A long-term study of 76,000 people found that following the Nordic diet lowered overall death risk by 23%. The diet focuses on whole grains, fish, vegetables, and less processed food.
For many years, the Mediterranean diet has been the most famous healthy diet in the world. It is often linked to long life and a lower risk of heart disease.
The Mediterranean diet is known for foods like olive oil, fish, vegetables, nuts, and whole grains.
But new research suggests another diet may offer many of the same benefits.
It is called the Nordic diet.
A large study followed more than 76,000 men and women in Sweden for nearly 20 years. Researchers wanted to see how diet affected long-term health.
The results were impressive.
People who closely followed the Nordic diet had a 23% lower risk of dying from any cause compared with those who did not follow the diet.
They also had a lower risk of dying from heart disease and cancer.
Even more interesting, the benefit appeared even when people did not follow the diet perfectly. Simply eating healthier foods more often made a difference.
What Is the Nordic Diet?
The Nordic diet comes from the traditional foods eaten in countries like Sweden, Denmark, Norway, Finland, and Iceland.
The updated Nordic nutrition guidelines were released in 2023. They were designed with two goals:
• improve human health
• protect the environment
The diet encourages eating natural, minimally processed foods that grow well in northern climates.
Foods eaten more often include:
• whole grains like oats, rye, barley, and whole wheat
• vegetables
• fruits and berries
• legumes such as beans and lentils
• fish
• nuts and seeds
• low-fat dairy
Foods eaten less often include:
• red meat
• processed meat like bacon or sausage
• refined grains like white bread
• sugary foods and drinks
The overall idea is simple: eat mostly plant foods, add fish regularly, and limit processed foods.
Why These Foods Help Health
Each food in the Nordic diet plays an important role.
Whole grains
Whole grains are one of the most studied healthy foods. Research involving nearly 800,000 people found that each extra daily serving of whole grains reduced overall death risk by about 7%.
Whole grains contain:
• fiber
• magnesium
• B vitamins
• antioxidants
These nutrients help reduce inflammation and improve heart health.
Legumes
Legumes include foods like:
• lentils
• chickpeas
• beans
• edamame
They are rich in fiber and plant protein. They also contain resistant starch, which feeds healthy bacteria in the gut.
This may help improve blood sugar control and reduce inflammation.
Many studies link legumes to longer life.
Fish
Fish is a major source of omega-3 fatty acids.
These healthy fats help:
• lower inflammation
• improve heart health
• support brain function
Fatty fish such as salmon, herring, and mackerel are especially common in Nordic countries.
Less processed food
The Nordic diet also works by removing harmful foods.
Processed meats are strongly linked to colon cancer. The World Health Organization classifies them as a Group 1 carcinogen.
Added sugar and refined grains can raise blood sugar and increase the risk of obesity and diabetes.
Eating less of these foods improves metabolic health.
Nordic Diet vs Mediterranean Diet
The Nordic diet and Mediterranean diet share many similarities.
Both diets encourage:
• fruits and vegetables
• whole grains
• fish
• nuts and seeds
• legumes
• limited processed foods
Both diets are also linked to lower heart disease risk and longer life.
However, there are some differences.
Main fat source
Mediterranean diet
• olive oil is the main fat
Nordic diet
• rapeseed (canola) oil is more common
Grains
Mediterranean diet
• wheat and pasta
Nordic diet
• oats, rye bread, and barley
Fruits
Mediterranean diet
• grapes, citrus, tomatoes
Nordic diet
• berries such as blueberries and lingonberries
Dairy
Mediterranean diet
• dairy is eaten less often
Nordic diet
• low-fat dairy is commonly included
Sustainability focus
One unique feature of the Nordic diet is its strong focus on environmental sustainability.
Foods were selected not only for health benefits but also for their lower environmental impact.
Researchers considered:
• greenhouse gas emissions
• water use
• land use
This makes the Nordic diet both a health strategy and a climate strategy.
You May Already Be Eating This Way
You do not need to move to Scandinavia to follow the Nordic diet.
You may already be doing parts of it.
Ask yourself if you regularly eat:
• whole grain bread or oatmeal
• beans or lentils
• fatty fish
• vegetables
• fruit
• nuts or seeds
If you eat several of these foods each week, you are already moving in the right direction.
The most important lesson from the study was simple:
Health improves when the overall pattern of eating improves.
No one in the research followed the diet perfectly.
The benefits came from consistent healthy choices over time, not perfection.
