Join a different instance, there are ones that are more curated for different regions in the world. Lemmy.world is very US centric and essentially a carbon cut-out of reddit. Lots of redditors migrate there and try to maintain that type of culture on the instance, so they also got many of the most toxic complainers condensed from mass reddit exoduses.
The fediverse is meant to be explored and it may take you a month or two to find where you like best.
Like I said, it’s not the healthy choice, but I’m also not going to demonize a person for having the occasional sweet drink.
A much better hill to die on is the systemic use of known carcinogens in products that we come in contact with everyday as well as the dumping of even worse materials into the environment that make their way into our bodies via the water we drink and the air we breathe. You don’t get to choose whether you are exposed to these things.
I think the consensus on health effects of artificial sweeteners is unclear so long as you only consume a reasonable amount. There are plenty of other synthetics in highly processed foods that are much more concerning.
That said, water is obviously healthier.
At least one company made a soylent, it’s just not soylent green. Not sure if it contains soy or lentils.
Or join an instance they don’t like and they curate themselves for you. :)
