The objective of this poster is to portray how local foods can be used to create a nutrient adequate diet for young children. Data from the Ethiopian National Food Consumption Survey (FCS) of 1544 children of 12-23 mo of age in Amhara, Tigray, Oromiya and SNNP regions of Ethiopia were used. Average breast milk intake was assumed. Linear goal programming (Optifood developed by LSHTM in collaboration with WHO) was used to identify critical nutrients for which the local diet cannot fulfil requirements. Frequently consumed foods, average portion sizes, minimum and maximum number of servings per week, dairy milk consumption and breast feeding status were described in each region. Promising local foods and fortified foods that could contribute to micronutrient intake were identified. Findings revealed that the local diet can fulfil iron requirements in all regions but cannot fulfil zinc requirements in all regions, and calcium, niacin, and vitamin A requirements in some of the regions. Additional interventions will be required to fill these nutrient gaps. Abstract • Linear programming (Optifood) was applied to develop population specific local food-based CFR and to identify critical nutrients. • For the purpose of this presentation we only used food intakes of children 12-23 mo, in four regions .

Abstract
• Linear programming (Optifood) was applied todevelop population specific local food-based CFRand to identify critical nutrients.
• For the purpose of this presentation we only used food intakes of children 12-23 mo, in four regions . Results of younger children (6-8,9-11 mo) will be presented later.
• Data preparation Recipes were disaggregated in single ingredients Listed foods consumed by >3% of the target
population Identified average amount of reported intake of
each listed food by age group
• Improved local food-based complementary foodrecommendations can meet some of the nutrientrequirements of Ethiopian young children but shouldbe field-tested.
• RNI for iron is fulfilled for all regions.• However, even under the best circumstances, the
local diet cannot fulfil all nutrient requirements and additional interventions are required to fill the gaps.
• Zinc is a critical nutrient for all regions• Calcium, Niacin, and/or Vitamin A are critical
nutrients in some regions.

• Ensuring optimal Infant and Young Child Feeding(IYCF) practices has been identified as one of themost effective public health interventions toimprove child survival in developing countries.
• Appropriate complementary feeding should start atsix months of age with a focus on local foods, whilemaintaining breast feeding until at least 24 monthsof age (PAHO/WHO).
• There are no standard dietary recommendations forappropriate complementary feeding practices inEthiopia.

• To determine nutrient adequacy of young children’sdiet
• To formulate realistic, optimised food-basedcomplementary feeding recommendations (CFR) inthe four regions.

Methods
Developed assumptions for use in linear programming: reasonable minimum/ maximum weekly servings of each food
Staple food/snacks identified Food composition database reviewed and updated RNI for selected nutrients and target groups identified
Optifood• Set and check model parameters for target group
• Constraints on food pattern were set based on foods consumed by >3% of population,serving size and serving frequency.
• Used average body weight to determine thedaily energy requirements including energyfrom breast milk(BM). Average BM intakes andcomposition were taken from Brown andDewey (2003) and WHO/FAO 1998.
• All models are set to deliver 100% of energy requirements.
• Formulate nutritionally best diet and identify critical nutrients that remain low in the best diet.
• Identify nutrient dense foods.• Compare alternative Food Based
Recommendations(FBR), and choose the nutritionally best alternatives.

• Completed data available from 1544 children.• Portion sizes were small: 62-73% of consumed foods
were eaten in daily portion size of <15 grams. • Dairy milk was consumed in large quantities in each
region (10%consumed >126 grams in Tigray to 32% consumed >422 grams in Oromiya).
• Wheat was consumed in all regions but in moderate quantities (25 grams per day in SNNP to >100 grams in Tigray).
• Problem nutrients are those nutrients in the diets which fails to reach 100% of RNI in the best diets.
• No food pattern means the best diet that can deviate from average food pattern, but remains within the upper and lower food group constraints.
