Scott Adams of Dilbert fame writes on his blog that science's biggest fail of all time is 'everything about diet and fitness':
I used to think fatty food made you fat. Now it seems the opposite is true. Eating lots of peanuts, avocados, and cheese, for example, probably decreases your appetite and keeps you thin. I used to think vitamins had been thoroughly studied for their health trade-offs. They haven’t. The reason you take one multivitamin pill a day is marketing, not science. I used to think the U.S. food pyramid was good science. In the past it was not, and I assume it is not now. I used to think drinking one glass of alcohol a day is good for health, but now I think that idea is probably just a correlation found in studies.
According to Adams, the direct problem of science is that it has been collectively steering an entire generation toward obesity, diabetes, and coronary problems. But the indirect problem might be worse: It is hard to trust science because it has a credibility issue that it earned. "I think science has earned its lack of credibility with the public. If you kick me in the balls for 20-years, how do you expect me to close my eyes and trust you?"

When this story was posted to slashdot, someone linked this interesting article:
Basically, it says that someone did present evidence that fatty foods make people fat (well, cause heart disease), but that the study was flawed. He cherry-picked the countries studied, etc...
And, then he got a job at the American Heart Association, and convinced the government to recommend that everyone cut back on fatty foods...
The alternative theory seems to be that carbs make people fat.

The scientific consensus is that too much food intake compared to the amount spent is making people fat. Also, a balanced diet is most likely better for us omnivores.
You can find outliers for/against any claim that a specific diet mix is good or bad. Those eating 100% fat or 100% carbs are not likely to stay around too long to keep objecting, though.
