Type 2 Diabetics Should Avoid Caffeine

HealthDay Reporter
MONDAY, July 26 (HealthDayNews) — Consuming beverages that contain caffeine
may not be a good idea if you have type 2 diabetes, researchers report.
In a small study, Duke University scientists found a link between caffeine
at mealtime and increased glucose and insulin levels in people with type 2
diabetes. The finding suggests diabetics should reduce or eliminate caffeine
in their diets, according to the report in the August issue of Diabetes
Care.
"Caffeine seems to impair the metabolism of carbohydrates in patients who
have type 2 diabetes," said lead author James D. Lane, an associate research
professor of medical psychology at Duke University Medical Center. "So it
seems to make diabetes worse."
Levels of glucose — blood sugar — are elevated in people with diabetes
after a meal because the body isn’t able to metabolize the glucose, Lane
said.
"If your blood glucose goes higher after every meal, then your average blood
glucose level is going to be higher, and that could aggravate diabetes or
increase the risk of complications," he said.
Diabetes is a disease in which the body doesn’t produce or properly use
insulin, a hormone needed to convert glucose into energy for the body.
In their study, Lane and his team recruited 14 regular coffee drinkers who
had had type 2 diabetes for at least a six months. These subjects took
medications for their diabetes, but did not require insulin.
The researchers looked at how much caffeine the people consumed over a week.
The subjects were also given two 125-milligram caffeine capsules or a dummy
drug, which were taken with a commercial liquid meal (BoostR) that has 75
grams of carbohydrates.
Lane’s team measured the patient’s blood glucose levels before and after
eating and taking the caffeine pills.
The researchers found caffeine did not affect glucose and insulin levels
after fasting. However, the study participants who drank the liquid and then
took a caffeine pill experienced a 21 percent increase in glucose and a 48
percent rise in insulin levels, compared to the other study subjects getting
the placebo.
Lane’s group also compared the effect of caffeine with the medications
diabetics take to lower glucose after a meal. "We found that the size of the
increase in glucose due to the caffeine is as large as the decrease that
occurs when people take medications to lower glucose," he said.
Based on the findings of this small study, Lane believes that "people who
have type 2 diabetes may be better off if they avoid caffeine."
Curiously, a study released earlier this year found that coffee can help to
prevent the onset of type 2 diabetes, reducing the risk by almost 50
percent. However, the protective effects didn’t become significant until
people drank at least four cups a day.
Tomas de Paulis, a research assistant professor from the Vanderbilt
Institute for Coffee Studies at Vanderbilt University, said, "It is well
known that caffeine has a detrimental effect on glucose tolerance."
"What is less known is that coffee also contains compounds with the opposite
effect. It is not coffee but the caffeine that should be avoided by diabetes
patients," he added.

The American Diabetes Association has plenty of information about the
disease.

"In their study, Lane and his team recruited 14 regular coffee drinkers "
… how many was the pro-coffee Harvard report based on? 100,000?
Not enough evidence to wean me off my favourite drug yet!

And then there’s the amount of carbs —
"The subjects were also given two 125-milligram caffeine capsules or a dummy
drug, which were taken with a commercial liquid meal (BoostR) that has 75
grams of carbohydrates."
I’m no low carber, but I don’t take in 75g at a time
(maybe at *major* pizza pigout, & only w/ meds — i.e. a large helping of
Prandin — but that’s not very often)

Yeah – EW! Bet their stress levels were shot to hell and gone, slopping down
that kind of junk. : )

Missed that – it tends to make the rest of the results meaningless with
that sort of BG load.

It sounds revolting to me. Now, if they’d do the test with a nice big
chocolate (maybe also malted) milk shake, I could handle it — at least the
drinking it down part — with a smile. My bg would be horrific, but at least
I’d have had a taste treat!

Blimey! Why aren’t they pushing what’s to me it’s most important effect,
that of beta cell regeneration?
