Is Octopus High in Calories? The Surprising Truth

3 min read

With approximately 70-85 calories per 100-gram serving when raw, octopus is not high in calories at all. This nutrient-dense mollusk is actually celebrated for being a lean source of protein, making it an excellent addition to a health-conscious diet.

Quick Summary

Octopus is a lean, low-calorie seafood packed with protein and essential nutrients like vitamin B12 and selenium. The final calorie count depends heavily on the cooking method, with deep-frying adding significant calories compared to grilling or boiling.

Key Points

  • Low-Calorie Profile: A typical 100g serving of raw octopus is surprisingly low in calories, usually between 70 and 85 calories.

  • High-Protein Source: Octopus is an excellent source of lean protein, containing around 16-19 grams per 100g, promoting satiety and muscle building.

  • Nutrient-Dense: It is packed with essential nutrients, including significant levels of vitamin B12, selenium, iron, and copper.

  • Cooking Method Matters: Preparation heavily influences the final calorie count; simple methods like grilling or boiling keep calories low, while deep-frying adds significant fat.

  • Health-Conscious Choice: Ideal for weight management and healthy diets, offering a satiating protein source with fewer calories than many other meats.

  • Part of a Balanced Diet: Best consumed in moderation as part of a varied diet, mindful of potential mercury content and high sodium in some processed versions.

Understanding the Nutritional Profile of Octopus

Octopus is often misunderstood, with many assuming its unique texture and flavor translate to a high-calorie profile. However, a standard 100-gram (about 3.5-ounce) serving of raw octopus contains around 70-85 calories, less than 2 grams of fat, and a healthy portion of protein, typically around 16 to 19 grams. This makes it a formidable component of a balanced, low-calorie diet, especially when compared to many other protein sources. Beyond its lean macros, octopus is an absolute powerhouse of vitamins and minerals.

The Micronutrient Powerhouse

  • Vitamin B12: A 100-gram serving can provide well over 100% of the Daily Value (DV), which is essential for nerve function and red blood cell formation.
  • Selenium: Offering over one-third of your DV, selenium acts as a powerful antioxidant, combating oxidative stress.
  • Iron and Copper: These minerals are crucial for energy production and red blood cell formation, with octopus providing substantial amounts.
  • Omega-3 Fatty Acids: Though not as rich as fattier fish, octopus contains beneficial omega-3s, which are linked to heart health benefits.

The Impact of Cooking Method on Calories

While raw octopus is inherently low-calorie, its preparation is the most significant factor influencing its final nutritional value. Simple cooking methods preserve its lean nature, while heavy-handed techniques can drastically increase the calorie count.

  • Low-Calorie Methods: Grilling, boiling, or steaming are the best options for those mindful of calorie intake. These methods add little to no extra fat, allowing the natural low-calorie profile of the octopus to shine. A grilled octopus salad with lemon juice and a drizzle of olive oil is a prime example of a healthy, delicious meal.
  • High-Calorie Methods: Deep-frying, a common preparation style for calamari (squid), is where the calorie count skyrockets. The batter and oil absorb into the seafood, multiplying the fat and calorie content. Similarly, dishes where octopus is cooked in large amounts of butter or oil will significantly increase the total calories. Canned octopus packed in oil will also be higher in fat.

Octopus vs. Other Seafood: A Calorie Comparison

To put octopus's low-calorie status into perspective, it's helpful to compare it with other common seafood and protein sources. This table showcases the approximate calories per 100-gram serving for various proteins, assuming simple preparation methods (e.g., boiled, grilled, or steamed).

Food Item (100g serving) Approx. Calories Protein (g) Fat (g)
Octopus (boiled) ~165 ~29 ~2.5
Chicken Breast (boiled) ~165 ~31 ~3.6
Cod (cooked) ~105 ~23 ~1
Shrimp (cooked) ~99 ~24 ~0.7
Salmon (cooked) ~208 ~20 ~13

As the table illustrates, octopus stands shoulder-to-shoulder with chicken breast in terms of protein content for a comparable, or even slightly lower, calorie cost. It also provides a significant protein boost for fewer calories than fattier fish like salmon, making it an ideal choice for weight management.

Incorporating Octopus into a Healthy Diet

Octopus is an incredibly versatile ingredient. For a satisfying, low-calorie meal, consider a Mediterranean-style octopus salad. Combine boiled, chilled octopus with fresh vegetables like bell peppers, cucumbers, and tomatoes, and dress it with lemon juice, herbs, and a small amount of high-quality extra virgin olive oil. This approach maximizes flavor while keeping the dish light.

Another option is a simple grilled octopus served with a side of steamed vegetables. The high protein and low fat content promote satiety, helping you feel full for longer and reducing the urge to snack. For those seeking a heartier dish, an octopus and brown rice bowl offers complex carbohydrates for sustained energy while maintaining overall caloric control.

Potential Health Considerations

While octopus is a highly nutritious food, it's worth noting its potential drawbacks, mainly related to mercury content and sodium levels. Like many forms of seafood, octopus can contain varying levels of mercury, so moderation is key. Additionally, some canned or pre-packaged preparations can be high in sodium, so always check the label, especially if you have blood pressure concerns.

Conclusion

In summary, the answer to the question "Is octopus high in calories?" is a definitive no. Raw and simply cooked octopus is a low-calorie, low-fat, and exceptionally high-protein seafood. Its rich profile of essential vitamins and minerals, including a remarkable amount of vitamin B12 and selenium, makes it an outstanding addition to a balanced and healthy diet. The key to enjoying octopus without drastically increasing its calorie count lies in the preparation method—favoring boiling, grilling, or steaming over deep-frying or cooking with excessive fats. By making mindful culinary choices, you can fully enjoy the nutritional benefits of this marine delicacy.
