How much coffee is too much coffee?

In recent years, an increasing number of studies have discovered that drinking a few cups of coffee per day significantly benefits one’s health. Now, a new study has discovered that drinking two to three cups of coffee daily may help prevent heart disease and may even help prolong life.

The researchers analysed data from nearly 400,000 healthy people in their fifties who were followed for a decade. They discovered that drinking two or three cups of coffee daily was optimal, with participants having a 10% to 15% lower risk of developing coronary heart disease, heart failure, or an irregular heartbeat.

The benefits persisted whether participants drank instant or ground coffee. On the other hand, decaffeinated coffee did not provide the same health benefits.

Additionally, the researchers analysed people who had already experienced some heart problems and discovered that drinking two to three glasses of coffee per day was associated with a lower risk of death when compared to not drinking at all, despite doctors’ concerns that caffeine stimulation could exacerbate heart problems.

“Our findings suggest that daily coffee consumption should be included in a healthy diet for people with and without heart disease,” said Professor Peter Kistler, the study’s lead author and an expert at Melbourne’s Baker Heart and Diabetes Institute.

What is the composition of coffee?
Coffee beans contain over a hundred compounds that have been linked to decreased inflammation and increased metabolism.

The researchers speculated that these mechanisms may contribute to coffee’s ability to improve heart health. These compounds have been shown to decrease inflammation and increase insulin sensitivity, which results in a decrease in blood sugar and an increase in metabolism. Caffeine also suppresses appetite, which may result in a lower rate of obesity and the associated health problems.

The researchers analysed data from the UK’s BioBank, a database that contains health records for over half a million Britons who have been followed for a decade. Participants completed a questionnaire in which they were asked about their daily coffee consumption, among other things. The first study examined data on 382,535 people with an average age of 57 and no history of heart disease.
