WTF, dude? Not everything in life is about improving your rationality. Do you expect to become more rational after eating a hot dog? How about a peach?
I think you’re being a bit too skeptical here. Yes, I usually eat peaches because I like them and they’re good for my health. But I would, in fact, expect to become more rational after eating—especially if I was about to enter a supermarket to do my grocery shopping!
There is a difference between rationality (optimal decision making based on the known facts and a set of value-weightings of possible futures) and the value-weightings themselves. It strikes me that eating the peach would quite probably alter how much you would value particular possible worlds, but I find it much more difficult to believe that it would alter your ability to deal with complexity (predict the future).
