Huevos: aprovechar su potencial para luchar contra el hambre y la malnutrición

Estimados miembros del Foro FSN,

A pesar de la creciente prevalencia de la obesidad y las enfermedades no transmisibles, la desnutrición continúa siendo un grave problema para muchos de los países más pobres del mundo. En África oriental y austral, África occidental y central y Asia meridional, más de un tercio de la población infantil padece retraso del crecimiento. De hecho, casi 151 millones de niños menores de cinco años aún sufrían esta falta del crecimiento en 2017. Para muchos de estos niños, este problema que arruinará toda su vida se inició en el útero de sus madres. Los alimentos de mala calidad son uno de los principales factores que contribuyen a la falta de crecimiento tanto en el útero como en los primeros años de vida, cuando los niños son especialmente vulnerables. ¿Qué alimentos deberíamos promover para cambiar estas cifras? ¿Y qué debemos hacer para facilitar el acceso de las poblaciones más pobres del mundo a los alimentos más nutritivos?

Un alimento humilde como el huevo parece ofrecer cada vez más una oportunidad práctica y eficaz para abordar estos problemas. Los huevos son casi proteína pura, de muy alta calidad. También proporcionan prácticamente toda la ingesta necesaria de vitamina B12 y colina para la población infantil. El contenido de ácidos grasos esenciales de los huevos puede ser de especial importancia durante el embarazo. A casi todo el mundo -con la excepción destacada del cinturón vegetariano de la India- le gusta comer huevos, y pueden producirse a precios que los hacen accesibles incluso para la población que vive en la pobreza moderada.

Desde que se publicó un estudio de referencia el año pasado (Iannotti, 2017), sabemos que la ingesta diaria de huevos puede mejorar notablemente el crecimiento lineal de los niños pequeños. La revista Maternal and Child Nutrition ha publicado un suplemento especial, que recopila abundante información adicional sobre el valor nutricional de los huevos y diversas maneras viables de aumentar el acceso a éstos.

El primer artículo incluido en el suplemento proporciona una descripción general del papel de los huevos en la nutrición materna e infantil así como datos actualizados sobre su consumo (Lutter et al., 2018), mientras que el segundo artículo resume cómo se utilizó el marketing social en un ensayo controlado aleatorio sobre la ingesta de huevos en una fase temprana del período de alimentación complementaria, para fomentar el cumplir la recomendación de consumir un huevo diario, así como para empoderar a los participantes y modificar las políticas en Ecuador (Gallegos-Riofrio et al., 2018).

El tercer y cuarto artículo analizan el impacto de una intervención controlada para fomentar la producción avícola en la diversidad alimentaria y al estado nutricional de la población infantil en Ghana (Marquis et al., 2018) y Zambia (Dumas et al., 2018), mientras que el quinto artículo recoge los éxitos y las lecciones aprendidas de un proyecto sobre la producción avícola en pequeña escala para aumentar la producción de huevos y su ingesta en el hogar en cuatro contextos africanos diferentes (Nordhagen y Klemn, 2018).

En el sexto artículo (Bartter et al., 2018) se presenta un enfoque novedoso consistente en utilizar las cáscaras de los huevos de las gallinas para mejorar la ingesta de calcio en las zonas rurales del África subsahariana, mientras que el séptimo describe modelos de negocio para la producción avícola en África oriental y la India (Beesathuni et al., 2018).

Las numerosas funciones, sistemas, desafíos y opciones para la producción avícola sostenible se analizan en el octavo artículo (Alders et al., 2018) bajo una perspectiva centrada en la salud del planeta y el suplemento se cierra con un artículo sobre cómo lograr el acceso universal a los huevos a través de la producción avícola a gran escala (Morris et al., 2018).

Aprovechando estos últimos estudios, nos gustaría invitarle a participar en una discusión sobre este importante tema. Su experiencia y conocimientos serán de gran valor para poner en práctica las conclusiones y sensibilizar a la población sobre el papel que pueden desempeñar los huevos en la lucha contra el hambre y la malnutrición.

  1. Para aumentar el acceso de las poblaciones más pobres del mundo a los huevos, ¿cuál debería ser el equilibrio adecuado entre producción en pequeña escala, producción comercial a gran escala y comercio a larga distancia? Si los países tienden progresivamente a la producción a gran escala, ¿cómo equilibramos el objetivo de mejorar la nutrición con la preocupación por los medios de vida de los pequeños agricultores?
  2. ¿Además de aumentar su disponibilidad y reducir su precio, cómo podríamos incrementar la demanda de huevos? ¿Podría proporcionar algunos ejemplos de iniciativas exitosas?
  3. ¿Cómo podemos mitigar las posibles consecuencias negativas de la producción de huevos a gran escala para el bienestar animal y las emisiones de carbono?
  4. ¿Qué deben hacer las diferentes partes interesadas (gobiernos, sector privado, mundo académico, organismos normativos) para acelerar el acceso a los huevos en las comunidades pobres?

Confiamos en que este tema le resulte interesante y esperamos recibir sus reflexiones y comentarios.

Con nuestros mejores deseos,

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.

Kindest regards,

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. The link to Hard Choices is: http://smallholderagriculture.agsci.colostate.edu/1028-2/

Thank you,

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.

Best regards
