Hans Biesalski, University of Hohhenheim "How Science and Partnerships Can Improve the Agricultural and Nutrition Value Chain"

  1. 1. How science and partnerships can improve the agricultural and nutrition value chain - towards delivering more nutritious foods for those in need. Institute of Biological Chemistry and Nutrition, University of Hohenheim, Stuttgart, Germany
  2. 2. Detection of micronutrient inadequacies and how to compensate? • Inadequate supply of micronutrients may have a strong impact on health and development in particular during pregenancy and childhood • Early detection of dietary gaps are necessary to optimize the diet and to avoid „hidden hunger“
  3. 3. Supply Symptoms No Subclinical/unspecific Clinical Hidden Hunger describes the inadequate supply with one or more essential nutrients (Vitamins, Minerals, Trace elements, Amino acids) Hidden hunger becomes „visible“ with the occurence of clinical symptoms
  4. 4. Reasons: Missing sources (Liver, Eggs, pro-vitamin A). Low stores at birth. Frequent diarrhoe (Zinc def.) 200 – 500 million children are vitamin A deficient. 5 million per year get blind. High mortality in the first 5 years of live (30-50%). How many children with inadequate intake?
  5. 5. S Decline of vitamin A status without biochemical signs and occurence of non-specific and specific symptoms Clinical consequences SYSTEMIC (unspecific) COMPLICATIONS Increased mortality due to infections Increase of anemia/ growth retardation OCULAR COMPLIKATIONS Nightblindness Ocular infections Keratomalacia-Blindness Vitamin-A-Status Somer A., Nature Med. 1997 Hidden Hunger and consequences?
  6. 6. How to improve the nutrition value chain with respect to miconutrients? • Biochemical data or clinical signs document a more or less severe deficiency of one or more micronutrients. • Prior deficiency signs an inadequate intake of micronutrients affects health and development • The composition of the diet and the micronutrient gaps should be elucidated before clinical symptoms of a deficiency occur!
  7. 7. Objectives for the developement of CIMI (calculator for identification of micronutrient inadequacy) Fast and easy analysis of micronutrient adequacy on basis of population specific food groups -> time and cost saving data collection and analysis Comparison of the results to the reference values including the classification of iron and zinc bioavailability Self-explanatory presention of the results -> visualisation of micronutient sources and deficits for health education purposes
  8. 8. Calculation of macro- and micronutrient intake classification of zinc and iron bioavailability is based on dietary pattern Program structureProgram structure Total intake and % of FAO/WHO recommendations of energy, protein, carbohydrates, fat, iron, zinc, vitamin A, ß-carotene, retinol equivalents (1:6 and 1:12 conversion factor) Food intake in grams per day of a limited number of food groups Electronic assessment of micronutrient inadequacies on a population level
  9. 9. Algorithm for iron Program structureBioavailability calculation Classification to 15%, 12%, 10% or 5% of iron bioavailability Software determines: % of total energy intake is accounted for all starchy stables % of total energy intake is accounted for protein from fish, eggs, dairy and meat % of total energy intake is accounted for protein from fish and meat … Electronic assessment of micronutrient inadequacies on a population level Algorithm for zinc Classification to high, moderate or low zinc bioavailability
  10. 10. Food survey data of target population Data of the Indonesian Socio Economic Survey taken among 68,800 public households in 2008 Program structureProgram development Micronutrient density of extracted food groups Calculation of average nutrient density per food group based on the typical food composition Electronic assessment of micronutrient inadequacies on a population level
  11. 11. Program structureCIMI data input Electronic assessment of micronutrient inadequacies on a population level
  12. 12. Program structureCIMI data input Electronic assessment of micronutrient inadequacies on a population level
  13. 13. Program structureCIMI data input Electronic assessment of micronutrient inadequacies on a population level
  14. 14. Program structureCIMI data input Electronic assessment of micronutrient inadequacies on a population level
  15. 15. Program structureIndonesian children 4-6 years: nutrition data Electronic assessment of micronutrient inadequacies on a population level
  16. 16. Program structureIndonesian children 4-6 years: results in tables Electronic assessment of micronutrient inadequacies on a population level
  17. 17. Program structureIndonesian children 4-6 years: results in ring diagrams Electronic assessment of micronutrient inadequacies on a population level Iron Zinc
  18. 18. Program structureIndonesian children 4-6 years: results in ring diagrams Electronic assessment of micronutrient inadequacies on a population level Vitamin A
  19. 19. Females 20 – 52 years
  20. 20. 118 Children 1 – 3 years 128 Females 20 – 40 years The distribution of the ratio of nutrient intake calculated by NS and CIMI Validation of CIMI using Nutrisurvey programm as a control
  21. 21. Average intake of nutrients calculated by NS and CIMI and number and % of indviduals below the threshold
  22. 22. The CIMI program can be used to for a rough estimation of micronutrient gaps in different age and sex groups in different income groups in different local dietary diversity in different threshold aproaches educate people how to compose a diet to reduce gaps uncover food or food composition related to a specific micronutrient The CIMI program will not calculate a risk for deficiency or a level of adequacy
  23. 23. Science and partnership to improve the nutrtion value chain Electronic assessment of micronutrient inadequacies on a population level Micronutrient gaps which, to several reasons, cannot be closed via optimization of the dietary pattern might be closed with fortified food or with food with improved bioavailability of one or more micronutrients. But We always must consider that a deficiency of a micronutient does not mean that only this isolated micronutrient is missing in the diet. It is the micronutrient containing food which is missing. Consequently all the other essential micronutrients within that food might be also missing. Treatment of the symptom (isolated defciency) might be misleading
