Aspartame reminds me of homosexuality.
British philosopher Jeremy Bentham spent a great deal of effort trying to figure out a rationale, based on his utilitarianism, to make homosexuality illegal. He could find none. According to his principles, homosexuals must be treated like other adults, as basically free to do as they please so long as they do not harm others.
Sadly, Bentham would not allow his research and reasoning made public in his lifetime, for fear that it would tarnish the utilitarian emprise.
And here is the parallel story: Aspartame has been examined by scientists more than most other food substances.
They are always looking for a way to call it dangerous. And thus worthy of prohibition.
Aspartame’s like homosexuality: condemning it doesn’t pass muster.
Of course, the idea that you should ingest it no more follows than you should “be homosexual.” To each his/her own.
