Eggs provide poverty alleviation
in developing countries
Eggs offer a lot more than simply a source of protein; they can play a
role in child development and poverty alleviation.
DR VICENT GUYONNET
On a visit to Zambia in 2011, I came upon an egg
carton that summarized perfectly what eggs are - and
can be - in terms of human nutrition.
The carton's very simple tag line
- "Protein for the nation" - was
spot on in a country where 54 percent
of the population lives below the
national poverty line (US$1.90/day)
and 40 percent of children under age
five have stunted growth, according to
data from the World Bank Group and
World Health Organization.
Simonga Farm, which produced the eggs and is
located near Livingstone, Zambia, along the mighty
Zambezi river, right above Victoria Falls, had identified
the true potential of eggs well before some of the most
promising research on egg nutrition and stunting reduction in children was even conducted. It was only in 2017
that Dr. Lora Iannotti published a study showing that
the daily consumption of one egg for a six-month period
by young children (6-9 months) in Ecuador significantly
reduced the prevalence of stunting by 47 percent and
underweight by 74 percent.
Value of egg protein
Why are eggs such a great source of proteins? Let's
go over a few reasons - some nutritional, some environmental and others societal.
Eggs can play a particularly important role in
meeting nutritional needs where access to food
and affordability are an issue. Dr. Vincent Guyonnet
The quality of proteins is based on their amino acid
composition and digestibility. Eggs provide the best
profile for essential amino acids, small protein-building
blocks which humans cannot synthesize and must find
in their diets.
Combined with a digestibility of 98 percent, eggs
have the highest biological value of any single food protein, a testimony of how efficiently these egg proteins,
after absorption, are able to convert into body tissues.
One 50-gram egg (edible portion) is able to meet
more than 50 percent of the recommended daily intake
for protein in young infants (7-12 months) and more
than 30 percent in children age 4-8. No wonder eggs can
Refrigerated eggs versus shelves: Is one method safer?
