Folks at High Risk of Heart Disease May Gain From Eating Mackerel, Tuna
Enhancing Heart Health Why Mackerel and Tuna Are Beneficial for Those at High Risk of Heart Disease
High-risk individuals may benefit from eating mackerel and tuna to prevent heart disease.
Folks with a family history of heart disease might benefit from adding more oily fish like salmon, mackerel, herring, and sardines to their diet, according to a new study. Not only are these fish delicious and packed with nutrients, but they also contain high levels of omega-3 fatty acids. These fatty acids, which cannot be produced by the body and must be obtained from the diet, have been linked to numerous health benefits, including a stronger immune system, reduced inflammation, lower blood pressure, and improved cholesterol counts.
But here’s the twist: the study found that people with low levels of omega-3 fatty acids and a family history of heart problems had their risk of heart disease increased by more than 40%. On the other hand, if a person already had adequate levels of omega-3, their family heart history only increased their risk by 25%. This suggests that healthy habits, such as eating plenty of oily fish, can actually outweigh genetic risk factors in some cases. Talk about turning the tables on your genetic destiny!
“The study suggests that those with a family history of cardiovascular disease have more to gain from eating more oily fish than others,” said lead researcher Karin Leander, an associate professor of epidemiology at the Karolinska Institute in Sweden. So if you come from a long line of heart-related issues, it’s time to reel in some mackerel and sardines!
To arrive at these findings, Leander and her colleagues analyzed data from over 40,000 people, with nearly 8,000 of them experiencing heart problems like angina, heart attack, cardiac arrest, and stroke. They measured the levels of omega-3 fatty acids in each participant’s blood, which provided a more reliable indication of their dietary intake of oily fish compared to self-reported data.
“The fact that the measurements of fatty acids in blood and tissue are objective, as opposed to self-reported data on eating habits, is an important advantage,” Leander noted in a news release from the institute. So if you think you can fool yourself or your doctor into believing that you’re eating enough fish, think again. The blood doesn’t lie!

What’s even more fascinating is that the study hints at the intricate dance between our genetics and our environment. While cardiovascular disease does have a hereditary component, it’s not solely determined by our genes. As Leander explained, “A strong hypothesis is therefore that it is a combination of genetics and environment.” So rather than resigning ourselves to the whims of our DNA, we have the power to influence our health outcomes through lifestyle choices.
Next time you’re in the supermarket, don’t just rush by the seafood section. Take a moment to appreciate those silvery mackerel and shimmering sardines. They may hold the key to defying your family’s heart history. And who knows? Maybe your future self will thank you for making those small, but oh-so-tasty, dietary changes.
