Calories and Nutritions in Halibut

A 100g (3.5 oz) serving of raw halibut (generic) contains 91 calories. A 100g (3.5 oz) serving of cooked halibut (dry heat, e.g., baked or broiled) provides 111 calories.

One kilogram (1000g, 35.27 oz) of raw halibut (generic) contains 910 calories. One kilogram (1000g, 35.27 oz) of cooked halibut (dry heat) provides 1110 calories.

The calorie content of one halibut fillet varies significantly based on its weight. A small 4 oz (113g) raw halibut fillet contains 103 calories. A common restaurant-sized 6 oz (170g) raw halibut fillet provides 155 calories. A larger 8 oz (227g) raw halibut fillet has 207 calories. Cooked, a 6 oz (170g) halibut fillet (dry heat) would contain 189 calories.

Halibut provides some health benefits like supporting heart health and providing essential nutrients due to its rich composition of lean protein, omega-3 fatty acids, vitamins, and minerals. A list of the health benefits of halibut are shown below:

• Excellent Source of High-Quality Protein: Halibut is packed with lean protein, which is essential for building and repairing tissues, producing enzymes and hormones, and maintaining muscle mass. (Paddon-Jones, D. & Rasmussen, B.B., 2009, "Dietary protein recommendations and the prevention of sarcopenia").
• Rich in Omega-3 Fatty Acids: Halibut contains beneficial omega-3 fatty acids, primarily EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These fatty acids are known to support heart health by reducing triglycerides, lowering blood pressure, and reducing the risk of blood clots and irregular heartbeats. (Mozaffarian, D. & Rimm, E.B., 2006, "Fish intake, contaminants, and human health: evaluating the risks and the benefits").
• High in Selenium: Halibut is an excellent source of selenium, a trace mineral that acts as a powerful antioxidant. Selenium helps protect cells from damage, supports thyroid function, and plays a role in immune system health. (Rayman, M.P., 2012, "Selenium and human health").
• Good Source of B Vitamins: It provides several B vitamins, including niacin (B3), vitamin B6, and vitamin B12. These vitamins are crucial for energy metabolism, nervous system function, red blood cell formation, and DNA synthesis.
• Provides Phosphorus and Magnesium: Halibut is a good source of phosphorus, which is vital for bone health, energy production, and cell membrane structure. It also contains magnesium, important for muscle and nerve function, blood sugar control, and blood pressure regulation.
• May Support Brain Health: The omega-3 fatty acids, particularly DHA, found in halibut are important for brain development and function throughout life. They may help reduce the risk of cognitive decline. (Swanson, D., et al., 2012, "Omega-3 Fatty Acids EPA and DHA: Health Benefits Throughout Life").
• Can Contribute to Reduced Inflammation: The omega-3 fatty acids in halibut possess anti-inflammatory properties, which may help alleviate symptoms associated with inflammatory conditions. (Calder, P.C., 2006, "n-3 polyunsaturated fatty acids, inflammation, and inflammatory diseases").

Halibut has been known to cause some unwanted effects like potential mercury exposure and sustainability concerns due to its characteristics as a large, predatory fish. A list of the downsides of halibut are shown below:

• Potential for Mercury Contamination: As a large, long-lived predatory fish, halibut can accumulate mercury from its diet. Mercury is a neurotoxin, and high levels of exposure can be harmful, especially to pregnant women, nursing mothers, and young children. Regulatory agencies like the U.S. FDA and EPA provide guidelines on fish consumption to minimize mercury risk. (U.S. Food and Drug Administration, "Advice About Eating Fish").
• Sustainability Concerns for Some Populations: Certain populations of halibut, particularly Atlantic halibut, have faced overfishing in the past, leading to concerns about their sustainability. Pacific halibut populations are generally better managed, but it is important to choose halibut from sustainable sources. (Monterey Bay Aquarium Seafood Watch, "Halibut").
• Purine Content: Halibut contains purines, which are broken down into uric acid in the body. Individuals with gout or a predisposition to high uric acid levels may need to moderate their intake of purine-containing foods, although halibut is not as high in purines as some other seafood or red meats.
• Cost: Halibut can be more expensive than other types of white fish due to its desirability, fishing regulations, and sometimes limited supply.

Yes, halibut is good for you when sourced responsibly and consumed in moderation as part of a balanced diet. It is a nutrient-dense fish, offering high-quality lean protein, beneficial omega-3 fatty acids (EPA and DHA), and a wealth of essential vitamins and minerals, including selenium, niacin, vitamin B12, vitamin B6, phosphorus, and magnesium. These nutrients contribute significantly to heart health, brain function, immune support, and overall cellular health (Grieger, J.A. & Skilton, M.R., 2020, "The role of fish and seafood in the prevention of all-cause mortality, cardiovascular disease, and type 2 diabetes: A systematic review and meta-analysis of prospective cohort studies"). While concerns about mercury exist, particularly for Atlantic halibut, choosing Pacific halibut and adhering to consumption advisories from health authorities can mitigate this risk (Mahaffey, K.R., et al., 2009, "Balancing the benefits of n-3 polyunsaturated fatty acids and the risks of methylmercury exposure from fish consumption"). For most adults, the nutritional benefits of consuming halibut outweigh the potential risks when eaten as recommended.

The calorie content of halibut varies somewhat between its different types, primarily due to differences in their natural fat content. Pacific halibut and Atlantic halibut are quite similar in their caloric values when cooked using dry heat methods like baking or broiling, both containing around 110 to 115 calories per 100g. California halibut also falls into this low-calorie range with about 110 calories per 100g cooked. These types are considered lean white fish. Greenland halibut, often marketed as Turbot, is a distinct species and generally has a higher fat content than Pacific or Atlantic halibut. Consequently, cooked Greenland halibut is more calorie-dense, ranging from 140 to 195 calories per 100g, depending on the specific cut and preparation. The primary driver for calorie differences among true halibut species (Pacific and Atlantic) is minimal, with preparation methods (frying vs. baking) having a much larger impact on the final calorie count of a dish than the slight variations between these lean types.

No, halibut, particularly Pacific and Atlantic halibut, is generally considered a lean fish, not a fatty fish. The halibut fat content for these species is low. A 100g serving of cooked Pacific or Atlantic halibut contains only 1.6g to 2.5g of total fat.

A significant portion of the fat in halibut consists of healthy unsaturated fats, including beneficial omega-3 fatty acids (EPA and DHA). It is not categorized alongside fatty fish like salmon, mackerel, herring, or sardines, which have much higher total fat contents (often 10-20g or more per 100g). Greenland halibut (often called Turbot) is an exception and has a higher fat content compared to Pacific and Atlantic halibut, making it moderately fatty.

The use of halibut in desserts is virtually nonexistent and would be considered highly unconventional in any culinary tradition. Halibut is a savory fish with a distinct oceanic flavor and firm texture, which does not lend itself to sweet dessert applications.

Halibut are large flatfish belonging to the flounder family, with their origin as a significant food source tracing back to coastal communities in the North Atlantic and North Pacific oceans where these fish are native. The name "halibut" itself is believed to derive from Middle English "haly" (holy) and "butte" (flatfish), possibly because it was a popular fish to eat on holy days. For centuries, indigenous peoples of the Pacific Northwest and North Atlantic regions, as well as early European settlers and fishermen in these areas, relied on halibut as a vital source of protein and sustenance. Its impressive size (Atlantic halibut can grow to be hundreds of pounds) made it a valuable catch.
