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.

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.
