To caffeinate or not to caffeinate?
A recent study using the data of 18,000 people over almost 20 years has found that drinking two or more cups of coffee per day can increase the risk of death in people with severe high blood pressure. But the researchers found coffee made no difference to the risk of death in people with normal blood pressure.
There might be more to your morning drink than you think
There's always a lot of confusing messaging around whether drinking coffee affects our health – particularly when it comes to blood pressure. Adding to the confusion are lots of small and unreliable studies.
But a recent study, published in the Journal of the American Heart Association, involved the data of 18,000 people aged between 40 to 79 (at the start of the study) over almost 20 years.
The researchers found that drinking two or more cups of coffee per day can increase the risk of death in people with severe high blood pressure. However, it made no difference to the risk of death in people with normal blood pressure.
But before you flick the kettle off, it’s worth bearing in mind that, while this was a big study done over many years, it was a population study, which means the researchers have drawn their own conclusions from the data, so their conclusions are not 100% proven.
