Many sea animals are high in nutrients, but shellfish may be among the most nutritious of all. Commonly consumed types of shellfish include clams, oysters, scallops and mussels. Clams are among the best sources of vitamin B12 in existence, with 100 grams of clams supplying over 16 times the RDI. They are also loaded with vitamin C, various B vitamins, potassium, selenium and iron (25). Oysters are also very nutritious. Only 100 grams supply 600% of the RDI for zinc, 200% of the RDI for copper and large amounts of vitamin B12, vitamin D and several other nutrients (26).
Though shellfish are among the world’s most nutritious foods, most people rarely consume them.
