Vitamin A in carrots
 
So, just out of curiosity, when I look at the nutrition information for carrots, it says 3 oz. is 242% of my Vitamin A, but when I log it, and go look at my nutrition info for the day, it doesn't add up to anywhere near that. Is this a deliberate thing, like coded into the algorithm for how vitamin percentages are calculated based on like, how your body absorbs it or something? Or is it just a bug? I don't know if these things simply are supposed to add linearly or not.

Great question. I believe this explanation for Supplements explains this nicely:

Ah - very nifty! Thanks Vito, I figured someone had probably asked long before me, I appreciate you digging up the thread.

You're welcome, Joanna. Actually, it was "kinda" asked before, but not exactly the same way as you asked it.

I really like the answer as it explains just how "robust" the FD program is. It's just a shame that people don't know what they're talking about when they jump to the conclusion that there's an "error". No error, customization! :)

You were wise to not jump to any conclusions about an apparent discrepancy. :)
