What Defines a Healthy Nordic Diet?
Developed in collaboration with food experts and Nordic nutrition recommendations, the healthy Nordic diet is more than just a set of food rules; it's an eating pattern that prioritizes health, environmental sustainability, and regional identity. It is often compared to the Mediterranean diet due to its focus on whole foods, but uses locally-sourced Nordic ingredients and specific fat sources like canola oil. The diet is characterized by a high intake of plant-based foods, such as berries, vegetables, and whole grains, combined with regular consumption of fish and moderate amounts of dairy. This contrasts sharply with the typical Western diet, which is high in processed foods, sugar, and red meat.
Core Principles of the Nordic Diet
- Emphasizes Plant-Based Foods: Fruits, berries, vegetables, legumes, and whole grains form the foundation of the diet, providing abundant fiber, vitamins, and minerals.
- Focuses on Local and Seasonal Eating: Adopting seasonal, locally sourced foods reduces environmental impact and ensures peak freshness and nutrition.
- Prioritizes Fish and Seafood: Fatty fish, like salmon, mackerel, and herring, are key protein sources and provide anti-inflammatory omega-3 fatty acids.
- Includes Canola (Rapeseed) Oil: Canola oil is the main cooking fat, valued for its low saturated fat and high polyunsaturated fatty acid content, including alpha-linolenic acid (ALA).
- Incorporates Low-Fat Dairy: Low-fat fermented dairy products, such as skyr and kefir, are consumed in moderation.
- Restricts Red and Processed Meats: Red meat and poultry are consumed sparingly, and processed meats are minimized.
- Minimizes Processed Foods and Additives: The diet actively discourages added sugars, fast food, and foods with additives.
Foods and Nutrients in the NORDIET Study
The NORDIET study is a randomized controlled trial that investigated the effects of a healthy Nordic diet on cardiovascular risk factors in subjects with high cholesterol. The diet used in the study was specifically composed to meet Nordic nutrition recommendations and emphasized key food groups and nutrients. The study demonstrated that subjects on the Nordic diet had significantly higher intakes of fruits, vegetables, and fish, and lower intakes of meat, sweets, and alcohol compared to a control group.
Key Foods in the NORDIET Study
- Whole Grains: The diet included ample amounts of whole grains from rye, oats, and barley, consumed as porridge, dense bread, or pearled grains. The high intake of whole grains contributed significantly to the total dietary fiber and beta-glucan content.
- Fruits and Berries: Berries (especially lingonberries and bilberries) and fruits (apples, pears) were consumed in abundance, providing antioxidants and fiber.
- Fish and Eggs: Regular consumption of fatty fish (salmon, mackerel, herring) provided essential omega-3 fatty acids, while eggs were included in moderation.
- Vegetable Oils: Rapeseed oil was the primary added fat source for cooking and dressings, providing heart-healthy polyunsaturated and monounsaturated fatty acids.
- Legumes: A higher intake of legumes like peas and beans was observed in the Nordic diet group compared to the standard Swedish diet.
- Low-Fat Dairy: The diet included low-fat milk and fermented milk products, contrasting with higher-fat dairy staples sometimes found in traditional Nordic cuisine.
Nutrient Profile and Health Outcomes
Analysis of the NORDIET intervention group's nutrient intake showed a beneficial profile. The diet was low in saturated fat and sodium while being high in dietary fiber and polyunsaturated fats.
Comparison: Nordic Diet vs. Standard Swedish Diet (NORDIET Study)
| Food Group | Nordic Diet (NORDIET) | Standard Swedish Diet (SRP) |
|---|---|---|
| Fruits, Berries, Veg | Significantly higher intake (e.g., 807g/day vs. 382g/day) | Lower intake |
| Meat & Poultry | Lower intake (89g/day vs. 139g/day) | Higher intake |
| Fish & Eggs | Significantly higher intake (72g/day vs. 50g/day) | Lower intake |
| Sweets & Desserts | Lower intake (38g/day vs. 51g/day) | Higher intake |
| Fats & Oils | Higher vegetable fat intake (32g/day vs. 23g/day) | Lower vegetable fat intake |
| Dietary Fiber | Approximately twice the recommended intake | Lower, not meeting high fiber targets |
The study's results demonstrated significant health improvements, including lower total and LDL ("bad") cholesterol, reduced blood pressure, and better insulin sensitivity in participants following the Nordic diet. These outcomes indicate that the distinct nutrient profile, particularly the high fiber from whole grains and the healthy fats from fish and canola oil, plays a crucial role in reducing cardiometabolic risk factors.
Conclusion
The healthy Nordic diet, as detailed in the NORDIET study and broader Nordic Nutrition Recommendations, offers a powerful, research-backed framework for healthy eating. By prioritizing plant-based foods, locally sourced fish, and beneficial fats like rapeseed oil, it provides a diet rich in fiber, antioxidants, and anti-inflammatory omega-3 fatty acids. Its emphasis on sustainability and minimally processed foods not only benefits personal health by reducing cardiovascular risk and improving blood lipid profiles but also supports a healthier planet. The Nordic diet proves that nourishing and health-promoting eating patterns can be adapted to regional availability and cultural preferences without sacrificing flavor or nutrition.
