In modern agriculture, it is not possible to only spray weeds without spraying soy and corn crops. Glyphosate is therefore genetically modified (GM) to kill only weeds while at the same time enhancing the growth of crops. However, glyphosate does not readily penetrate the leaves of weeds and crops, and therefore is mixed with adjuvants that aid leaf penetration. For decades, nano particles (NPs) and specifically carbon nano tubes (CNTs) that readily penetrate leaves have been used as adjuvants allowing glyphosate to be carried to plant roots for more efficient absorption.
Upon human consumption of GM foods, most glyphosate and included NPs are rapidly excreted, but residues [1] remain in the human gut. Indeed, the important question of NPs in GM foods is the same as that of nanotechnology in general: Do NPs contribute to the wide range of health problems?
Donald Huber, the prominent critic of GM foods claims soil-borne plant pathogens are produced that do indeed harm human health, e.g., residents living close to sprayed GM soybeans fields in Argentina developed cancers and birth defects.
However, GM food proponents argue science is still looking for, but not found Huber’s pathogen to establish the causal link between glyphosate and human health problems.
Regardless, the question remains: Is there a causal link between NPs in GM foods and human health? ...read more>>>....
