Drinking high levels of unfiltered coffee may increase your risk of slightly higher cholesterol levels, according to Harvard Medical School. Drinking at least two cups of coffee per day may also increase your risk of heart disease if you have a genetic mutation that slows down how quickly your body breaks down caffeine. The Harvard School of Public Health, however, examined the relationship between mortality and coffee consumption in two separate studies -- a combined study of about 130,000 volunteers -- and found no correlation between coffee consumption and increased risk of dying from any cause or condition. The 2004 study even accounted for people who consumed up to six cups of coffee every day. (요지는 적어도두잔 이상의 커피는 당신의 심장병 발병의 위험을 높인다.)

 

 

그리고 커피에 관한 문제를 재기하는 아래의 글도 참고하기 바란다.

참고로 나는 하루에 한잔 또는 두잔의 커피를 마시는 사람이다.

몸에 좋기 때문에 마시는 것이 아니고 맛도 좋고 또 통상 우리가 알고 왔듯이 그리 해로운 쪽도 아니라는 나름의 생각으로

마시고 있다. 아래의 글은 왜 해로운가를 가장 잘 설명한 내용이다.

 

PROBLEMS WITH COFFEE DRINKING

 

The detrimental effects of coffee include:

 

·           Caffeine.  Coffee contains some caffeine, a mild but harmful stimulant.  Stimulants whip the adrenal glands into action.  This eventually weakens the adrenals and perhaps the thyroid gland, and this leads to more depletion of a person’s energy.  In large enough amounts, or with chronic use, caffeine from any source is associated with anxiety, irritability, tremors, dehydration, and rebound fatigue and exhaustion.
                  Living on caffeine, as so many young people do today, prevents one from truly relaxing and resting as well.  It can also lead to mental impairment because the mind simply does not function quite as well on stimulants, although it may indeed keep a person awake, which is helpful for school and work.  Thus caffeine in small amounts may be okay, but too often it is overdone, as it is socially acceptable and readily and cheaply available today in coffee, teas, and sodas.

·           Toxic metals.  Coffee contains some lead, cadmium, aluminum and perhaps other toxic metals.  A cup of coffee now and then is not going to add a lot of toxic metals to the body.  However, habitual use can add significant lead, according to our experience with hair mineral testing.  All the toxic metals are quite harmful, so it makes little sense to add more to the body.

·           Rancid oils.  Most ground coffee sold in stores contains oils that are somewhat rancid.  Rancid oils are somewhat toxic for the liver, and are also stimulants.  This is why even decaffeinated coffee will give a person a lift or a ‘high.

·           Toxic chemical additives.  Most decaffeinated coffee and some “coffee blends” contain added chemicals that are used to remove the caffeine, add flavor, or other reasons.  If one wishes to drink decaffeinated coffee, Nestle’s and perhaps one or two other brands claim to use a water decaffeination process without chemicals.

·           Dehydration.  Drinking more than about one cup of coffee always tends to dehydrate the body.  This is one of the effects of caffeine, apparently, and a serious one.  Anyone who drinks coffee must become aware of this possibility, and must drink plenty of either spring water or carbon-filtered tap water to avoid dehydration.

·           Diabetes.  We also find a strong correlation between drinking coffee, metabolic syndrome, dehydration and the development of diabetes.  Many Type II diabetics seem to love coffee, and it worsens their condition significantly.

·           Disturbed digestion.  Coffee, particularly if it is strong, is an irritant to the stomach, and perhaps to other organs as well.  This is the most common complaint about coffee, and the reason most people stop drinking it.
