like, it’s caffeine and water and brown, who cares. i drink diet soda so it’s no calories, no sugar. versus the stereotype starbucks order, why is soda so demonized
the whole sort of basically woo stuff about oh there’s antioxidants there which give you a 3% lower risk of skin cancer after the age of 65 like come on that doesn’t count
It’s not the same drink, your premise is flawed. Coffee has way more caffeine, is generally served hot, and most importantly, tastes completely different.
Diet soda is also still not good for you.

Basically, black coffee tastes better (subjective), has more caffeine, and is less bad for your health. Alternatively you could go the tea route but personally I prefer coffee.
The quote that you’ve included doesn’t say that diet soda is bad for you, only that it’s “not clear if it’s effective at preventing obesity”.
