With the above nutrition values, let’s understand the potential health benefits of including squid in your diet.
Potential Health Benefits Of Squid
Most health benefits of squid have been primarily linked to its high content of protein, trace minerals, and omega-3 fatty acids. Let’s understand this further below.
Rich In Heart-friendly Omega-3 Fatty Acids
Squid contains a decent amount of beneficial omega-3 fatty acids (1). Omega-3 fatty acids, with their anti-inflammatory properties, play many important roles in the human body, especially in reducing the risks of cardiovascular and other chronic diseases (2),(3).
Good Source Of Muscle-building Protein
Squid provides 15.6 grams of protein per 100 g serving. Also, squid is a complete protein which means that it contains adequate amounts of all nine essential amino acids required for building the tissues and muscles of our body (1).
Low In Poisonous Mercury
Squid is one of the safest seafood options when it comes to mercury contamination. The average mercury content in squid meat based on 36 commercially available samples was found to be 0.024 ppm (parts per million) (4). Among the popular seafood choices, squid fares better than tuna, sardine, crabs, and lobster.
Contains Brain-healthy Choline
With 65 mg of choline per 100-gram serving, squid is a good source of choline after eggs (1). Choline is an essential trace nutrient that is crucial for brain and liver health (5). It also helps prevent spinal abnormalities in developing fetuses. According to the National Health and Nutrition Examination Survey, only 10.8% of Americans meet the adequate intake (AI) recommendations for choline (6). Including squid in your diet can help get more of this vital nutrient.
Rich In Antioxidant Selenium
Squid contains about 44.8 µg of selenium per 100 g of its serving, which is equivalent to 64% of the RDA (recommended daily intake) (1). Selenium is a vital trace mineral that has important antioxidant properties. In the human body, selenium activates various selenoproteins that help improve your immunity and may protect you from multiple health issues related to heart health and cancer (7), (8), (9).
Potential Risks Of Squid
Squid is generally considered a safe food option when consumed in moderation. The only things you need to be mindful about are their high cholesterol content and any possible allergic reactions.
Shellfish Allergy
As with any sort of shellfish, squid poses the risk of an allergic reaction just like its mollusk cousins— oysters, mussels, and clams (10). One of the major allergens found in squid is thought to be a squid muscle protein called tropomyosin (11). While allergy to the crustacean species like crab, lobster, or shrimp is more common than mollusk allergies, there is a possibility of cross-reactive allergic reactions. That means you might be allergic to squid if you are already allergic to any crustaceans (10), (12). Symptoms might include mild rashes, itching, hives, swelling, or breathlessness (10). Allergic reactions might become severe very quickly and you should speak to your doctor if you suspect any uneasy reactions to the consumption of squid.
High In Cholesterol
With 233 mg of cholesterol per 100 g, squid is a good source of dietary cholesterol (1). The cholesterol content can further increase based on the cooking and preparation of the dish. For instance, having fried squid rings though tasty would not be a suitable option for people with cardiovascular concerns. Baking, broiling, or over-roasting can help you enjoy squid in a healthier way. Now, fried squid rings are often called “calamari” in certain regions of the world. While that may make it sound more exclusive and expensive, “calamari” is actually another kind of cephalopod. Let’s understand the basic differences between squid and calamari in the next section.
Squid Vs. Calamari
Squid and calamari are often confused and used interchangeably in many parts of the world. However, these are 2 different species of cephalopods that are quite similar to each other with a few minor differences. While identifying squid from calamari may need a trained eye, differentiating squid from shrimp might seem easier due to their obvious physical appearances.
Squid Vs. Shrimp
When you want to cook seafood, there are a few popular options available including squid and shrimp. Having a knowledge of how to identify them and their nutritional differences would help you decide which goes best for the dish and your liking. The first thing you can notice when you look at both squid and shrimp is the difference in their bodies and physical appearance. While squid being a mollusk doesn’t have any outer covering or shell, shrimp being a crustacean has its characteristic outer shell covering. While squid is mildly sweet and tender to taste, shrimp tastes similar to chicken with a slight bite to it. Both can get chewy easily if overcooked. Apart from the above, let’s understand how they fare against each other when it comes to their nutritional differences. As is evident from the nutritional facts above,
Squid has slightly more calories than shrimp Squid is considerably higher in cholesterol than shrimp Shrimp has more than twice the amount of sodium and phosphorus. While squid has more carbohydrates and iron, shrimp has more protein and iron per 100 g.
Having understood these differences, if you choose to go ahead with squid as your choice of seafood, let us understand how to prepare and cook them in different ways.
Cooking With Squid
You can get fresh squid from your fishmonger or at the seafood counter of most major supermarkets. Fresh squid looks smooth and shiny with a mild, fresh smell of the sea. If it smells fishy or looks wrinkled and dull, you should avoid buying it. Also, if you don’t find fresh squid, you can look for frozen or dried squid as well. When it comes to taste and texture, squid is mildly sweet and tender and can easily absorb the flavors of other ingredients, herbs, and spices in your dish. Though squid tends well to different cooking methods like grilling, sauteing, frying, or even slow-cooking, it is very time-sensitive and can turn chewy and rubbery on overcooking. Although the squid tentacles are also edible, it is the body that is the prime portion of meat. While it can be stuffed and cooked as a whole, it is usually cut into crossed slices, flat pieces, or simple rings and fried to make the most of its bite and flavor. Here is how you can prepare the squid rings for further cooking:
Put the squid rings or pieces into a large bowl of cold water. Move and gently wash each ring with your hands. Be careful to remove any pieces of connective tissue or membrane from the rings. Drain the cleaned squids with a strainer. Boil enough water in a large saucepan or stockpot. Add in the squid rings and allow them to cook for 2 minutes. Drain out the cooked rings and transfer them to a clean bowl. You can then use the squid rings immediately or let them cool down for later use.
To Sum Up
Squid is a versatile seafood option that is mild and tender to taste. It is a good source of protein, trace minerals, vitamins, and heart-healthy omega-3 fatty acids that altogether define most of the key squid benefits. While it can be prepared and cooked in several ways, fried squid rings are most popular worldwide. Though tasty and versatile, fried squid rings are high in cholesterol and fats. Apart from cholesterol, seafood allergy is the only other concern. Other than that, you can enjoy squids in your diet anytime. Is squid good for high blood pressure?
