There’s a new superbug in town, a superbug of a different kind. And Monsanto, the biotechnology giant, is the company behind it. It seems that one of Monsanto’s biggest money-makers—Bt corn, is creating superbugs. The majority of non-organic corn planted in the U.S. is genetically modified to produce a toxic compound against western corn rootworms—a major corn pest. This corn is well-known as Bt corn, because it contains a gene from the soil microorganisms Bacillus thuringiensis (Bt), which produces an insecticide against the corn rootworm.
Genetically modified Bt corn worked so well against the corn rootworm that some farmers began planting it every year, instead of the usual rotation of growing corn one year and soybeans the next—a method that helps reduce pest populations. If there is one thing that farmers should know, it’s that planting the same thing every year is a recipe for disaster (even if it doesn’t seem that way at first).
It turns out the corn rootworms, much like the superbug bacteria infecting humans, are developing a resistance to the Bt toxin that usually destroys the pest. A few farms in Iowa are reporting that the Bt corn no longer kills the corn rootworm, meaning the bugs—now superbugs—have developed resistance to the Bt toxin. First superbugs in our guts, now superbugs on corn, soon superbugs everywhere.
It’s estimated that about one-third of all the corn grown in the U.S. is Monsanto’s Bt corn. Try to buy products using organic corn, or at least non-GM corn, to avoid being part of the human experiment that is the consumption of GM foods in this country. We just don’t know if they’re safe yet, and many studies suggest they’re not.
By now many of you have heard about the remarkable health benefits of probiotics. In fact, the good-for-you bacteria seem to be making headlines everywhere these days—especially as we head into another cold and flu season. And as awareness increases about just how good probiotics are for optimal digestion and immunity, there’s another “p” word you might be wondering about: prebiotics.
In technical terms, prebiotics are often defined as “non-digestible food ingredients” that promote the growth of healthy bacteria in the digestive tract. So what does that mean? Quite simply, prebiotics are a food source for probiotics. So as they travel through the digestive system, they nourish all those good bacteria along the way and help them grow and multiply. The result? More good bacteria in the gut, which means better digestion and a stronger natural defense system.
So where do prebiotics come from? Well, mostly from soluble fiber sources such as oats, legumes, flax and almonds—and that’s where the “non-digestible” part comes into play. Dietary fiber—including both soluble fiber and insoluble fiber—really just refers to the parts of plant foods that our bodies are unable to digest and absorb, which is why it’s sometimes called “roughage”. Because prebiotics are not digested, they remain in the digestive tract where they can do their job of feeding their probiotic partners.
In addition to obtaining prebiotics through the diet, nowadays many probiotic supplements will actually include prebiotics to help you get the benefit of this dynamic duo (i.e. probiotics and prebiotics). For example, you may see something called FOS on the label. Short for fructooligosaccharide, FOS is extracted from soluble fiber foods such as chicory root and will help to feed and stimulate the growth of beneficial probiotic bacteria such as Bifidobacteria and Lactobacilli.
So there you have it! Two powerful “p” words that can go a long way toward better digestion and a stronger natural immune system—talk about a winning combination!
