Crab calories and nutrition facts
100 grams of crab contains 97 calories, with 19.4 g of protein, 0 g of carbohydrate and 1.5 g of fat. Most of its calories come from protein.
Crab meat is almost pure protein at about 82 calories per cooked 3 oz, one of the leanest things in the seafood counter. The calories in a crab dish come from what joins it — butter, mayonnaise, the bread underneath. Picked white meat is a fair shortcut, though the brown meat carries most of the flavour.
