Caffeinated coffee and tea lowers risk of some heart and metabolic diseases, study shows
A new study found that drinking about three cups of coffee per day was associated with the lowest risk of stroke, coronary heart disease and type 2 diabetes.
There are certain studies that coffee lovers, well, love.
This is one of them: Drinking several cups of caffeinated coffee or tea a day may protect against Type 2 diabetes, coronary heart disease and stroke.
The findings, published Tuesday in the Journal of Clinical Endocrinology & Metabolism, add to existing research suggesting that daily coffee drinkers have better heart health than nondrinkers — provided they don’t drink too much caffeine.
“Caffeine intake at different doses could have different health effects,” the study’s co-lead author Chaofu Ke, an associate professor in the department of epidemiology and biostatistics at Soochow University in China, wrote in an email.

They also looked at responses from about 172,000 people who specified that they drank caffeinated coffee or tea. None of them had a history of cardiometabolic disease — defined by a diagnosis of at least two of the three conditions: Type 2 diabetes, coronary heart disease or stroke — when the study began.
