So a team of public health researchers from all over the U.S. and Ecuador decided to see just how much of an impact an egg a day could have. They published their results on Tuesday in the journal Pediatrics. The group traveled to a poor province in Ecuador, gathered up mother-infant pairs, and split them into two groups. One group gave their babies (aged six to nine months) an egg each day, while the other group gave no eggs. Researchers showed up at their houses to provide the eggs every week and used that visit to gather information about how the babies were doing. They took their weight and height, plus asked about any other medical problems the infants might be having. At the end of six months, they found the kids who ate eggs were significantly taller and larger. An eggy diet appeared to reduce stunting by 47 percent, and babies fed on the incredible edibles were 74 percent less likely to be underweight.
