If you are buying them fresh, buy them unpeeled, and if frozen, then uncooked, meaning they are grey and turn pink after cooking. They are considered lower-quality seafood, just as pork is considered lower-quality meat. When cooking, it is advisable to use garlic, white wine, etc. When purchasing, be careful to ensure the shrimp have not been chemically treated and do not contain added water.

Shrimp contain iodine, zinc, magnesium, calcium, and a large amount of protein.

They have a salty and sweet taste and a warm nature. They strengthen the kidneys. They are not suitable for allergy sufferers, just like other seafood.
