and Disease Prevention
by Yi-Fang Chu
Currently the second most traded commodity in the world, just behind
crude oil, coffee has an unquestioned significance in the lives of
billions of people. This book comprehensively surveys current research
on the health effects of coffee consumption, both good and bad, from
protecting against diabetes and cancers to causing anxiety and
to be the first volume to recap what is presently known about the
bioactive effects of the many compounds in a cup of coffee, the book
begins with chapters on the history and chemistry of coffee followed by
separate sections on the potential benefits and the possible concerns
about the beverage.
Coffee and Blood Pressure
Coffee has long been suspected
to increase blood pressure in healthy
subjects. Intake of 200-250mg caffeine (2-3 cups of coffee) is
associated with an early elevation of systolic blood pressure and
diastolic blood pressure.
The most recent meta-analysis
of 16 randomized control trials that assessed coffee and caffeine
intake revealed that regular coffee and caffeine intake is associated
with blood pressure elevation; however, the increase in blood pressure
produced by caffeine tablet ingestion was two to three times higher
than that produced by regular coffee consumption despite equal mean
doses of caffeine. This meta-analysis showed that the blood pressure of
participants was higher in studies using caffeine tablets, suggesting
that caffeine may induce the pressor effect, but other compounds
present in coffee may modify this effect.
Taken together, these results
show that coffee raises blood pressure acutely, but there is
insufficient evidence to show that long-term coffee consumption causes
Coffee is only one
component of the diet that may be preventative. Other studies support a
role for the Mediterranean diet, which is rich in fruits, nuts,
legumes, cereals, and fish, and indicate the importance of physical
activity in preventing or delaying cognitive decline with aging.
Alzheimer's disease is
not curable but is preventable... Given the high coffee consumption
worldwide and the aging population in many countries, coffee's apparent
ability to protect cognition could have important implications.

America’s thirst for coffee peaked in 1946,
when everyone in the U.S. drank about 48 gallons a year on
average, according to the U.S. Department of Agriculture. That’s
more than twice current consumption.
|Coffee contains a number
of compounds that contribute to the flavor and bioactivity of the brew.
Complex reactions take place during roasting at high temperatures and
modify considerably coffee's chemical composition, with some beneficial
compounds degraded and some created. A small amount of harmful
compounds is also created during roasting; however, the beneficial
compounds appear to predominate.
To obtain a
coffee, it is important to consider every aspect of coffee production,
starting with high-quality seedsroasted to light-medium to dark-medium

coffees contain relatively high amounts of antioxidant compounds
compared with other food products, a considerable amount of niacin, low
acylamide content, and typically no PAHs.
Decaffeinated coffee is
indicated for individuals sensitive to caffeine's effects and those who
wish to use coffee and an additional tool to reduce the risk of type 2
