The reasons that we do not eat or recommend shellfish are very similar. Shellfish are bottom feeders and feed on parasites and dead skin, many times from dead animals. They do not have appropriate digestive and filter systems to purify toxins and parasites from their body and flesh.
There are two types of shellfish: crustaceans (crab, lobster, and shrimp) and mollusks (clams, mussels, and oysters). Crustacean shellfish are considered the. most allergenic. Because many people with allergies. to one type of shellfish are also allergic to other types, it may be advised to avoid all shellfish.
