But what if GMO crops aren’t as nutritious as regular? Then even if there is less pesticide/herbicide used per calorie of yield there might be a net deficit in nutrients gained per calorie or per unit of pesticide/herbicide. GMO soybeans were found to contain less nutrients than regular soybeans. http://www.sciencedirect.com/science/article/pii/S0308814613019201 I’m not for GMO labeling because it is too widespread across crops and ingredients derived from them and because many are likely just fine. However I am for more longer term studies before crops are put into general use. Endocrine disrupters may affect generations, so a few generations of lab animals should be reared to assess affects on fertility and birth defect risks. We should not only look at acute short term risks for larger doses.
