GMO Bananas Must Pass Their First Test

Volunteers in Iowa are getting a great deal — $900 for eating a banana. It’s part of a human feeding experiment to test genetically-engineered bananas.

Researchers hope that blood drawn from the volunteers will show higher levels of vitamin A, so the bananas can head to Uganda, where bananas are a staple and vitamin A deficiency is widespread.

NPR’s Dan Charles joins Here & Now's Meghna Chakrabarti to talk about the experiment, and what this may mean for fortified produce.
