Really? Thanks for your help, but sadly I am confused ...
1) In my Collins Carb Counter reference book, it is emphasised to deduct fibre from carbs to get net carbs ... all foods are listed accordingly, to enable you to do this. I have been doing this forever ...
2) Food labels list Carbohydrates and also Fibre, so it never occurred to me not to deduct fibre from carbs ... why would they list fibre separately if it is already deducted? Where is the logic?
3) In many websites and books, in my general reading, it is mentioned that carbohydrates' impact is ameliorated by the amount of fibre the food contains, and many advise deducting the fibre content from the carbohydrate to calculate the impact. I thought this was just general knowledge. Sometimes it makes a big difference.
Coo, food is a nightmare, innit? Thank God I found this website ... it has corrected more that one misconception on my part.
(but I'm still baffled)
PS I was trying to be helpful ... Is it true, then? No Good Deed Ever Goes Unpunished ... LOL.
