At least here in Finland, officials recommend a snack between breakfast and lunch, and between lunch and dinner. We also have an “evening-snack” which is like breakfast but eaten an hour or two before going to sleep. Some officials, mostly dental-related, do think snacking is bad for your teeth or something, but we Finns do use xylitol quite often so I don’t think that consern is too important. When it comes to snack, its often fruit, maybe coffee and a bun. But definitely not chips or candy bars
