The multifaceted challenge of malnutrition Malnutrition should be dealt in all its forms (underweight, wasting, stunting and overweight, as well as micronutrient deficiencies and nutrition-related chronic diseases)
Percent low birth weightUNICEF/WHO estimates circa 2000(187 countries)
178 million children under 5 are stunted Prevalence of Stunting
Category of public health significance (anaemia prevalence) Normal (<5.0%) Mild (5.0-19.9%) Moderate (20.0-39.9%) Severe (≥40.0%) No Data 293 million children under 5 are anemic Source: WHO Global database on Anaemia, 2006

Integrated food and nutrition action • Inadequate foetal development • Lack of breastfeeding • Inappropriate complementary feeding • Child under nutrition • Low fruit and vegetable intake • High salt (NaCl) intake • Saturated fat and trans fatty acid intake • High blood pressure • High cholesterol • Overweight and obesity • Physical inactivity
Evidence based maternal nutrition interventions • All Countries • Iron folate supplementation • Maternal supplements of multiple micronutrients • Maternal iodine through iodization of salt • Maternal calcium supplementation • Interventions to reduce tobacco consumption or indoor air pollution • Specific Situational Contexts • Maternal supplements of balanced energy and protein • Maternal iodine supplements • Maternal deworming in pregnancy • Intermittent preventative treatment for malaria • Insecticide-treated bednets
Infant and Young Child Feeding • Protection, promotion and support of appropriate IYCF • Exclusive breast feeding for 6 months • Complementary feeding (need strengthening and support for use of local foods, food fortification, micronutrient supplementation) • Feeding of IYC in difficult circumstances (HIV, malnutrition, emergencies, LBW) • Health services • Baby Friendly Hospital Initiative • Pre-service education and in-service training • Maternity protection • Code of marketing of breastmilk substitutes • Monitoring and evaluation
ACTION AREAS • Supporting a healthy start • Ensuring safe, healthy and • sustainable food supply • Providing comprehensive • information and education • to consumers • Implementing integrated actions • Strengthening nutrition and • food safety in the health sector • Monitoring and evaluation • HEALTH CHALLENGES • Diet related noncommunicable diseases • Obesity in children • and adolescents • Micronutrient deficiencies • Foodborne diseases The European Food And Nutrition Action Plan
Action area 1Supporting a healthy start • Promote maternal nutrition and safe dietary habits • Protect, promote and support breastfeeding and timely, adequate and safe complementary feeding of infants and young children • Promote the development of school and pre-school nutrition and food safety policies
Action area 2Ensuring safe, healthy and sustainable food supply • Improve the availability of fruit and vegetables • Promote the reformulation of mainstream food products • Improve food supply and food safety in public institutions • Explore the use of economic tools (taxes, subsidies)
Action area 2Ensuring safe, healthy and sustainable food supply • Ensure that the commercial offer of food products is aligned to food-based dietary guidelines • Establish targeted programmes for the protection of vulnerable groups • Establish intersectoral food safety systems with a farm to fork approach
Action area 3Providing comprehensive information and education to consumers • Food-based dietary guidelines and food safety guidelines, complemented by physical activity guidelines • Public campaigns aimed at informing consumers • Appropriate marketing practices • Adequate labelling of food products
Action area 4 Integrated actions to address related determinants • Increase opportunities to perform physical activity • Reduce the consumption of alcohol • Ensure the provision ofsafe drinking water • Reduce environmental contamination of the food chain
Action area 5Strengthening nutrition and food safety in the health sector • Engage primary care staff in nutrition assessment and in the provision of diet, food safety and physical activity counselling • Improve the standards of service delivery for the prevention, diagnosis and treatment of nutrition related diseases • Improve the quality of nutrition services and food safety in hospitals
Action area 6Monitoring and evaluation • Establish national and international surveillance systems on nutritional status and food consumption • Establish monitoring and surveillance systems for microbial and chemical hazards in the food chain and foodborne diseases • Evaluate the impact of programmes and policies • Improve public and private research establishments
Why little progress? • Inadequate investments • Inadequate coordination among players • Inadequate coverage • Inadequate responses • Life course not addressed • Social determinants not considered

Scaling up on WHO strategic priorities WHO has a major responsibility for promoting healthy nutrition for all the world's people, through collaborative support to Member States, particularly in their national nutrition programmes, in partnership with other intergovernmental and nongovernmental organizations, and their related sectoral approaches. • Development and operationalization of integrated food and nutrition policies • Intelligence of needs and response • Development of evidence based programme guidance • Country-level advocacy and technical assistance
Nutrition Programme Guidance • Evidence-based nutrition policy making • Best practices for implementation • Effective nutrition interventions
