It is my understanding that where it comes to carbs, the fibre and sugar content does NOT exceed the total carbs. Is this correct?
The reason I ask is that I was just checking out a food item (Feijoas) on the USDA site ndb.nal.usda.gov/ndb/foods/show/2411
and it shows "Carbohydrate, by difference" to be significantly lower than the fibre and sugar content combined. Is the "Carbohydrate, by difference" different to JUST carbs?
