Crab meat is a popular and versatile type of seafood. Crabs are one of the oldest species that can be seen throughout the world. These living beings undergo a process of molting i.e. where they shed their outer skin and swell up in size by ingesting lots of water; then they are covered by a softer shell, which hardens until the next molting stage.King crabs, also known as stone crabs, are a family of crustaceans found mainly in cold seas.
Since crabs have ten legs, they are called decapods.They are very large in size, in short supply, and have a tasty flesh that makes them a delicacy. King crab legs are an especially popular delicacy that offers many nutritional benefits.It is also very healthy and a good addition to a balanced diet, as it contains many nutrients coupled with a low fat content.
Rich in vitamins and minerals, crab meat is also low in fat and contains Omega-3 polyunsaturated acids.These help provide protection from heart disease and aid brain development. Some research suggests that Omega-3 also inhibits aggressive behavior. And it’s not just any old Omega-3 – it’s the long chain variety. These are more beneficial to our health because they can be used immediately, unlike short-chain Omega-3 found in vegetables and oils.
King crab leg (134g) cooked and served plain, provides 130 calories, 2.1g of fat, .2g of saturated fat, and zero trans fat, carbohydrate, sugar and dietary fiber. One leg of the aforementioned serving size provides about 26g of protein, making it an excellent source of protein, though it is much leaner than the same amount of beef. Although king crab is a source of cholesterol, containing about 71mg per serving, it need not be avoided for this reason as saturated and trans fats (which are not in crab legs) have a far more negative impact on blood cholesterol levels.
Riboflavin (Vitamin B2) is important in the production of steroids and red blood cells, the promotion of normal growth, and the maintenance of the skin, eyes and the nervous system.Riboflavin also plays a role in iron absorption in the digestive tract and supports the activity of antioxidants.
Crab is also a good source of vitamins A, C and the B vitamins including B12, and minerals like zinc and copper. It is a source of selenium, which may be a means of preventing cancer. Crab also has some chromium, which is considered a useful mineral if you have insulin resistance, as it may improve blood sugar metabolism.100g of crab meat provides 112% of the daily recommend value for men and 140% daily recommend value for women. Crab meat contains 3 times the amount of Selenium than cod and 12 times that of beef.
Phosphorus is after calcium the second most abundant mineral in the body. It is a principal mineral of bones and teeth and is therefore important in skeletal health and development.Phosphorus is involved in most metabolic actions in the body, including kidney functioning, cell growth and the contraction of the heart muscle. It is also involved in converting food to energy.100g of crab provides 62% of daily recommended value for adult men and women.
Crab makes excellent seafood for health conscious individuals, who control their calorie intake. Four ounces of crab meat gives only 98 calories and 2 grams of fat.Apart from being low in calories, crabs provide sufficient amounts of protein. For athletes and bodybuilders, they are good choice of protein.The potassium content in crab promotes the growth of healthy cells while sodium helps in regulating blood pressure.
Crabs are also a good source of selenium, which aids in reducing oxidative damage to cells and tissues. This mineral, found in crabs, acts as an antioxidant by cancelling out the carcinogenic effects of cadmium, mercury and arsenic, known to cause tumours. Higher the levels of selenium, lower are the risks of cancer.
Note: Crab may also easily cause food poisoning if it is not treated and prepared correctly. Crab must be fresh, without a strong odor and should be kept cold or frozen if it is not eaten immediately.
