Your thoughts?

According to the Mayo Clinic, caffeine can impair insulin reaction. This means it may take more time for your dose of insulin to fully kick in. Caffeine can also increase your body’s resistance to insulin.

In addition, a 2008 Duke University study showed that caffeine may have an impact on your blood glucose levels. The study examined people with type 2 diabetes. One group of participants took 500 mg caffeine–about the equivalent of two cups of coffee–every day for a week, while the second group abstained from caffeine. Each person’s blood glucose levels were tested multiple times throughout the week, and it was found that those who drank caffeine had blood sugars around 8 percent higher than those who didn’t take caffeine.

My first thought was I couldn't care less because I'm not giving up my coffee! Seriously though, there are so many things that have a more significant impact on glucose levels that most people on this site have already given up, that the smaller impacts such as coffee will just have to be tolerated and that's that. I note the article suggests a 'low fat smoothie' in its place so I'm betting that doing that will have an even worse effect.
 
Hi,

I know caffeine is a stimulant. I always thought it was more likely if anything to evoke a liver dump with the rush..?

I love coffee too.

Not sure whether to laugh or cry. Though to be fair, it does say to check the sugar content. Maybe we should be vampires and drink blood?
As a T1, I guessed that coffee doesn't help my dawn phenomena, but I'm afraid I just inject for it.
 
You have to wonder why they did a coffee test without using coffee.

"Let's test how coffee affects blood glucose"
"Great idea! How much coffee will the test subjects drink?"
"None! We'll give them pills instead"

Coffee also tends to promote snacking in a subconscious effort to get rid of the sometimes bitter aftertaste. This alone could account for a significant glucose swing in many people.
 
This morning before coffee 4.9 after coffee 5.4 not a lot of difference I am a regular coffee drinker never seems to effect my blood sugars to any great extent so I will continue drinking coffee for now.

Must add till I've had my coffee in the morning I'm a right grumpy so and so
 
My main thought when reading this is the frequency of the words "can" and "may".
To me this just emphasises the importance of testing what impact it has on your blood sugars before making any decision whether to drop something you enjoy or not.

The other thought is this is focused on coffee but the test is with caffeine so what about coke and other caffeinated drinks?

It's not going to make any difference to me - unfortunately, coffee is one of the very few things I can't stomach. Nothing to do with diabetes or blood sugars, the smell just makes me feel so nauseous that I can't drink it.

I have 2 cups in entire day and i have never noticed any such relationship. i have coffee as mid morning and evening snack alongwith some nuts.

I've never been a coffee drinker but I do drink tea, and I wonder if this makes any differences? Maybe they will try that next! lol
 
I am a true coffee lover and I drink it heavy which i am trying to avoid due to my soaring LDLs. Coffee also raises my BP significantly (tried and tested). Without coffee my BP is below 120/80, after coffee it can cross 130...

Agreed @EllieM, we may become vampires in the end ....

I've never really thought or heard of that concept, I suppose it could be a factor in the way that tea can often be accompanied by biccies.

Cry I reckon EllieM. I can't get my head around what a low fat/low sugar smoothie would consist of???, I'm imagining offal & steak!
 

Hi Finsit, what is the breakdown of your cholesterol levels? My total levels are 7.5 (HDL 2.45, trigs 0.5, LDL around 5), and as far as I know have been in that range for ever, long before diabetes popped up. I was referred to a Lipidologist and after various DNA tests, they decided I had polygenic Hypercholesterolaemia...meaning it mattered not whether I had cream in my coffee et al, in fact they actually said nobody should be worrying about cholesterol from the food they eat as it's mainly produced by the body to the extent that what you cut out in food is replaced by the body anyway. I find it interesting how they've decided to label me with a 'condition' I didn't know I had and has never affected me in any way so far based on some other person's 'average'.
 

I don't think i have familial or poly hypercholesterolemia because my readings were not that high before i started low-carb. Even though my HDL and TGs improved, LDL skyrocketed. Please see my readings for the last three years. March 19, 2019, i was on low-fat diet and didn't know i am diabetic. I have this genetic condition G6PD deficiency and i doubt that is playing a role in my fat metabolism. Not that i am much worried about my LDL, i still don't like numbers as high as they are now only after i switched to dairy cream and dairy fats mainly where i seem to be hypersensitive.
