Roundup Toxin Accumulates in GM Soybeans

A study published in the journal Food Chemistry tested soybeans grown from seeds that were genetically modified (GM) to be resistant to the herbicide Roundup. It compared these with organic soybeans and soybeans from non-GM seeds.

The chemical and nutritional analysis of soybean samples from 31 different Iowa farms found the GM soy contained significantly higher levels of the toxin glyphosate, the central chemical in Roundup, than both the organic and the conventional non-GMO soybeans. The organic soybeans contained no glyphosate, plus significantly higher levels of protein and zinc, as well as lower levels of saturated fats.
