Experts believe that drinking coffee can save lives. Coffee is a "double-edged sword".
Coffee is a double-edged sword. Some experts believe coffee is a dangerous irritant, others believe drinking coffee saves lives. A new Swedish study published in the American Journal of Epidemiology found that drinking two cups of coffee a day significantly reduced the risk of stroke.
The comprehensive analysis of coffee's health benefits by Karolinska Institute scientists confirms that coffee drinking plays an important role in preventing stroke attacks. The scientists analyzed eight coffee and health studies completed between the 1960s and 2011, involving a total of 500,000 participants. The new study found that participants who drank two cups of coffee a day had a 14 percent lower risk of stroke in the brain. Those who drank three to four cups of coffee a day had a 17 percent lower risk of stroke. However, higher daily coffee intake does not continue to exert the stroke prevention effect of coffee. Caffeine addicts who drank more than six cups of coffee a day reduced their risk of stroke by only 7 percent.
The researchers analyzed that a variety of antioxidants in coffee have a protective effect on brain blood vessels, which prevents bad cholesterol from damaging brain blood vessels. But scientists caution that coffee contains a variety of compounds that have both health benefits and adverse health effects. For example, people at high risk of high blood pressure should not drink more coffee, because coffee has the effect of raising blood pressure.
