Shrimp, like their crawling cousins, crabs and lobsters, have attained a favored status in many cuisines of the world. It is little wonder. Their delicate, mild flavored flesh offers protein that is low in calories and saturated fat and they are a good source of omega-3 fatty acids, reports CholesterolCholesterol.
