Rick,
I apologise if I upset you - I didn't mean to lambast you. I was just concerned that readers would think that eating 300g carbs per day (100g per meal) is what they should be aiming at. The point is (particularly for a type 2 - which 85% of diabetics are) that a very low level of carbohydrate won't do you any physical damage, whereas a very high level certainly will do enormous damage. Like you, I am surprised that Fergus can manage on a 30g intake, but 300g is about double what DUK and the ADA recommend for a diabetic - and most recent independent studies have been saying that even the ADA recommended 160g is way too high.
As Fergus has mentioned several times, and there are many studies to back this argument, the diets recommended by authorities in the western world (the balanced meal plate in UK and the food triangle in US) since the 1980s are now believed to be the major cause of the explosion in both diabetes and obesity. The proportions of 50% carb, 35% fat and 15% protein are way out of date. The new US guidelines published in 2005 recommend a daily intake of 6 oz carbs and 5½ oz proteins, with lower quantities of fruit. veg and fats.
I can only suggest that you (and Erroneous) have a look a Dr Richard Bernstein's book "The Diabetes Solution". You may or may not agree with what he says, but please read it before you make a judgement. And incidentally before anyone dismisses him as a quack - he is recognised as one of the world's leading endocrinologists.
