How fatty acids can protect the heart

Omega-3 fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential for various bodily functions. Their positive effect on heart health is often emphasised, especially in the prevention of cardiovascular disease. But how exactly do omega-3 fatty acids support the heart and what does science say about them?

Studies show that an increased intake of omega-3 fatty acids can reduce the risk of heart attacks. This is attributed, among other things, to the anti-inflammatory properties of EPA and DHA. Inflammation plays a key role in the development of arteriosclerosis, which increases the risk of heart attacks and strokes.
 

Omega-3 fatty acids can help to reduce these inflammatory processes and thus protect the blood vessels.

Another important factor in heart health is the heart rhythm. Cardiac arrhythmias such as atrial fibrillation increase the risk of serious heart problems. Research has produced mixed results and the effectiveness of omega-3 in this area has not yet been conclusively established.

In addition to their anti-arrhythmic properties, omega-3 fatty acids also help to lower blood pressure. High blood pressure is a key risk factor for cardiovascular disease. Studies suggest that omega-3 fatty acids can improve the flexibility of blood vessels and thus have a positive effect on blood pressure.

Although many studies show the positive effects of omega-3 on heart health, there is also research that shows no significant benefit of omega-3 supplements for cardiovascular disease. It is assumed that the effect depends on individual health, diet and other factors. Omega-3 should therefore be considered as part of a heart-healthy diet, not as a stand-alone measure.

Omega-3 fatty acids have been shown in many studies to have positive effects on the heart, particularly through their anti-inflammatory effect, lowering of blood pressure and their potentially stabilising effect on the heart rhythm. However, as the scientific results are mixed, the debate remains open. A holistic, healthy lifestyle is essential to optimally support the heart and omega-3 should be embedded in this.
