GMO- Genetically Modified Organism
i think tomatoes were the first hit on the list and started in the 80s, a majority of our food today has been genetically modified. scary concept. i topic i go a little crazy on.
Fish are also now taking a hit i thing the latest i read were farmed Salmon, but the abstract was the risk of them being able to get loose, and the argument they already are.. ugh

the FODMAP idea is a very good one, and elimination of the things that hurt your insides. i have IBS and ongoing things with my guts with upcoming tests which may set the stage for more drastic changes for me as well.

Edit:
Organic generally is non gmo, usually this means not treated with chemical fertilizers/pesticides. many containers you see today will have the non-gmo certified little pic on it, its quite tiny with a green check mark and a small orange butterfly.
