Researchers 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.
Watafiti walianzisha jaribio la uga katika nyanda za juu za mashambani za Ekuado na kuwapa watoto wadogo sana (wenye umri wa miezi sita hadi tisa) mayai ya bure ili kuona kama hii inaweza kusaidia.
