Frankly, I'm REALLY surprised that this wasn't an established scientific result.
There must be an awful lot of things which are very hard to prove in a proper controlled study, but which are totally obvious to anyone who tries them. To prove something about diet to everybody's satisfaction I'd have to get dozens of volunteers, compensate them properly for their time, carefully monitor what they eat, and worry about all sorts of experimental artifacts coming from the fact that they know they're taking part in a dietary experiment. As you can see in this thread, people are still complaining that this presumably-expensive experiment still doesn't really prove its point.
Alternatively, to prove it to my own satisfaction I can try it out for two weeks and see whether it works. And that's all I really care about.

The problem is lots of stuff that people think they know and is totally obvious is completely wrong and completely subjective. Science has a harder job, it has to prove things objectively.
