Nordic and Mediterranean diets linked to increased longevity and cellular health

New research highlights the longevity benefits of both the Nordic and Mediterranean diets. A study published in The American Journal of Clinical Nutrition suggests that following a healthy Nordic diet may reduce the risk of death from any cause by an estimated 6% over a 24-year period compared to no dietary intervention.

The Nordic diet emphasizes plant-based foods, fish, and unsaturated fats, utilizing regional staples such as canola oil, oats, rye, apples, berries, root vegetables, and fatty fish like salmon. This differs from the Mediterranean diet, which typically relies on olive oil, wheat, and citrus fruits.

In a separate study, researchers found that adherence to a Mediterranean-style eating pattern is linked to higher levels of mitochondrial microproteins, specifically Humanin and SHMOOSE. These proteins are associated with healthy aging, cardiovascular protection, and metabolic resilience. The study noted that higher consumption of olive oil, fish, and legumes, combined with lower intake of refined bread, was associated with elevated levels of these protective proteins.
