Fair enough, but not that it still may be impossible to discover an efficacious recommendation to the general public, if it so happens that the general public consists of subgroups of people with considerably different kinds of nutritional biochemistry. My general impression from a number or recent research reports is that suggestive evidence is accumulating that this in fact is the case, e.g. the distinction between those with insulin resistance and those without. >> For diabetics, pre-diabetics, etc. there is a simple answer to this >> problem: get a BG meter and avoid the foods which spike your BG. > From a cardiovascular perspective, BG spikes are not as bad as prolonged > periods of modest BG elevations (i.e. fasting BG of 150-200 mg/dL with > max of 250 mg/dL is less optimal than fasting BG of 100-150 mg/dL with > max of 250 mg/dl in the form of transient post-prandial "spikes") You're quite right, but there is also accumulating suggestive evidence that if you want to stop the progression of diabetic complications it may be necessary not only to bring down prolonged modest BG elevations, but also transient high prost-prandial BG spikes. In other words, while BG spikes are not as bad as modest prolonged elevations, they're still bad enough to damage you, although more slowly than prolonged modest elevations. >> Wait a minute!

I do hope so. There are certainly a lot who do. But you can't read this newsgroup without noticing that there is certainly a significant number of doctors who react with dismay to the idea that patients should be given some responsibility for dosage adjustment, etc.. In my own UK NHS experience, whenever I've changed medical group practice I've selected a new practice with a particularly good reputation, but I've nevertheless had to work my way through a few doctors before I found one that wasn't upset by how much I wanted to know, how much I did know, and how much I wanted to take my own decisions based on them helping me to become as fully informed as I thought necessary. I'm not talking about a mild reluctance. I'm talking about doctors who far example would refuse to tell me what my blood pressure was, and would simply go on insisting that all I needed to know was that it was "ok for my age". > That is certainly how the > diabetic 2PD-OMER Approach is structured: > http://www.HeartMDPhD.com/wtloss.asp Yes, I would agree, and as I've posted in the past, I've discovered by expriment that with my typical kind of diet, 2lbs is about the threshold for me above which I gain weight and below which I lose it. I'm sure, however, that you can recall a number of doctors disagreeing with your diet on the grounds that a member of the public couldn't be trusted not to eat 2lbs of ice cream and think they were following your diet. -- Chris Malcolm +44 (0)131 651 3445 DoD #205 IPAB, Informatics, JCMB, King's Buildings, Edinburgh, EH9 3JZ, UK [http://www.dai.ed.ac.uk/homes/cam/] |

Those would be the doctors that covet the LORD's power :-) Would be more than happy to "glow" and chat about this and other things like cardiology, diabetes and nutrition that interest those following this thread here during the next on-line chat (12/22/05) from 6 to 7 pm EST: http://tinyurl.com/cpayh For those who are put off by the signature, my advance apologies for how the LORD has reshaped me: http://tinyurl.com/bgfqt Many Christmas blessings, Andrew http://tinyurl.com/b6xwk |
