Coffee is a popular beverage that is consumed by millions of people worldwide.
However, there has been a lot of debate about whether coffee can increase blood pressure (BP) and contribute to the development of hypertension (high blood pressure).
Caffeine, which is the main active ingredient in coffee, is a stimulant that can increase heart rate and cause blood vessels to narrow. This, in turn, can temporarily raise blood pressure.
However, the effect of caffeine on blood pressure can vary from person to person, and it may depend on factors such as age, sex, and overall health status.
Several studies have looked at the link between coffee drinking and blood pressure.
Some studies have suggested that regular coffee consumption may lead to a slight increase in blood pressure, while others have found no significant association between coffee consumption and blood pressure levels.
Green tea is also a very popular beverage worldwide. Many studies have examined the potential health benefits of green tea, including its effects on blood pressure.
Green tea contains several compounds that may contribute to its potential health benefits, including polyphenols and catechins.
These compounds have been shown to have antioxidant and anti-inflammatory properties, which may help protect the heart and blood vessels.
In a recent study, scientists from Osaka University and elsewhere found that drinking too much coffee could harm people with severe high blood pressure.
But drinking green tea does not have harmful effects.
The study looked at how drinking coffee and green tea affects the risk of dying from heart disease in people with high blood pressure.
High blood pressure means that the force of blood against the walls of the arteries is too high.
Over time, this can cause damage to the arteries and lead to heart disease, stroke, and other health problems.
The researchers studied over 18,000 adults for almost 19 years. They asked the participants about their lifestyle, diet, and medical history, and they also measured their blood pressure.
Based on the blood pressure readings, the researchers divided the participants into different groups: those with normal blood pressure, those with slightly high blood pressure, and those with severe high blood pressure.
The researchers found that among people with severe high blood pressure, drinking a lot of coffee (two or more cups per day) was linked to a higher risk of dying from heart disease.
In other words, people who drank a lot of coffee were more likely to die from heart disease compared to those who didn’t drink coffee or only drank a little bit.
However, this link was not found in people with normal blood pressure or slightly high blood pressure.
This means that people with severe high blood pressure might want to be careful about drinking too much coffee.
On the other hand, the study found that drinking green tea did not increase the risk of dying from heart disease, no matter what the person’s blood pressure was.
This means that drinking green tea is unlikely to increase the risk of heart disease, even in people with severe high blood pressure.
It’s worth noting that this study doesn’t prove that drinking coffee causes heart disease or that drinking green tea prevents it.
It only shows that there is a link between coffee consumption and heart disease risk in people with severe high blood pressure.
More research is needed to understand the relationship between coffee, green tea, and heart disease risk in different populations.
Overall, the study’s findings suggest that people with severe high blood pressure might want to be careful about drinking too much coffee, but drinking green tea is unlikely to increase their risk of heart disease.
As always, it’s important to talk to your doctor about your diet and lifestyle habits to ensure that you’re doing what’s best for your health.
The research was published in the Journal of the American Heart Association and was conducted by Masayuki Teramoto et al.
If you care about blood pressure, please read studies about unhealthy habits that could increase high blood pressure risk, and coconut sugar could help reduce blood pressure and artery stiffness.
