It isn't difficult to examine the science reported to date, combine it with first principles, and have a pretty good idea if a scientific idea is correct or not. By the time regulators have overcome inertia and industry pressure and created a new regulation, the science has been there for a long time. As for the previously held view (now considered incorrect) that saturated fats are harmful, a similar review of the scientific results at any time over the past 40 years would have shown that the view was based on the flimsiest of actual data, like one correlation combined with a second correlation. That said, if you are relying on the government and other authorities as the final word on health advice, history suggests a bad outcome.
