Is Wasabi Keto? Less Is More Rule: Wasabi Peas, Powder & Paste

Is wasabi keto friendly, and what about wasabi peas, powder and paste?¹⁰

All forms of wasabi have all sorts of impressive health benefits and although wasabi has a high number of carbohydrates per the 1 serving size of 1 tablespoon, wasabi could be enjoyed in moderation due to its pungent flavor.

Which goes to say, wasabi is keto due to the small serving sized and so long as you follow the less is more rule (eating small quantities), then you’re in the clear keto wise.

That being said, we’ll cover the exact number of carbs in normal wasabi — from peas, powder and paste — as well as the array of health benefits.

Wasabi Carbs: Does Wasabi Have Carbs?

Wasabi paste has approximately 7 grams of carbohydrates per 1 tablespoon. When following a keto diet, someone typically aims to limit their carb intake to about 20-50 grams per day.¹ 

Therefore, a great rule of thumb when wondering is wasabi keto and deciding whether it should be included in someone’s diet is less is more. With a serving size of 1 tablespoon, wasabi has too many carbs to be suitable for a keto diet so moderation is key here.

It’s important to remember that wasabi does have such a strong flavor so a little amount can go a long way. 

Whereas 1 tablespoon of wasabi has 7 grams of carbs, 1 teaspoon only has 2 carbs per serving which is a much more reasonable amount to be allowed on keto.

Is Wasabi Keto-Friendly?

The answer to the question is wasabi keto could be a yes depending on serving sizes. Looking at the nutrition breakdown for 1 tablespoon of wasabi paste, this amount can be seen as too much for a keto diet because there are 7 grams of carbohydrates. 

While there are different variations of a keto diet, the basic keto diet includes a macro breakdown of about 55-60% fat, 30-35% protein, and 5-10% carbohydrates, which can be between 20-50 grams of carbohydrates each day.³ Thus, 7 grams of carbohydrates for 1 tablespoon of a condiment would be too much. 

In order for wasabi to be keto-approved moderation is key and the “less is more” rule must be followed. This could be easily achieved due to the strong flavor wasabi paste has so a small quantity could go a long way.

All in all, a tablespoon of wasabi is too much for a keto diet, while 1 teaspoon of wasabi only has 2 grams of carbs so small quantities of wasabi can be eaten on a keto diet. 

What Is Wasabi & How Is It Made? 

Wasabi is a spicy, green paste typically served with sushi at Japanese restaurants that offer sake, so knowing is sake keto-approved is helpful. Real wasabi is made from finely grating the rhizome, or underground stem part of a plant of the mustard family called the brassicaceae. 

It is interesting to know that wasabi found outside of Japan is most likely not real wasabi because the plant is very expensive and difficult to find as it is only native to Japan. 

This plant actually grows wild in Japan but is difficult to grow because it requires being submerged in moving water, a very rare farming structure. Furthermore, it is very sensitive to environmental changes and humidity, so overall this plant is very challenging to grow outside of its native Japan. 

Wasabi made in western cultures is most often made from a different plant in the mustard family, horseradish. Typically imitation wasabi will sometimes include a very small amount of real wasabi, ranging between 1 and 3%. 

Interestingly, because of this, most people outside of Japan have most likely not tasted real wasabi. 

What Types of Wasabi Are There? Powder vs Paste

Wasabi can come in powder and paste form. Wasabi powder is made by drying the wasabi plant and grinding it into a fine powder. 

It can be more versatile as it can be sprinkled on fish, mixed with breadcrumbs for a spicy crusted chicken breast, and more. Additionally, water can be added to the powder to make wasabi paste. 

Wasabi paste may be the more recognizable product as it is almost always served with sushi. Believe it or not, wasabi paste can also be used in a lot of different ways, such as being added to dipping sauces such as mayonnaise, butter, or hummus and used for marinating meats. 

Some ice cream shops even offer wasabi ice cream!

Interestingly, most powdered and pasted wasabi sold is not pure, real wasabi and instead made with horseradish. It can be fairly easy to spot the difference between real and fake wasabi based on texture. 

If the wasabi is thick and pasty this is a sign it is not real and is made from horseradish. Real wasabi will have a grated and gritty texture instead of a smooth one. 

One final common wasabi product consumers can find are wasabi peas. These are very popular snacks in Japan that are found all over. 

They are dried and roasted green peas seasoned with oil, salt, sugar, and wasabi. These are a great, healthier option compared to potato chips because they are peas but unfortunately, they should be avoided while on a keto diet unless consumed in a very small amount because they do have a significant number of carbs.

Pure wasabi powder and wasabi peas do have a different nutritional breakdown compared to wasabi paste.

Here is the breakdown for 1 teaspoon of 100% pure wasabi powder compared with 1 teaspoon of wasabi paste and 1 serving size of wasabi peas which is 1 ounce or about 55 wasabi peas.

What Are the Health Benefits of Wasabi? Is Wasabi Good for You?

When wondering is wasabi keto, someone may also be curious to know if wasabi has any health benefits. Here are 5 surprisingly amazing health benefits wasabi has. 

1. Inhibiting AA: Acrylamide (AA) is formed through some cooked foods and has been linked with damaging DNA and has the potential for causing cancer.⁴ Research has shown wasabi roots and leaves are effective ingredients to help inhibit the genotoxicity of AA.⁵
2. Improve Heart Health: Research has shown the active component, allyl isothiocyanate (AITC) in wasabi can improve cholesterol and high blood pressure.⁶
3. Antibacterial Effects: While more research is needed in this area, initial studies have shown that the AITC found in wasabi has a strong antibacterial property and has been shown to control the common foodborne outbreaks that cause food poisoning, E coli and S. aureus.⁷ 
4. Potential Weight Loss: Again, more research is needed as the primary studies focusing on weight and fat loss has been done with mice, but the initial research has shown that wasabi plant leaves have the potential to suppress the growth and formation of fat.⁸
5. May Prevent Weight Gain: Research on mice has shown that wasabi had the ability to prevent weight gain while fed a high-fat diet.⁹ Maybe wasabi could be helpful in answering the question of how to get rid of upper belly fat. 

Because pure wasabi is more expensive and the plant is difficult to grow, most wasabi contains horseradish as well. Horseradish does contain isothiocyanate (ITC) which is one of the compounds found in wasabi that has been associated with many health benefits, so the above benefits could still be present even if pure wasabi is not being consumed. 

Recipes & Ways To Use Wasabi
