It is known that the coffee It is one of the most popular drinks in the world, as it is estimated that around two billion cups are consumed every day. But around coffee, for years it has also been studied whether it affects health, especially in those people with hypertension as much as possible cardiovascular risk.
A study found that people who drink 3 to 5 cups of coffee a day have a lower cardiovascular risk of those who take less. However, as a counterpart, other research suggests the impact could be negative.
A study of Trusted source found a link between excessive coffee consumption and an increased risk of mortality related to cardiovascular disease among people with severe hypertension.
Indeed, further work on the close relationship between coffee consumption and blood pressure could help develop preventive strategies for cardiac risk.
Along these lines, medical scientists have evaluated this very issue and found that regular coffee consumption is associated with multiple measures of lowering blood pressure, according to the study appearing in Nutrients.
Research on coffee consumption and blood pressure
The researchers evaluated the health data of 720 men and 783 women of the Brisighella Heart Study (BHS), an arduous mission that started in 1972 and involves the rural population of a small town in northern Italy.
Every four years the analyzes of the participants were compared and some of the indices reflected by the group were compared below:
- 14.6% do not drink coffee regularly
- 27% drink a cup of coffee a day
- 48.3% drink two coffees a day
- 6.6% drink three coffees a day.
- 3.5% drink more than three cups of coffee a day
The researchers found that those who drank two cups of coffee a day or more than three cups had significantly lower systolic blood pressure than those who didn’t drink coffee.
Systolic blood pressure measures the pressure in your arteries when your heart beats.. And so it is that higher systolic blood pressure levels are linked to an increased risk of stroke and heart disease.
They also found a correlation between more cups consumed and other measures of blood pressure, including lower peripheral pulse pressure (PP), the rate at which blood moves through the body, spreads MedicalNewsToday.
But they noticed drinking coffee did not affect arterial stiffnessthe gradual loss of elasticity of the arteries, which implies cardiovascular events, dementia and death.
“Those who drank 2 cups of coffee had an average of 5 points lower blood pressure than those who drank no coffee. The effect was greater for those who drank more than 3 cups, with an average drop of 9 points”, he confides Yu Ming Nicardiologist of the MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valleyto the Medical News Today website.
He adds, “This trend toward lower blood pressure with higher coffee consumption persisted for different types of blood pressure measurements.”
How coffee affects a hypertensive person
He Dr. Robert Segal, founder of Manhattan Cardiology, Manhattan medical offices and co-founder of LabFinder who was not involved in the study, also contributed.
“In the long run, regular coffee consumption may lead to a small reduction in blood pressure due to improved insulin sensitivity and antioxidant effects,” she said.
He has also joined the debate on coffee consumption and high blood pressure John Higginssports cardiologist at the UTHealth Science Center in Houston, McGovern Medical School and the Memorial Hermann Ironman Sports Medicine Institute.
“THE flavonoids increase the production of nitric oxide, which helps the blood vessel wall to dilate and lower blood pressure“, revealed.
He added, “As well as other minerals like magnesium, potassium, niacin and vitamin E, which can fight aging blood vessels by blocking the harmful oxidation process and reducing damage.”
The article also collected the opinion of Shannon Hoos-Thompson, Cardiologist at the University of Kansas Health System: “This topic has been analyzed for years all over the world. The general conclusion is that regular coffee consumption in moderation is safe without a clear benefit or risk to cardiovascular health.
Search limits
Although it may seem strange, one of the limitations that emerged concerns the study did not mention the exact amount of coffee that made up “one cup”.
And the investigator commented that he didn’t even know the concentration, and whether or not the drinks contained caffeine further limits the findings.
Not to mention another fundamental aspect: coffee intake was self-reported. And it can always happen that some white lie (or more) is circulated.
Another aspect to take into consideration is that the scientific work has been carried out only in brisighella, city in the province of Ravenna, in northern Italy. So they definitely stuck with it similar diets, habits, and even geneticswhich causes some bias.
“Italians mainly drink espresso-based coffeewhich is smaller and lighter than coffee brewed, for example, in the USA,” Dr. Hoos-Thompson did not overlook either.
“Not even coffees sweetened with flavored syrups and the various roasting and preparation methods affect the levels of healthy antioxidants in coffee. The failure to explain the totality of these differences continues to prevent a conclusive determination of the health benefits of coffee”, he concluded.
