How Many Carbs Are in Salmon Sushi?

November 23, 2025 •

4 min read

Salmon sushi offers a unique combination of rich protein and omega-3 fatty acids, but its carbohydrate content can vary dramatically depending on how it's prepared. The vast majority of carbs in most salmon sushi comes not from the fish, but from the sweetened and seasoned white rice that forms its base. Understanding these differences is key to managing your carb intake.

Quick Summary

The carb count in salmon sushi depends on the style. Sashimi contains zero carbs, while nigiri has a moderate amount. Maki rolls, especially those with extra ingredients, contain the most carbs. The main source of carbohydrates is the sticky rice, not the salmon itself. Portion size, rice type, and added sauces significantly impact the total carb count.

Key Points

Sashimi is carb-free: Thinly sliced salmon without rice contains zero carbohydrates, making it the best option for low-carb diets.
Rice is the main carb source: The carbohydrates in most salmon sushi come from the sweetened and seasoned white rice, not the fish itself.
Nigiri has fewer carbs than rolls: Salmon nigiri, with its small rice ball, contains significantly fewer carbs per piece than a maki roll.
Avoid complex rolls and sauces: Specialty rolls with tempura, cream cheese, and heavy sauces dramatically increase the carb and calorie count.
Opt for substitutions: To reduce carbs, choose brown rice over white, or ask for cucumber-wrapped rolls instead of rice-based versions.

The Surprising Source of Carbs in Salmon Sushi

Many assume that sushi is a low-carb, healthy meal, focusing only on the fish. However, this assumption overlooks the primary source of carbohydrates: the rice. A 2-piece serving of raw salmon nigiri can contain around 16.7 grams of total carbohydrates, derived almost entirely from the bed of sticky, vinegar-seasoned white rice. The salmon itself is naturally carb-free. For those monitoring their carb intake, differentiating between types of salmon sushi is crucial.

Salmon Sashimi: The Zero-Carb Option

If you're seeking a genuinely zero-carb experience, salmon sashimi is your best choice. Sashimi is simply thinly sliced, high-quality raw salmon served without rice. A 150g serving of salmon sashimi contains zero carbs, along with a good source of protein and healthy fats. This makes it an ideal option for individuals on ketogenic, paleo, or other low-carbohydrate diets.

Salmon Nigiri: A Moderate Carb Choice

Salmon nigiri consists of a slice of raw salmon draped over a small, hand-pressed ball of vinegared rice. This form offers a balance of fish and rice. The amount of carbs depends on the size of the rice ball, but a typical 2-piece serving contains approximately 12 to 17 grams of carbohydrates. This is a more manageable carb count for many diets compared to heavily rolled sushi.

Salmon Maki Rolls: The Highest Carb Contender

Salmon maki rolls, especially those with added ingredients and sauces, carry the highest carbohydrate load. Standard maki rolls are created with a larger quantity of rice than nigiri. For example, a 6-piece salmon maki roll can contain around 30 grams of carbohydrates. Americanized rolls, such as a spicy salmon roll with mayo-based sauces, can have an even higher carb count due to added sugar and other ingredients. Some specialized rolls can have up to 71 grams of carbs per serving.

How to Choose Lower-Carb Salmon Sushi

Navigating a sushi menu with a focus on carb control is straightforward once you know what to look for. Here are some key strategies:

Choose Sashimi First: As the most obvious low-carb option, prioritize sashimi. You still get the full flavor and health benefits of the salmon without any added carbs from the rice.
Opt for Nigiri over Rolls: If you want a taste of rice, nigiri provides a smaller rice-to-fish ratio than maki rolls. Stick to just a few pieces to keep the carbs in check.
Customize Your Order: Don't be afraid to ask for modifications. Many restaurants can prepare rolls with less rice or use cucumber wraps instead of rice (sometimes called a "naruto roll").
Ask for Brown Rice: While still containing carbs, brown rice has more fiber and a slightly lower glycemic index than white rice, leading to a slower rise in blood sugar.
Watch the Sauces: Creamy, sweet, and spicy sauces are often hidden sources of sugar and calories. Ask for sauces on the side or avoid them altogether.

Naruto Roll (Cucumber-Wrapped)	None	Very low or 0g	Yes

Understanding Why Sushi Rice Contains Carbs

Sushi rice is not just plain white rice. It is prepared with a specific seasoning mixture of rice vinegar, sugar, and salt, which further contributes to its overall carbohydrate content. The sugar helps balance the flavor and provides the distinct glossy texture. This added sugar is another factor to consider when evaluating how many carbs are in salmon sushi and how it fits into your dietary plan.

The Role of Glycemic Index

White rice is a refined carbohydrate with a high glycemic index, meaning it can cause a rapid spike in blood sugar levels. This can be a concern for individuals with diabetes or those trying to manage their weight. By choosing alternatives like brown rice or consuming smaller portions, you can help mitigate these effects. Sashimi, with its zero-carb profile, bypasses this issue entirely.

Conclusion: Making Informed Choices

When asking how many carbs are in salmon sushi, the answer is not simple, but it is empowering. While the salmon itself is a protein-rich, zero-carb food, the final carb count is determined by the preparation style. For the lowest carb option, sashimi is the clear winner. For a moderate rice experience, nigiri is a better choice than maki rolls. By understanding these distinctions, you can enjoy the nutritional benefits of salmon while staying in control of your dietary goals.
