Is Canned Tuna High in Calories? A Comprehensive Guide

4 min read

According to the USDA, a 5-ounce can of tuna packed in water contains approximately 120 calories, while the same size can packed in oil has around 280 calories. This significant difference in nutritional content reveals that the type of liquid canned tuna is packed in is the primary factor influencing its calorie count.

Quick Summary

This guide explains how the packing liquid drastically affects the calorie content of canned tuna, comparing water-packed and oil-packed options. It details the nutritional breakdown, explains the health implications of each, and provides tips for making the best choice based on dietary needs.

Key Points

  • Packing Liquid Determines Calories: Tuna packed in water is low in calories, while tuna in oil is significantly higher due to the added fat.

  • Water-Packed Tuna is Lean Protein: Offers a high protein-to-calorie ratio, making it an excellent choice for weight management and satiety.

  • Oil-Packed Tuna is Higher in Fat: Provides a richer flavor and moisture but comes with a higher fat and caloric load.

  • Consider Tuna Species for Mercury: Albacore (white) tuna typically has more mercury than skipjack (light) tuna, so choose accordingly based on consumption frequency.

  • Monitor Sodium Levels: Canned tuna often contains high sodium; look for low-sodium or 'no salt added' versions to control intake.

Understanding the Calorie Difference: Water vs. Oil

When asking "Is canned tuna high in calories?", the most important factor to consider is the packing medium. The difference in calories is substantial and stems from the nature of oil versus water. Oil is a source of fat, and therefore, a concentrated source of calories. Water, by contrast, contains no calories. Tuna packed in water is a very lean protein source, while oil-packed tuna will have a significantly higher fat and calorie content due to the added oil.

Why oil dramatically increases calories

Oil-packed tuna is immersed in either vegetable oil or olive oil. A typical 5-ounce can of chunk light tuna in water contains around 120 calories, whereas the oil-packed version contains approximately 280 calories. This caloric boost is almost entirely from the added fat. While some oils like olive oil provide healthy monounsaturated fats, this extra caloric load can be a consideration for those managing their weight or calorie intake. Draining the oil can help reduce the calorie and fat content, but it won't eliminate it completely.

The lean protein power of water-packed tuna

Water-packed tuna offers a leaner nutritional profile, making it a favorite for those focused on weight management or increasing protein intake without excess fat. The calories that are present primarily come from the fish's natural protein. For example, a 5-ounce can may contain over 20 grams of high-quality protein. This high protein-to-calorie ratio can promote satiety, helping you feel full for longer and potentially reducing overall calorie consumption throughout the day.

Canned Tuna Nutrition Comparison

To highlight the key differences, here is a comparison table for a 5-ounce can of tuna, drained. Figures are approximate and can vary by brand.

Nutrient Water-Packed Tuna (approx.) Oil-Packed Tuna (approx.)
Calories 120 kcal 280 kcal
Total Fat 1 g 13 g
Protein 25 g 23 g
Omega-3s Present (may be lower) Present (absorbed into oil)
Vitamin D Present Present (may be higher due to oil)
Selenium Present Present
Sodium 300-400 mg (varies) 300-400 mg (varies)

The Health Implications of Your Choice

Your choice between water and oil packed tuna depends on your dietary goals. Both are nutritious, but they serve different purposes. The oil-packed version offers more flavor and a moister texture, but it also contains significantly more calories. The water-packed version is a much leaner option, ideal for low-calorie diets, while still delivering high-quality protein and omega-3 fatty acids.

How to Choose the Healthiest Canned Tuna

Making an informed decision about your canned tuna involves more than just looking at the calorie count. Consider your specific health goals and preferences.

  • For weight management: Water-packed tuna is the clear winner. Its low-calorie, high-protein profile supports weight loss efforts by increasing satiety.
  • For flavor and moisture: If calories aren't a primary concern, oil-packed tuna offers a richer flavor and is excellent for recipes where the added moisture is beneficial, such as salads or pasta dishes.
  • For mercury concerns: Regardless of packing liquid, consider the type of tuna. Light or skipjack tuna typically has lower mercury levels than white or albacore tuna.
  • For sodium control: Canned tuna can be high in sodium. Look for "no salt added" or "low sodium" varieties to keep your intake in check.
  • For sustainable sourcing: Check for certifications like the Marine Stewardship Council (MSC) label to ensure the tuna was sustainably sourced.

Conclusion: A Matter of Preference and Purpose

The short answer to "is canned tuna high in calories?" is that it depends on the preparation. While tuna itself is a lean protein, the added oil in some cans dramatically increases the calorie count. Water-packed tuna is a low-calorie, high-protein option perfect for weight management. Oil-packed tuna, while higher in calories, offers a richer flavor and more moisture. By understanding these key differences, you can make the best choice for your dietary needs and health goals.

Practical Ways to Incorporate Canned Tuna

Here are some simple and nutritious ways to include canned tuna in your meals:

  • Tuna Salad: A classic for a reason. Combine drained, water-packed tuna with Greek yogurt or a light mayonnaise for a lower-calorie, high-protein salad.
  • Tuna Pasta: Mix oil-packed tuna with fresh tomatoes, capers, and herbs for a flavorful, Mediterranean-style pasta dish.
  • Tuna Patties: Combine water-packed tuna with breadcrumbs, egg, and seasoning to form patties. Pan-fry or bake for a quick meal.
  • Stuffed Tomatoes: Hollow out tomatoes and fill them with a mixture of water-packed tuna, diced celery, and a light dressing.
  • Tuna Wraps: Use whole-wheat tortillas and fill them with tuna salad and plenty of fresh, crisp lettuce.

How to Maximize Nutrition and Minimize Calories

By being mindful of how you prepare and serve canned tuna, you can easily control the calorie content.

  1. Drain it well: Always drain oil-packed tuna thoroughly to remove excess fat and calories. For water-packed tuna, draining is also a good practice.
  2. Choose healthy add-ins: Instead of high-fat mayonnaise, use Greek yogurt, mustard, or avocado for creaminess in tuna salad.
  3. Load up on veggies: Incorporate plenty of chopped vegetables like celery, onions, and bell peppers to add volume and nutrients without extra calories.
  4. Pair with healthy carbs: Serve tuna over a bed of greens or with whole-grain crackers instead of high-calorie white bread.

Frequently Asked Questions

Yes, canned tuna, especially water-packed varieties, is excellent for weight loss. It is low in calories and high in protein, which helps increase feelings of fullness and can reduce overall calorie intake.

For calorie control, tuna packed in water is the healthier option. While tuna in olive oil can provide beneficial fats, the water-packed version is significantly lower in fat and calories.

The calorie count varies significantly based on how it's packed. A 5-ounce can of tuna in water has about 120 calories, while the same size can in oil can have approximately 280 calories or more.

Yes, draining the oil from canned tuna removes a large portion of the added fat and, consequently, a significant number of calories. However, some oil will still be absorbed into the tuna, so it will still be higher in calories than water-packed tuna.

While canned tuna is nutritious, eating it daily is not recommended due to potential mercury exposure. It's best to vary your protein sources and follow guidelines for consumption, especially with albacore tuna, which is higher in mercury.

Canned light tuna (skipjack) packed in water has the lowest calorie count, and it also contains less mercury than white (albacore) tuna.

The protein content is very similar in both types. The primary nutritional difference is in the fat and calorie content from the added oil.
