Drinking high levels of water can
significantly reduce the risk of coronary heart disease, say
researchers at Loma Linda University whose research was reported
in the American Journal of Epidemiology (Vol. 155, No.9). This
exciting study reveals that drinking high amounts of plain water
is as important as exercise, diet, or not smoking in preventing
coronary heart disease.
“Basically, not drinking enough water
can be as harmful to your heart as smoking ,” warns Jacqueline
Chan, DrPH, principle investigator and lead author of the
article. Dr. Chan and Synnove Knutsen , MD , PhD , second
author, chair of epidemiology department, found that California
Seventh-day Adventists who drink five or more glasses of plain
water a day have a much lower risk of fatal coronary heart
disease compared to those who drink less than two glasses per
The results from this study show that
by drinking more plain water, healthy people without any history
of heart disease, stroke, or diabetes— reduced their risk of
dying from a heart attack by half or more . This is as much or
more than if they had adopted any other well-known preventive
measure, including stopping smoking and lowering cholesterol
levels, increasing exercise or maintaining ideal weight.
Because drinking more plain water is
a simple lifestyle change that anybody can do, this simple
practice has the potential of saving tens of thousands of lives
each year with minimal cost . Neither total fluid intake, nor
intake of other fluids combined showed this reduced risk.
Instead, for women, high intake (5 or more glasses a day) of
other fluids showed a greatly increased risk of coronary heart
“People need to be made aware that
there is a difference , at least for heart health, whether they
get their fluids from plain water or from sodas,” says Dr. Chan.
