Regular coffee consumption has been associated with a lower risk of Type 2 diabetes mellitus and other cardiovascular risk factors such as obesity and depression.
A Harvard University study published in Circulation in 2015 found that people who drank three to five cups of coffee daily were less likely to die prematurely from any cause.
The study also found that they were specifically less likely to die from heart disease and stroke compared to people who drank little or no coffee. And drinking more than five cups of coffee per day didn’t favourably affect risk of death.
An analysis published in 2013 in Circulation compiled the results of 36 studies on coffee that included more than one million patients. Researchers concluded that people who drank coffee in moderation were significantly less likely to develop cardiovascular disease than those who didn’t drink coffee.
A newly published study (2015) of South Korean coffee consumers found moderate drinkers are less likely to have signs of blocked arteries than people who drank no coffee — or those who drank five or more cups a day.
The study’s participants who consumed between 3 and 4 cups of coffee per day had the lowest risk of clogged arteries developing, Dr. Yoosoo Chang of Kangbuk Samsung Hospital in Seoul and colleagues found.
