Really folks here is a company that has created GMO potatoes just to get rid of a few black spots on fried potatoes. Really? This is an issue? Are we really that shallow that we would eat GMO’s just to get rid of a black spot. My God. Here is the article that tells you more about this stuff.
On the face of it, the new potato varieties called “Innate” seem attractive. If you peel the brown skin off their white flesh, you won’t find many unsightly black spots. And when you fry them, you’ll probably get a much smaller dose of a potentially harmful chemical.
But here’s the catch: Some of the biggest potato buyers in the country, such as Frito-Lay and McDonald’s, seem afraid to touch these potatoes. Others don’t even want to talk about them because they are genetically modified organisms, or GMOs.
The potatoes aren’t yet on the market (more about that later). So to get a sneak peek at them I paid a visit to Michigan State University and its top potato breeder, David Douches.
Douches is a lean and focused man, in constant motion. He’s been working with potatoes for most of his adult life. It is, you might say, a committed but high-maintenance relationship.
Douches fell for the potato 32 years ago, when he was in graduate school. It seemed like “a beautiful plant to work with,” he says. It also feeds a lot of people. According to the International Potato Center, the potato is the world’s third-most-important food crop. “I felt that when I work on something like this, it could have a large impact,” Douches says.
He wants to make the potato just a little bit better. Unfortunately, the potato resists improvement.
The reasons lie in the genetic nature of this crop. It’s very difficult, using traditional breeding, to make gradual improvements in an established potato variety. Mating it with another variety produces tremendously varied offspring, the vast majority of them inferior to the variety that you were hoping to improve. It’s like trying to improve a really good poker hand by reshuffling the whole deck of cards and dealing again.
This is why Douches is so excited about these new potatoes: They’re just like a much-loved variety, but better. To demonstrate, he and his colleague Joseph Coombs are banging some potatoes around inside an ancient, rotating wooden drum.
This is a bruise test. They’re comparing two different varieties.
The first variety is russet Burbank, the most popular potato in America. It’s been widely grown for more than a century. The other potatoes are almost identical to russet Burbank, but the J.R. Simplot Co. of Boise, Idaho, has inserted some extra genes into them in the laboratory. These potatoes are called Innate russet Burbank.
The Simplot Co. chose the word “innate” because the new genes it inserted are actually modified versions of some genes that exist naturally in potatoes; they are innate to this species. But the inserted genes have a curious effect: They shut down a few of the potato’s original, natural genes. Scientists call it gene silencing.
We’re about to see the results. We peel some potatoes that went through the bruising barrel yesterday and lay them out on a table. The traditional russet Burbank potatoes are starting to show some evidence of bruising. Black spots are forming.
We see few bruises, by contrast, on the Innate russet Burbank potatoes.
There’s another difference that we cannot see. If we fry these potatoes, the Innate russet Burbanks will have less than half as much of a worrisome chemical called acrylamide.
Lots of foods — coffee, for instance — contain acrylamide. But when lab rats eat it, they’re more likely to get cancer. Studies have never shown a clear link between acrylamide consumption and cancer in humans, but the Food and Drug Administration still says that it’s a good idea to consume less of it.
