Ramalingaswami (1921 - 2001), Director (AIIMS) & Director General (ICMR) Main factors for good health and quality of life • Genetics • Nutrition • Mental well being • Physical activity and exercise • Avoidance of toxicants i.e. tobacco, alcoholic consumption and drug abuses • Environment: physical, biological, chemical, social, economic & political Nutrition is a link between food and health • Agriculture • Food supply • Service • • Food Food quality Food safety Nutrition • • • • Health • Promotion • Protection • Treatment Nutrient needs • Free from food Dietary intakes borne illness Nutrition wellbeing • Good health Nutrition literacy Food Security Food and Nutrition Education Food Culture Ultimate Goals: Nutrition Security and wellbeing for All Food and Nutrition Challenges • Continuing and persistent undernutrition Undernourished (Protein and energy deficiency) in children and adults Micronutrient deficiencies: of iron, iodine, vit. A and others • Overnutrition and diet related diseases Overweight & obesity Diabetes mellitus, high blood lipids, High blood pressure Cardio-vascular diseases Cancers • Food safety and quality Food and Nutrition Challenges • • • The pandemic of hunger and obesity, both are increasing FAO estimated in 2009 that over 1,000 million people were undernourished. Paradoxically, WHO estimated that 1,600 million adults are overweight and 400 million are obese.
