【medical-news】糖尿病患者少喝咖啡有助控制血糖
Monday, January 28, 2008
Cutting down on caffeine could help people with type 2 diabetes control their blood sugar levels, according to a new study by scientists at Duke University Medical Center.
The researchers studied a small group of people with established type 2 diabetes who drank at least two cups of coffee everyday and who were trying to manage their disease through diet, exercise and oral medications, but no insulin. Scientists used new technology — a tiny glucose monitor embedded under their abdominal skin — to continuously monitor sugar levels over a 72-hour period.
Participants took capsules containing caffeine equal to about four cups of coffee on one day and then identical capsules that contained a placebo on another day.
The researchers found that when the participants consumed caffeine, their average daily sugar levels went up eight percent. Caffeine also exaggerated the rise in glucose after meals — increasing by nine percent after breakfast, 15 percent after lunch and 26 per cent after dinner.
"We’re not sure what it is about caffeine that drives glucose levels up, but we have a couple of theories," said lead author of the study Dr. James Lane from Duke University Medical School in a news release.
"It could be that caffeine interferes with the process that moves glucose from the blood and into muscle and other cells in the body where it is used for fuel. It may also be that caffeine triggers the release of adrenaline — the ‘fight or flight" hormone that we know can also boost sugar levels."
There are no current guidelines suggesting diabetics shouldn't’t drink coffee, but Lane said that day may soon come.
"Coffee is such a common drink in our society that we forget that it contains a very powerful drug — caffeine. Our study suggests that one way to lower blood sugar is to simply quit drinking coffee, or any other caffeinated beverages. It may not be easy, but it doesn't’t cost a dime, and there are no side effects," said Lane.
The findings appear in the February issue of Diabetes Care.

研究显示：减少咖啡因摄入有助控制血糖

Cutting down on caffeine could help people with type 2 diabetes control their blood sugar levels, according to a new study by scientists at Duke University Medical Center.
杜克大学医学中心的科研人员最近研究发现，减少咖啡因的摄入有助于2型糖尿病患者血糖水平的控制。
The researchers studied a small group of people with established type 2 diabetes who drank at least two cups of coffee everyday and who were trying to manage their disease through diet, exercise and oral medications, but no insulin. Scientists used new technology — a tiny glucose monitor embedded under their abdominal skin — to continuously monitor sugar levels over a 72-hour period.
研究人员对一组每天至少喝两杯咖啡的已确诊的2型糖尿病患者进行了研究。这些患者均未使用胰岛素，每日通过饮食、运动及口服药物来控制病情。科学家采用了一项新技术——在患者腹部皮下植入一个小型监测器——持续监测患者72小时的血糖水平。
Participants took capsules containing caffeine equal to about four cups of coffee on one day and then identical capsules that contained a placebo on another day.
受试者第一天服用咖啡因含量相当于四杯咖啡的咖啡因胶囊，然后第二天服用外观相同的含安慰剂的胶囊。
The researchers found that when the participants consumed caffeine, their average daily sugar levels went up eight percent. Caffeine also exaggerated the rise in glucose after meals — increasing by nine percent after breakfast, 15 percent after lunch and 26 per cent after dinner.
研究人员发现，摄入咖啡因的患者平均每天血糖水平上升8%。咖啡因还促使餐后血糖升高——早餐后增加9%，中餐和晚餐后分别增加15%和26%。
"We’re not sure what it is about caffeine that drives glucose levels up, but we have a couple of theories," said lead author of the study Dr. James Lane from Duke University Medical School in a news release.
"我们还不能确定究竟是什么原因导致咖啡因升高血糖，但我们有一些理论可以解释该现象"，这项研究的第一作者杜克大学医学院 James Lane博士在新闻发布会上说。
"It could be that caffeine interferes with the process that moves glucose from the blood and into muscle and other cells in the body where it is used for fuel. It may also be that caffeine triggers the release of adrenaline — the ‘fight or flight" hormone that we know can also boost sugar levels."
"咖啡因可能干扰了葡萄糖从血液进入肌肉和体内其他细胞提供能量的过程，也可能是，咖啡因触发了体内肾上腺素的释放-——“战斗或逃避反应”激素，我们知道肾上腺素也可以升高血糖。 "
