What Contributes to the High Carbohydrate Count?
Unlike real crab meat, which is a pure protein source, imitation crab is a highly processed food product known as surimi. The ingredients required to manufacture surimi are responsible for its carbohydrate content. To create the pliable, crab-like texture, minced white fish—most commonly Alaskan pollock—is mixed with binders and flavor enhancers. The binding agents and additives, particularly starches and sugar, are the main culprits for the elevated carb count.
Key ingredients and their role in carbohydrate content
- Starch: Ingredients such as wheat starch or modified tapioca starch are added to surimi to bind the minced fish paste together and give it a firm, yet flaky, texture. This is the most significant source of carbohydrates.
- Sugar: Sucrose, sorbitol, and other sweeteners are typically included to enhance the flavor and provide a mild sweetness. This contributes directly to the sugar content, which is a type of carbohydrate.
- Egg Whites: While primarily a protein source, egg whites can sometimes contribute a minimal amount of carbs depending on processing.
- Flavorings: Various natural and artificial flavorings are used to mimic the taste of real crab, but they do not typically add significant carbs.
It is this combination of starches and sugars that pushes imitation crab's carbohydrate count into a range that makes it a poor choice for those on very low-carb or ketogenic diets.
Imitation Crab vs. Real Crab: A Nutritional Comparison
For those monitoring their carb intake, the nutritional difference between imitation crab and real crab is substantial. Real crab is a naturally carb-free food, while imitation crab relies heavily on them. Below is a comparison table that highlights the stark differences in macronutrient composition.
| Feature | Imitation Crab (per 85g serving) | Alaskan King Crab (per 85g serving) |
|---|---|---|
| Calories | Approx. 81 calories | Approx. 71 calories |
| Total Carbs | Approx. 12.8 grams | 0 grams |
| Protein | Approx. 6.5 grams | Approx. 15.6 grams |
| Fat | Less than 1 gram | Less than 1 gram |
| Sodium | 450+ milligrams (can vary) | 910 milligrams (can vary) |
The table clearly shows that imitation crab derives a significant portion of its calories from carbohydrates, whereas real crab is primarily protein. This is the key nutritional difference that affects low-carb and ketogenic diets.

Reading the Label: Understanding the Carb Count
Because the exact amount of starch and sugar varies by brand, it is essential to read the nutrition label carefully. The 'Total Carbohydrate' line will give you the most accurate number to work with. If you are tracking net carbs, you will need to subtract any dietary fiber listed. Some brands may contain more filler and sugar than others, leading to a wider range of carbohydrate values. For instance, a 1-cup serving of one brand might have nearly 19 grams of total carbs, while an 85g serving of another has closer to 13 grams. Always assume imitation crab is a source of carbohydrates, and check the label to determine if it fits your dietary needs.
Low-carb cooking with imitation crab
If you still wish to incorporate imitation crab into your meals on a low-carb diet, moderation is key. Here are some tips:
- Portion Control: Use a smaller serving size than you might normally. A few pieces shredded into a salad will add flavor without significantly impacting your carb count.
- Paired Ingredients: Focus on pairing it with low-carb, keto-friendly ingredients like leafy greens, avocados, cucumber, and full-fat mayonnaise.
- Alternative Uses: Instead of making a traditional crab salad sandwich, use the mixture as a stuffing for avocados or cucumber boats.
Conclusion
While imitation crab is a more affordable and readily available alternative to real crab, it is not a low-carbohydrate food. Its high carb content comes from the starches and sugars added during the manufacturing of surimi, the processed fish paste it is made from. Anyone on a strict low-carb or ketogenic diet should be mindful of the significant carb load in imitation crab and opt for real crab meat if possible. Always check the nutrition facts label to know the precise carb count for the specific brand you are consuming.
