The latest news is that this French study found that rats fed a diet containing Monsanto’s genetically-modified corn consistently developed tumors and had overall worse health compared to other rats. The paper, available here, includes grotesque images of the large tumors the rats developed.

This study is clearly the most comprehensive yet performed in assessing the safety of a GMO food, as even critics acknowledge. However, the study has been criticized for having a small sample size, only 10 rats in the various experimental groups and another 10 in the one and only control group. That’s too small a number of rats in the control group, according to the critics, to tell for certain that it’s the GMO that caused the adverse health effects, since perhaps if there had been a comparable number in the control more of them might have had health problems too.

What mitigates against this criticism is that the rats in the experimental groups all did worse than the control group in almost every meaningful health measure tested. This clearly suggests that something other than chance is going on. But we don’t need to rely on this one study alone. This previous study is a meta-analysis of 19 studies testing the safety of GMOs, and their conclusion is that “Several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects… This was confirmed by our meta-analysis of all the in vivo studies published, which revealed that the kidneys were particularly affected, concentrating 43.5% of all disrupted parameters in males, whereas the liver was more specifically disrupted in females (30.8% of all disrupted parameters).”

You can also find a detailed description of the health problems that have been found to occur with GMOs in this paper, which lists, among other things: liver damage (including structural changes and atrophy), damage to DNA, kidney damage, enlarged pancreas, fewer digestive enzymes, double the normal death rate, alterations in sperm function, reduced fertility and infertility in the next generation, increased infant mortality and lower birth weight, increased rates of sterility and premature death in livestock fed GMOs, and evidence of the GMOs being or producing allergens.

Whether or not all this evidence is proof that all or most GMOs are unsafe is still open to some debate. But we mustn’t forget the important question that we should be asking: if I have a choice between two options, one of which is known to be safe and the other whose safety is in question, isn’t it prudent to choose the first option? That’s the Precautionary Principle, that I mentioned in my earlier post about organic food. With respect to GMOs, I’m going to be erring on the side of caution: since there’s no required labeling of GMOs (yet) I’m going to be choosing organic whenever I can (you hear that, Stanford?) 🙂 A little bit of inconvenience at the grocery store beats liver and kidney damage and becoming infertile, IMHO.

Interestingly, Monsanto was found guilty of chemically poisoning a French farmer, and an ingredient in its Roundup pesticide has been linked to birth defects (see this article). Monsanto doesn’t exactly have a great track record on health.

What do you think? I look forward to hearing from you!

This report by the world health organization looks at a number of different studies on acupuncture’s effectiveness, and comes to a positive conclusion. Worth noting is that the report recognizes that acupuncture is used for many different conditions; in the US, most people think acupuncture is only good for pain, which isn’t true. It has traditionally been used for a wide variety of conditions, not just pain but also things like digestive issues, menstrual problems, infertility, emotional problems, and so on.
