Including for your children. At least according to Dr. A. E. Carrol:

As for me, I’m a big consumer of Diet Ocean Spray Cranberry Juice–I probably drink about a liter or two of it a day. It has Splenda in it. It’s one way I’ve kept my BMI (Body-Mass Index) in the normal range. It’s my compromise between water and drinking soda. I never drink soda or coffee–and rarely milk (my choice with cereal is unsweetened 30 calorie almond milk). And I don’t drink non-diet juices either. Mostly just water and the Diet Ocean Spray juices (there are a couple of varieties)–and occasionally herbal tea. Sometimes I drink wine (perhaps twice a week with dinner). That’s about it.
When I have a heavy hit of sugar, it’s in dark chocolate.
So I’m a huge bore. And will drop dead someday anyway. But that’s my current fluid consumption routine.
Prometheus Unbound 
Possibly not for the environment, however.
I don’t know about that angle. Hmm.
The scientific inquiries are somewhat incomplete; the biggest worry is that the unsweet sweeteners seem to pass right thru unfiltered/uneliminated to the water table by sewage processing and so forth! They aren’t sure what the effect is on animals, nature…and then, being IN water WE use again.
The law of unintended consequences will one day be the epitaph to our species.
It does make a person wonder, doesn’t it?
My personal recommendation is a heavy diet of endurance running, restricted sugar intake and two to three mugs of cocoa per day. No need for dark chocolate with its high sugar/fat levels.
