Crab
What it is
Crab is a crustacean eaten as seafood. This reference describes blue crab cooked with moist heat.
What it does
For the named reference food, USDA lists 83 kcal, 17.9 g protein and 0.74 g total fat per 100 g edible portion. The table gives additional nutrients for that same food form. These figures describe composition, not an effect on a disease or a recommended serving.
Research context and ingredient forms
Reference food: Crustaceans, crab, blue, cooked, moist heat. These are historical SR Legacy data from the April 2018 release, published in FoodData Central in 2019. A different variety, preparation, water content, or commercial recipe can change the result. For a matching food, a portion estimate scales each value by edible portion grams divided by 100.
Using this information
The table covers edible crab meat, not shell weight. Imitation crab is a different formulated food, and crab cakes also include their other ingredients.
Considerations
Crustacean shellfish is a major food-allergen category. The nutrient profile does not establish suitability for someone with a shellfish allergy.
