The Core Calorie Count
For individuals tracking their intake, knowing the precise nutritional information of common foods is essential. The consensus among multiple food databases confirms that a 100-gram serving of canned light tuna in water, after being properly drained, provides roughly 116 calories. This figure can vary slightly by brand, but it serves as a reliable benchmark for meal planning. The primary source of these calories is the tuna's high protein content, while the fat and carbohydrate contributions are very low.
Macronutrient Breakdown in 100g
Beyond the calorie count, it's beneficial to understand where those calories come from. The macronutrient distribution is what makes canned tuna in water such a popular and healthy choice.
- Protein: Expect around 26 grams of protein in a 100g serving. This makes up the vast majority of its caloric value. As an excellent source of complete protein, it provides all the essential amino acids needed for muscle repair and growth.
- Fat: The fat content is minimal, typically around 1 gram per 100g serving. This is one of the key differences when compared to tuna packed in oil, which contains significantly more fat and therefore more calories.
- Carbohydrates: Canned tuna in water is virtually carbohydrate-free. This makes it an ideal food for people following ketogenic, low-carb, or zero-carb diets.
Water vs. Oil: A Calorie Comparison
The way tuna is canned has a major impact on its final nutritional profile. Canned tuna packed in oil is the most common alternative and presents a significant caloric difference that is important to consider.
| Nutrient (per 100g, drained) | Canned Tuna in Water | Canned Tuna in Oil |
|---|---|---|
| Calories | ~116 kcal | ~159-192 kcal |
| Protein | ~26g | ~24g |
| Fat | ~1g | ~6.4g |
| Carbohydrates | 0g | 0g |
As the table shows, tuna packed in oil can have up to 50% more calories due to the added fat. If you are aiming for the lowest possible calorie count, consistently choosing tuna packed in water is the right decision.
Beyond Calories: A Rich Nutrient Profile
Canned tuna isn't just about protein and low calories; it also delivers a host of other beneficial nutrients. A 100g serving provides a range of vitamins and minerals important for overall health.
- Vitamin B12: An excellent source, with a 100g serving providing over 100% of the recommended daily value.
- Selenium: Tuna is rich in selenium, a powerful antioxidant that protects the body from damage caused by free radicals.
- Niacin (Vitamin B3): A good source of niacin, which supports healthy skin, digestion, and nerve function.
- Omega-3 Fatty Acids: While tuna in oil has more total fat, tuna in water still provides some beneficial omega-3s, particularly DHA.
Tips for Maximizing Your Canned Tuna Experience
To get the most out of your canned tuna while keeping it healthy, consider these preparation tips:
- Always drain thoroughly: Draining removes the excess water and any added salt, which can significantly reduce the sodium content.
- Use healthy mixers: Instead of high-calorie mayonnaise, try mixing tuna with Greek yogurt, hummus, or avocado for a creamy texture with added nutrients.
- Incorporate it into salads: Flake the tuna over a bed of fresh greens, vegetables, and a light vinaigrette for a quick, protein-packed lunch.
- Make low-carb snacks: Create tuna patties or use it as a filling for lettuce wraps.
