Protein Content: A Direct Comparison
When evaluating which shellfish offers more protein, the numbers show that shrimp has a slight advantage. A standard 100-gram serving of cooked shrimp contains approximately 22.7 grams of protein. In contrast, the same 100-gram serving of scallops provides around 20.5 grams of protein. While the difference is not substantial enough to make or break a diet, shrimp does come out on top in a direct, weight-for-weight comparison.
Nutritional Breakdown Beyond Protein
Beyond protein, both shrimp and scallops offer a variety of other important nutrients, while differing in their overall nutritional profile. This is where your choice may depend on specific dietary goals.
Shrimp's Profile:
- Calories: Approximately 119 kcal per 100g.
- Carbohydrates: Very low, at only 1.52 grams per 100g.
- Fats: Minimal, with around 1.7 grams per 100g.
- Key Nutrients: A rich source of iodine, which is critical for thyroid health, and contains the antioxidant astaxanthin, beneficial for heart and brain health. Shrimp also provides phosphorus and choline.
Scallops' Profile:
- Calories: Slightly lower than shrimp, at approximately 111 kcal per 100g.
- Carbohydrates: Higher than shrimp, containing 5.41 grams per 100g.
- Fats: Extremely low, with only 0.84 grams per 100g.
- Key Nutrients: Rich in magnesium and potassium, both of which support cardiovascular health by helping to lower blood pressure. Scallops are also an excellent source of vitamin B12.
Health Benefits of Shrimp and Scallops
Incorporating either shellfish into your diet can offer significant health advantages, as both are nutrient-dense options.
Benefits of Shrimp
- Supports Thyroid Health: Shrimp is one of the best dietary sources of iodine, a mineral essential for proper thyroid function.
- Provides Antioxidant Protection: The carotenoid astaxanthin, which gives shrimp its reddish color, has been studied for its ability to reduce inflammation and protect against cell damage.
- Promotes Brain Health: Astaxanthin's anti-inflammatory properties may also protect brain cells and support cognitive function.
- Aids in Weight Management: As a low-calorie, high-protein food, shrimp can help you feel full and satisfied, aiding in weight loss efforts.
Benefits of Scallops
- Supports Cardiovascular Health: The high content of magnesium and potassium in scallops helps regulate blood pressure and improve blood flow, promoting overall heart health.
- Boosts Energy and Metabolism: Scallops are a potent source of vitamin B12, which is crucial for nerve function, red blood cell production, and energy metabolism.
- Builds Muscle and Promotes Satiety: With a protein content comparable to shrimp, scallops are an effective food for muscle growth and maintenance, keeping you feeling full for longer.
Cooking Considerations for Shrimp and Scallops
The primary difference in preparation lies in their texture and flavor profile. Scallops are tender and sweet and cook very quickly, often requiring just a quick sear or pan-fry. This makes them a great option for a fast, elegant meal. In contrast, shrimp has a firmer texture and a milder flavor, making it incredibly versatile for use in pasta dishes, stir-fries, salads, and more. Be mindful of added fats like butter or oil during cooking, as this can change the overall nutritional profile of an otherwise lean protein.

Conclusion: Choosing the Right Shellfish for You
When it comes to the question, "is shrimp or scallops higher in protein?", shrimp is the technical winner, albeit by a small margin. However, both shellfish are exceptional choices for a healthy, high-protein diet. Your decision may ultimately come down to taste, texture preference, and other nutritional goals. If you're seeking higher iodine levels and powerful antioxidants, shrimp is a great choice. If you're prioritizing heart-healthy minerals like magnesium and potassium, scallops may be a better fit. Both are versatile, low-calorie, and delicious options to add to a balanced eating plan.
