Studies by the American Medical Association show that drinking coffee properly can effectively reduce the risk of high blood pressure
Coffee contains caffeine, and it was thought that drinking coffee would lead to high blood pressure. How is it actually?
Most importantly, coffee is not the direct cause of high blood pressure. On the contrary, according to the American Medical Association, some studies have reported that it has a risk-reducing effect. Let's carefully study the relationship between coffee and high blood pressure.
What is caffeine?
First, the compound itself caffeine was the first substance isolated from coffee by the German chemist Friedrich Fernando Runge in 1819 (there was an 1820 theory).
It is called caffeine because it is a compound found in coffee.
The role of caffeine
The following effects and side effects are called caffeine.
The action of awakening by stimulating the central nervous system of the brain, antipyretic and sedative effect caused by vasoconstriction, diuretic effect, cardiotonic effect directly acting on the heart, etc. Side effects include dizziness, insomnia and headache caused by overactivity of the central nervous system.
Traditionally, coffee has been thought to cause high blood pressure because it contains caffeine, which acts directly on the heart to increase high blood pressure.
New findings on the relationship between coffee and blood pressure! Is caffeine really the cause?
In fact, blood pressure rises slightly after drinking coffee. However, a health survey of American female nurses was conducted according to an article published in the International Peer-reviewed Medical Journal, the Journal of the American Medical Association (JAMA), published 48 times a year by the American Medical Association. According to the data, it was found that the risk of high blood pressure was not only increased by coffee intake, but also decreased.
At the same time the same study investigated and analyzed the risk of caffeinated tea and cola as well as coffee but although caffeinated coffee decreased the risk of tea increased slightly and was significant in cola. The result is an increase in risk.
In view of this, the causal relationship between caffeine and hypertension has been ruled out.
However, it is not clear which ingredients in black tea or cola contribute to the increased risk of high blood pressure.
Why is coffee said to prevent the risk of high blood pressure? why does coffee contain caffeine but reduce the risk of high blood pressure?
Coffee is known to contain thousands of ingredients, one of which can inhibit the oxidation of bad cholesterol, while polyphenols can inhibit arteriosclerosis. Something like this.
These effects can reduce the risk of high blood pressure. In addition, it is said that taking caffeine can lower blood pressure. This is because caffeine has the effect of constricting blood vessels, so blood pressure temporarily increases, but at the same time, blood through the kidneys increases, and the amount of urine excreted by diuretics increases. The mechanism is to reduce internal excess blood and lower blood pressure.
Drinking coffee may reduce the risk of high blood pressure, but don't drink too much. Caffeine has a variety of effects, but overdose can have side effects. In addition, when adding sugar or milk, please be careful not to consume too much sugar and fat. Enjoy the right amount of quality coffee.
