Confusion between NCCDB VS USDA
I am really having a hard time on knowing which one to use, the NCCDB vs USDA. Usually on common stuff say as carrots, their numbers are way different. Is this just preference based? I see the NCCDB is alot more detailed, but if the numbers between the 2 are vastly different, then I do not know which one to use correctly. I typically but all my produce unlabeled. I tried to look up on the grocery store website to see if they gave nutrition info but they do not.
