Whole egg powder makes nutritious diet more affordable for Ethiopia: A cost of the diet and affordability analysis

Despite sustained nutrition education, consumption of animal source foods (ASFs) has been hindered by their low availability, accessibility and affordability. Drying eggs into powder can reduce transport/storage costs, increase shelf-life and allow easier dosage for use of smaller portions. This study aimed to evaluate the contribution of integrating egg powder to the nutrient adequacy and affordability of diets. Using the ‘cost of the diet’ analysis, we simulated the incorporation of egg powder into households' and children's diet and evaluated its contribution to the nutrient adequacy and affordability of diets. Analysis of the household consumption and expenditure survey (HCES 2016) revealed that only 0.2% of the total consumption expenditure was allocated for eggs, far below the 2.2% and 4.3% required to allow the consumption of one egg a day by the average and the poorest households, respectively. However, the minimum-cost nutritious diet required only 2.5 g of egg powder/person/day to reduce the cost of the optimized diet by 14% (0–24%), allowing an additional 1.2 million households (~4–6 million individuals) afford the optimized diet. The optimized diet for a child 6–23 months of age could be afforded by all households, except by those in the poorest wealth quintile. But, free distribution of egg powder to households in the poorest wealth quintile, if supplemented by effective nutrition education, can allow them to afford the minimum-cost nutritious diet for their 6- to 23-month child. The simple dehydration of egg into egg powder can have a substantial contribution towards increased egg consumption by increasing the affordability of the minimum-cost nutritious diet.
