🎣 The Seafood Lover's Dilemma

Tasty? ✓ Healthy? ✓ But how many calories are swimming in there? This is where our Seafood Nutrition Calculator comes to your rescue. Why guessing your salmon's fat content is like fishing blindfolded — you might occasionally get lucky, but you'll mostly miss the mark. With precise nutritional data at your fingertips, you can make informed decisions about every seafood dish you prepare.

🌊 The Ocean on Your Plate: Types of Seafood

🐟 Fish Fiesta

From salmon to sardines, fatty fish are nutritional powerhouses. These species are packed with omega-3 fatty acids that make your heart do the mermaid dance. Whether you prefer wild-caught tuna or farm-raised tilapia, each variety offers unique nutritional benefits. Our calculator covers all the popular options to help you choose based on both taste and nutrition.

🦀 Shellfish Showdown

Crabs, lobsters, and shrimp galore — these crustaceans are surprisingly lean yet protein-rich. Shrimp especially stands out as an incredibly low-calorie, high-protein option. They're also rich in selenium and antioxidants. Battle of the shell dwellers has never been easier to compare with our detailed breakdowns.

🦪 The Mollusk Mystery

Clams, oysters, and squid stats reveal interesting patterns. Oysters are particularly famous for their zinc and selenium content, while squid offers a unique nutrient profile. These options are perfect for adventurous eaters looking to diversify their seafood intake.

🌿 Seaweed Surprise

Don't overlook the ocean's garden! Seaweed snacks and nori sheets offer concentrated nutrients with minimal calories. They're excellent sources of iodine and other trace minerals essential for thyroid health.

🔬 Deep Dive into Nutrients: What We Measure

💪 Protein Powerhouses

Why fish flex harder than chicken? Fish provides complete proteins with all nine essential amino acids while being lower in fat than red meat. Tuna leads the pack with 28g per 100g serving, making it a muscle-builder's dream.

❤️ Fatty Acids

Omega-3 fatty acids that make your heart feel great. DHA and EPA — sounds fancy, but they're just brain food. These polyunsaturated fats reduce inflammation, support cognitive function, and promote heart health. Mackerel and salmon are omega-3 royalty.

🌟 Vitamin Treasure Chest

Vitamins A, B12, D, and beyond. Seafood is one of the few natural sources of Vitamin D, crucial for bone health and immune function. B12 keeps your energy levels high, while Vitamin A supports eye health.

🧂 The Sodium Sea

Fresh seafood contains minimal sodium, but processed varieties (like canned tuna) can be higher. Be mindful of added salt during preparation.

💛 Cholesterol Currents

The truth about seafood and heart health: yes, seafood contains cholesterol, but it's the dietary fiber and omega-3s that matter more for overall heart health. Modern research shows that shrimp doesn't raise cholesterol as much as previously thought.

⚔️ Calorie Comparisons: Who's the Biggest Catch?

🍳 Fried vs. Grilled

How cooking methods change the numbers dramatically. Grilled salmon stays at 206 kcal per 100g, but when breaded and deep-fried, it can jump to 320+ kcal. Always prefer baking, grilling, or steaming for maximum nutrition retention.

🚫 Myths That Need Deboning

Myth 1: "Seafood Has No Fat"

❌ False! Tell that to salmon. Fatty fish like salmon, mackerel, and sardines contain 10-25g of fat per 100g serving. The good news? Most of it is heart-healthy omega-3 fat, which is actually beneficial.

Myth 2: "Shrimp Raises Cholesterol"

❌ Not as much as you think. While shrimp does contain cholesterol (195mg per 100g), it's very low in saturated fat and rich in antioxidants. Modern research shows it doesn't significantly impact blood cholesterol levels.

Myth 3: "Frozen Fish Has Fewer Nutrients"

✓ Cold truth revealed: frozen fish actually retains more nutrients than "fresh" fish that's been sitting on display counters. Flash-freezing locks in nutrients at their peak. Buy frozen with confidence!

Myth 4: "Canned Tuna Loses Its Omega-3s"

✓ Mostly true, it retains most of its nutrients. The canning process doesn't significantly destroy omega-3s. However, choose low-sodium varieties and drain the oil to reduce sodium and extra calories.

⚠️ Mercury Rising: When "Healthy" Fish Turn Toxic

High-Mercury Culprits to Monitor

• Shark, Swordfish, King Mackerel: Limit to 1-2 times per month
• Tilefish, Bigeye Tuna: Reserve for special occasions only
• Large predatory fish: Accumulate more mercury over their lifetime

Low-Mercury Heroes

• Salmon, Sardines, Anchovies: Safe to eat 2-3 times per week
• Cod, Flounder, Tilapia: All excellent low-mercury options
• Shrimp, Oysters: Among the safest shellfish choices

Balancing benefits vs. risks — no tinfoil hats required. The benefits of eating seafood far outweigh the risks for most people, especially when you rotate between low-mercury varieties.

💪 Fitness Fishermen: Seafood for Goals

For Weight Loss

Counting smarter, not hungrier. Lean proteins fill you up on fewer calories. A 150g serving of cod (about 123 kcal) with vegetables provides incredible satiety compared to 123 kcal of carbs alone. The thermic effect of protein means your body burns more calories digesting it.

For Muscle Gain

Protein timing: pre- and post-workout seafood secrets. Tuna and salmon are perfect post-workout meals with complete amino acid profiles. A 200g portion of tuna provides 56g of protein — nearly a full day's requirement for many people.

Real-World Examples

• Weight Loss: 150g grilled cod (123 kcal) + vegetables = full meal under 200 kcal
• Muscle Gain: 200g salmon (412 kcal) + sweet potato + greens = perfect post-workout
• Maintenance: 175g shrimp stir-fry balances calories with high satiety

🌍 The Green Tide: Sustainable Seafood

Eco-Friendly Options That Keep the Ocean Happy

Sustainable seafood choices matter for future generations. Look for MSC (Marine Stewardship Council) certification, which indicates responsibly-managed fisheries.

Farmed vs. Wild

• Wild-caught: Generally more nutrient-dense, higher omega-3s, no antibiotics
• Farm-raised: More sustainable for population demands, often higher in omega-6s
• Best practice: Rotate between both and check sourcing labels

The numbers really say: both options contribute to your nutrition goals. Choose based on availability, budget, and sustainability concerns in your region.
