Crab Cuisine: Unraveling the Nutritional Treasure and Suitability for Consumption


Crabs, with their intriguing appearance and mouth-watering taste, have been a favourite delicacy for seafood enthusiasts around the world. However, there is often confusion regarding their classification as fish or shellfish and concerns about their nutritional value and suitability for consumption. In this blog post, we will delve into the world of crabs, explore their categorization, and nutritional benefits, and identify who should approach this delectable treat with caution.

I. Categorization: Fish or Shellfish?

Crabs belong to the crustacean family, making them part of the shellfish category. While they do live in water, like fish, their biology and characteristics differ significantly. Crabs possess a hard exoskeleton, five pairs of legs (including one pair of claws), and a unique sideways walking style, setting them apart from true fish species. Consequently, they are considered shellfish, alongside lobsters, shrimps, and crayfish.

II. Nutritional Value of Crab

  1. Protein Powerhouse: Crabs are an excellent source of high-quality protein, making them a valuable dietary option for muscle building and repair. A 3-ounce serving of crab typically contains around 17 grams of protein.
  2. Low in Calories and Fat: Crab is an ideal choice for health-conscious individuals as it is relatively low in calories and saturated fat. A 3-ounce serving of crab provides only about 90 calories and 1 gram of fat.
  3. Rich in Essential Nutrients: Crab is a good source of essential nutrients such as selenium, vitamin B12, copper, and phosphorus. Selenium is an antioxidant that supports the immune system, while vitamin B12 is vital for nerve function and DNA synthesis.
  4. Omega-3 Fatty Acids: Crabs contain omega-3 fatty acids, known for their heart-healthy benefits. These fatty acids play a role in reducing inflammation and supporting cardiovascular health.

III. Is Crab a Good Food to Take?

Crab is a good food to include in your diet, given its impressive nutritional profile. It provides valuable nutrients without excessive calories or unhealthy fats. Moreover, it offers a unique and delicious culinary experience that can be enjoyed in various dishes, from crab cakes to crab salads and stir-fries.

IV. Who Should Avoid Eating Crab?

While crab is a nutritious and flavoursome food choice for most people, there are certain individuals who should exercise caution or avoid its consumption:

  1. Allergic Reactions: People with shellfish allergies must steer clear of crabs and other shellfish as it can trigger severe allergic reactions, ranging from mild itching to life-threatening anaphylaxis.
  2. Gout Sufferers: Crab contains purines, which can elevate uric acid levels in the body and trigger gout attacks. Individuals prone to gout should limit their intake or seek medical advice.
  3. High Cholesterol Concerns: While crab is relatively low in saturated fat, those with high cholesterol levels should consume it in moderation as part of a balanced diet.
  4. Mercury Sensitivity: Pregnant or nursing women, young children, and individuals sensitive to mercury should avoid excessive consumption of certain crab species that may contain higher mercury levels.


In summary, crab is a delightful and nutritious seafood option that falls under shellfish. Packed with essential nutrients, low in calories and saturated fat, and offering a delectable taste, the crab can be a beneficial addition to a balanced diet. However, those with allergies, gout, high cholesterol concerns, or sensitivity to mercury should exercise caution or avoid crab consumption altogether. As with any food, moderation and consideration of individual health factors are key to enjoying the full benefits of this remarkable crustacean.
