Firstly, I think Catherine was looking at a different forum, or possibly one of the newsgroups. Certainly to my knowledge no-one has posted anything rude to Catherine from any source, people simply expressed their doubts and reserves about recommending such a high carb diet to diabetics.
Not all were negative, people pointed things out and suggested substitutes. Catherine came back with some extremely patronising responses which got people's backs up in various places around. To my knowledge the one or two threads in other places that I have seen were expressing people's annoyance at her attitude which was frankly scathing of their knowledge of what would be a good diet for diabetics. One thread was jokey and I myself wrote up a "spoof" response to her which was meant to be funny and was, to my knowledge, never sent to her. I have not seen, anywhere, anything worse than was posted in the 2nd carb thread on here. So where she is getting the "personal attacks" from I do not know.
From the example day on this link which is the suggested diabetic diet
http://www.tescodiets.com/index.cfm?currpage=dietplans&subsection=dietintro&dietchoice=9&code=350144 I work out the carb count thus:-
Breakfast
60g Weetabix minis = 41g carb
Milk = 9g
Probiotic drink = 9g
Medium Banana = 35g
total = 94g
Lunch
Pitta = 25g
Cottage cheese = 9g
Medium apple = 15g
total = 49g
Snack
half muffin = 15g
Dinner
*Risotto = 39g
Grand total = 197g
*I have a risotto recipe which states 50g Arborio rice per person.
Of course my maths is rubbish, but I did bother to weigh an apple and a banana and deduct an amount off the banana for the skin. The other carb amounts came from the Collins Little Gem Calorie book and/or the internet.
IMHO that's rather a lot of carbs per day for a diabetic. It's indeed reminiscent of the "food pyramid" suggestions that we all know are far too starchy. Since the rest of the world are realising that the starchy carbs with every meal advice is wrong, surely we, as diabetics, should be banding together to get the British recommendations overturned.
