Is Japanese tea suitable for preventing high blood pressure?

Hypertension is classified as an adult disease, and it is said that it is especially common among Japanese people who ingest a large amount of salt from their diet. This article introduces why Japanese tea is said to be good for preventing high blood pressure.

Why Japanese tea is good for preventing hypertension

There are all kinds of Japanese teas, but if you want to take it to prevent high blood pressure, green tea is recommended. This is because the ingredients contained in green tea are thought to be useful in preventing high blood pressure.
Let's take a look at the relationship between the ingredients contained in green tea and high blood pressure.

Catechin

When you drink strong green tea, do you ever feel that it is a little bitter? Actually, this bitterness is due to the catechins contained in green tea.
Catechins have an antioxidant effect and are said to help prevent arteriosclerosis by removing active oxygen, which in turn is said to help prevent high blood pressure.
This is because when arteriosclerosis occurs, the flow of blood becomes slow, which increases the risk of blood pressure rising, and catechins are said to be able to prevent this from happening.
In other words, people who consume green tea every day are less likely to develop high blood pressure than those who do not.

How to drink Japanese tea to prevent high blood pressure

It would be great if we could prevent high blood pressure with the green tea we drink every day, but in order to efficiently take in the catechins from green tea, it is important to take certain measures.
Here are some tips on how to get the best catechins from green tea and what to keep in mind when drinking green tea.

Catechins are extracted at high temperatures

Catechins are easily extracted at high temperatures, but immediately after pouring boiling water into a teapot, the catechins have not yet been extracted.
If you want to drink green tea to prevent high blood pressure, wait about a minute to a minute and a half after pouring boiling water into it before drinking it.
In addition, the amount of catechins extracted from room temperature or cold water is greatly reduced, so please use boiling water when brewing green tea.

Watch out for this when drinking green tea!

Basically, you cannot make and store green tea.
This is because green tea oxidizes quickly and the quality of the tea will change after a few hours of brewing.
Whenever possible, drink green tea immediately after brewing, or if you want to drink it cold, store it in the refrigerator after it has cooled down and drink it the same day.
If you want to drink it cold, store it in the refrigerator after it has cooled down.
Even if you "add too much tea leaves" or "still have a dark color", you can brew it up to 2 times, and drinking after that is not recommended, so please refer to it.
