The population groups targeted in other papers are healthy infants and toddlers; adults; older people; and pregnant and breastfeeding women. The Draft for Consultation aims to provide up to date, evidence-informed policy advice and technical information for health practitioners working with children and young people (aged 2–18 years). This includes nurses, dietitians, doctors, nutritionists, health promoters and educators. The Draft for Consultation has been developed from the update and amalgamation of the Food and Nutrition Guidelines for Healthy Children (Aged 2–12 years): A Background Paper (1997) and the Food and Nutrition Guidelines for Healthy Adolescents: A Background Paper (1998). In recognition of the many influencing factors on the food choice of children and young people, some topics additional to these previous guidelines have been included. For example, new sections outline considerations for selected population subgroups, the influence of environmental factors on food choice, and related topics such as physical activity and oral health.
