Many people are aware of the importance of coffee in their lives, especially since there are those who cannot start the day without it.
Despite this, studies are generally split between highlighting its benefits and emphasizing its harms.
Faced with this difference, a new study has found that drinking two or more cups of coffee a day can significantly increase the risk of death from heart disease in some patients.
Japanese researchers found that people whose blood pressure was above 160/100 mm Hg – considered too high – were more likely to die of a heart problem than people with low levels, according to the Daily Mail.
Increases the risk of death
They also stressed that the increased risk doesn’t apply to people with high blood pressure that isn’t considered severe.
And while caffeine is known to be the most important component of coffee and to raise a person’s blood pressure and heart rate for a temporary period of time, it’s still unclear whether drinking coffee consistently could cause long-term increases in blood pressure. blood pressure, cholesterol, or other harmful effects on the heart.
In turn, Dr. Hiroyasu Iso explained that the aim of the study is to determine whether the known protective effect of coffee also applies to subjects with varying degrees of hypertension or not.
The study included nearly 20,000 participants, with more than 12,000 women and more than 6,570 men living in Japan from 1990 to 2009.
Until the researchers found that drinking two cups of coffee a day doubled the risk of dying from heart disease during the study period.
Just one cup
Interestingly, scientists have long debated whether coffee is good for health or not.
Previous studies have found that drinking more cups of coffee each day can reduce all-cause mortality, while others have linked it to cancer.
What’s interesting about the new study is that there wasn’t a significant increase in risk for people who drank just one cup, but people who drank more coffee were younger, smokers and drinkers, had higher cholesterol, lower blood pressure and worse diets.
