Reading the tea leaves about whether drinking green tea is good for you


The result would be great in one’s health by doing a little lifestyle decisions. Taking the stairs for two minutes, Having a simple diet rather than fry your food or refusing that extra glass of wine can all add up to a longer life.

Big result and importance from a small choice, some are wondering whether they should give up their morning cup of coffee in favor of green tea. The evidence on green tea’s benefits is still developing, and we don’t know if it’s the healthier choice. But if you’re looking to make the switch, there is some information that might push you over the bean-leaf divide.

What is green tea?


There are black and green tea but both comes from the same plant, green tea is less processed. Because of this, it has a relatively high concentration of something called catechism. Catechism are part of a bioactive compound known as a flavonoid, which is thought to reduce oxidative stress. According to Howard D. Sesso, an associate professor at Harvard and associate epidemiologist at Brigham and Women’s Hospital a specific catching known as EGCG exists almost exclusively in green tea.

Howard D. Sesso is specializes in researching how diet, particularly flavonoids, can affect health.

Green tea and weight loss.

Of course it’s not cent percent that Green tea may help people lose weight but probably not enough so they can skip a workout or eat an extra piece of pie. According to a review looked at randomized control trials where people were given a preparation of green tea. There was a small amount of weight loss, particularly for Asians, but it was unclear whether it was the caffeine, green tea or ethnicity that was responsible.

Again on another research it was found that when people did lose weight through green tea, they were not drinking actual tea but preparations of concentrated green tea that are equivalent to 15 cups of normal green tea a day. Even with that high concentration, any weight loss was small and unlikely to reach the 5% to 10% of body weight needed to improve cardiovascular health.

Green tea and cancer.

In the year 2009, some experts have conducted a deep review of research on green tea but found insufficient evidence that it prevents cancer. However Observational studies seem to show it slows the growth of precancerous lesions, but experts are at sea  to establish whether or not it reduces the risk of cancer itself. Studies since the review, including a prostate and colorectal cancer randomized trial, have likewise not been able to establish a preventative effect.

Heart health.

It is found by some study and have evidence that green tea helps reduce heart health risk factors, such as by decreasing lipids and lowering blood pressure, but the trials were small and not lengthy enough to show that the tea reduced cardiovascular disease. But sesso said the outcomes are still undetermined, and “they shouldn’t really be translated to disease prevention.”

Green tea is associated with a reduced risk of cognitive decline as found by a Japanese study. Neither black tea nor coffee has been shown to have this effect. But some study look at people who were already drinking green tea, and this type of people may just have other healthy habits that keep their minds sharp. It requires a yearlong clinical trial in which people were randomly assigned to one group or another to establishing a link to green tea. With one group drinking green tea and another a placebo tea. Even with a trial like that, “the logistics can be challenging,” Sesso said. It would be hard and difficult to ensure that the group assigned to drink green tea daily was complying.

So, should I switch to green tea?

Logically green tea is not harmful to drink and the larger studies do share one conclusion: it does not appear to be harmful in one’s health. Sesso has a pragmatic approach. “If it’s something you enjoy, then you should have it. A cup or two of green tea with a healthy diet of fruits and vegetables is great.” As for Sesso, while he thinks there’s some potential to protect health, he personally doesn’t drink either green tea or coffee.
