Mother Jones has an article claiming that today’s veggies are much less nutritious than yesterday’s, owing to GM crops. The problem is that the original research (linked to by an editor after complaints) does not support this. They note that nutritional declines are only statistically significant in aggregate, yet the article quote individual measures. And they note that the culprit is likely the selection of strains for increased yields (i.e., feeding more people) rather than genetic modification.
This, my friends, is how disinformation gets out there.
