Coffee and Hypertension

Approximately 70 million, or 1 out of every 3 American adults, have hypertension (chronic high blood pressure), a condition that can lead to heart disease, stroke, and kidney disease. Just as many adults have prehypertension, with blood pressure that is higher than normal but not yet high enough to be diagnosed with hypertension.
Coffee, because of its high caffeine content, has long been suspected of contributing to higher blood pressure. Some researchers also speculate that it isn’t the caffeine in coffee that raises blood pressure but one of any number of substances found in both caffeinated and non-caffeinated coffee.
