You can find the complete list of zero bite foods here in our Help Center.
When searching in the app you can find the Pocket Guide results which include zero bite foods under the heading Pocket Guide. Search results from the Pocket Guide also have a green checkmark after the name so you know all nutrition information & bite values have been verified for your plan. Please keep in mind no matter what plan you're on, the Pocket Guide is the definitive source for exact bite values.
All other databases including the barcode scanner, online database, restaurant guide, etc. all use nutritional information to calculate accurate estimated bite values for your specific plan. Similar to the BITES Smart plan you can tap the "0 Bite Food?" toggle to zero out any zero bite foods when tracking them through one of those databases.
