The Caloric Truth: How many calories are in shrimp?
For anyone monitoring their calorie intake, shrimp is an excellent choice. The number of calories in shrimp depends heavily on its size and, more importantly, how it's prepared. A raw, 3-ounce (85-gram) serving has roughly 60 calories, while the same amount cooked has slightly more due to the concentration of nutrients as water is lost. Specifically, 100 grams of cooked shrimp contains around 99 calories, a testament to its lean profile. A typical 3-ounce serving of cooked, plain shrimp is often cited as having about 84 to 101 calories.
The bulk of shrimp's calories come from its high-quality protein content, with minimal fat and carbohydrates, making it a satiating option that helps with weight management. The nutritional value is significant, providing more than nine essential vitamins and minerals per serving.
Calorie Breakdown by Preparation Method
Your cooking choice can be the difference between a light, healthy meal and a calorie-dense one. Simple preparation methods like steaming, boiling, or grilling maintain shrimp's low-calorie nature, while frying can more than double the caloric value.
- Boiled or steamed: A 3-ounce serving is typically 84–90 calories. This method preserves nutrients and adds no extra fats.
- Grilled: A 3-ounce serving is 85–95 calories, with a minimal amount of oil for flavor. Using a cooking spray instead of a heavy brush of oil can further reduce calories.
- Fried: A 3-ounce serving can jump to 200–250 calories. This is because the batter and oil used in frying add substantial fat and carbohydrates.
- Shrimp Scampi: Often made with large amounts of butter and oil, this dish's calorie count can quickly become significant. Opting for a smaller amount of heart-healthy olive oil and plenty of garlic and herbs can reduce the impact.
Shrimp vs. Other Proteins: A Nutritional Comparison
| Food (3-ounce cooked serving) | Calories (approximate) | Protein (approximate) | Saturated Fat (approximate) | Cholesterol (approximate) |
|---|---|---|---|---|
| Shrimp (boiled) | 85-90 | 20 g | <1 g | 130 mg |
| Chicken Breast (grilled) | 128 | 26 g | <1 g | 73 mg |
| Salmon (farmed, grilled) | 175 | 19 g | 2.5 g | 52 mg |
| Ground Beef (85% lean) | 215 | 22 g | 5 g | 75 mg |
This comparison table illustrates that shrimp, when cooked healthily, is highly competitive with other lean protein sources in terms of calories and saturated fat, despite its higher cholesterol content.
Beyond Calories: Other Nutritional Highlights
While the low-calorie count is a major draw, shrimp offers a host of other nutritional benefits:
- High-Quality Protein: Shrimp is a fantastic source of lean protein, which is vital for building and repairing tissues, producing enzymes and hormones, and maintaining a healthy immune system. The protein in shrimp is considered high-quality and contains all essential amino acids.
- Vitamins and Minerals: A serving of shrimp provides more than nine different vitamins and minerals. This includes B vitamins like B12, which is crucial for nerve function and energy production. It also contains selenium, a powerful antioxidant that supports thyroid and immune health, and iodine, essential for metabolic regulation.
- Antioxidants: Shrimp contains astaxanthin, a carotenoid antioxidant that has anti-inflammatory properties and may help protect against certain diseases.
- Omega-3 Fatty Acids: While not as rich in omega-3s as fatty fish like salmon, shrimp still contains beneficial polyunsaturated fatty acids that support heart health.
Health Considerations: Cholesterol and Sodium
For many years, shrimp's high dietary cholesterol was a cause for concern. However, recent research suggests that dietary cholesterol has a much smaller impact on blood cholesterol levels than saturated and trans fats. Shrimp is very low in saturated fat, and studies have shown that it can actually increase HDL ('good') cholesterol while supporting a healthy ratio of HDL to LDL cholesterol.
Sodium is a more valid concern, especially with processed or pre-seasoned shrimp. Raw shrimp naturally contains some sodium, but frozen shrimp or those prepared in a brine solution can have significantly higher levels. It's best to choose plain, raw or frozen shrimp and season it yourself to control the sodium content.
Sustainable Sourcing for a Healthier Planet
When purchasing shrimp, considering sustainability is an important step. Look for certification labels from organizations like the Aquaculture Stewardship Council (ASC) or the Marine Stewardship Council (MSC) to ensure the shrimp was harvested responsibly. This supports ethical fishing practices and helps protect marine ecosystems.
Healthy Ways to Enjoy Shrimp
To make the most of shrimp's nutritional benefits while keeping calories in check, consider these simple preparations:
- Shrimp skewers: Toss with a little olive oil, lemon, and your favorite spices, then grill or bake until pink.
- Shrimp cocktail: The classic low-calorie appetizer. Serve with a simple, tomato-based sauce.
- Stir-fried shrimp: Sauté with plenty of vegetables and a light sauce. Use a non-stick pan to minimize the oil needed.
- Shrimp salad: Combine chilled, boiled shrimp with Greek yogurt or a light vinaigrette for a fresh meal.
- Shrimp and veggie pasta: Use a spiralizer to create veggie noodles or opt for a whole-wheat pasta and a light garlic and herb sauce.
Conclusion
Shrimp is an incredibly versatile and healthy protein source. Its low-calorie, high-protein profile, along with its abundance of essential vitamins and minerals, makes it an excellent addition to almost any diet. While it contains dietary cholesterol, the low saturated fat content means it doesn't negatively impact blood cholesterol for most people. The key to keeping shrimp a nutritious part of your diet lies in the cooking method—prioritizing simple, healthy preparations like boiling, steaming, and grilling over high-fat options like frying ensures you reap all the benefits without adding unnecessary calories. By being mindful of preparation and ingredients, you can enjoy shrimp as a delicious and nutrient-rich part of a healthy lifestyle.

Cooking Methods That Keep It Lean
- Boiling and Steaming: These methods are perfect for maintaining shrimp's natural flavor and keeping the calorie count low. Use water or a court-bouillon for maximum flavor infusion.
- Grilling and Broiling: A quick way to get a smoky, seared exterior with minimal fat. Lightly brush with olive oil and season with lemon and spices.
- Sautéing: Use a non-stick pan and just a touch of heart-healthy oil, like olive or avocado oil, to cook quickly with vegetables.
- Air-Frying: A healthier alternative to deep-frying, air-frying can give you a crispy texture without excess oil and calories.
- Oven Baking: Sheet pan meals with shrimp and vegetables tossed in a light seasoning are a simple and clean way to cook shrimp.
