Many people enjoy nuts – as a snack, in muesli, or as a source of plant-based protein. But did you know that not all nuts are equally healthy? The key difference lies in the ratio of omega-3 to omega-6 fatty acids . Here's why this is important and which nuts you should eat daily and which only occasionally – scientifically based and easy to understand.

What are Omega-3 and Omega-6? – The biochemical basis
Two sides of the same coin
Omega-3 and omega-6 fatty acids belong to the group of polyunsaturated fatty acids . Biochemically, they differ in the position of the first double bond:
Omega-3 : at the third carbon atom position
Omega-6 : at the sixth carbon atom position
Both are essential , i.e. vital for survival, but cannot be produced by the body itself .
The most important representatives
group | name | Characteristic | Happen |
Omega-3 | ALA | Plant-based, precursor to EPA & DHA | Walnuts, flaxseeds |
Omega-3 | EPA | Anti-inflammatory | Fish, algae |
Omega-3 | DHA | Important for brain, nerves, cell membrane | Fish, algae |
Omega-6 | LA | Mainly pro-inflammatory | Sunflower oil, nuts |
Omega-6 | Arachidonic acid (AA) | Prostaglandins, leukotrienes (inflammation) | Meat, eggs |
Why the ratio matters – inflammation, cell membrane, aging
Evolutionary balance disturbed
Our ancestors had a ratio of 1:1 to 1:4 (omega-3 to omega-6) . Today, it is often between 1:15 and 1:30 . This imbalance is biochemically problematic.
Inflammatory processes & eicosanoids
Omega-6 → prostaglandins & leukotrienes = pro-inflammatory
Omega-3 → Resolvins & Protectins = anti-inflammatory
If the omega-6 content is high, the conversion of ALA to EPA/DHA is blocked.
Effects on cells & aging
Cell aging : Omega-6 → more ROS, MMPs; Omega-3 → stabilizes cell membrane
Brain & Psyche : DHA deficiency correlates with cognitive deficits
Immune system : Omega-3 regulates immune balance, Omega-6 can overactivate
Cardiovascular system : Omega-3 reduces the risk of arrhythmias, Omega-6 promotes thrombosis

Ratio (O3:O6) | Meaning |
1 : 1 to 1 : 4 | 🟢 Ideal – corresponds to the human evolutionary profile |
1 : 5 to 1 : 10 | 🟡 Acceptable – slight tendency to inflammation possible |
> 1 : 15 | 🔴 Unfavorable – promotes silent inflammation & cell erosion |
> 1 : 25 | ⚠️ Critical – often with fast-food diets, risk for chronic patients |
Tip: If you regularly consume walnuts, linseed or algae oil and at the same time reduce omega-6 rich oils (e.g. sunflower oil), you can improve your ratio within a few weeks.
Nuts in comparison – The big omega fatty acid table
Type of nut | Omega-3 (g) | Omega-6 (g) | Ratio O3:O6 | Evaluation |
Walnuts | 9.1 | 38.1 | 1 : 4.2 | ✅ Very good – inflammation modulating |
Macadamia nuts | 0.2 | 1.3 | 1 : 6.5 | ✅ Good – overall low in Omega-6 |
Pecans | 0.5 | 20.6 | 1 : 41 | ⚠️ High in Omega-6 |
Almonds | 0.0 | 12.1 | — | ❌ No significant Omega-3 |
Cashew nuts | 0.1 | 7.8 | 1 : 78 | ❌ Very unfavorable |
Hazelnuts | 0.1 | 7.8 | 1 : 78 | ❌ Very unfavorable |
Pistachios | 0.3 | 13.6 | 1:45 | ⚠️ High in Omega-6 |
Brazil nuts | 0.0 | 18.0 | — | ❌ No Omega-3 |
pine nuts | 0.1 | 34.1 | 1 : 341 | ❌ Very rich in Omega-6 |
Peanuts | 0.0 | 15.6 | — | ❌ No Omega-3 |
Conclusion & practical tips for everyday life
Many people underestimate the impact of the fatty acid composition in their daily diet. While nuts are considered healthy, a closer look reveals that the omega-3 content—and especially the ratio to omega-6—makes the decisive difference. Walnuts provide anti-inflammatory alpha-linolenic acid (ALA), while other varieties tend to be more pro-inflammatory. Choosing the right varieties can actively counteract silent inflammation, cardiovascular problems, and even the signs of aging.
The good news: Even small daily changes—like swapping peanuts for walnuts or sunflower oil for olive oil—can improve your omega ratio in just a few weeks. Combined with high-quality sources of EPA and DHA (e.g., algal oil), you can create an anti-inflammatory foundation for increased energy, better cellular health, and mental clarity.
Practical tips at a glance:
Walnuts are the best plant-based source of Omega-3 – a small handful a day is enough.
Macadamia nuts are recommended despite their low omega-3 content because they contain extremely little omega-6.
Nuts such as cashews, hazelnuts, pistachios, peanuts should be reduced if you have inflammation problems.
The omega ratio can be significantly improved by combining walnuts, flaxseed, algae oil and reducing omega-6 sources .
💡 Coaching integration possible? Yes
Recommendation for coaching module:
Breakfast: 10 g flaxseed + 5 walnuts
Lunch: Vegetable dish with 1 tablespoon olive oil instead of sunflower oil
Evening: No fast food, but 1 tablespoon of algae oil as a source of DHA
