Crab, white meat, purchased cooked

White crab meat is the white flesh of crab, a type of shellfish. The figures here refer to meat purchased already cooked. It mainly provides protein, with 21g per 100g, alongside 0.3g of fat and 0.81g of salt. It also provides minerals, including iodine at 103µg per 100g.

Protein helps the body maintain and repair tissues. Iodine is needed to make thyroid hormones, which help regulate metabolism. Although this cooked crab meat contains little fat, its salt content is worth noting for people monitoring their salt intake.
