Research shows that coffee may actually decrease the chances of getting type-2 diabetes. In addition, coffee is no longer felt to be a risk factor for high blood pressure.
A 12 years study of 155,000 women found that drinking caffeinated cola may be associated with an increased risk of high blood pressure. However, the same causal relationship was not found with caffeinated coffee. In fact, the study suggested that women who drink caffeinated coffee may actually have a reduced risk of high blood pressure.
A 1989 Norwegian study of 30,000 middle-aged men and women demonstrated that drinking more than one cup of coffee a day is positively correlated with a reduction on both systolic and diastolic blood pressure.
In other words, people in a high-risk group of hypertension who drink more than one cup of coffee a day tend to have lower blood pressure than people who do not.
