What Has More Protein, Salmon or Sardines? A Full Nutritional Breakdown

According to nutritional data, per 100 grams, sardines provide slightly more protein than salmon. However, the choice between these two nutritional powerhouses goes far beyond a simple protein count and depends heavily on your overall dietary goals and preferences.

Quick Summary

A comparison of salmon and sardines reveals that sardines typically contain a slightly higher protein content per 100g, while also offering more calcium and vitamin B12. Salmon provides more vitamin D and is generally lower in calories and cholesterol. The optimal choice depends on specific dietary needs and how the fish is prepared.

Key Points

• Sardines Offer More Protein: Per 100g, sardines typically contain about 24.6g of protein compared to salmon's ~22.1g.

• Sardines are Calcium Rich: Canned sardines, including the edible bones, are a phenomenal source of calcium, offering a significant boost to bone health.

• Salmon Excels in Vitamin D: Salmon contains substantially more vitamin D per serving compared to sardines, which is essential for calcium absorption and immune support.

• Sardines Offer More B12: Sardines provide nearly three times the amount of vitamin B12 found in salmon, crucial for nerve function.

• Mercury Levels Differ: Due to their smaller size, sardines contain lower levels of mercury than salmon, making them a safer choice for frequent consumption.

• Cooking Method Matters: The canning process for sardines can introduce higher sodium and cholesterol levels, depending on the packing liquid.

• Best to Include Both: For a comprehensive range of nutrients, incorporating both sardines and salmon into a balanced diet is recommended.

Protein Showdown: A Gram-for-Gram Look

While both salmon and sardines are celebrated for their high protein content, a direct comparison per 100g serving shows a clear winner. Sardines, particularly when canned and drained, often contain around 24.6 grams of protein, edging out salmon, which typically offers about 22.1 grams. This makes the smaller sardine a more concentrated source of protein on a gram-for-gram basis. For those seeking to maximize protein intake in a smaller portion, sardines present a compelling case.

Beyond the Protein: A Deeper Nutritional Analysis

While protein is often the main consideration, the true value of these fatty fish lies in their broader nutritional profiles. They are rich in various vitamins, minerals, and essential fatty acids that contribute to overall health. It's crucial to look at the complete picture to decide which fish best fits your diet.

Comparison Table: Salmon vs. Sardines (per 100g serving)

Nutrient	Sardines (Canned in Oil)	Salmon (Cooked)	Notes
Protein	~24.6 g	~22.1 g	Sardines have a slight edge in protein content.
Calories	~208 kcal	~142 kcal	Salmon is the lower-calorie option per serving.
Fat	~11.4 g	~12.4 g	Both are rich in healthy fats, with salmon being slightly higher.
Omega-3s	Higher	High	Sardines generally offer more omega-3s per serving.
Vitamin D	193 IU	546 IU	Salmon is a significantly better source of vitamin D.
Vitamin B12	8.94 mcg	2.8 mcg	Sardines contain nearly triple the amount of vitamin B12.
Calcium	High (~382 mg)	Low (~15 mg)	Sardines, eaten with bones, provide a huge calcium boost.
Cholesterol	~142 mg	~63 mg	Sardines contain more than twice the cholesterol.
Sodium	Higher, varies by canning	Lower	Canned sardines can have added sodium.

Health Benefits of Salmon and Sardines

Both salmon and sardines are excellent additions to a heart-healthy diet, largely due to their rich content of omega-3 fatty acids, particularly EPA and DHA. However, their distinct nutritional profiles offer unique advantages:

The Allure of Sardines: Calcium, B12, and Omega-3s

• Exceptional Source of Calcium: As small, whole fish, canned sardines offer a significant amount of calcium from their edible bones. This is particularly beneficial for those who do not consume dairy. A single 3.75-ounce can can provide up to 35% of the daily value.
• Vitamin B12 Powerhouse: Sardines are a stellar source of vitamin B12, which is crucial for nerve function and red blood cell formation. A serving contains several times the recommended daily intake.
• High Omega-3 Content: Gram for gram, canned sardines often pack more omega-3 fatty acids than salmon. These essential fats are known for their anti-inflammatory effects and support for brain and heart health.

The Advantages of Salmon: Vitamin D and Overall Versatility

• Superior Vitamin D Source: Salmon is one of the few natural dietary sources of vitamin D, and it offers significantly more per serving than sardines. Vitamin D is vital for calcium absorption, bone health, and immune function.
• Versatile and Mild Flavor: Salmon's milder taste and larger fillet size make it incredibly versatile for cooking. It's often preferred for grilling, baking, or pan-searing, whereas the distinct flavor of sardines can be an acquired taste for some.
• Lower in Sodium and Cholesterol: While both are healthy, a piece of cooked salmon typically has less sodium and substantially less cholesterol than a serving of canned sardines, an important consideration for people with certain health conditions.

Making Your Choice

Your decision between salmon and sardines may come down to your specific health goals, cooking style, and budget. If you're aiming to maximize calcium and B12 intake or prefer a more budget-friendly option, sardines are an excellent choice. Their higher omega-3 content per ounce is another major plus. They can be enjoyed simply on crackers, in salads, or mashed into a paste.

On the other hand, if you're focusing on boosting your vitamin D intake, prefer a milder flavor, or need a lower-cholesterol protein source, salmon is the clear winner. Its culinary versatility makes it a staple for many healthy diets. Wild-caught salmon is generally recommended to minimize contaminants, but farmed salmon is still a very healthy and accessible option.

The Final Verdict

While sardines technically offer more protein per 100g, calling one definitively 'better' than the other is misleading. Both fish provide a unique and valuable set of nutrients. The best approach for most people is to include both in their diet. Sardines can be a quick, nutrient-dense snack, while salmon can serve as a more substantial centerpiece for a meal. By incorporating both, you can enjoy a wider array of health benefits and diversify your intake of essential vitamins and minerals. Consider fresh or low-sodium canned options for the healthiest results.

How to Incorporate Them Into Your Diet

• Sardines: Add canned sardines (in olive oil or water) to toast with lemon and herbs, mix them into pasta with garlic and capers, or mash them with avocado for a protein-packed spread.
• Salmon: Bake or grill salmon fillets with asparagus, add smoked salmon to a bagel with cream cheese, or flake cooked salmon into a salad for a healthy, satisfying meal.

Conclusion

In the contest of which has more protein, salmon or sardines, the smaller fish takes the prize on a gram-for-gram basis. However, their nutritional stories are far more complex. Sardines are superior for calcium and vitamin B12, while salmon provides more vitamin D and is lower in cholesterol. Ultimately, both are highly nutritious, and the best choice is often to enjoy both as part of a balanced and varied diet.
