Discovering the Highest Protein Seafood
When it comes to boosting protein intake, seafood is an excellent choice, offering a complete and high-quality source of this essential macronutrient. Different types of seafood offer varying protein levels, along with a range of other valuable nutrients. While many assume fish like salmon are the top contenders, some lesser-known options may surprise you with their protein density. Choosing the best seafood depends on your specific health goals, including muscle building, weight management, or heart health.
Octopus and Tuna: The Top Contenders
Interestingly, fresh tuna and octopus often vie for the top spot as the most protein-rich seafood. Fresh tuna, particularly yellowfin, can offer a robust 30.7 grams of protein per 100-gram serving. However, some sources also cite octopus as a powerhouse, providing nearly 30 grams of protein per 100 grams, making it a serious challenger. While these two frequently top the charts, several other fish and shellfish offer impressive protein content worth considering.
Other Protein-Packed Fish and Shellfish
Beyond the leading contenders, many other types of seafood provide substantial protein content:
- Anchovies: Despite their small size, anchovies pack a significant punch, with nearly 29 grams of protein per 100 grams, especially when canned. They are also rich in omega-3 fatty acids, though typically higher in sodium.
- Sardines: These small, oily fish offer up to 28 grams of protein per 100 grams, along with high levels of omega-3s, vitamin D, and calcium. They are also a budget-friendly option.
- Trout: With around 26.6 grams of protein per 100 grams, trout is a delicious and lean option that is also low in mercury.
- Scallops: A fantastic source of lean protein, scallops provide about 24 grams of protein per 100-gram serving. They are also rich in minerals like magnesium and potassium.
- Crab: Crab meat contains about 17 to 19 grams of protein per 100-gram serving and is low in fat, while being rich in vitamins and minerals like zinc and copper.
Comparing Protein Content: Fish vs. Shellfish
While fish like tuna and salmon are widely recognized for their protein content, shellfish offers an equally valuable protein source, often with fewer calories and saturated fat. For example, shrimp, scallops, and crab are excellent additions to a healthy, balanced diet. The key is to consume a variety of both fish and shellfish to ensure a broad spectrum of nutrients, from heart-healthy omega-3s to vital minerals.

Preparing Seafood for Maximum Health Benefits
How you prepare seafood can significantly impact its overall health profile. To retain its lean protein and nutritional value, opting for preparation methods like grilling, baking, or steaming is best. Frying or preparing seafood in heavy, butter-based sauces can add unnecessary fat and calories. Simple seasonings like lemon, garlic, and fresh herbs can enhance flavor without compromising health. For convenience, canned seafood like tuna and sardines can be a quick and easy way to add protein to meals, just be mindful of added sodium.
Potential Health Concerns: A Balanced Perspective
While seafood is a nutritious protein source, it is important to be aware of potential health concerns, primarily concerning mercury levels. Larger, longer-living predatory fish like certain tuna and swordfish can accumulate higher mercury levels. Health experts advise limiting consumption of these fish, particularly for pregnant women and young children. Choosing smaller fish like sardines and trout, or ensuring varied seafood consumption, can help mitigate these risks. Sustainability is another factor to consider, with many organizations providing resources to help consumers choose responsibly sourced seafood.
Conclusion: Making the Right Seafood Choice
Ultimately, the question of what is the most protein-rich seafood depends on how you measure it. While fresh tuna and octopus often lead in protein grams per serving, other options like anchovies and sardines offer dense protein and additional benefits like omega-3s and calcium. For those prioritizing lean, clean protein with minimal fat, choices like cod, scallops, and tilapia are excellent. By incorporating a variety of seafood into your diet and preparing it healthily, you can enjoy a wide array of flavors and nutritional benefits that support muscle growth, heart health, and overall wellness.
