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. Crabs 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. While crab meat is considered low in saturated fat, the presence of chromium helps increase the level of HDL (good cholesterol) in your body, and thus reduces the risk of strokes, coronary and circulatory heart disease. They are also a rich source of omega 3 fatty acids.
Rich in vitamins and minerals, crab meat is also low in fat and contains Omega-3 polyunsaturated acids. Helps provide protection from heart disease and aids brain development.
Although crab meat and shrimp do contain cholesterol, they might not have an overly large effect on your cholesterol levels if you eat them in moderation. When it comes to raising your cholesterol levels, saturated fat content is much more important than dietary cholesterol.
