“…In contrast, the recipes prepared from maize and legumes or other cereal mixtures and legumes not only have higher Fe and Zn contents but also have considerably higher phytate contents. 14,15 The net effect in both cases is that they would not meet the theoretical mineral requirements of young children due to either their low mineral content or as a result of low bioavailability, unless enriched with animal source foods (ASF) or fortified with appropriate micronutrients. 6,16,17 As a result, the World Health Organization designates Ca, Fe, and Zn as "problem nutrients", and deficiencies of these minerals can lead to adverse health consequences and restricted child growth and development.…”

“…Among others, Ca, Zn, Fe, vitamin A and iodine deficiencies are common in Ethiopia, and have been attributed to low intake and low bioavailability (1,(3)(4)(5) . Moreover, the monotonous consumption of staple foods in complementary feeding fails to meet the daily requirements of infants and young children (6,7) . The assessment of nutritional status has been limited to anthropometry due to the time-and personnel-consuming nature of dietary assessments (8) .…”

Objective: Simple, cost-effective and convenient instruments like food groupbased scores are proposed to assess micronutrient adequacy of children in developing countries. We assessed the predictive ability and seasonal stability of a dietary diversity score (DDS) to indicate dietary quality of infants. Design: A 24 h dietary recall assessment was carried out on a sample of 320 and 312 breast-fed infants aged 6-12 months during harvest (HS) and pre-harvest (PHS) seasons, respectively, in Ethiopia. DDS was calculated based on seven food groups, while mean micronutrient density adequacy (MMDA) was calculated for eight micronutrients. Multiple linear regression models were used to assess the relationship between DDS and MMDA, and differences in nutrient intake between the two seasons. A receiver-operating characteristic curve analysis was performed to derive DDS cut-offs that maximized sensitivity and specificity of assessing dietary quality. Setting: The study was conducted in the catchment of the Gilgel Gibe Field Research Centre of Jimma University, south-west Ethiopia. Results: The mean (SD) DDS for HS and PHS was 2·1 (0·94) and 2·3 (1·1), respectively. The DDS was associated with MMDA (β = 0·045, P < 0·0001 in HS; β = 0·044, P < 0001 in PHS). A DDS of ≤2 food groups best predicted 'low' MMDA (<50 %) with 84 % and 92 % sensitivity, 36 % and 43 % specificity, and 47 % and 51 % correct classification for the HS and PHS, respectively. Conclusions: DDS is predictive of dietary quality of breast-fed infants. The study supports the use of DDS to indicate inadequate intakes of micronutrients by breast-fed infants in different seasons. Keywords Ethiopia Dietary diversity Micronutrient density adequacy Breast-fed infantsEthiopia has one of the highest rates of child malnutrition (1) . The nutritional status is influenced by many interrelated factors (2) . Among others, Ca, Zn, Fe, vitamin A and iodine deficiencies are common in Ethiopia, and have been attributed to low intake and low bioavailability (1,(3)(4)(5) . Moreover, the monotonous consumption of staple foods in complementary feeding fails to meet the daily requirements of infants and young children (6,7) . The assessment of nutritional status has been limited to anthropometry due to the time-and personnel-consuming nature of dietary assessments (8) . As a result, an intake assessment of nutrients, single food items or a combination of foods to predict the risk of one or more health-related problems has emerged as an alternative approach to actual quantification of nutrient intakes (9) .However, the problem of diagnostic ability of several dietary indices to predict health outcomes, dietary quality or nutritional status has not been resolved for some reasons (9) .The dietary diversity score (DDS) is a simple indicator of dietary diversity and is based on measuring the number of food groups consumed over a given reference period. A higher dietary diversity is associated with an adequate intake of essential micronutrients. The score has been shown to be ass...

“…In addition, as a cash crop, both the grain and straw of tef fetch higher prices than the respective products from other cereals. Consumers prefer tef not only because it makes good quality ''injera'', a pancake-like soft bread, but also because it is nutritious due to its high protein and mineral content (Bultosa et al 2002;Abebe et al 2007). Furthermore, the absence of gluten (Spaenij-Dekking et al 2005) makes tef an alternative food for people suffering from celiac disease.…”

Indigenous crops also known as orphan crops are key contributors to food security, which is becoming increasingly vulnerable with the current trend of population growth and climate change. They have the major advantage that they fit well into the general socio-economic and ecological context of developing world agriculture. However, most indigenous crops did not benefit from the Green Revolution, which dramatically increased the yield of major crops such as wheat and rice. Here, we describe the Tef Improvement Project, which employs both conventional-and molecular-breeding techniques to improve tef-an orphan crop important to the food security in the Horn of Africa, a region of the world with recurring devastating famines. We have established an efficient pipeline to bring improved tef lines from the laboratory to the farmers of Ethiopia. Of critical importance to the long-term success of this project is -018-2115-5 the cooperation among participants in Ethiopia and Switzerland, including donors, policy makers, research institutions, and farmers. Together, European and African scientists have developed a pipeline using breeding and genomic tools to improve the orphan crop tef and bring new cultivars to the farmers in Ethiopia. We highlight a new variety, Tesfa, developed in this pipeline and possessing a novel and desirable combination of traits. Tesfa's recent approval for release illustrates the success of the project and marks a milestone as it is the first variety (of many in the pipeline) to be released.
