Health benefits of eating crab meat
Good 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.
All shellfish, including crab, have generous amounts of selenium. Selenium is an anti-oxidant and cancels out the carcinogenic effects of cadmium, mercury and arsenic, which can cause tumors in humans. It has been proved that 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.
