Buckwheat is a highly nutritious whole grain that many people consider to be a superfood. Among its health benefits, buckwheat may improve heart health, promote weight loss, and help manage diabetes.

Buckwheat is a good source of protein, fiber, and energy. Buckwheat does not contain gluten, so for people with celiac disease or gluten intolerances, buckwheat and buckwheat flour are excellent dietary alternatives.

This article will discuss the nutrition, health benefits, and side effects of buckwheat.

Buckwheat is an ingredient in many everyday food products, such as breakfast foods, flour, and noodles. Farmers also use it for livestock feed.

Buckwheat contains a variety of healthful nutrients. It is a good source of protein, fiber, and healthful complex carbohydrates.

One cup, or 168 grams (g), of roasted, cooked buckwheat groats (hulled seeds) contains the following nutrients:

  • 5.68 g of protein
  • 1.04 g of fat
  • 33.5 g of carbohydrate
  • 4.5 g of fiber
  • 148 milligrams (mg) of potassium
  • 118 mg of phosphorous
  • 86 mg of magnesium
  • 12 mg of calcium
  • 1.34 mg of iron

Buckwheat also contains vitamins, including:

  • thiamin
  • riboflavin
  • niacin
  • folate
  • vitamin K
  • vitamin B-6

The following sections look at the evidence for possible health benefits of adding buckwheat to the diet.

1. Boosting heart health

As a whole grain, buckwheat could have benefits for heart health.

The American Heart Association (AHA)Trusted Source recommend that at least half the grains in a person’s diet should be whole grains. Whole grain foods contain nutrients that are important for heart health, including fiber and niacin.

A 2015 systematic review found a link between diets that were higher in whole grain foods and a lower risk of heart disease. Animal studies have foundTrusted Source that buckwheat may lower blood pressure, which can also improve heart health.

People who follow gluten-free diets may consume lower intakes of whole grains, which means they miss out on the health benefits they provide. Including buckwheat into the diet as an alternative to whole grains that contain gluten can deliver these benefits.

Buckwheat is a good source of fiber. According to the AHATrusted Source, dietary fiber helps improve blood cholesterol levels, which, in turn, reduces the risk of heart disease, diabetes, stroke, and obesity.

2. Improving digestion

Buckwheat is rich in fiber. Dietary fiber is a type of plant-based carbohydrate that the body cannot break down during digestion.

Fiber supports the intestines in digesting food efficiently and helps food move through the digestive tract. It may also have other benefits, such as encouraging weight loss and preventing cardiovascular disease.

One cup of buckwheat also contains 1.58 mg of the recommended 14 to 16 mg of niacin for adults. Niacin, or vitamin B-3, is essential for converting carbohydrates, fats, and proteins into energy for the body’s cells to use.

Being a good source of fiber and niacin makes buckwheat a good choice for digestive health.

3. Weight management

Buckwheat is also a good option for weight management.

Satiety is the feeling of fullness after a meal. It is an important concept in preventing weight gain or promoting weight loss. Foods that increase satiety can offset hunger for more extended periods and may reduce the total number of calories a person consumes during a day.

Buckwheat is high in protein. Research has found that high-protein foods are essential for weight management because they lead to greater satiety with fewer calories than other types of food.

Including buckwheat in a healthful diet could lead to greater satiety and help with weight management. However, scientists will need to do further research into the effect of buckwheat and other whole grains to confirm this.

4. Managing diabetes

As a whole grain, buckwheat is a source of complex carbohydrate. This form of carbohydrate can help people manage their blood glucose levels.

The body takes longer to break down complex carbohydrates than simple carbohydrates. This slows down digestion and helps keep blood sugar levels stable for longer. White bread is an example of a simple carbohydrate.

According to the American Diabetes Association, whole grain foods are a good source of carbohydrate. These foods are an excellent source of energy and can provide fiber and minerals.

Animal research has found that buckwheat had a positive effect on insulin and blood glucose in mice with diabetes on a high-glucose diet. However, it is unclear whether these findings extend to humans with diabetes.
