EDMONTON, Alberta, Aug. 26 (UPI) -- Alberta researchers have found women who don't drink coffee can still get as much buzz and heart benefits from a cup as regular drinkers.
University of Alberta in Edmonton researchers compared how 10 women who drank caffeine daily and 10 "caffeine-naive" women who drank less than two servings per week matched up in heart rate, blood pressure, alertness and the ability to perform a tough mental test after drinking a 350-milliliter-sized coffee. The results were summarized in a Tuesday press release and are being fully published in the latest edition of Nutrition Research.
"The take-home message for women is that whether you are hooked on caffeine or not, if you need a boost, coffee improves your mental alertness and can have a calming effect on your heart rate," said Michael Kennedy, a professor in exercise physiology on the University of Alberta's Faculty of Physical Education and Recreation, lead author on the study.
The only cautionary note from the study came in findings that some regular coffee drinkers began with significantly higher blood pressure, suggesting possible long-term impacts from caffeine.
