in over 300 biochemical reactions in the body and supports muscle, nerve, and immune function.
  • Copper: An important mineral, copper helps form red blood cells, maintain nerve cells, support collagen production, and improve immune function. Buckwheat provides around 20% of the RDI per cup cooked.
  • Protein: High-quality plant-based proteins are beneficial for health. Buckwheat contains all essential amino acids, making it a complete protein source. Per cup cooked, buckwheat provides around 6 grams of protein.
  • Fiber: With almost 5 grams of fiber in each cooked cup, buckwheat helps regulate digestion. Fiber also lowers cholesterol and blood sugar levels.

So, is buckwheat gluten-free? - yes. Does it provide health benefits? - yes. However, there are some drawbacks to buckwheat. Let’s explore what they are. 

Antioxidants Bind with Harmful Substances

Buckwheat also contains antioxidant compounds like rutin, quercetin, and bound phenolic acids. These antioxidants bind with harmful substances and prevent oxidative damage to cells.

In particular, rutin is linked to reducing inflammation, lowering blood pressure, and improving blood flow. The high antioxidant and nutrient content contribute to the many health benefits attributed to buckwheat.

It is also naturally gluten-free and easy to find. Whether you have celiac disease, a wheat allergy, or simply want to follow a gluten-free diet, being aware of gluten-free whole grains like buckwheat is important. Substituting buckwheat flour for regular flour is an easy way to boost nutrition.
