Mackerels are considered some of the most nutritious fishes. They're an excellent source of protein, vitamins B2, B3, B6, and B12, and vitamin D. Their flesh is also full of minerals like copper, selenium, and iodine. Some of these fishes also contain good amounts of iron and vitamin B1.
As mackerels belong to the "oily fish" category, they're one of the best sources of omega-3s — good fats that keep your heart and brain healthy.
Another nutritional benefit of mackerels is that they have significantly higher amounts of good unsaturated fats than saturated fats — fats that increase your bad cholesterol. In fact, about 77% of the fat in mackerel is unsaturated.
There are many well-known health benefits of mackerel. As a rich source of vitamins, minerals, and good fats, these are some of the ways eating this fish could benefit you:
May boost heart health. The American Heart Association recommends eating at least two servings of fatty fish like mackerel per week. There's a reason for that. Mackerels, being oily fish, have high amounts of omega-3s. These good fats are known to reduce blood pressure and decrease the levels of cholesterol in your body. Studies have shown that those who eat mackerel regularly have lower blood pressure and less cholesterol in their blood.
Having lower blood pressure means your heart doesn't have to work too hard to pump blood. Similarly, less cholesterol leads to less fat buildup in the arteries of your heart. As a result, your heart will stay strong and face fewer problems.
Many prevent brain disorders. The omega-3s present in mackerel — particularly DHA (docosahexaenoic acid) — also play a big role in brain development. These fats control the release of chemical messengers in your brain, in turn helping to maintain brain function. Studies also show that consuming marine omega-3s — like those in mackerel — can reduce your risk of mental health issues like depression, bipolar disorder, and autism.
May strengthen bones. There are many nutrients in mackerels that can help to keep your bones healthy. The most vital one is vitamin D. This vitamin helps in the metabolism of phosphorus and calcium — two minerals your bones need to grow. Getting enough vitamin D can lower your risk of bone loss and fracture. Besides this vitamin, mackerel also contains copper and selenium — minerals needed for maintaining your bone density.
May help in weight loss. Mackerel has good amounts of healthy fats and proteins. Studies show that, compared to carbohydrates, fats and proteins are much more helpful in lowering your levels of ghrelin — the hunger hormone that increases your urge to eat. Moreover, as a high-protein food, mackerels can keep you feel full for a longer time. This may stop you from overeating and help you maintain your weight.
