Well said Sunflower. Good summary.
There is another fly in the ointment as well of course. Two of the most recent studies into BG testing including the Farmer one almost seem to have been set up in order to justify restricting test strips.
They missed the fairly basic principle that the results of testing need to be used. The conclusions they reached were that testing for T2s is pointless. Its not until you read into them further that you realise the conclusions should have been Testing for T2s FOR NO REASON is pointless. In both studies, the patients were forbidden from changing diet and lifestyle relying only on changes to prescribed meds.
Which raises the question of why they were testing in the first place.
If the results of testing are used to change diet and exercise regimes then this is very effective in DM management.
However, these studies demonstrated that if you give people the standard diet sheet and use BG testing to encourage adherence to this diet, then people have no significant improvement in A1c, see that there's no improvement and get depressed.
In responses to these studies on the BMJ site, one posted nominated the depression-related study for a "no .... sherlock" award.
Actually these studies give more of an indication that the standard dietary approach does nothing to help BG control. Could that possibly be true? Well lets see.....we've all heard it....
"Sorry, you have diabetes. BG gets raised by carbohydrates. Now go away and eat 30-50% starchy carbs with every meal"
er.....what? 😉
