Soft drinks regardless of whether they are sweetened with sugar or artificial sweeteners cause all sorts of health problems including but not limited to obesity, diabetics, heart problems, cancers etc.
I voted for Ring Confidential Transactions. The health impact of this is to stimulate the brain while learning how they work, with all sorts of beneficial health results.
I would agree with the problems you mentioned about sugared soft drinks but I don't believe the evidence for what you claimed about artificially-sweetened soft drinks. I think those are way better than the sugared drinks and I think the cancer claims are pretty much hooey.
Edit: What is this thread really about?
There is a lot of evidence of the harmful effects of artificial sweeteners. Here are some articles.
Of course those people who get their information from Coca Cola ads are not going to learn about the adverse vs beneficial health effects of artificially sweetened soft drinks any more than looking at a stripper in front of a soda machine will tell one if the technology behind Dash is sound or not.
What is this thread about? It is really about the relative value of facts based upon scientific evidence vs marketing baloney. This applies equally to beverages as to crypto currencies
Edit: Soft drinks was the most likely cause of Gulf War Syndrome among US veterans http://dorway.com/military-admits-gulf-war-illness-aspartame/ Aspartame breaks down in heat into toxic chemicals and the soft drinks were stored exposed to the hot desert sun in Saudi Arabia.
