Healthy childhood development hinges on balanced dietary patterns, and pediatric nutrition and wellness encompass more than caloric needs—they address holistic well-being. From infancy through adolescence, nutritional strategies must evolve to support physical growth, cognitive function, and emotional health. Pediatricians now screen for food insecurity, eating disorders, and micronutrient deficiencies as part of routine care. Conditions such as obesity, type 2 diabetes, and food allergies necessitate personalized nutrition planning and lifestyle interventions. Pediatric nutrition and wellness also incorporate education on physical activity, screen time, and sleep hygiene. Integrative approaches, including culturally sensitive dietary counseling and behavioral support, are gaining traction. As public health concerns about childhood nutrition grow, evidence-based strategies are vital to instilling lifelong habits that prevent chronic disease and enhance quality of life.
