What Are Soba Noodles?

Soba noodles are made from buckwheat flour and are popular in Japanese cuisine. These have a nutty flavor and chewy texture and can be consumed both hot and cold. People in Japan make it a point to eat soba noodles on the evening of December 31st as part of a tradition that started between 1603 and 1867 (Edo period).

Soba noodles are available in different varieties depending on the amount of buckwheat flour used and flavorings added. Here are a few common types.

Types Of Soba Noodles

  • Nihachi Soba

This is the most commonly found variety of soba noodles in the United States. It contains about 80% of buckwheat flour and 20% wheat flour. When mixed, wheat flour strengthens buckwheat flour and makes the noodles smoother.

  • Juwari Soba

This is the most traditional version of soba noodles and is made using 100% buckwheat flour. These noodles have a nutty taste, earthy flavor, and grainy texture and can be enjoyed warm or cold. Besides, these noodles are a good source of protein.

  • Sarashina Soba

These whitish noodles are made only with the endosperm (a tissue produced inside the seeds) of buckwheat. They have a delicate aroma, a more refined flavor, and a subtle sweetness.

  • Inaka Soba

Inaka soba noodles are made with ground un-hulled buckwheat seeds for a darker color. These are thicker than sarashina soba and have a strong aroma.

  • Cha Soba

These noodles are made using green tea powder, wheat flour, and buckwheat flour. These have a subtle scent and flavor of green tea, and are known for their delicacy. Besides, cha soba can be served both hot and cold, and is mostly consumed on special occasions.

How nutritionally rich are soba noodles? Here is a breakdown of their nutrient profile.

Health Benefits Of Soba Noodles

1. May Reduce The Risk Of Heart Disease

A study conducted on 850 ethnic minorities in Southeast China found that intake of oats and buckwheat had cholesterol-lowering effects. The findings suggest that buckwheat is associated with lower serum total cholesterol and LDL cholesterol, and a higher ratio of HDL to total cholesterol (2).

Most animal studies also support these findings. Moreover, buckwheat intake was also shown to reduce triglyceride levels (3). This gluten-free pseudocereal also has the potential to reduce plasma cholesterol levels and hypertension (4). All these factors help reduce the risk of cardiovascular disease.

2. May Help Control Blood Sugar Levels

The high starch content and low glycemic index values of buckwheat food items like soba noodles help control blood sugar levels. Foods with low glycemic values digest slowly and prevent a sudden spike in blood sugars. Similarly, the rate of starch hydrolysis of boiled buckwheat noodles was found to be low. Hence, soba noodles help with glycemic control and may be included in diets designed for people with diabetes (5), (6). A review published in the Journal of Education and Health Promotion suggests that whole grain products like buckwheat help prevent and control type-2 diabetes (7).

3. Have Anti-Inflammatory Properties

Buckwheat and its products show anti-inflammatory properties, which help prevent and treat inflammatory bowel diseases (8). Buckwheat’s bioactive compounds like flavonoids may also help improve chronic inflammatory conditions (9). These polyphenolic compounds also have the potential to inhibit the onset and development of inflammatory diseases (10).In addition, whole grain intake is also inversely associated with inflammation (11).

4. May Help Treat Varicose Veins

Rutin, a citrus flavonoid in buckwheat, has a protective role in treating various ailments like varicose veins, internal bleeding, or hemorrhoids. Findings from the study conducted by Guru Ghasidas University (India) suggest that rutin may be developed as a food supplement to cope with acute organ dysfunctions caused by inflammatory and oxidative damage (12). However, more studies are needed to understand this benefit of buckwheat or soba noodles.

5. Is A Prebiotic Food

Buckwheat could significantly increase aerobic mesophilic and lactic acid bacteria in rats. These findings suggest that buckwheat could possibly be considered as a prebiotic product (13). Prebiotics may help prevent diarrhea, reduce the risk of cancer, stimulate mineral absorption, and improve lipid metabolism (14).

6. May Help With Weight Loss

Buckwheat is very high in protein. Studies suggest that consumption of a protein-rich diet may help with weight loss (15). Jamie Hickey, Registered Dietitian, says, “These noodles contain an ingredient called konjac (Amorphophallus konjac), which is native to Asia and Southeast Asia in particular. Konjac is packed with dietary fiber that fills the stomach, ensuring that appetite stays in control”.

Include soba noodles in your diet to reap all these health benefits. But does this Japanese dish cause any side effects? Scroll down to know.

Side Effects Of Soba Noodles

Consuming soba noodles is generally considered safe. However, buckwheat may cause some allergic reactions like anaphylaxis, bronchospasm (acute narrowing of your airways) and urticaria (skin rashes) in elderly people. These cases are commonly reported in Europe and Asia (16). Moreover, buckwheat flour is often mixed with wheat flour to make soba noodles. Hence, people sensitive to wheat may experience allergic reactions. Therefore, always go through the product labels to check if there are any gluten-containing grains in the product (17).

Soba noodles have a wide commercial presence. However, you can also prepare these noodles at your home easily. Let us find out how.

How To Make Soba Noodles Easily At Home?

What You Need

  • Stone-milled buckwheat flour – 2 cups (280 grams)
  • Filtered or mineral water – ¾ cup
  • All-purpose flour – ½ cup
  • Buckwheat starch – for rolling the soba


  1. Gradually add water to the sifted flour mixture, tossing with your fingertips until flour is incorporated and forms a crumbly mixture.
  2. Knead the mixture in a circular motion until it begins to form small clumps (about 2 minutes).
  3. Gather dough and shape into a large ball. Knead until it is semi-firm and smooth. Press the ball into a one-inch-thick disk.
  4. Roll the dough into an 18-inch square (about 1/8 inch thick) on a surface dusted with tapioca starch. Trim the edges to create an even square.
  5. Sprinkle half of the dough with tapioca starch. Fold in half lengthwise. Sprinkle again and fold in half to create a 9-inch square with four layers of dough.
  6. Cut the dough into thin noodles using a ruler or cutting guide. Tap on the cutting board to remove excess starch.

You need to store soba noodles properly to enhance their shelf life. In the next section, we bring to you some important storage tips you may consider.

How To Store Soba Noodles?

Like pasta, dry soba noodles can last up to two years if you store them in a cool, dry place. They do not require refrigeration, and you need to keep them away from moisture. Freshly made soba noodles can last for 1 to 3 days in the fridge. But if you want to freeze them after cooking, drain the water and place them in a Ziploc bag. They can last two weeks if you freeze-dry them.
