Omega-3 Fatty Acids: Key for Immune System and Metabolic Health

Omega-3 fatty acids, especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are essential fats that our body cannot produce on its own. A recent publication in Frontiers in Nutrition (Nunes EA et al., 2023) highlights their importance for the immune system and metabolism – a topic directly linked to Jürg Hösli's psychophysiological interaction model.

What Does Research Say?

The authors show that omega-3 fatty acids play a central role in what is known as immunometabolism. In summary:

• Inflammation Regulation: Omega-3 fatty acids have anti-inflammatory effects by reducing the production of pro-inflammatory cytokines and promoting the formation of inflammation-resolving molecules (resolvins, protectins).
• Metabolic Health: They improve insulin sensitivity and support mitochondrial function, which is crucial for energy metabolism.
• Immune System: Omega-3 positively influences the activity of immune cells such as macrophages and T-cells, offering protection against chronic diseases like diabetes or cardiovascular problems.

Connection to the Psychophysiological Interaction Model

Jürg Hösli's psychophysiological interaction model focuses on the connection between psyche, body, nutrition, and performance. Omega-3 fatty acids act as a link here: they not only influence metabolism and the immune system but also the balance of the autonomic nervous system. An anti-inflammatory effect reduces chronic stress at a cellular level, which in turn supports the sympathetic/parasympathetic balance. Furthermore, omega-3 fatty acids can modulate the cortisol axis – a central aspect of stress processing. A balanced immune system and efficient energy metabolism are essential to prevent stress from turning into overload.

Practical Relevance: What Does This Mean for Everyday Life?

The study results show that a targeted intake of omega-3 fatty acids is not only preventive but also therapeutically beneficial. Here are some concrete recommendations for action:

• Adjust Diet: Incorporate fatty fish such as salmon, mackerel, or sardines 2-3 times a week into your diet. Alternatively, plant-based sources like flaxseed oil or chia seeds can be used (albeit with lower bioavailability of EPA/DHA).
• Consider Supplementation: In cases of proven deficiency or high stress levels, high-quality omega-3 supplementation (at least 500 mg EPA/DHA per day) can be beneficial – ideally after consulting a specialist.
• Support Stress Management: Combine an omega-3-rich diet with relaxation techniques to enhance the anti-inflammatory effect.

Conclusion

Omega-3 fatty acids are more than just a dietary supplement – they are a building block for the G
