How Does Green Tea Help In Controlling High Blood Pressure

Green tea and its role in reducing high blood pressure is backed by science.

There are evidences that show the effectiveness of the beverage in helping the blood vessels relax.

The reason behind this effect is the polyphenol content of green tea.

The polyphenol EGCG in green tea helps in lowering high blood pressure. It does this by ensuring the elasticity of your blood vessels so that blood flows properly through them.

It also works towards preventing the formation of deposits in your arteries. As a result, the BP stays normal.

Other kinds of polyphenols present in green tea help in maintaining the right levels of the bad cholesterol in the blood so that the arteries dont get clogged up!

Polyphenols also help in reducing the production of angiotensin in the body. It is a hormone that raises the BP of the body.

Overall, polyphenols have a pivotal role to play in improving the pumping function of the heart and regulating blood flow for good cardiovascular health.

Additionally, it has been found that consuming green tea reduce your total cholesterol levels and LDL .

It is LDL that blocks your blood vessels and increases the chances of a heart attack. Therefore, it is important to keep your LDL levels in check.

In order to reap the blood-pressure-lowering benefits of green tea, studies indicate that you need to consume 5 to 6 cups a day.

However, the consumption of the beverage should not be more than this or else it can lead to adverse effects.

How Green Tea Reduces Blood Pressure

Blood pressure can be grouped up into the three main categories below:

Normal Blood Pressure: Blood pressure readings of up to 120/80mmHg,

Normal High Blood Pressure: Blood pressure readings higher than 120/80mmHg

but lower than 140/90mmHg.

Although this isnt officially classed as high blood pressure, your risk of developing high

blood pressure with readings in this range is much greater than someone who has readings

in the normal blood pressure range.

High Blood Pressure:- Blood pressure readings higher than 140/90mmHg.

Is tea the superhero of beverages?

Studies have shown that tea provides numerous health benefits, and now a new study published in the British Journal of Nutrition suggests it may help lower blood pressure.

Researchers looked at 25 randomized controlled trials to learn more about the link between tea and blood pressure. They found that people who drank tea for more than 12 weeks experienced a reduction of systolic blood pressure by 2.6 mmHg and diastolic blood pressure by 2.2 mmHg.

Lowering your blood pressure by even that small amount benefits your health.;

High blood pressure, or hypertension, can damage arteries, the heart, kidneys, eyes and other organs. Untreated, high blood pressure can lead to heart attack, atherosclerosis , stroke, kidney damage, and vision loss, says Anandh Babu Pon Velayutham, PhD, an assistant professor of nutrition at the University of Utah.

That high blood pressure can wreak such havoc on the body is made even more dangerous as most of the time it displays no symptoms.

Researchers also found that the kind of tea matters. For this study, green tea showed the most significant effects. Black tea came in second place. Previous research suggests that three to four cups of tea daily is optimal. As for caffeinated or decaf, its all the same!;

Teatime Can Be Good For Your Health

“There are really only three drinks that I ever recommend humans consume,” said Dr. Andrew Freeman, director of clinical cardiology and cardiovascular prevention and wellness at National Jewish Health in Denver. “The best is water, and next would be unsweetened tea and unsweetened coffee. Everything else, unfortunately, doesn’t really have any benefit, and many cause significant harm.

“It makes my job very easy when people say, ‘What should I drink?'”

Studies show tea consumption, along with a heart-healthy diet, may improve some brain function, ward off some cancers, defend against heart disease by boosting “good” cholesterol and help with weight control. It may even reduce bad breath.

A 2018 study in the Journal of the American Heart Association found that tea appears to slow the natural decrease in heart-helping HDL cholesterol as a person ages. Those findings pair well with previous research that suggests tea also reduces low-density lipoprotein, or LDL, known as “bad” cholesterol. Studies also show tea may reduce blood sugar levels and help prevent type 2 diabetes.

Black and green tea are the most popular kinds, accounting for 99% of the tea consumed in the United States. Both kinds of tea are loaded with caffeine and antioxidants called polyphenols, which are linked to lower blood pressure and better heart health. There are some slight differences; black tea, for example, contains more caffeine while green tea has a slightly better antioxidant profile.

Amazing Catechins Keep Your Heart Healthy

Green teas contain organic compounds known as polyphenols, which are a type of antioxidant. Polyphenols can be broken down into many subcategories, including a group called flavonoids, which contain catechins. Catechins are tiny powerhouse antioxidants found in green tea that destroy free radicals and improve your vascular system.

Catechins help to improve endothelium-dependent vasodialation, which means it helps to increase the size of your arteries, lowering your blood pressure. Arteries narrow with age when the endothelium lining of arteries cease to function properly. Because of this, different medical conditions such as plaque build-up can occur, which in turn raises blood pressure.

To get the most from catechins, be sure to steep your tea slightly longer than you normally would. The longer the tea steeps, the more catechins it will contain.

Safely Drinking Green Tea

If you enjoy drinking green tea, then you can likely drink up to 3 to 4 cups a day safely, Angelone says. If you have high blood pressure, you should check your blood pressure regularly when first getting in the habit of drinking green tea. Choosing decaf green tea can help avoid any possible effects from caffeine, she adds. NCCIH also notes that green tea manufacturers only have to report the added caffeine on green tea product labels, not what is naturally occurring.

Electrical Activity In The Brain

KCNQ5 also exists in the membranes of nerves in the brain, where it helps regulate electrical activity and signal transmission.

People with a disorder called epileptic encephalopathy have a version of the channel protein that does not respond effectively to voltage changes, which leads to frequent seizures.

The study authors point out that catechins can cross the blood-brain barrier, which prevents larger molecules, including some drugs, from entering the brain.

In theory, drugs modeled on catechin molecules could, therefore, help correct the cause of epileptic encephalopathy.

Discovery of their ability to activate KCNQ5 may suggest a future mechanism to fix broken KCNQ5 channels to ameliorate brain excitability disorders stemming from their dysfunction, the researchers conclude.
