Caffeine article by a trendy dietician and it's affect on bgs.

For what its worth, I used to drink 4 or 5 cups of Americano (double shot of esspresso & hot water) and also a few cups of tea every day, some time ago I accured a taste for green tea and only drink 1 or 2 cups of that every morning now and a similar amount of fruit infusions throughout the rest of the day and can categorically state that I have noticed absolutely no difference in my bg levels since stopping most of my daily caffeine intake.
 
I find that my first coffee of the day has a heightened effect on bg and DP. did wonder if that was caffine related
 
I wonder how the trendiness or otherwise affects the data? It seems to have been a systematic review of a lot of other high-quality trials, combining all the data together - this helps rule out individual trials' issues and provides a bigger number so there's less chance the result was random.

Systematic reviews are usually far better at determining the evidence than individual trials. While the result can be said to be true at a general level, there are so many different types of diabetic - I'd like to see how the data splits by different segments of patients, but for me, I think it's worth a go. I'm not sure I could give up coffee, but will certainly try de-caff for a couple of weeks.

(I do worry though, that I might never have another bowel movement without caffeine)
 
My day lasts longer after drinking diet coke. My thyroid seems to be worked more. I have no effect on my bgs. Full caffeine or decaf.
Everyone is different.
Thanks @ChrisSamsDad but I totally agree it looked like trials held with full cross sections. I called her trendy due to her being the first to blog dietary advice.
I posted as I know my experience is not the full article and once again note I have no bg affect. Mind you I am taking 2 meds to keep blood pressure down. That might be how bgs test higher?
 
Seems like quite a good review. As the authors point out, further research is needed to determine whether similar effects occur when caffeine is consumed as a normal part of the diet spread over the day rather than as a supplement/in a single dose. A can of coke has only 40 mg of caffeine compared to 200-500 mg in the trials quoted so any effect on blood glucose might be too small to detect with a home meter. For Type 2 coffee-drinkers, it might be worth trialling decaff for a bit. Alternatively, as caffeine only affected blood glucose after a glucose load, any hyperglycaemic effects could be avoided by not eating until 3 hours after a coffee.
 
I guess anything in moderation is safe. Caffeine included.
Increasing bgs obviously works for some but I must be one of the lucky ones as my bgs don't increase when I drink a regular coffee nor diet coke.
I do call myself an caffeine aware person and I don't drink caffeine everyday and when I do it's 2-3 drinks maximum.
In fact I drank diet coke through both of my pregnancies without any shaking babies from withdrawal. I was very careful how much caffeine I drank.
 
I hope you are all drinking black coffee or at least with no mik or creamer. Bulletproof coffee is probably sufficient low carb not to affect bgl, but milk certainly does. In terms of caffeine being the cause, then a swift overdose of ProPlus would quickly determine if caffeine was affecting bgl. We used to use these tabs to keep us awake when on sentry duty in the army. but they had a sting in the tail when they wore off. The other consideration is that caffeine is a mild diuretic, so will lead to dehydration if drunk in excess (i.e. expresso's galore) It also raises BP levels by the action of epinephrine.
Edit to add: Caffeine when drunk as coffee or tea does not dehydrate due to the added liquid. there is debate about Green Tea though. Caffeine in tablet form such as ProPlus can have an effect if overdosed.

How you cope with caffeine is highly individual and based on your genetics:

"Coffee has a greater effect on people who metabolize caffeine more slowly. The reason for this is that our genetic makeup, which determines the activity of the enzyme CYP1A2, is important for the metabolism of caffeine. The aforementioned enzyme doesn’t work adequately in some people, so the daily dose of coffee has to be adapted to this deficiency."
 
I agree that the substance caffeine is a mild diuretic. However, if it is consumed in the form of coffee/tea/cola, the amount of water consumed in the drink far outweighs any diuretic effect of the caffeine and therefore normal caffeine-containing drinks do not have a diuretic effect.
 
Actually I found that Starbucks coffee had a violent purgative effect. Never again.
I agree with your comment, and will edit my post accordingly.
