喝出健康：咖啡是健康食品

II型糖尿病

     第三点，长期及多数小型研究都认定咖啡含有可阻止II型人体依赖型糖尿病，最近完成的研究发现女性每日饮用3－4杯咖啡可以减少29％发生糖尿病的可能性，男性在这一数字是27％。并且这一数字与饮用咖啡的数成正比，即女性每日饮用10杯以上咖啡，患糖尿病的风险下降80％，而男性为55％。

    来自哈佛大学公共卫生学院研究发现，男性患有II型糖尿病的可能性下降50％，女性为30％，并且与饮用咖啡的杯数成正比。男性每日饮用6杯以上时患糖尿病可能性下降54％，4－5杯时为29％，1－3杯时为7％。女性组显示分别为29％、30％和1％。以上结果也依据其他因素，如年龄、体重和训练情况，发现咖啡是独立因素结果。哈佛的研究与早期杜克的研究有着惊人的一致性结论。

    综上，咖啡内的混合物质是有益的。其他含咖啡因的饮料部具有同等抵抗的能力，不含咖啡因的咖啡的抵抗作用较差，不含咖啡因的茶部具有抵抗作用。

Type II Diabetes
Three major, long-term studies, as well as numerous smaller studies, have confirmed coffee's properties for preventing Type II, or “adult-onset,” diabetes. A new Finnish study found that women who drank three to four cups of coffee a day reduced their diabetes risk by 29%. For men, the reduction was 27%. Those who drank more had higher risk reduction levels -- women who drank ten or more cups of coffee daily lowered their risk by 80%, while men had a 55% lower risk.

This study came on the heels of a study at Harvard University School of Public Health that found the risk of developing Type II Diabetes could be cut in half in men and reduced by 30% in women. Again, the protection proved to be directly proportional to the amount of coffee one drinks. Men who drank six or more cups a day reduced their diabetes risk by 54%, four to five cups by 29% and one to three by 7%. In women, the figures were, respectively, 29%, 30% and 1%. Results were adjusted to offset other risk factors such as age, weight and exercise, and so coffee drinking was isolated as the cause of the benefit. The Harvard study, in turn, confirmed an earlier Dutch study that reached the similarly dramatic conclusions.

Results also suggested that unique coffee compounds contribute to the beneficial effect. Other caffeinated beverages did not offer the same level of protection, and decaffeinated coffee provided lesser protection, while decaffeinated tea offered none.
