What's a good way to track shifting snack preferences among Gen Z?

Surveys alone definitely won't cut it here — Gen Z's snack choices are heavily influence-driven, so I'd layer in social listening tools like Brandwatch or Sprout Social to track what's actually trending on TikTok and Instagram in real time. Pair that with ethnographic-style food diaries (even just a 5-7 day mobile diary via platforms like dscout) to catch the spontaneous, unplanned snacking moments surveys miss. That combo usually surfaces way more honest behavior than self-reported data.
