An egg a day appears to help young children grow taller
An egg a day might help undernourished young children grow to a healthy height, according to a six-month study in Ecuador.
Whether soft or hard-boiled, fried or whisked into an omelette, eggs appeared to give infants a boost.
It could be a cheap way to prevent stunting, say researchers in the journal Pediatrics.
The first two years of life are critical for growth and development - any stunting is largely irreversible.
Too short for age
Poor nutrition is a major cause of stunting, along with childhood infections and illnesses.
According to the World Health Organization, 155 million children under the age of five are stunted (too short for their age).
Most live in low- and middle-income countries and health experts have been looking at ways to tackle the issue.
Lora
Iannotti and her colleagues set up a field experiment in the rural
highlands of Ecuador and gave very young children (aged six to nine
months) free eggs to eat to see if this might help.
Egg dinners
Only
half of the 160 youngsters who took part in the randomised trial were
fed an egg a day for six months - the others were monitored for
comparison.
The researchers visited the children's families every
week to make sure they were sticking to the study plan and to check for
any problems or side-effects, including egg allergy.
Stunting
was far less common among the egg treatment group by the end of the
study - the prevalence was 47% less than in the non-egg group, even
though relatively more of these egg-fed infants were considered short
for their age at the start of the study.
Some of the children in the control group did eat eggs, but nowhere near as many as the treatment group.
Lead researcher Ms Iannotti said: "We were surprised by just how effective this intervention proved to be.
"And
what's great is it's very affordable and accessible for populations
that are especially vulnerable to hidden hunger or nutritional
deficiency."
She said eggs were great food for young children with small stomachs.
"Eggs contain a combination of nutrients, which we think is important."
Balanced diet
Prof
Mary Fewtrell, nutrition lead at the Royal College of Paediatrics and
Child Health, said: "In a way, it is surprising that more research has
not been conducted using egg in this situation - although I know that in
some cultures, parents do not necessarily find egg to be an acceptable
early food mainly because of concerns about allergy.
"Egg is a
good nutritious complementary food that can be introduced as part of a
varied diet once the mother decides to start complementary feeding -
never before four months."
She said eggs should always be well cooked to avoid any potential infection risk.
The
WHO recommends mothers worldwide to exclusively breastfeed infants for
the child's first six months to achieve optimal growth, development and
health. After the first six months, infants should be given nutritious
complementary foods and continue breastfeeding up to the age of two
years or beyond.
The British Nutrition Foundation advised: "While
eggs are a nutritious food to include, it's very important that young
children have a variety of foods in their diets. Not only is this
necessary to get all the vitamins and minerals they need, but also to
allow them to become familiar with a wide range of tastes and textures.
"A
range of protein-rich foods should be provided when feeding young
children, which can include eggs but can also feature beans, pulses,
fish, especially oily fish, meat and dairy products."
