King crabs, which are also called stone crabs, belong to a crustacean family that mostly resides in cold seas. They are literally big crabs (hence the name) that are unfortunately low in supply today, but because of their tasty flesh, they have become a popular delicacy. King crab legs are a particular favorite, not only for their flavor but also for the number of health benefits they offer.

An Alaskan king crab leg, for example, has around 26g of protein and is thus an excellent source of the macronutrient, not to mention it is leaner than beef in the same amount. And while king crab has around 71 mg of cholesterol per serving, barely any of it comes from saturated fats and trans fats, the two most dangerous sources of the lipid.

Omega-3 in Fat
A king crab leg contains about .7 polyunsaturated fat and .2 gram of monounsaturated fat, both of which are healthy for the heart. King crab is especially rich in a certain group of essential polyunsaturated fatty acids widely known for its health benefits: omega-3 fatty acids. A single serving offers around 614 mg of omega-3, which makes it one of the best food sources of these fatty acids. No less than the American Heart Association has cited the anti-inflammatory properties of this nutrient, as well as its ability to keep low-density lipoprotein (LDL) or “bad” cholesterol from sticking to arterial walls.
Vitamins
As with all other types of seafood, king crab legs are high in vitamin C – around 10.2g per serving, or some 13.5 percent of the Recommended Dietary Allowance (RDA). It also has at least 68 mg of folate (17%percent of the RDA) and an impressive 15.4 mcg of vitamin B12 (above 200 percent of the RDA).
Minerals
King crab legs are also a fantastic source of minerals, such as magnesium (20% of the RDA), copper (75% of the RDA), phosphorus (50% of the RDA), selenium (almost 100% of the RDA) and zinc (almost 100% of the RDA). These minerals are involved in several functions of the body, such as immunity, bone health, and RBC and protein formation. King crab legs are, however, high in sodium, being salt-water species. A single leg can contain over 1,400mg of this mineral, but still, this should not be a problem. When eating crab legs, make sure to chase them down with a lot of water to dilute the sodium.
