To be completely honest

> GM foods, with a goal of high yields, lost all nutritional value

sounds like unmitigated total bullshit.

If GM grains have zero "nutritional value" then why do tests show otherwise and why do people not die when they spend a year eating GM grain ?

Ag scientists measure nutritional value for all crops, GM and not GM, - how is possible they haven't noticed "zero nutritional value" results for GM grains?

Further:

   these data support the conclusion that GM events are nutritionally similar to conventional varieties of wheat, corn, and tomato on the market today.
