Dungeness crab earns a strong FoodScore of 81/100, placing it in the 'Very Good' category. This high score is largely driven by its excellent protein content, providing 22.32g per 100g serving, which contributes a significant +10 bonus. The crab also receives a substantial +12 bonus for its rich micronutrient profile, particularly its high levels of magnesium, phosphorus, zinc (50% DV), vitamin B12 (433% DV), folate, and riboflavin. Furthermore, as a minimally processed whole food (NOVA class 1), it gains another +10 bonus, reflecting its natural state and lack of unhealthy additives. The primary deduction comes from its sodium content, with 378mg per 100g resulting in a -1 penalty. To achieve an even higher score, the sodium content would need to be lower, which can often be managed through preparation methods rather than inherent changes to the food itself. Overall, its strong macro and micronutrient contributions significantly outweigh this minor penalty.
Health benefits
What the nutrients in crab dungeness cooked actually do for you, grounded in established dietary science.
Supports Muscle Health and Repair
Dungeness crab is an excellent source of high-quality protein, essential for muscle growth, repair, and overall tissue maintenance. A 100g serving delivers 22.32g of protein, which is a substantial portion of the daily recommended intake for adults. This protein provides all essential amino acids, making it a complete protein source. Adequate protein intake is crucial for individuals engaged in physical activity or those looking to maintain muscle mass as they age, supporting satiety and metabolic health.
Boosts Brain Function and Nerve Health
This seafood is exceptionally rich in Vitamin B12, providing an impressive 433% of the Daily Value per 100g. Vitamin B12 is vital for neurological function, red blood cell formation, and DNA synthesis. It plays a key role in maintaining the health of nerve cells and supporting the production of neurotransmitters, which are crucial for mood regulation and cognitive processes. Including Dungeness crab in your diet can significantly contribute to optimal brain health and energy levels.
Enhances Immune System Function
Dungeness crab is a significant source of zinc, supplying 50% of the Daily Value in a 100g serving. Zinc is a critical trace mineral involved in numerous bodily functions, including immune system support, wound healing, and cell division. It helps the body fight off infections and plays a role in the proper functioning of many enzymes. Regular consumption of foods rich in zinc, like Dungeness crab, can help maintain a robust immune response.
Contributes to Heart Health
Dungeness crab contains omega-3 fatty acids, with 0.39g per 100g, which are recognized for their benefits to cardiovascular health. Omega-3s, particularly EPA and DHA, help reduce inflammation, lower triglyceride levels, and support healthy blood pressure. Additionally, its low saturated fat content (0.17g per 100g) aligns with dietary recommendations for a heart-healthy diet. While not as high in omega-3s as some fatty fish, it still contributes positively to overall intake.
Supports Bone and Nerve Health
Dungeness crab provides meaningful amounts of magnesium and phosphorus, both essential minerals for bone health and nerve function. A 100g serving offers 14% of the Daily Value for magnesium and contributes to phosphorus intake. Magnesium is involved in over 300 enzymatic reactions, including those that regulate muscle and nerve function, blood glucose levels, and blood pressure. Phosphorus is a major component of bones and teeth, and plays a crucial role in how the body uses carbohydrates and fats. These minerals work synergistically to support skeletal integrity and cellular processes.
Dungeness crab is a highly nutritious seafood, scoring 81/100, primarily due to its rich protein content and impressive micronutrient profile.
