Does coffee raise blood sugar?
 

I always drink my coffee with cream (lower carbs) and splenda. However, my BG always rises a solid 25 - 50 mg/dl after I drink my morning joe. Anyone else?

I have cream and splenda...and yes it does raise my BG levels some and can be easily managed if planned. Also, beware of flavored creams...they have at least 5 grams sugar per serving. Black is best, but I treat my coffee as a snack and count it as so.

I will have to agree with the others on this. I think that coffee does not cause a rise in the blood glucose level. However, I am willing to bet that the other ingredients (creamer & splenda) are the culprits. I drink a couple of cups of coffee, in the morning, without any other ingredients and find no rise in the blood glucose level. Just my $0.02 worth, other opinions may vary.

To much coffee isn't good at all, even for a none diabetic.
My father always says: "If its not good for a "normal", its totally not good for a diabetic".

Rob was having a similar issue. For a while his sugar levels are unusually high even without eating and he couldn't figure out why. It wasn't until I was putting milk in my coffee and was casually reading the nutritional facts that I figured it out. He was drinking 2-3 large lattes a day. 1 cup of milk can have 12-16g of sugar. You figure between 1-2 cups of milk per latte and that totally explains the sugar levels. He now only uses a tiny bit of half and half.

He doesn't use sugar because he's alergic to the binding agent used is most artificial sweetners...Is that not crazy terrible luck? A diabetic who is also allergic to artifical sweetners.

Keep in mind some diabetics have issues with too much Caffeine. Also, depending on what you're using, even half and half can raise your glucose along with Splenda.

When i goto starbucks, i get one of the sugar free's decaf with soy. Soy has a little sugar, but nothing like what the syrups have. Never have glucose issues.

Sugar Free Coffe-mate
 

I switched to Coffee-mate non dairy creamer (powder at work liquid at home).
The powder has only 1g carbs per tablespoon and 0 sugar according to the label. I haven't noticed any spike in meter readings after having coffee with this.

One thing I don't do however is trust the sugar free non dairy creamer from the any convenience store. I'm sure the just throw the regular French Vanilla in when they run out of sugar free. Just looking at the little creamer thing makes my spidey sense tingle.

Coffee all day long
 

I drink coffee with 1/2 1/2 all day long at work and at home--over a liter in all--maybe about 100ml cream--and just consider it as part of the background noise re my BG. So, coffee is the norm and I have no intention on modifying my coffee intake. However, I am working toward the modification of my diet and amount of consumption. My wife brought home a poster which she posted on the refrigerator the following: THE NEW FOUR FOOD GROUPS: FRUITS, LEGUMES, WHOLE GRAINS, VEGETABLES. Although I feel that this was created by Vegans, I do feel that the closer I adhere to this diet the closer my BG stays in the "green zone" and the fewer spikes I hit. One word of advice on this poster is this: EAT BETTER: TASTE BUDS CHANGE. So true. In the meantime, I muddle through it, occasionally breaking the regimen-which my dietitian tells me as it is okay so long as it is the exception and not the rule. However, no one will be able to take me away from my coffee!

I was diagnosed with type 2 over 3 months ago. When I was first tested my blood sugar was at 798. I have changed my diet dramatically. Now I range from 97 to 123 ish. I told my wife that there are many things I will change, I quit smoking, I quit smoking marijuana(which I think is why my blood pressure is high now, no pun intended), I exercise now and I eat right, but my coffee nope not changing! I use International Delight Hazelnut and I do not use the low fat one. Unless she wants me super grumpy then I get my coffee the way I like it, I just make sure I have planned it in my diet that's all. I hope you are all doing well in managing your diabetes. Have a wonderful day :-)

Drinking coffee is a sure way to invite more problems. Drink clean water. Stay away from sea water. Clean water is best. Chlorinated pool water is ok, too.

Why coffee protects against diabetes
Researchers discover molecular mechanism behind drink's prophylactic effect
By Mark Wheeler January 12, 2011
Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.

Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee's protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body's sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG.

