Яйца: использовать их питательный потенциал для борьбы с голодом и недоеданием
Dear all,
In spite of the increasing prevalence of obesity and non-communicable diseases, undernutrition remains a critical issue for many of the world’s poorer countries. In each of Eastern and Southern Africa, Western and Central Africa, and South Asia, more than a third of children are stunted. In fact, nearly 151 million children under five in the world were still stunted in 2017. For many of these children, the poor growth which will blight their entire lives began in their mothers’ wombs. Poor quality food is one major contributor to poor growth both in the womb and during the vulnerable first years of life. But which foods should we be promoting to make a difference to these figures? And how should we go about making the most nutritious foods accessible to world’s poorest populations?
The humble egg seems increasingly likely to offer a practical and impactful opportunity to tackle these problems. Eggs are almost pure protein, of very high quality. They also provide virtually the entire Adequate Intake, for young children, of vitamin B12 and choline. The essential fatty acid content of eggs may be especially important in pregnancy. Nearly the whole world—with the notable exception of the vegetarian belt of India—likes to eat eggs, and they can be produced at prices which make them accessible even to the moderately poor.
Since the publication of a landmark trial last year (Iannotti, 2017), we have known that daily consumption of eggs can markedly improve the linear growth of young children. The journal Maternal and Child Nutrition has now published a special supplement, which summarises a wealth of additional information on the value of eggs and feasible ways of increasing access.
The first paper provides an overview of the role of eggs in the diet of maternal and child nutrition and updated data on egg consumption (Lutter et al., 2018) while the second summarizes how social marketing was used in a randomized controlled trial of eggs early in the complementary feeding period to foster high compliance, as well as empowerment of participants and policy change in Ecuador (Gallegos-Riofrio et al., 2018).
The third and fourth papers examine how a controlled intervention to foster poultry production affected child dietary diversity and nutritional status in Ghana (Marquis et al., 2018) and Zambia (Dumas et al., 2018) while the fifth paper reviews successes and lessons learned from a project on small-scale poultry production to increase egg production and household egg intake in four diverse African contexts (Nordhagen & Klemn, 2018).
A novel approach to use chicken eggshells to improve dietary calcium intake in rural sub-Saharan Africa is reported in the sixth paper (Bartter et al., 2018), while the seventh paper reports on business models for poultry production in East Africa and India (Beesathuni et al., 2018).
The multiple roles, systems and challenges and options for sustainable poultry production through a Planetary Health lens are reviewed in the eighth paper (Alders et al., 2018) and the supplement closes with a paper on how universal access to eggs might be achieved through large scale poultry production (Morris et al., 2018).
Taking advantage of these latest studies, we would like to invite you to join a discussion around this important topic. Your experience and knowledge will be of great value to operationalize the findings and to raise awareness of the role that eggs can play in the fight against hunger and malnutrition.
- In order to increase access to eggs for the world’s poorer populations, what should be the right balance between small-scale production, large-scale commercial production, and long-distance trade? If countries do increasingly move towards large-scale production, how do we balance the interests of better nutrition with concerns about smallholder livelihoods?
- What are the different ways that we could increase demand for eggs, other than increasing availability and reducing price? What are some examples of successful initiatives?
- How can we mitigate the potential downsides of large-scale egg production on animal welfare and carbon emissions?
- What do we need different stakeholders (governments; private sector; academia; normative agencies) to do to accelerate access to eggs in poor communities?
We hope that you will find this interesting and look forward to receiving your thoughts and comments.
All the best

