Commentary – emerging insights into diet quality and cardiometabolic disease

Cardiometabolic diseases constitute a complex spectrum of disorders that share common lifestyle-related risk factors, making them highly preventable through targeted interventions. In this context, nutrition has emerged as a primary modifiable determinant capable of reshaping the metabolic trajectory and reducing long-term cardiovascular risk. The landscape of nutritional science is undergoing a fundamental shift. For decades, research focused on the isolation of single nutrients—fats, sugars, or specific vitamins—as the primary drivers of metabolic health. However, the contemporary consensus, reflected in this Special Issue of Nutrition, Metabolism and Cardiovascular Diseases, emphasizes “diet quality” as a holistic construct.
