1. Nutrition and food security some principles (cont)

3. Energy needs of population depend on: Resting metabolic needs (BMR) Activity: > 1.5 BMR Demographic composition –( includes pregnancy and lactation) Temperature E.g. emergencies 2100 kcals; usually around 2200 kcals; see RDAs

4. Energy needs: about 2200 kcals/hd/day, averaged over popn Protein: about 10% of energy should be from protein. CHO: 3.5-4.0 kcals/g Protein: 4.0 kcals/g Fat: 9.0 kcals/g

5. Nutrient types and deficiencies Type I - reduced tissue concentration and specific clinical signs Type II - reduced growth rate and non- specific signs

12. Household food security. Except in emergencies (and even then) interventions to improve food security are pretty much the same as those to reduce poverty. Relevant actions: –Macroeconomic adjustment –Employment policies –Employment provision –Agricultural policies –Food prices and subsidies, public distribution General subsidies Targeted Rations and quotas Food stamps and coupons See: ‘nutrition-relevant actions’ www.unsystem.org/scn www.unsystem.org/scn

13. Measure food security and hunger: FPI/CPI Income/exp surveys Food cons surveys (incl 24 hr recall) Food perception q’aires Anthropometry ? See FIVIMS meeting: http://www.fivims.net/documents/ISS/ISS_e/ISS_exesum.pdf http://www.fivims.net/documents/ISS/ISS_e/ISS_exesum.pdf
