I’m always tempted to get one but can’t quite justify the purchase. What difference does it make to your quality of life?

I used to feel the same about settings pages but I’ve noticed I’m so used to the auto save settings way I now get annoyed at the opposite - when I change some settings, exit the page and then discover I’ve lost the changes because I was meant to click save.

I guess either way can work fine it just needs to be properly designed.

I’d suggest not calling anything out. People may well not hear exactly what you said and, even if they do, are unlikely to be able to process the information quickly enough. They’ll end up guessing what to do and that will often result in them doing the ‘wrong’ thing.

Could you provide a explanation for someone not in the US?

Yeah and you can systematically work through the various FODMAPs to figure out which ones cause you problems. It’s not that FODMAPs are all bad, it’s that there are groups of foods that you might be sensitive to.
