Carbs
Plain raw mackerel does not contain any carbohydrates, fiber, or sugar. However, it's important to note that breaded or processed mackerel may contain some carbohydrates.
Fats
Mackerel is a rich source of healthy fats, providing almost 14 grams of fat per 100-gram serving. Of this, 3 grams are saturated fat, 5 grams are monounsaturated fat, and 4 grams are polyunsaturated fat.
Mackerel is particularly high in omega-3 fatty acids, including EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are essential for optimal health. These fatty acids cannot be produced by the body in sufficient amounts, so it's important to consume them through food sources like mackerel.
In addition to EPA and DHA, mackerel also contains a lesser-known omega-3 fatty acid called DPA (docosapentaenoic acid), with a 100-gram serving providing 0.18 grams of this beneficial fatty acid.
Protein
Mackerel is a complete protein, meaning it contains all nine essential amino acids that the body needs. A 100-gram serving of mackerel provides 19 grams of protein, making it an excellent choice for those looking to increase their protein intake.
Vitamins and Minerals
Mackerel is packed with essential vitamins and minerals. It is an excellent source of vitamin B-12, providing 71µg per serving. Mackerel also contains niacin, iron, vitamin B6, riboflavin, magnesium, phosphorus, folate, and selenium.
Additionally, mackerel may be a good source of vitamin D, with a 100-gram serving containing 643 IU. However, it's important to note that the actual vitamin D content in fish can vary and may be lower than anticipated.
Health Benefits
Eating mackerel can have several health benefits, including:
Improved Heart Health
Mackerel is rich in omega-3 fatty acids, which have been shown to reduce the risk of cardiovascular disease. These fatty acids can help lower triglyceride levels and have a positive impact on overall heart health.
Consuming seafood, including mackerel, has been linked to improved cognitive function, particularly in individuals with mild Alzheimer's disease. Regular consumption of mackerel may help prevent age-related cognitive decline.
Improved Cardiometabolic Health in Children
Studies have shown that consuming fatty fish, like mackerel, can have positive effects on the development and health of children. Introducing mackerel into children's diets may improve triglyceride levels and HDL cholesterol levels without negatively impacting blood pressure or glucose levels.
Prevention of Anemia
Mackerel is a good source of iron, vitamin B12, and folate, all of which are essential for preventing certain types of anemia. Including mackerel in your diet can help maintain healthy levels of these micronutrients and prevent anemia-related complications.
Reduced Risk for Type 2 Diabetes
A high intake of polyunsaturated fats, such as those found in mackerel, has been associated with a reduced risk of type 2 diabetes. Including mackerel in your diet can help improve glycemic regulation and overall metabolic health.
Allergies and Adverse Effects
It's important to note that fish allergies can cause severe reactions, including anaphylaxis. Some individuals may also experience histamine toxicity, particularly if the fish has spoiled. Symptoms of histamine toxicity can mimic those of a typical food allergy and may include wheezing, tongue swelling, diarrhea, faintness, and nausea. If you suspect an allergy to mackerel, it's recommended to consult an allergist for confirmation.
Pregnant and breastfeeding women should also be cautious about consuming certain types of mackerel, as some varieties can be high in mercury. It is recommended to follow the guidelines provided by the American College of Obstetricians and Gynecologists and avoid fish with high mercury levels. Raw or undercooked fish should also be avoided during pregnancy to prevent food poisoning.
Varieties, Storage, and Preparation
Mackerel can be found fresh or canned in most grocery stores. Canned mackerel is often packed in olive oil, which enhances its flavor. Atlantic mackerel is one of the more popular varieties.
When buying fresh mackerel, look for firm flesh, clear eyes, and a shiny body. Store raw mackerel on ice or in the refrigerator and cook it within 2 days. If you don't plan to use it immediately, wrap it tightly in plastic wrap and freeze it for up to three months.
Canned fish can be consumed past the best by date as long as the can is in good condition. Once opened, it should be eaten within 3–4 days.
Mackerel can be prepared in various ways. It can be added to salads, grilled, roasted with olive oil and lemon, or even cured with salt and rice wine vinegar. The mild flavor of mackerel pairs well with a variety of herbs and vegetables.
Smoked mackerel is a nutritious and flavorful fish that is high in protein, omega-3 fatty acids, and essential vitamins and minerals. Including mackerel in your diet can have numerous health benefits, such as improved heart health, reduced risk of cognitive decline, and prevention of anemia. However, it's important to be mindful of allergies and choose mackerel varieties with low mercury levels. Whether you enjoy it fresh or canned, mackerel is a delicious and healthy choice for fish lovers.
