While it is my personal belief that sodium cyclamate is safe for human consumption, (The US ban was due to a research study that linked consumption to an increase in bladder cancer of mice) you missed the point that I was making.
It is likely that both sides of the aisle have banned substances that are actually safe. It is likely that both sides allow substances that are harmful and should be banned. We should further review the areas in which we disagree as it is unlikely that the science changes across an ocean. It is much more likely that hidden incentives or bad methodology has lead to someone being incorrect. Whether you think the US or Europe is better or worse at food regulation is likely a biased opinion.
