I haven’t yet written extensively about this (yet) but I did put out a short video on GMO vs non-GMO soy.
Unfortunately, the non-GMO crowd (powered by massive organic companies) knows that fears are easy to instill and hard to shake. The public has been fed fear-based messages that are not rooted in science.
The reality is that with all chemicals, the dose makes the poison. Whether it’s alcohol, carbon dioxide, or vitamin D, there are safe doses and toxic doses. Yet, the public has been led to believe that toxicity is black and white and that we should do whatever it takes to avoid a single drop at all costs.
Glyphosate has been extensively used for decades and we have a massive body of data to drawn on in defining the safe limits. National and international bodies have used these data to set conservative safe limits, on the order of 0.5 mg/kg body weight per day. The glyphosate levels we see in GMO crops, though higher than non-GMO, are still FAR FAR below the safe limits. You would have to consume nearly impossible amounts of GMO soy to even approach them (e.g. 16 cups of soy milk every day or 4 standard package of tofu, in my case).
In light of this science, it strikes me that worrying about the harms of GMO soy is like worrying about X-rays when you climb a mountain or fly.
At the same time, I want to be clear that I haven’t educated myself enough to speak confidently to the ecological differences between GMO and non-GMO soy. My initial research has focused on human health concerns because I am passionate about helping people make decisions rooted in facts, not fears.
