While this study is interesting, I definitely have issues with the statement the main researcher made, suggesting that this study means we should act to restrict high fructose corn syrup.
I think this paper has a lot of public health implications. Hopefully, at the federal level there will be some effort to step back on the amount of high fructose corn syrup in our diets.A real researcher would naturally be cautious and understand that this one study doesn't prove anything, as that's just not how science works. Science works by building a knowledge base in order to understand why these things are happening. One study, or even a handful of studies, doesn't prove anything. This study is just a building block of science, not an end result which demands immediate action.
The fact that they think we should take active steps based upon one study that didn't explain why this is happening would indicate that the researchers were biased and were attempting to find this exact result, in order to give us this exact conclusion. And that's just a bad way to do science, as it's too easy to devise a study to fit what you're looking for; even if that's not what you're intending to do.
Unfortunately, there's very little pure research done these days, as the easiest way to get funding is to set-out to prove a specific thing. If the sugar industry is funding you, it's because you were attempting to prove that sugar is safe. If an anti-diabetes group funds you, it was because you're proving sugar isn't safe. That's just how it works. That's not to say that these people are necessarily corrupt or anything, it's just that it's a perversion of science. Even well-meaning people can fool themselves into performing bad science, and if these researchers actually imagine that this one study should dictate public policy, they've probably engaged in bad science.
I mean, seriously, if their experiment showed that glucose cells grew more than fructose cells, would they have told us to drink more soda? I don't think so. They got the result they were looking for, and that's never a good thing.
