Crabs Diet And Fresh Crabs NutritionSince crabs have ten legs, they are called decapods.
Crabs grow in size by a process of molting - they shed their hard shell, and swell up in size by ingesting lots of water. For a few days, they are covered only by a soft shell, which gradually hardens, until the next molting.
Some gourmets prefer these soft-shelled crabs, claiming they are more succulent and sweet.
Whatever the preference, crab-meat is universally considered a delicacy
But there is a widespread notion, that crabs are not good for your health. Nutritionists however argue that crab meat is nutritionally good as it is high in vitamins and high quality proteins and amino acids.
It is also rich in minerals such as calcium, copper, zinc, phosphorus and iron, while having lower levels of fat and carbohydrates.
Crabs Nutrition And Health Benefits Of CrabsGood for diabetics: Along with all other shellfish, crabs are rich in chromium, which helps insulin to metabolize sugar, and thereby lowers the blood glucose levels in the body.
Anti-cancer properties: All shellfish and crab too, have plentiful amounts of selenium. Selenium is an anti-oxidant, and cancels out the carcinogenic effects of cadmium, mercury and arsenic, which can cause tumors. Higher levels of selenium in the blood lead to lower rates of cancer. In fact, lysate, which is extracted from the blue blood of the horse-shoe crab is used for detection of spinal meningitis and for fighting cancer.
Heavy Cholesterol? While blue crabs have 28mg of cholesterol per ounce, Dungeness crabs have only 22mg and Alaska king crabs have as little as15mg. Compare this with chicken - 22mg and a sirloin steak - 25mg.
While crab meat crab meat is low in saturated fat, the presence of chromium helps to increase the level of HDL (good cholesterol) in the body, and thus reduces the risk of strokes and coronary and circulatory heart disease.
In fact, crabs contain sterol, which restrict the absorption of other cholesterol, eaten during a meal.
Omega-3 fatty acids: Crabs, like all shellfish, are also rich in omega-3 fatty acids, which it gets from phytoplanktons and algae.
Omega-3 fatty acids, help in reducing the stickiness of blood platelets, thus making red blood cells more flexible and ensuring smoother flow. Omega-3 helps to reduce the level of tri-glycerides and LDL (low-density lipo-proteins), which choke up artery walls as deposits.
However, one must stick to moderate quantities, and in case you are on a very restricted diet, first consult your dietician or doctor.
