Children’s diets in developed countries are on average low in fruits and vegetables and high in energy-dense, nutrient-poor (or noncore) foods, even at young ages (1–3). Suboptimal dietary intakes contribute to the development of overweight and obesity and are associated with chronic disease and comorbidities throughout the lifespan (4, 5). Additionally, diet patterns are likely to track across life stages (6) and diet quality appears to decline as children age (7). Efforts in nutrition promotion for obesity prevention should therefore commence in early childhood to set healthy dietary trajectories for life, as demonstrated by a number of studies currently underway (8–10).
