This may be different in the US, where, from my understand, people often eat sweetened breads and so on, but at least here in Europe, added sugars are really not that hard to avoid. (Well, at least to a 99% level. For me, cutting soy sauce, which does contain added sugar, would be very uncomfortable. Other than that, I honestly don't see the huge issue - of course it would be annoying when eating out, but that's about it.)
