two weeks ago someting wierd happened. My husband(the diabetic) came in from outside and was cold. He drank a cup of black coffee to warm up and knowing that coffee has 0 calories he then took his blood sugar. Through the roof!!!!!!! couldn't figure it out, took it again, same result, took mine (non-diabetic) perfectly normal. mulled it around for a while and went on line and googled blood sugar+caffiene. There have been recent studies indicating caffiene can increase insulin resistance by up to 257%. Switched to decaf and his readings have been in the optimal range ever since. Go figure! thought that this was important enough to share.

Thanks, and welcome to our forum.

I never drink more than one cup of coffee per day. I use one slightly heaped teaspoon of instant coffee in a cup, and the same amount of Cremora. that is 3 carbs and I bouls 0.5 units of insulin. It has never affected my BG levels. Sometimes I drink hot tea, and it is carb free, so I do not need insulin for that.

Hello and welcome to the forum! I don't drink that much caffeine, so I never really noticed any increase from it. I get way to hyper when I injest caffeine. I hope you can join us often!

Brrrr…. Now that is what I call Bad news, I am a total coffee addict and just love tasting the different makes and even have some of my own blend made up.
My normal consumption is between 5 to 10 cups a day
This is going to be another tuff habit to break.
