As a lean source of high-quality protein, it offers a range of health benefits with a low-fat content. This makes it an attractive option for those looking to add more seafood to their diet. The precise amount of protein can vary slightly depending on the crab species, but all varieties provide a substantial and valuable contribution to your daily nutritional intake.
