Guest guest Posted August 8, 2002 Report Share Posted August 8, 2002 Ria: first of all welcome to the group!! Green tea has many health benefits. It has antioxidants, may help prevent some cancers, and is highly recommended. Coffee, actually has not (so far) proven to be harmful and I drink a cup of it myself every day. We recently posted some anecdotal evidence from a couple of members who feel it may be beneficial in some ways (one member feels it prevents migraine headaches - at least for her). Although you feel you're more hungry after drinking, caffeine is supposedly an appetite suppressant. But perhaps it's an individual thing. For past discussions about coffee or tea, search the archives (the search box on the main page) with the words " coffee " or " tea " . Keep us posted on how you're doing with your CRON program. on 8/8/2002 5:51 PM, Ria Brownlow at riabrownlow@... wrote: > What is the experience of other CRONies > with caffeine?

Guest guest Posted August 9, 2002 Report Share Posted August 9, 2002 The effect of caffeine on health seems a complex issue that is not yet completely sorted out. There has been a recent study that shows caffeine stays in the blood for many hours and that it can increase feelings of stress. An article on this study is at: http://www.healthscout.com/template.asp? page=newsdetail & ap=43 & id=508370 This jibes with my subjective experience and so I don't consume caffeine on a regular basis (only occasionally). Nor do I feel the need for it on a regular basis. However recent posts on caffeine have also shown it to be beneficial for preventing Alzheimers. So if you like caffeine and it doesn't stress you out too much ... it may not be such a bad thing. Excerpt from the above article: " Stressed out? Try kicking caffeine for a week, and you will see your blood pressure, adrenaline levels and overall stress drop, according to a study by Duke University Medical Center. The new research found that the effects of caffeine stay in the body all day long, amplifying any feelings of stress. Moreover, the perception of stress increased for the 47 study participants after they took caffeine tablets. " On the day they had caffeine, their blood pressure was higher throughout the day. And we also found that adrenaline goes up by about 32 percent, " says lead researcher D. Lane, who has studied caffeine for 15 years. " The measurable effects of drinking four cups of coffee are the difference between working a stressful job at a hospital and spending the day at home Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 9, 2002 Report Share Posted August 9, 2002 My BP is already 95 over 64.. If I cut out coffee could it go lower? Think I'll keep drinking my morning Joe.

Guest guest Posted August 9, 2002 Report Share Posted August 9, 2002 Hi All, The article is below. I thought 500 mg was quite a lot of caffeine. .... Caffeine (mg/oz) ... Hot cocoa, 0.3-3; Coca‑Cola, 4, ; Milk chocolate, 1 to 10; Tea, 3.2-10.7/oz; Instant coffee, 10-17; Drip or brewed coffee, 13-30; Espresso, 45-55; One slice chocolate cake, 20 to 30 mg; Anacin or Midol, 32 mg/pill; Excedrin, 65 mg/pill; NoDoz 100 mg/pill ... Cheers, Al. Psychosom Med 2002 Jul-Aug;64(4):595-603 Caffeine affects cardiovascular and neuroendocrine activation at work and home. Lane JD, Pieper CF, -Bute BG, JE, Kuhn CM "OBJECTIVE: This study investigated the effects of moderate doses of caffeine on ambulatory blood pressure and heart rate, urinary excretion of epinephrine, norepinephrine, and cortisol, and subjective measures of stress during normal activities at work and at home in the evening. METHODS: Healthy, nonsmoking, habitual coffee drinkers (N = 47) participated in 3 days of ambulatory study. After a day of ad lib caffeine consumption, caffeine (500 mg) and placebo were administered double-blind in counter-balanced order on separate workdays. Ambulatory blood pressure and heart rate were monitored from the start of the workday until bedtime. Urinary excretion of catecholamines and cortisol was assessed during the workday and evening. RESULTS: Caffeine administration significantly raised average ambulatory blood pressure during the workday and evening by 4/3 mm Hg and reduced average heart rate by 2 bpm. Caffeine also increased by 32% the levels of free epinephrine excreted during the workday and the evening. In addition, caffeine amplified the increases in blood pressure and heart rate associated with higher levels of self-reported stress during the activities of the day. Effects were undiminished through the evening until bedtime. CONCLUSIONS: Caffeine has significant hemodynamic and humoral effects in habitual coffee drinkers that persist for many hours during the activities of everyday life. Furthermore, caffeine may exaggerate sympathetic adrenal-medullary responses to the stressful events of normal daily life. Repeated daily blood pressure elevations and increases in stress reactivity caused by caffeine consumption could contribute to an increased risk of coronary heart disease in the adult population."

I regret I did not find out it was beneficial to me when I was younger. But I also think we need to acknowledge that there is coffe and there is COFFEE... I did not acquire the habit until later in life and do not drink a heavy duty brew as some in my family enjoy. Only a few days ago .. I overheard on the news of a new study which claims that those who consume one cup ..get more of an elevation and that it lasts longer than ... those who drink coffee all day. This does not jive with the study posted in answer to the caffeine question? hmmm sorry I have no more information on the blurb I caught. But like JR... I plan to go with moderation and stick to my morning Joe. Lucy Quote Link to comment Share on other sites More sharing options...
