The Blue Swimmer Crab (Portunus pelagicus), commonly known as Rajungan, is a highly prized seafood delicacy known for its sweet, tender meat and savory flavor. Unlike mud crabs that live in mangroves, Blue Swimmer Crabs live exclusively in the sea, resulting in a leaner texture and a distinct nutritional profile.

A. Nutritional Composition
Blue Swimmer Crab is an excellent source of high-quality animal protein. A 100-gram serving of crab meat contains various essential nutrients:

| Nutrient | Primary Benefit |
  1. High Protein
    • Builds and repairs muscle tissues
  2. Omega-3 Fatty Acids
    1. Supports heart health and brain function
  3. Vitamin B12
    • Prevents anemia and maintains the nervous system
  4. Zinc
    • Boosts the immune system and speeds up wound healing
  5. Selenium
    • Acts as a powerful antioxidant to fight free radicals
  6. Phosphorus & Calcium
    • Maintains bone density and dental health
B. Health Benefits
When consumed in moderation, Blue Swimmer Crab provides several significant health advantages:
  • Promotes Heart Health: The Omega-3 content helps lower LDL (bad cholesterol) levels and reduces inflammation in the blood vessels.
  • Enhances Brain Function: Essential fatty acids are crucial for cognitive health, improving memory and concentration.
  • Prevents Anemia: High levels of Iron and Vitamin B12 play a vital role in the production of healthy red blood cells.
  • Strengthens Immune System: Rich in Zinc, it helps the body defend itself against viral and bacterial infections.
  • Supports Growth and Development: The high-quality protein is essential for children and adolescents for muscle and cell development.
C. Side Effects and Precautions
Despite its benefits, there are certain risks to consider:
  • High Cholesterol & Purines: People with Gout (high uric acid) or existing high cholesterol should limit intake, as it can trigger flare-ups.
  • Allergic Reactions: Shellfish allergies are common. Symptoms may include itching, swelling, or in severe cases, respiratory distress.
  • Sodium Content: Crabs naturally contain salt. Those with hypertension should be careful not to add excessive salt during cooking.
D. Best Preparation Methods
for Optimal Results
To maximize nutrient retention without adding unnecessary calories, follow these tips:

Selection Tips
Choose fresh crabs. They should have a clean, salty ocean scent (not a pungent fishy smell), a firm shell, and feel heavy for their size.

Healthy Cooking Techniques
  • Steaming: This is the gold standard. Steaming preserves the natural sweetness and nutrients without adding saturated fats.
  • Boiling: Boil with slices of ginger or lemongrass to eliminate any "fishy" odor. Avoid overcooking to keep the meat tender.
  • Avoid Deep Frying: Frying or using heavy, sugary sauces (like excessive instant chili sauces) can negate the nutritional benefits.
Pro-Tip
Squeeze fresh lime or lemon juice over the meat before eating. The Vitamin C helps your body absorb the iron from the crab more efficiently.
