Crustaceans are edible fish that are either shelled mollusks or crustaceans. It is eaten in different ways in different dishes, depending on taste and cooking method. All crustaceans are generally low in calories, are a good source of protein and healthy fats, and also contain various nutrients such as zinc, B12, iron and selenium. Steaming or roasting them is more nutritious than cooking them. Crustaceans are common in the UK. They can be purchased fresh or frozen from most supermarkets, local fishmongers, and online delivery companies. The sustainability of various shellfish depends on the variety and country in which they are caught. For example, small shrimp such as cold-water and northern shrimp are more sustainable than large jumbo or tiger shrimp, but farmed or hand-harvested clams are best, as wild clam harvesting is confusing. Always look for sustainability certifications when buying shellfish, and check out the Marine Conservation Society's Good Fish Guide for the most relevant information on various shellfish and their latest sustainability ratings.

Crustaceans, especially crustaceans, are rich in amino acids, known as the "building blocks" of proteins, as they are required not only for the synthesis of hormones and neurotransmitters, but also for growth and repair. Contains polyunsaturated fats (PUFAs) and good amounts of omega-3 fatty acids. These PUFAs help lower LDL (bad) cholesterol and reduce the risk of heart disease. Certain shellfish are rich in carotenoids, such as beta-carotene, which are converted to vitamin A when eaten. Carotenoids are powerful antioxidants, especially vitamin A, which is necessary for healthy immunity. Astaxanthin is a red-orange carotenoid typically found in “pink” shellfish such as crayfish, shrimp and lobster. This antioxidant protects the skin from aging and helps maintain moisture and elasticity. Most shellfish are rich in vitamin B12, an important nutrient required for healthy bone formation. Low vitamin B12 levels, also known as pernicious anemia, can increase the risk of osteoporosis with age. Due to the way they live and feed, crustaceans come into contact with a wide variety of organisms that can be harmful to humans if ingested. That's why it's so important to carefully wash and prepare all crustaceans and heat them well before consuming them. With a gentle tap, the shell closes and closes.
