Calamari offers several health benefits due to its rich concentration of protein, minerals, and omega-3 fatty acids, especially if prepared without excessive fat or sodium. The most important health benefits are detailed below.

• Excellent Source of Lean Protein Calamari provides a high amount of complete protein, which is essential for building and repairing tissues, creating enzymes and hormones, and maintaining muscle mass. Protein-rich foods also promote a feeling of fullness, which can aid in weight management. A review on the role of protein in the diet confirms its importance for satiety and body composition. (Paddon-Jones, D., et al., 2008, Protein, weight management, and satiety).
• Rich in Essential Minerals Calamari is a source of important minerals, including selenium, copper, and phosphorus. Selenium is a powerful antioxidant that helps protect cells from damage, copper is crucial for forming red blood cells and maintaining nerve cells, and phosphorus is vital for bone health and energy metabolism. The importance of these micronutrients for overall health is well-established in nutritional science. (Shenkin, A., 2006, The key role of micronutrients).
• Provides Omega-3 Fatty Acids Calamari contains the omega-3 fatty acids EPA and DHA, which are known for their anti-inflammatory properties and benefits for cardiovascular and brain health. Regular consumption of seafood rich in these fatty acids is linked to better health outcomes. A major review of studies concluded that fish and omega-3 fatty acid consumption reduces the risk of coronary heart disease mortality. (Mozaffarian, D., & Rimm, E. B., 2006, Fish intake, contaminants, and human health: evaluating the risks and the benefits).

The downsides of calamari are related to its high cholesterol content and the unhealthy way the substance is commonly prepared. An alternative for a lean seafood choice is grilled shrimp or cod. The American Heart Association recommends eating two servings of fish (particularly fatty fish) per week, and calamari can be one of these servings if prepared healthily. The table below shows the potential downsides of calamari.

• High in Dietary Cholesterol Calamari is naturally high in dietary cholesterol. While the impact of dietary cholesterol on blood cholesterol levels varies among individuals, people with certain health conditions may be advised to limit their intake. Research on this topic continues, but guidelines have historically recommended caution for those at risk for heart disease. (Grundy, S. M., et al., 2019, 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA Guideline on the Management of Blood Cholesterol).
• Unhealthy Preparation Methods The most popular way to eat calamari is deep-fried, which adds a significant amount of calories, unhealthy fats, and sodium from the batter and cooking oil. Consuming fried foods regularly is associated with an increased risk of obesity, heart disease, and other chronic conditions. A large prospective study linked frequent fried-food consumption to a higher risk of major cardiovascular events. (Gadiraju, T. V., et al., 2015, Fried food consumption and cardiovascular health: a review of the current evidence).
• Potential for Allergic Reactions As a mollusk, squid is a potential allergen. Allergic reactions to shellfish can be severe and may include hives, swelling, and difficulty breathing. Individuals with a known shellfish allergy must avoid calamari completely. (Kamath, S. D., et al., 2014, Characterisation of the major allergens in the gastropod Haliotis asinina (tropical abalone)).

Yes, calamari can be good for a person's health when prepared in a healthy way, such as grilling or baking, because the substance is a nutrient-dense food. For brain health, the omega-3 fatty acids, particularly DHA, found in squid are essential components of brain cell membranes, and research shows a strong link between seafood consumption and improved cognitive outcomes (Gómez-Pinilla, F., 2008, Brain foods: the effects of nutrients on brain function). For heart health, these same omega-3s can help lower triglyceride levels, though this benefit can be offset if the calamari is fried in unhealthy oils, which adds saturated and trans fats (Mozaffarian, D., & Rimm, E. B., 2006, Fish intake, contaminants, and human health: evaluating the risks and the benefits). From a metabolic standpoint, calamari provides high-quality, lean protein and B vitamins, which support muscle maintenance and energy production, as demonstrated by studies on the role of protein in satiety and lean mass preservation (Paddon-Jones, D., et al., 2008, Protein, weight management, and satiety).

The calorie content of calamari changes based on the cooking method. The lowest calorie form is raw squid, which contains 92 calories per 100 grams. Grilling and baking add a moderate number of calories. Grilled calamari has 158 calories per 100 grams, and baked calamari has 165 calories per 100 grams; this increase is due to the addition of oils, marinades, or light breading. The highest calorie preparation is fried calamari, which contains 175 calories per 100 grams. The significant calorie jump in fried calamari comes from the batter, which adds carbohydrates, and the absorption of a substantial amount of oil during the deep-frying process.

Classic sauces for fried calamari include marinara sauce, garlic aioli, and tartar sauce. Marinara sauce provides a bright, acidic contrast to the richness of the fried coating. Garlic aioli offers a creamy, pungent counterpoint that enhances the savory flavor of the seafood. Tartar sauce gives a tangy and creamy element with the added texture of pickles and capers. A simple squeeze of a fresh lemon wedge is also a classic accompaniment, with the acidity cutting through the fat and brightening the calamari's delicate taste. 

Neutral oils with a high smoke point are best for frying calamari. Oils like canola, peanut, vegetable, and safflower oil are ideal choices. These oils are preferred because a high smoke point, well above the optimal frying temperature of 350-375°F (175-190°C), prevents the oil from burning. When oil burns, the substance develops a bitter, unpleasant taste and releases harmful compounds. A neutral flavor is also crucial because the substance does not interfere with the delicate, sweet taste of the calamari. Using these oils helps the calamari achieve a crispy, golden-brown exterior without affecting its delicate taste.

The origin of calamari as a food source is ancient, deeply rooted in the coastal communities of the Mediterranean Sea and East Asia. For thousands of years, civilizations in Greece, Italy, Spain, China, and Japan have harvested and consumed squid as a readily available source of protein. The term "calamari" itself is the Italian word for squid, derived from the Latin calamarium, meaning "ink pot," a reference to the squid's ink sac. The popularization of the specific dish known as fried calamari in North America is a much more recent phenomenon. This appetizer, consisting of battered and deep-fried squid rings, was introduced to the American dining scene by Italian-American restaurants. The dish began to gain widespread popularity in the 1970s and 1980s, becoming a ubiquitous offering on restaurant menus across the country. The adoption of the Italian name "calamari" by restaurants helped to position the dish as a more sophisticated offering than simply "fried squid."
