The problem isn't science or the scientific method. It's marketers and salesmen (laypersons) that take one scientific study and go crazy with it. The studies themselves are probably littered with probabilities, statistics and caution conclusions. That doesn't work when you're trying to sell snake oil.
Just look at the whole anti-oxidant craze with cranberries, pomegranate and acai berries. Suddenly people are buying gallons of juice. The scientists didn't do that.

In most case; scientists are salesmen/marketers. They have to be because they're salaries come from grant money. There are plenty of examples of scientists themselves trumping things up.
