Green tea and black tea, which one is more helpful to reduce blood pressure?

According to popular science China, how difficult it is to reduce blood pressure?Presumably many friends of high blood pressure can experience it ~

The reduction of each millimeters of mercury is often a "gift" that can only be found after taking medicine, healthy diet, and exercise for a long time.

But weird, scientists have discovered such a group of relaxed friends who lower blood pressure -they just did one more thing every day, and they harvested a significant antihypertensive effect after 12 weeks [1].

This little thing is

They found that after long -term tea drinking, the average systolic and diastolic pressure decreased by 1.8mmHg and 1.4mmHg, respectively.Then the question is here-

01

There are tens of millions of tea

Which one is the most lowered?

Part.1

Although the category of tea on the market has dazzled people, green tea, black tea, oolong tea, white tea, yellow tea, chrysanthemum tea …

But unfortunately, most of the current research on "drinking tea and blood pressure" is still aimed at "black tea" and "green tea".Researchers from the Fuwai Hospital of the Chinese Academy of Medical Sciences have published a contribution analysis in the British Nutrition Magazine [1]:

They comprehensively analyzed 25 related studies and 1476 subjects to conclude that they concluded– came to conclusions–

Those who drink green tea have a significant shrinkage of 2.1mmHg, and the diastolic blood pressure is significantly reduced by 1.7mmHg;

For those who drink black tea, the systolic blood pressure is reduced by 1.4mmHg, and the diastolic pressure is reduced by 1.1mmHg.

From this point of view, it seems that the effect of drinking green tea for a long time is better.

Coincidentally, another contingent analysis from foreign scholars also found that when viewed by the type of tea, the antihypertensive effect of green tea is more obvious than black tea [2].

02

Drink frequently to be effective

Although many studies believe that drinking tea can help reduce blood pressure.

But this does not mean that friends who do not have the habit of drinking tea, you can quickly reduce blood pressure after seeing this article, after seeing this article, after all … this is tea, not medicine ~

Researchers at Fuwai Hospital found that acute ingestion tea has no effect on systolic and diastolic blood pressure.When drinking tea for more than 12 weeks, the antihypertensive effect will be obvious (the systolic blood decreases 2.6mmHg, and the diastolic pressure is reduced by 2.2mmHg) [1].

In addition to "long -term", some scholars say that the frequency of tea drinking is also related to the effect of decreased blood pressure.HODGSON and others have evaluated the impact of long -term regular tea drinking on the blood pressure on elderly women, and a total of 218 women over 70 years of age have been included in this research.The results of the study show that the intake of tea is significantly reduced by the significant reduction of high pressure (systolic blood pressure) and low pressure (diastolic pressure).Tea intake increases by 250 ml/day (one cup) and a decrease in high pressure (systolic blood pressure) 2.2 mmHg and diastolic blood decreases by 0.9 mmHg related [3].This shows that often drinking tea may have an advantageous impact on the blood pressure of elderly women [3].In addition, a study involving 4,579 elderly people, the blood pressure and tea consumption of the elderly population in Jiangsu, China found that (after adjusting a series of influencing factors such as age, gender, lifestyle, etc.)Systolic pressure related.Among all the subjects, there are also significant negative correlation between the diastolic pressure and the frequency of tea drinking [3].

It seems that the tea in the cup is not water, but a cup of antihypertensive water

In the end, although many studies have shown that drinking tea can help lower blood pressure, it is also necessary to remind everyone that although drinking tea is good, but not too strong.

After all, strong tea not only drinks bitterness, but also in the "Guidelines for Hypertensive Education" clearly states that the type of "less consumption/not eating" ~ [4]