Reporting with colleagues in the current edition of the journal Diabetes, first author Atsushi Goto, a UCLA doctoral student in epidemiology, and Dr. Simin Liu, a professor of epidemiology and medicine with joint appointments at the UCLA School of Public Health and the David Geffen School of Medicine at UCLA, show that women who drink at least four cups of coffee a day are less than half as likely to develop diabetes as non-coffee drinkers.

When the findings were adjusted for levels of SHBG, the researchers said, that protective effect disappeared.

The American Diabetes Association estimates that nearly 24 million children and adults in the U.S. — nearly 8 percent of the population — have diabetes. Type 2 diabetes is the most common form of the disease and accounts for about 90 to 95 percent of these cases.

Early studies have consistently shown that an "inverse association" exists between coffee consumption and risk for type 2 diabetes, Liu said. That is, the greater the consumption of coffee, the lesser the risk of diabetes. It was thought that coffee may improve the body's tolerance to glucose by increasing metabolism or improving its tolerance to insulin.

"But exactly how is elusive," said Liu, "although we now know that this protein, SHBG, is critical as an early target for assessing the risk and prevention of the onset of diabetes."

Earlier work by Liu and his colleagues published in the New England Journal of Medicine had identified two mutations in the gene coding for SHBG and their effect on the risk of developing type 2 diabetes; one increases risk while the other decreases it, depending on the levels of SHBG in the blood.

A large body of clinical studies has implicated the important role of sex hormones in the development of type 2 diabetes, and it's known that SHBG not only regulates the sex hormones that are biologically active but may also bind to receptors in a variety of cells, directly mediating the signaling of sex hormones.

"That genetic evidence significantly advanced the field," said Goto, "because it indicated that SHBG may indeed play a causal role in affecting risk for type 2 diabetes."

"It seems that SHBG in the blood does reflect a genetic susceptibility to developing type 2 diabetes," Liu said. "But we now further show that this protein can be influenced by dietary factors such as coffee intake in affecting diabetes risk — the lower the levels of SHBG, the greater the risk beyond any known diabetes risk factors."

For the study, the researchers identified 359 new diabetes cases matched by age and race with 359 apparently healthy controls selected from among nearly 40,000 women enrolled in the Women's Health Study, a large-scale cardiovascular trial originally designed to evaluate the benefits and risks of low-dose aspirin and vitamin E in the primary prevention of cardiovascular disease and cancer.

They found that women who drank four cups of caffeinated coffee each day had significantly higher levels of SHBG than did non-drinkers and were 56 percent less likely to develop diabetes than were non-drinkers. And those who also carried the protective copy of the SHBG gene appeared to benefit the most from coffee consumption.

When the investigators controlled for blood SHBG levels, the decrease in risk associated with coffee consumption was not significant. This suggests that it is SHBG that mediates the decrease in risk of developing type 2 diabetes, Liu said.

And there's bad news for decaf lovers. "Consumption of decaffeinated coffee was not significantly associated with SHBG levels, nor diabetes risk," Goto said. "So you probably have to go for the octane!"

Other authors of the study included Brian Chen, of UCLA, and Julie Buring, JoAnn Manson and Yiqing Song, of Brigham and Women's Hospital and Harvard Medical School. Funding was provided by the National Institutes of Health. No conflicts of interest were reported by the authors.

My endo told me that there are studies right now looking at caffine raising BG. I have one to two cups in the morning and yes it does raise my BG. I usually work out right after so I dont worry about the little spike. It drops to normal after.

Hi all.. It's definitely the sugar substitute. In Dr. Bernstein's book low carb diabetic diet. He suggest to use the pellets instead of the packs because they do contain some type of sugar which of course will raise BG.. Use Stevia instead.. He also suggest the cream over anything else.. Try it see if it helps.

Coffee has no carbs and therefore does not raise or lower blood glucose. If you add sugar to it, then the carbs in the sugar will raise it.

study finds coffee beneficial (black coffee)
 

Black coffee is best, and very good to control blood glucose!

here is a blog that came out of the UCLA study:

Yep

Coffee for me does not raise my BG unless I add sugar... I only add cream and it actually helps to lower my BG.
