Study Finds Drinking Coffee May Lower Risk of Premature Death and Heart Disease
Coffee is one of the most commonly consumed beverages worldwide. A recent study suggests that drinking three to four cups of coffee per day may be associated with a lower risk of premature death and heart disease, when compared with drinking no coffee.
For their analysis, researchers from the University of Southampton examined data from 201 studies that used primarily observational data. This made it difficult to determine a cause and effect relationship. However, after examining the data, the researchers did find that drinking coffee was generally associated with a lower risk of death and heart disease. The only groups this did not apply to were pregnant women and women at risk of fracture.
The researchers also found that the largest reduction in risk was seen in participants who drank three cups of coffee per day, when compared with drinking zero cups. Drinking more than three cups was not associated with any harm to the body, but the benefits were less pronounced.
Associations were also noted between drinking coffee and lower risk of prostate, endometrial, skin, and liver cancers as well as type-2 diabetes, gallstones, and gout. The researchers also noted associations between drinking coffee and lower risk of Parkinson’s, depression, and Alzheimer’s disease.
Benefits were also associated with decaffeinated coffee, but the evidence was not as strong as it was for caffeinated coffee.
The study was published on November 22, 2017, in BMJ.
The health benefits associated with coffee are generally attributed to its polyphenol content. Previous studies have linked polyphenol intake with a variety of health benefits, including helping with weight management and reducing inflammation.
