Drinking three cups of coffee a day cuts risk of dying from heart disease by up to 17%, study shows
- Experts from Semmelweis University have studied how coffee can affect heart health
- They grouped 468,629 British adults by their daily coffee consumption
- They found that drinking three cups of coffee a day lowered the risk of stroke by 21%
- Higher coffee consumption was also not associated with negative outcomes
Your risk of death from heart disease can be reduced by up to 17 percent with moderate coffee consumption — up to three cups a day — a study has shown.
Researchers led by Semmelweis University in Budapest examined the link between coffee habits and heart attack and stroke rates.
They found that moderate coffee consumption can also reduce the risk of stroke by up to 21 percent compared to people who don’t drink coffee at all.

WHAT ARE THE HEALTH BENEFITS OF COFFEE?
Scientific studies on the health effects of coffee are ongoing and have claimed in the past that the drink has quite significant health benefits.
Reduces the risk of premature death
Research by the National Cancer Institute in the US last year found that people who drink six or seven cups of coffee a day were 16 percent less likely to die from a disease within a 10-year period than those who didn’t.
Less chance of depression
Another study conducted by the Harvard School of Public Health found that women who drank four or more cups of coffee a day were 20 percent less likely to suffer from depression.
Women have a higher pain threshold
British scientists at Goldsmiths, University of London, found that women who drank coffee — 250mg of caffeine to be precise — had a higher pain threshold than those who didn’t.
Lower Type 2 Diabetes
The Institute for Scientific Information on Coffee said last year it had gone through nearly 30 studies of nearly 1.2 million people to find that drinking three or four cups of coffee a day cut the risk of developing type 2 diabetes by 27 percent. would decrease.
“This is the largest study to systematically assess the cardiovascular effects of regular coffee consumption in a population with no diagnosed heart disease,” said author and cardiologist Judit Simon of Hungary’s Semmelweis University.
‘Our results suggest that regular coffee consumption is safe, as even a high daily intake was not associated with adverse cardiovascular outcomes and all-cause mortality after a 10- to 15-year follow-up.
“In addition, 0.5 to 3 cups of coffee a day was independently associated with a lower risk of stroke, death from cardiovascular disease and death from any cause.”
In the study, Dr. Simon and colleagues measured the health and coffee consumption habits of 468,629 adults over an average 11-year period.
Data for the study was collected from the UK Biobank – a large-scale database containing detailed genetic and health information on half a million participants.
The team divided the subjects into three groups based on their daily coffee intake: 22 percent reported not drinking coffee regularly, 58.4 percent drank one-half to three cups a day, and 19.5 percent drank more than three cups.
At the start of the study, none of the participants had any sign of heart disease — and the cohort had a mean age of about 56.2 years.
The researchers found that moderate coffee consumption — that is, up to three cups a day — was associated with a 12 percent lower risk of death from any cause and a 17 percent lower risk of death from cardiovascular disease, in particular.
In addition, the team found that moderate coffee drinkers appeared to have a 21 percent lower risk of stroke than those who drank no coffee at all.
To investigate possible mechanisms that could explain these associations, the team next analyzed the heart structure and function of 30,650 participants using data collected by magnetic resonance imaging or MRI scans.
‘The imaging analysis indicated that compared to participants who did not drink coffee regularly, everyday consumers had a healthier and better functioning heart,’ explains Dr Simon.
‘This was consistent with reversing the damaging effects of aging on the heart.
“Our findings suggest that coffee consumption of up to 3 cups per day is associated with beneficial cardiovascular outcomes,” concluded Dr. Simon.
“While further studies are needed to explain the underlying mechanisms, the observed benefits may be explained in part by positive changes in the structure and function of the heart.”
The full findings of the study were presented at the 2021 Congress of the European Society of Cardiology, which will be held virtually from August 27-30.
THE CAUSES OF A BATTLE
There are two main types of stroke:
1. ISHEMIC BATTLE
An ischemic stroke — which accounts for 80 percent of strokes — occurs when there is a blockage in a blood vessel that prevents blood from reaching part of the brain.
2. HEMORRHAGIC BATTLE
The more rare, a hemorrhagic stroke, occurs when a blood vessel bursts, flooding one part of the brain with too much blood while depriving other areas of adequate blood supply.
It can be the result of an AVM or arteriovenous malformation (an abnormal cluster of blood vessels) in the brain.
Thirty percent of patients with subarachnoid hemorrhage die before reaching the hospital. Another 25 percent die within 24 hours. And 40 percent of survivors die within a week.
Age, high blood pressure, smoking, obesity, sedentary lifestyle, diabetes, atrial fibrillation, family history, and history of a previous stroke or TIA (a mini-stroke) are all risk factors for having a stroke.
SYMPTOMS OF A BATTLE
- Sudden numbness or weakness of the face, arm, or leg, especially on one side of the body
- Sudden confusion, difficulty speaking or understanding
- Sudden vision problems or blurred vision in one or both eyes
- Sudden trouble walking, dizziness, loss of balance or coordination
- Sudden severe headache with no known cause
Of the approximately three in four people who survive a stroke, many will have a lifelong disability.
This includes difficulty walking, communicating, eating, and completing daily tasks or chores.
Both are potentially fatal, and patients require surgery or a drug called tPA (tissue plasminogen activator) within three hours to save them.
