Medical Forum / General / Cardiology / January 2006Caffeine Limits Blood Flow To Heart Muscle During Exercise
In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude, according to a new study in the Jan. 17, 2006, issue of the Journal of the American College of Cardiology. http://debunkbigpharma.blognation.us/blog/_archives/2006/1/15/1676297.html > In healthy volunteers, the equivalent of two cups of coffee reduced the > body's ability to boost blood flow to the heart muscle in response to [quoted text clipped - 3 lines] > > http://debunkbigpharma.blognation.us/blog/_archives/2006/1/15/1676297.html Caffeine is a drug used to treat apnea in infants. Levels must be monitored. While on the topic of coffee & studies, we were wondering if Starbucks had any hand in funding this one ;-) http://www.foxnews.com/story/0,2933,181639,00.html > In healthy volunteers, the equivalent of two cups of coffee reduced the > body's ability to boost blood flow to the heart muscle in response to [quoted text clipped - 3 lines] > > http://debunkbigpharma.blognation.us/blog/_archives/2006/1/15/1676297.html Ever since I gave up coffee and sugar I noticed that I don't breath as heavy and my heart rate is about 5 beats lower during an intense time trial workout on my bike. besides that I'm much more level headed and think much clearer then when I'm on caffeine.

I'll give up coffee when I'm dead. Susan I know how you feel but try cutting back slowly, there's no reason to go cold turkey like I did. > I know how you feel but try cutting back slowly, there's no reason to > go cold turkey like I did. Are you replying to me? You must learn to quote so folks will know what you're posting about. I don't want to cut back any further, nor do I think any harmful effects are proven, just suggested. Coffee is also rich in health protective antioxidants. Susan Listen I have a 3 month old I don't have time to learn about quotes... > Listen I have a 3 month old I don't have time to learn about quotes... Bye. Susan : I don't want to cut back any further, nor do I think any harmful : effects are proven, just suggested. : : Coffee is also rich in health protective antioxidants. Although coffee is rich in antioxidants it raises homocysteine, CRP and the risk of acute cardiac events. Probably coffee has a negative effect if the dose is higher than two cups a day.

I'm not taking a chance of getting creamed by a truck tomorrow without having had a cuppa joe. Susan |
