Editorial: Nutrient density: evidence of multisectoral approaches for improved nutrition

Adequate nutrition is critical throughout the life course, to ensure survival, support growth and development, promote health and wellbeing, and prevent diseases, both infectious and non-communicable. While substantial evidence suggests that the public health burden of micronutrient deficiencies and inadequacies is highest in low- and middle-income countries (LMICs), a growing body of literature also highlights the widespread prevalence of micronutrient-related malnutrition in high-income countries (HICs), especially among population groups with increased nutritional requirements, such as infants and young children, adolescent girls, women of reproductive age, pregnant and lactating women, and older people.
