Is Seafood High or Low in Calories? A Comprehensive Nutrition Diet Guide

4 min read

Contrary to common belief, most types of seafood are considered a low-calorie food compared to other protein-rich meats. A diverse range of fish and shellfish can be central to a healthy nutrition diet, but the total calorie count depends heavily on the specific type of seafood and its preparation method.

Quick Summary

Seafood calories vary significantly depending on the species and cooking method. Leaner varieties like cod and shrimp are low-calorie, while fattier fish like salmon are higher in calories due to healthy omega-3 fats. Understanding these differences and choosing appropriate preparation is key for a healthy diet.

Key Points

  • Calorie Variation: The calorie content of seafood differs greatly depending on the species, from very lean white fish to fattier, omega-3-rich varieties.

  • Lean Options: Low-calorie champions include cod, haddock, flounder, shrimp, and crab, which are high in protein and low in fat.

  • Fatty Options: Higher-calorie seafood like salmon, mackerel, and sardines contain more calories due to their high levels of healthy omega-3 fatty acids.

  • Cooking Method is Key: Frying seafood significantly increases its calorie count, while baking, grilling, steaming, or broiling keeps it low and healthy.

  • High in Protein: All seafood is an excellent source of high-quality protein, which helps increase satiety and is crucial for muscle repair and growth.

  • Rich in Nutrients: Seafood provides essential nutrients like omega-3s, vitamin D, vitamin B12, iodine, and selenium that support heart, brain, and immune health.

  • Beneficial for Weight Loss: Due to its high protein and satisfying nature, replacing higher-fat meats with seafood can aid in weight loss and maintenance.

The Calorie Spectrum of Seafood

When considering seafood for a healthy diet, the answer to "Is seafood high or low in calories?" is nuanced. The calorie content spans a wide range, primarily determined by the species' fat content and how it's prepared. Most seafood is a fantastic source of high-quality protein, which aids in satiety and can be beneficial for weight management. However, to make informed choices, it's essential to differentiate between lean and fatty options.

The Low-Calorie Seafood Champions

Lean white fish and many shellfish are excellent low-calorie choices, providing a substantial amount of protein without excess fat. These options are perfect for those aiming for weight loss or a calorie-controlled diet.

Here are some of the top low-calorie seafood options:

  • Cod: A 3-ounce cooked serving contains only about 90 calories and less than 1 gram of fat.
  • Flounder/Sole: Extremely low in calories, with a 3-ounce portion typically containing 100 calories or less.
  • Shrimp: A 3-ounce serving of boiled or steamed shrimp has only about 101 calories.
  • Crab: Whether blue crab or Alaskan king crab, a 3-ounce portion offers between 70 and 95 calories.
  • Scallops: These mollusks are low in calories and an excellent source of protein, with a 3-ounce serving of steamed scallops containing about 95 calories.

The Higher-Calorie, Nutrient-Dense Options

Some of the healthiest seafood options are higher in calories because they are rich in beneficial omega-3 fatty acids. These healthy fats are crucial for heart and brain health, and their presence makes these fish incredibly nutrient-dense.

  • Salmon: A 3-ounce cooked serving of Atlantic salmon contains around 175 calories, primarily from omega-3s.
  • Mackerel: Another excellent source of omega-3s, a 3-ounce serving of cooked mackerel has about 190 calories.
  • Sardines: While canned sardines in oil are higher in calories (around 191 calories for 3.5 ounces), they are packed with healthy fats, protein, and calcium.
  • Herring: A 3-ounce cooked portion of herring provides around 170 calories and is rich in omega-3s.

How Preparation Method Impacts Seafood Calories

The way seafood is cooked is arguably the most significant factor in its final calorie count. Choosing healthy cooking methods can keep even fattier fish a lean meal option, while unhealthy methods can add hundreds of calories to even the leanest seafood.

Healthy Cooking Methods

  • Grilling: Uses minimal added fat and is excellent for all types of fish.
  • Baking: Requires little to no oil and is ideal for both fillets and whole fish.
  • Steaming: A no-fat method that preserves the natural flavor and nutrients.
  • Broiling: Uses direct high heat to cook quickly and create a satisfying texture.

Unhealthy Cooking Methods

  • Frying and Battering: Deep-frying seafood, such as fish and chips, can more than double the calorie and fat content due to the oil absorption.
  • Heavy Sauces: Using large amounts of butter, cream, or other high-calorie sauces will dramatically increase the calorie count, even if the seafood itself is lean.

Comparing Seafood Calories and Macronutrients

This table highlights the difference in nutritional profiles for a standard 3-ounce (approx. 85g) cooked serving of various seafood types, showing how both species and preparation method affect the final dish.

Seafood Type Preparation Calories (kcal) Total Fat (g) Protein (g) Key Feature
Atlantic Cod Baked/Broiled ~90 ~1 ~20 Very lean white fish
Pink Salmon Canned (drained) ~141 ~6.2 ~25 Moderate fat, good omega-3s
Atlantic Salmon Baked ~175 ~10.5 ~22 Fatty fish, rich in omega-3s
Shrimp Boiled/Steamed ~101 ~1.5 ~17 Low-fat shellfish
Shrimp Battered and Fried ~206 ~10.4 ~17 Significantly higher in calories
Sardines Canned in Oil ~168 ~7 ~22 Higher fat, excellent omega-3 source
Oysters Baked/Grilled ~67 ~1.8 ~12 Low-calorie shellfish

Making the Right Choice for Your Nutrition Diet

Incorporating seafood into your diet offers a wide range of health benefits beyond just calorie control. It is an excellent source of omega-3s (EPA and DHA), which are vital for heart and brain health, reducing inflammation, and even improving mood. It also provides a great source of lean protein, which is essential for building and repairing muscle tissue and promoting feelings of fullness. Vitamins and minerals, including vitamin D, B12, selenium, and iodine, are also found in abundance in many types of seafood.

To make the best choices:

  • Vary your intake. Alternate between lean and fatty fish throughout the week to get a full spectrum of nutrients.
  • Prioritize healthy cooking. Opt for grilling, baking, steaming, or broiling over frying to keep calorie counts in check and avoid excess saturated fat.
  • Read labels. For canned or frozen products, check for added salt, oils, or sugars. Tuna canned in water is lower in calories than tuna canned in oil.

Conclusion: Making Informed Choices About Seafood Calories

Ultimately, whether seafood is high or low in calories is entirely dependent on the specific type and how it is prepared. Most varieties, especially lean white fish and shellfish, are low in calories and rich in protein, making them an ideal choice for weight management. Fattier fish, though higher in calories, are an invaluable source of heart-healthy omega-3s and other vital nutrients. By choosing a variety of seafood and preparing it with healthy cooking methods, you can maximize its impressive health benefits while maintaining control over your calorie intake.

Some of the lowest-calorie seafood options include lean white fish like cod, flounder, haddock, and sole. Shellfish such as shrimp, crab, and scallops are also excellent low-calorie choices.

Fatty fish do contain more calories than lean fish, but these calories come from healthy unsaturated fats, specifically omega-3 fatty acids. This makes them a nutrient-dense and beneficial food, especially for heart and brain health.

The cooking method is crucial. While steaming, baking, or grilling adds minimal calories, frying or cooking with high-fat sauces can dramatically increase the calorie count of any seafood.

The calorie count of canned tuna depends on the packing medium. Tuna canned in water is a low-calorie protein source, whereas tuna canned in oil is higher in calories and fat.

The American Heart Association and other health organizations recommend eating fish at least two times per week. Including at least one serving of an oily fish, like salmon or mackerel, is particularly beneficial for its omega-3 content.
