What Are Surimi Sticks Made Of?
Surimi, the base for what we commonly call crab sticks or imitation crab, has roots in 12th-century Japan as a way to preserve fish. The term translates to "ground meat" in Japanese and the modern production process is far more complex than the original method. A highly processed food, surimi begins with low-fat, white-fleshed fish, most commonly Alaska pollock, which is minced and repeatedly washed to remove fat and odor.
The resulting fish paste is then mixed with a cocktail of additional ingredients before being cooked and pressed into the stick or flake shapes we recognize. The key added ingredients that impact its health profile include:
- Water: To help achieve the desired texture and control costs.
- Starches: Often from potato, wheat, or corn, to firm up the product and make it freeze-stable.
- Sugar and Sorbitol: Added as cryoprotectants to protect the proteins from freezing damage and to add a touch of sweetness.
- Vegetable Oil: For texture, color, and shelf life.
- Salt: Essential for flavor and to help the fish proteins form a sturdy gel structure.
- Egg Whites or Soy Protein: To boost protein content and improve texture.
- Flavorings and Colorings: Including artificial and natural crab flavorings, and colorants like paprika or carmine, which is derived from insects.
Nutritional Profile: The Pros and Cons
Assessing whether surimi sticks are a healthy choice depends on how you weigh their benefits against their drawbacks. While they are not as nutritionally robust as whole fish, they do offer a few advantages.
The Upsides
- Low in Fat and Calories: For those watching their weight, surimi is a low-fat and low-calorie option. A single serving can contain under 100 calories.
- Source of Protein: Although lower in protein than fresh fish, surimi still contributes to your daily protein intake.
- Some Essential Nutrients: Depending on the brand and fish used, surimi can provide trace amounts of minerals like selenium and phosphorus, and sometimes added omega-3 fatty acids.
- Convenience and Affordability: Pre-cooked and ready to eat, surimi is a budget-friendly and easy-to-use ingredient for salads, sandwiches, and sushi.
The Downsides
- High Sodium Content: The addition of salt is crucial for processing, resulting in a high sodium load. Some varieties contain a significant portion of the recommended daily intake in a single serving.
- Added Sugars and Carbohydrates: Unlike real crab, surimi contains added sugar and starch, increasing its carbohydrate count.
- Less Nutritious than Whole Fish: Processing and added ingredients mean surimi contains far fewer vitamins and minerals, such as B12 and zinc, compared to real, unprocessed seafood.
- Highly Processed: With its long list of ingredients and extensive processing, surimi is considered a highly processed food, often with chemical additives.
Comparison Table: Surimi Sticks vs. Real Crab
| Nutritional Aspect | Surimi Sticks (approx. 3 oz) | Alaskan King Crab (approx. 3 oz) |
|---|---|---|
| Calories | ~80-90 calories | ~82 calories |
| Protein | ~6.5 grams | ~16.5 grams |
| Carbohydrates | ~13 grams | ~0 grams |
| Sodium | ~450 mg | ~910 mg |
| Fat | ~0.4 grams | ~1.3 grams |
| Omega-3s | Low, sometimes added | High and natural |
| Vitamins (B12) | Lower, ~21% DV | Much Higher, ~408% DV |
| Minerals (Zinc) | Lower, ~3% DV | Much Higher, ~59% DV |
Understanding the Additives in Surimi
Surimi processing relies on several additives to achieve the right consistency, flavor, and shelf life. While the FDA generally recognizes these as safe, some have been linked to potential health concerns for sensitive individuals. Common additives include:
- MSG (Monosodium Glutamate): Used as a flavor enhancer, MSG can cause side effects like headaches in some people, although definitive evidence is weak.
- Carrageenan: A gum used for stabilization, some test-tube and animal studies have linked it to inflammation and intestinal damage.
- Phosphates: Added as preservatives, these can increase the risk of kidney damage and heart disease in those with high phosphate intake, particularly those with kidney disease.
- Colorants: Natural dyes like carmine (derived from insects) or paprika are used for the characteristic reddish-orange color.

Who Should Be Cautious About Eating Surimi Sticks?
While generally safe for most people, certain groups should be mindful of their surimi consumption:
- Allergy Sufferers: People with fish allergies should avoid surimi, as it is made from fish protein. Additionally, those with shellfish, egg, or wheat allergies should be cautious, as some brands may contain extracts, egg whites, or wheat starch. Inadequate labeling in some instances can increase this risk.
- Individuals on Sodium-Restricted Diets: Due to its high sodium content, surimi is not ideal for those managing high blood pressure or other conditions requiring low sodium intake.
- People with Diabetes or on Low-Carb Diets: The added starches and sugars make surimi less suitable than real crab for those managing blood sugar or following ketogenic diets.
- Health-Conscious Consumers: Anyone seeking maximum nutritional density from their seafood is better off with unprocessed fish, which offers a broader range of nutrients, especially omega-3 fatty acids.
Healthier Alternatives to Surimi
If you're looking for alternatives that offer better nutritional value, consider these options:
- Unprocessed Fish: Fresh pollock, cod, or other whitefish are excellent choices. They provide more protein, vitamins, and minerals with no added sugar or starch.
- Other Lean Protein Sources: Chicken breast, legumes, or eggs can serve as versatile protein replacements in many recipes.
- Plant-Based Alternatives: For a similar texture, ingredients like artichoke hearts or hearts of palm can be seasoned to create a crab-like salad, perfect for vegans or those with fish allergies.
Conclusion: Moderation Is Key
So, are surimi sticks healthy to eat? They can be part of a balanced diet when consumed in moderation. On the one hand, surimi is a low-fat, low-calorie, and affordable source of protein. On the other, it is a highly processed product containing added sugar, starch, and high levels of sodium. For optimal nutrition, unprocessed seafood is a superior choice. If you enjoy surimi, enjoy it as an occasional treat, mindful of its additive and sodium content. Reading the ingredient label is always recommended to understand exactly what you are eating, and opting for brands with more natural ingredients can be a healthier choice if available.
