Sorry but they do not "get" the importance of low carb if they are eating 76% carb foods...and they have obviously not been told to check the back of the pack.
my brother understood the importance of lowering his carbs. Problem was, he was then looking for, and eating, no added sugar products, thinking that meant low carbs too. The misleading and deliberate weasel words on packaging is a minefield, especially for those who are dyslexic or have other reading issues, like my brother.
even on the back of packets over here, you have to double check the portion size the figures they give relate to, and its easy to make a mistake.
and then there is the bit about being told fructose not counted as its a fruit sugar and good for you..................
I had to eventually take a morning to go round the supermarket and teach him how to read and unscramble the conflicting and misleading package words and tables into some sort of understandable form.
and he is a guy who was eager to low carb and thought he had got it right : (
Its a minefield.
