Drinking coffee may lower women’s risk of stroke by 25%


Coffee, one of the most popular drinks in the world, contains large amounts of antioxidants that provide health benefits to humans. Various researches have been performed over the years to determine how coffee drinking affects humans.  A new study published in Stroke: Journal of the American Heart Association found that women who drank more than one cup of coffee a day had about a 25% lower risk of stroke.  According to the American Heart Association, stroke is the third largest cause of death in the United States, and it is the leading cause of serious, long-term disability.  

About the Study
Susanna Larsson, lead author of the study and a researcher in the division of nutritional epidemiology at the National Institute of Environmental Science in Stockholm, Sweden followed 34,670 women ages 49-83 for an average of 10 years. The results showed –

  • Women who drank more than a cup of coffee a day had a 22% to 25% lower risk of stroke than those who drank less cup of coffee. 
  • Women who drank one to five or more cups of coffee a day showed similar benefits in stroke reduction.  
  • Drinking more coffee did not find to reduce stroke risk any further. 

The research did not provide information whether participants consumed regular or decaffeinated coffee, but the authors say the number of people who drink decaf in Sweden is very low.

Susanna Larsson said “More research is needed before implications for public health can be considered.”

Cathy A. Sila, MD, the George M. Humphrey II Professor of Neurology and the director of the Stroke & Cerebrovascular Center at the Neurological Institute Case Medical Center of Case Western Reserve University School of Medicine in Cleveland, Ohio said “It is too early to say whether anyone should drink more or less coffee to lower their stroke risk.”

It is well known that high blood pressure is the most important risk factor for stroke and has been called the silent killer.  Other important risk factors are high cholesterol, diabetes and irregular heart conditions (called atrial fibrillation).  The best way to prevent the risk of stroke is to have a diet rich in fruits and vegetables, low in sodium and high in potassium.
