The point of verified food is that it's supposed to be accurate, and as part of that you can't edit it. That's all well and good. But, a few times now I've found "verified" food that isn't correct - I'm looking right at the label and it's not the same numbers as the site. Most likely this is due to manufacturers changing their recipe which in turn would change the nutrition facts. Right now, my only option when that happens (unless I'm missing something) is to find an unverified entry that is correct or that I can later edit and correct.
I always double check the nutritional information when I have the label, but that doesn't always happen. In those cases I have to pick from a number of entries for the same item with no clue which one is actually correct. Now, verified food is supposed to be one I can just pick and trust. But how can I trust it when it very well could be wrong too?
My suggestion is to be able to flag a verified entry as incorrect and then have someone review its verified status.
(I typically add food using the android app for the barcode scanner)
