Coffee for health
An Arabian legend tells of a goatherd who made a beverage from berries growing on strange shrubs, and after drinking it experienced extraordinary lucidity and wakefulness. The shrubs were said to have been planted by the descendants of the Queen of Sheba, who came from Ethiopia, where Coffea arabica originates.
The Forbes article adds, "Despite earlier beliefs that coffee has negative health effects, it is becoming increasingly clear that the opposite is in fact the case. Coffee consumption is now being linked to the lowered occurrence of cases of certain cancers and chronic diseases. One study, conducted by the Harvard University School of Public Health, shows that the risk for developing Type II diabetes is lower among regular coffee drinkers. There are even studies that link coffee to added endurance during physical workouts."
Many of coffee's healthful qualities come from its abundance of antioxidants. The health benefits of coffee include:
--Reduced risk of cancer, especially colon and bladder
--Increased good (HDL) cholesterol; decreased bad (LDL) cholesterol
--Reduced risk of heart disease
--Reduced risk of strokes
--Reduced incidence of kidney stones and liver cirrhosis
--Reduced incidence of Type 2 diabetes
--Reduced risk of Parkinson's disease
--Decline in levels of depression and anxiety
--Asthma relief
--Relief of malaise associated with the common cold
--Increased speed of information processing, alertness, energy, endurance, motivation, and concentration (with important implications for night shift workers and for drivers, as well as anyone wanting to remain productive on the job after lunch)
--Soothes headaches (caffeine is a vaso-constrictor--that's why it's a major ingredient in headache remedies)
--Science has debunked myths that caffeine contributes to breast cancer, bladder cancer, ulcers, indigestion, and osteoporosis
--Harmless during pregnancy; children are no more sensitive to caffeine than adults
--Last but not least, caffeine stimulates metabolism
Not to neglect tea or tea drinkers: according to Tribute to Tea online, "Tea's rising popularity has encouraged entrepreneurs to open tea shops around the country, even in rural communities such as Newton, N.J.; Carefree, Ariz.; and Anoka, Minn., where people sit for a while and enjoy a pot or a cup. And even in coffee-loving Seattle."
Tea holds its own in the health department, too: it's a source of flavonoids; vitamins A and B6, thiamin, and riboflavin; nicotinic, pantothenic, ascorbic, and folic acids; manganese, potassium, and fluoride. Tea is being studied for its benefits in enhancing immune function, lowering LDL and raising HDL levels, reducing blood pressure, thinning blood, reducing the risk of heart attack, stroke, and cancer, increasing longevity, aiding digestion, and promoting dental health.
What about the addiction question? Neither coffee nor other caffeine-containing products are classified by drug dependence experts as addictive. Coffee drinkers do not exhibit the behaviors that define addiction--severe withdrawal symptoms, tolerance, the need to consume the addictive substance at all costs, and antisocial behavior including crimes.
