No long term effects of GMO consumption: a review article by Snell et al…

Here is a new and excellent review article by Snell et al (2011) entitled “Assessment of the health impact of GM plant diets in long-term and multigenerational animal feeding trials” recently published in Food and Chemical Toxicology. Contrary to popular beliefs, long term studies HAVE been conducted on GMO consumption and they show NO LONG TERM effects.  The Snell et al article reviews outline several studies examining effects GM lines of maize, potato, soybean, rice and triticale.  The studies in question are of two types:

– 12 long term toxicological studies, where feeding time exceeds well over (up to 2 years) that of the 90 day studies classically used in toxicological studies applied to GMOs

 – 12 studies whose duration extended over several generations of animals.

KEY TAKEAWAY: “These studies by public research laboratories do not reveal any safety problem linked to long term consumption of GMO-derived food.” M. Kuntz  (For more interesting insights, I invite you to check out Marcel Kuntz’s website  Kuntz is a co-author on the Food and Chemical Toxicology article.)
