Type 1 here, but I thought the following was interesting.
I read a similar article a couple of years ago about a different study that used Canadian lab rodents of some sort with the smae result. My type 2 diabetic coworker told me he notices if he has pasta for dinner, his bg is high the next morning, unless he has a glass of red wine with it.
I don't drink wine because I'm allergic to it- unfortunately. My fam are huge wine drinkers...
I used to smoke but quit because I couldn't rationalize continuing to smoke with diabetes. But, I miss it terribly, and I could sure go for a nice tasty cigarette right now... :)
To me, drinking a moderate amount of wine and smoking are too entirely different things! Smoking is proven to be extremely hazardous for your health, though I don't know that it has any immediate effect on blood sugar. Wine in moderation is neither hazardous to your health or to your blood sugar. I really enjoy a glass of wine with dinner and it's been many years since I drank to get drunk. I'm a child of the 60s - been there, done that and then some! I feel grateful to be here and though I have things wrong with me - type 1 diabetes, thyroid and arrhythmia, I don't know that I can attribute any of that to my dissolute youth..lol. I also enjoy dark beers but have had to curtail that because they do affect blood sugar, one beer only and if I'm eating something with few carbs.
I'm LADA/Type 1, on MDIs and about to start pumping.
I know a couple of type1 smokers here. lots of red wine drinkers. I think Liz's advice is good, tackle one thing at a time. You might meet some smokers here
also, George Simmons here successfully quit smoking recently. He's known on Twitter as @ninjabetic. he was the guy playing basketball with his son on the World Diabetes Day video here.
Smoker! Went from a pack a day to half pack a day the day I was diagnosed. Now I'm down to five a day (cigs, not packs) but kind of hit a rut with it. Tried the patch but just wound up smoking on it. Docs want to wait a month before I get chantix.
No wine (get terrible headaches).