Where to start...
Those 9 articles do not teach us anything really new...
Not only are they not conclusive on the actual contribution of eggs to nutrition (what can be attributed to eggs vs. what can be attributed to SBCC?), they also show that egg production, unless done in an extensive manner, cannot really lead to cheap egg production, therefore to easy access for the poorest. This is rather convenient when the main partner for this discussion is one of the biggest lobby firm for the egg (and animal exploitation for food) industry.
Unfortunately, there is not much about animal welfare and on the trade off that the production of eggs on an industrial basis would mean for not only the environment but also for health. Let's not forgot the many scandals plegging the egg industry around the world and the number of people getting sick because of the need to produce always more.
Click on the link to the Canada International Egg Commission and check all their members... it is very telling on how eggs production need to make checking and their eggs (babies) a commodity that is fed with antibiotic and kept from seeing the light of day. Is this the model we want for Africa? Is this the model we want at all?
We can agree that egg provide important nutrients, but those can be found in many other non-animal based products that respect animals and the environment (to the exception of the B12 vitamin). So the real question here, knowing that eggs can only be made available to the masses through industrialisation and commoditization of animals, do we really need eggs to fight hunger and malnutrition? Really?
Hallo members,
I considered eggs (and beans) as accessible and affordable protein sources of protein for households, especially in rural areas where chicken are majorly kept in free-range or semi-free range systems.
Small-scale or large-scale really depends on the purpose of producing eggs; for home consumption or for the market. If for the market, then production must make economic sense to the farmer. In Nakuru and Western region of Kenya, the cost of chicken feed remains the biggest hindrance making local eggs unable to compete in the local market. For example, eggs from Uganda sells for as low as KSh 300 (USD 0.3), while eggs by local producers retail at KSh 340 (USD 0.34). The downside is quality. Consumers are not assured of quality bearing in mind the distances the eggs have travelled.
Local initiatives to tackle the feed cost issue include the use of locally available feed like sweet potatoes and cassava; foods that are largely shunned by people in favour of maize, rice and wheat. The tuber crops are planted off season have the primary maize crop has been planted. The available sweet potato varieties are drought tolerant and take shorter time – from 4 months. Even with this, protein sources for chicken feed remain expensive for farmers.
Indigenous and improved indigenous chicken breeds are popular with farmers, especially small-to-medium scale producers because they are hardy (resistant to diseases and can survive on locally available feeds), and they are they are dual purpose; kept for meat and eggs, something that farmers see as an advantage over the exotic breeds.
On increasing demand, finding creative ways to educate people on the nutritional benefits of eggs. I have seen farmers sell eggs to things like soft drinks for their children, which have lesser nutritional benefit compared to the sold egg. Together with this, In addition, increasing options for consume eggs at the home level makes is appropriate. At the moment, most households consume eggs as boiled or fried as a snack, used as a vegetable to accompany. For child nutrition, use with porridge or as an addition with other foods can increase demand and diversity of usage.
Generally, awareness creation and training of producers is the first level intervention to mitigate the downside of large scale production. This is factored into extension and advisory services as part of wider community development communication and outreach. Consumers can also contribute through buying of eggs from farms that treat their birds well. Consumer awareness through mass media tools like radio, television, agricultural shows and exhibitions, and now social media offer possible interactive and participatory channels. However, this can only happen where it is possible to trace the source of the eggs in the market. This can be handled through policy and enforcement at both national and county levels of government.

Stimulating Egg Demand through Upgraded Household-level Food and Nutrition Knowledge, Kano State Nigeria
Hello forum members,
Eggs are high potential food for improving maternal and child nutrition; that is if you know what it is, what it can do for you in terms of body nutrition and how to go about exploiting the egg potential. We are talking about egg and generally food knowledge and information something that is lacking among vulnerable household women who are mostly responsible for managing maternal and child nutrition at the household level in our part of the world.
One of the feasible options to increase egg demand particularly among grassroots communities in northern Nigeria; Sub Sahara West Africa is to intensify vocational training of household women on food commodities and nutrition. By tradition these category of women are shouldered with responsibility of feeding the family despite the fact that majority of them have little or none food and nutrition knowledge such that is required to make tangible impact. They don’t take good nutritional care of themselves, the babies, school children, adolescents and the aged in the family. There is a situation where head of the household is a poultry farmer producing eggs for sale only and not a bit of the egg is consumed in the household as it is mythically considered luxury that is meant only for the rich. Another sad story is of a rural-based pastoralist community that practice free-range poultry farming producing meat and egg with organic potential but they don’t consume the chickens and eggs, only to sell them while their pregnant women and underage children clearly move around with severe symptoms of chronic malnutrition. Both cases are clear testimony of food and nutrition illiteracy among grassroots communities which could be successfully tackled through learning by training. Training household women on how to differentiate egg recipes and diversify egg utilization especially for maternal and child nutrition holds significant promises for checking diet-related health conditions as well as improve business for upstream actors in the egg value chain.
Stakeholder involvement
Stakeholders such as GAIN et al. need to have direct connection with grassroots community effort in problem areas such as Kano state in Nigeria in order to provide constant guide that will align food and nutrition vocational training with national and international nutrition agenda. For example,
Food and Nutrition Vocational Center (FNVC) in Kano metropolitan is non-governmental not-for-profit adult education outfit that mobilizes household women most of them secondary school terminated and married with children now; train them on food entrepreneurship and organize them into food cooperative to promote community nutrition. Please see attached FEED program.
There are challenges but the success indicators are remarkable. Sustainable intensification of the successes is achievable by collaboration with government and agencies such as GAIN, SUN (scaling up nutrition) in areas of food cooperative management, next level nutrition training and community engagement to address maternal and child nutrition problems on wider scale.

I recently attended a World Bank seminar/webinar on nutrition which was largely promoting the need for an egg a day to prevent stunting in infants and toddlers. I academic side was well done, but was it practical? I doubt it. Most smallholder farmers and other deeply entrenched in poverty are unable to afford or produce. Please visit the webpage: http://smallholderagriculture.agsci.colostate.edu/integration-an-under-appreciated-component-of-technology-transfer/ where the example is used in a synthesized hypothetical case based on hard data from Angola, and also try working your way through the exercise on Hard Choice: Compromises in quality Nutrition and see if you can include the egg or sell the egg to acquire more energy to meet the dietary needs of you economic opportunity most likely based on heavy manual labor.

Dear Colleagues,
I agree with you that eggs are very important sources of amino acids, energy and also some essential trace elements and vitamins.
Recently, we finished some dose : response studies with various Iodine supply in laying hens and found interesting results, which may be also very helpful to contribute to overcome Iodine-deficiency in many countries.
Attached, you will find a review of these studies. E.g. Table 7 demonstrates that one egg of hens fed with adequate I-supply may cover about 50% of the human Iodine-requirements.
