This was a well designed article that I found an interesting read. Here are my thoughts on how it applies to the latest research on coffee and type 2 diabetes:<br /><br />1) Caffeine has been shown to increase blood sugar in large doses in previous investigations. This is likely why we perceive a boost in energy after we drink a cup of coffee.<br /><br />2) The dose is highly relevant here. In the study you cited, the researchers gave subjects a dose of caffeine equivalent to 5 mg of caffeine per kilogram of body weight. I weigh 185 pounds (84.1 kilograms), so if I was in this study, I’d receive 421 mg of caffeine, which is the amount in 6 cups of coffee! This is a huge dose to be drinking at one time. There are many examples of substances that are beneficial in small doses but harmful in large doses. Alcohol comes to mind. A drink a day has proven health benefits, but 6 or more a day and you’ll wreck your health.<br /><br />3) There are both acute and chronic effects of substances on our bodies. A stimulus may look harmful in the short term, but be beneficial in the long term. For example, physical activity increases blood pressure and heart rate acutely, but lowers them chronically. Coffee may very well do the same thing with our blood sugar.<br /><br />4) Other substances in coffee may work to counteract the negative effects of caffeine on blood sugar. There are literally hundreds of substances in coffee, including antioxidants and polyphenols. The beneficial effects of these substances on glycemic control may compensate for the negative impact of caffeine.<br /><br />Therefore, it is more than plausible that caffeinated coffee acutely decreases glycemic control in large doses over the short term, but improves glycemic control in smaller doses over the long term.Dr. Thomas Haltonhttps://www.blogger.com/profile/05572895847030755799noreply@blogger.comtag:blogger.com,1999:blog-3351611437313995034.post-53361056433147898482012-06-22T17:46:28.599-04:002012-06-22T17:46:28.599-04:00Hi Dr Tom,

In general, the research does differentiate between regular and diet soda. For example, research from Harvard did not find an association between diet soda and weight gain, type 2 diabetes, or coronary heart disease. Interestingly, they did find an association in this paper between diet soda and stroke. The increased risk was identical to that of sugar sweetened soda; a 16% increased risk of stroke when comparing those who consume 1 or more diet sodas per day to those that don't drink any diet soda. However, in the discussion, the authors advised readers to interpret these results with caution. They mention that there is no clear biologic mechanism for this association and that there was a very small number of cases of hemorrhagic stroke among men consuming one or more diet sodas per day. I generally advise my clients to limit diet soda to one or two servings per week. This level of consumption was not associated with increased risk of stroke in this investigation.Dr. Thomas Haltonhttps://www.blogger.com/profile/05572895847030755799noreply@blogger.comtag:blogger.com,1999:blog-3351611437313995034.post-49960744332770538592012-06-15T09:59:35.680-04:002012-06-15T09:59:35.680-04:00Love your blog, thank you for taking the time to p...Love your blog, thank you for taking the time to put it together! On soda consumption, does the research differentiate between sodas containing sugar and those that are diet/no calorie? As a big diet soda consumer, I always assume the headlines on soda consumption health risks are based on the products that contain sugar and calories. Don’t think it’s likely that I’m ever going to go join a 12-step program for a Diet Coke addiction, but if my stroke risk is genuinely 16 percent higher drinking Diet Coke I’d seriously have to cut back. I suspect my attitude that the studies are talking to me as I’m drinking Diet are pretty prevalent. Thanks!Jill Turnerhttps://www.blogger.com/profile/09192395496537148667noreply@blogger.com
