How do I edit or delete a logged food?
To edit a logged food, tap it in your Food Log. From there you can change the amount, serving size, meal, date, and time. On Mac, click the entry instead.
To delete an entry, open it and tap the trash button in the toolbar. You can also touch and hold an entry in your Food Log and select Delete. On Mac, Control-click the entry and select Delete.
Editing or deleting an entry only affects your log for that day. It doesn't change the food itself, so other entries that use the same food stay as they are.
Entries imported from Apple Health can't be deleted in Foodnoms. Delete them in the app that created them or in the Health app on your iPhone.
