The marketing of high-calorie, low-nutrient foods and beverages is linked to overweight and obesity. A major 2006 report from the Institute of Medicine (IOM) documents evidence that television advertising influences the food and beverage preferences, requests, and short-term consumption of children aged 2-11 (IOM, 2006). Challenges and Opportunities for Change in Food Marketing to Children and Youth also documents a body of evidence showing an association of television advertising with the adiposity of children and adolescents aged 2-18. The report notes the prevailing pattern that food and beverage products marketed to children and youth are often high in calories, fat, sugar, and sodium; are of low nutritional value; and tend to be from food groups Americans are already overconsuming. Furthermore, marketing messages that promote nutrition, healthful foods, or physical activity are scarce (IOM, 2006). To review progress and explore opportunities for action on food and beverage marketing that targets children and youth, the IOM's Standing Committee on Childhood Obesity Prevention held a workshop in Washington, DC, on November 5, 2012, titled "New Challenges and Opportunities in Food Marketing to Children and Youth."
