Unfortunately, little iron in food packed with carbs (10)
I believe the answer is:
tortellini
'food packed with carbs' is the definition.
I can't judge whether this defines the answer.
'unfortunately little iron' is the wordplay.
'unfortunately' indicates anagramming the letters (a bad or unfortunate spelling).
'little'+'iron'='littleiron'
'littleiron' with letters rearranged gives 'TORTELLINI'.
'in' is the link.
Can you help me to learn more?
(Other definitions for tortellini that I've seen before include "Italian dish" , "Rings for food" , "Small filled pasta cases" , "pasta dish" , "Pasta is called for" .)
