Genetically engineered bananas, packed with micronutrients, are to undergo their first human trial in the United States to test their ability to battle rampant vitamin A deficiency — a large cause of infant death and blindness throughout low-income communities around the world. The six-week trial is backed by the Bill and Melinda Gates Foundation.

By the end of the year we’ll be able to learn about the results of this trial, and if it’s successful, they’ll start growing such bananas in Uganda by 2020.

If these bananas are approved for growth in Uganda, other staple crops in Rwanda, Tanzania and Kenya could also be engineered with micronutrients, Time reports.
