The study examined sets of twins in Malawi. Seven percent of the pairs of twins studied included a healthy twin and a malnutritioned twin, even though both were fed the same diet.
Through the course of the study, scientists
discovered that those children with kwashiorkor also had a particular gut bacteria
that, when combined with a very basic diet, caused malnutrition in mice. This bacteria inhibited the creation of
certain amino acids that the human body cannot make by itself.
