Genetically Modified Foods And The Environment
Now that I have managed to alienate almost everyone, I should point out that there are some non-health issues around GMO foods. The biggest issue is that many of the genetically modified foods contain modifications that make them resistant to herbicides, and that encourages overuse of those herbicides with the resultant pollution of air, soil, and water.
Another concern is that the increasing reliance on genetically modified food crops is leading to a decrease in the genetic diversity of those crops, which could make them more susceptible to a new virus or pest in the future. This is a theoretical concern, but there is historical precedence for believing that it could happen.
Finally, laws that prevent subsistent farmers from saving their own seed for next season's planting is a major concern in Third World countries. But, that is more an issue of corporate greed than it is of genetic modification.
The Bottom Line:
What is the take-home lesson for you?
From a health perspective:
• Genetically modified proteins are likely to be a food allergy risk for some people, but we have no good data on how many people are affected by this kind of food allergy
• Genetically modified DNA is a theoretical concern because of the ability of intestinal bacteria to pick up pieces of DNA, but we have no evidence at present that this has actually ever caused a problem in people.
• With respect to sugars, oils, and other nutrients extracted from foods it makes no difference whether the food was GMO or non-GMO
From an environmental perspective:
• Genetic modifications leading to herbicide resistance are a significant environmental concern because it encourages overuse of herbicides.
• Lack of genetic diversity from the overuse of GMO food crops is a theoretical concern, but one with historical precedence.
