Are you sure you trust the research in question? Without reading the literature at all, it seems to me like there may be a lot of confounding factors (e.g. maybe richer people drink more coffee). I’m especially sceptical because you list a large range of dubiously related diseases (so, richness would affect them all, but caffeine/whatever affecting them all is less expected). Beyond that, you also need to check the magnitude of effects—if it’s a minuscule change, it may well not be worth bothering with (and is even more likely to be because of noise).
So, yeah, very sceptical that these effects are real and worth acting on, although I suppose they could be. In theory.
