I have checked my facts and the book and it is a conundrum...
Using the CP Values from the DAFNE Carbohydrate Portion List book
Weight of raw potato is X grammes.
Carbohydrates = X/100 x 1.5 CP
Weight of same potato baked in oven to produce Jacket potato is X-150 g
Carbohydrates – (X-150)/220 x 7CP
____________________________________________________________
Applying my weights as an example, if the raw potato weighs 370g
Carbs raw = 370/100 x 1.5 = 5.5CP
Weight of same potato after baking is 220g
So carbs for baked (jacket) potato is 220/220 x 7 = 7CP
i.e. The potato after being baked contains 1.5 MORE CPs than when raw.
WHERE HAVE THESE EXTRA CARBS COME FROM?
