A recent research study conducted by Karolinska Institutet offers scientifically grounded and useful insights for individuals with a family history of heart disease. Published in the Journal of the American Heart Association, this study clearly states that ‘Oily Fish Reduces Heart Disease Risk’.
Oily fish, such as salmon, mackerel, herring, and sardines, are abundant in omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These are essential fatty acids crucial for various bodily functions. Since our body cannot produce them, they must be obtained through diet. This study adds to the growing body of research underscoring the importance of omega-3 in our diets.

Focusing on the intersection of cardiovascular disease and diet, the study presents a compelling case for those with a genetic predisposition to heart disease. Researchers examined a range of cardiovascular conditions, including coronary heart disease and stroke. The insight is particularly crucial given the hereditary nature of cardiovascular disease, as explained by Karin Leander, a senior lecturer and associate professor at Karolinska Institutet.
Leander, who led the research, delved into the interplay between genetic factors and dietary habits. The study encompassed data from over 40,000 individuals without a history of cardiovascular disease. During the follow-up, nearly 8,000 participants suffered from heart-related illnesses. The analysis revealed that individuals with both a family history of cardiovascular disease and low levels of EPA/DHA faced an over 40 percent increased risk of heart disease. This risk was contrasted with a 25 percent increase for those with only a family history of the condition.
Leander emphasizes the potential benefits of oily fish consumption for those with a family history of heart disease. The objective measurement of EPA/DHA levels in the study participants underscored the reliability of the research, moving beyond self-reported dietary habits.
The study, a collaborative effort by the Fatty Acids and Outcomes Research Consortium (FORCE), involving over 100 researchers worldwide, analyzed data from 15 studies across 10 countries. It marks a significant advancement in understanding the relationship between family history, diet, and cardiovascular health. Funded by the Swedish Research Council and the Swedish Heart-Lung Foundation, the research stands conflict-free and represents a new frontier in dietary recommendations for heart disease prevention.
This study not only emphasizes the importance of omega-3 fatty acids in our diet, but also illuminates the precautions that individuals with a genetic predisposition to heart disease should take. Indeed, we should pay attention to including oily fish such as salmon, mackerel, and herring in our diet. Nevertheless, when buying such fish, it’s crucial to ensure that they are healthy options.
