Oysters were previously reviewed in this article, but you should keep in mind that all other shellfish products are also extremely healthy for you. Since they are a meat-based product, that means you are going to be getting a lot of protein from them. And just like oysters, shellfish are going to be rich with zinc and other trace minerals. For example, a 3-ounce serving of an Alaskan King Crab has a whopping 43-percent of your total daily zinc requirement.
