Seconded. I would have issues that kept getting worse as I got older. I noticed that whenever I did keto, I felt much better. When I combined it with going gluten free, I felt amazing. Well, dad gets diagnosed with Celiac and my old DNA test results mentioned I was a carrier and more likely to develop it. I haven’t had the endoscopy yet, but it’s pretty likely. This sucks as I love bread and baking it.
Anyway, if gluten is an issue, rice flour can be used for a lot of things and corn/potato starch is a good thickener (whichever is cheaper where you are).
Ah. That’d be a nightmare here, probably. Japan is pretty notorious for low tech literacy outside of a few narrow areas. I also think that this might have reliability impacts that just drive people away. Finally, no average japanese person has any idea what the fediverse is, so that’s another hurdle to jump.
