I thought the sacred plants were corn, beans, squash (the three sisters) and tobacco? We should probably add the tomato to the list.
My guess is that most of the so called sacred plants have been genetically modified, but are still available in a non GMO edition. Marketing a product as non GMO seems to be in vogue.
The GMO blue tomato was developed in an effort to make a tomato fruit more healthy to eat. Lab results (UK) seem to indicate that this is true (some of the mice lived). The USDA has approved one such blue tomato for US consumption. So far, the USDA has not said we had to eat them.
I have no problem with current GMO products and research. However, when AI takes the helm, we could be in for a rough ride:)
