Green tea has been a subject of intensive research for the past couple of decades. The majority of studies have shown that regular consumption of green tea can have positive effects on the health of our bodies, particularly disease prevention. Green tea has been hailed for its cancer fighting properties as well as prevention of heart disease.
Although many of the benefits of green tea have been lab-based, there are a few real-world examples of the health benefits of green tea. For instance, populations that traditionally consume green tea (such as those in the Far East) also have lower rates of degenerative diseases compared to those that do not consume green tea regularly.
Fact is, the few large-scale studies carried out on humans have shown green tea’s positive impact in preventing cancer and heart disease. Moreover, most health experts agree that green tea contains some important anti-oxidants as well as other compounds that lead to good health.
That said, here is a detailed look at the specific health benefits of green tea. You can click here at the official site to know about the health benefits. The drinking of the green tea will provide the best results. The cost is less in comparison to the other pills.
Most of green tea’s health benefits stem from its high amounts of anti-oxidants. Green tea contains a high amount of catechins (anti-oxidants) that scavenge DNA-damaging free radicals and destroy them. Besides damaging DNA, free radicals are responsible for proliferating cancer and can lead to blood clots as well. Similar anti-oxidants can also be found in berries, dark chocolate, and red wine.
Green tea undergoes minimal processing – instead of fermenting the leaves as with black tea, green tea leaves are simply withered and steamed. This helps to preserve the unique catechins in green tea, especially epigallocatechin-3-gallate (EGCG).
There’s a debate on the amount of green tea that you need to consume before realizing its health benefits, given that the body doesn’t always use EGCG because it is not readily available. But health experts stress that it is constancy that matters most.
Various studies have shown that green tea can inhibit the growth of cancerous cells and can also regulate cell growth. Although studies in humans have not been as extensive, one research study in mice showed that the synthetic form of EGCG can greatly shrink prostate cancer tumors.
Other similar observations have been noted in humans too, especially with populations that have green tea as a dietary mainstay. In particular, a Japanese study on 500 women with stage I and II breast cancer showed that the chances of cancer recurrence after surgery were greatly reduced by increased consumption of green tea before surgery.
Another Chinese study revealed that high consumption of green tea greatly reduced the risk of esophageal cancer, stomach cancer, pancreatic cancer, prostate cancer, and colorectal cancer.
It is generally agreed in the scientific world that increase in the consumption of green tea (say by 2 cups a day) reduces the risk of many types of cancer.
Heart Health Benefits
Various studies have been carried out both in the East and the West about the benefits of green tea on heart health. Although the results slightly vary (depending on many factors such as age, lifestyle, gender, and more), one common trait that emerged is that green tea consumption reduced clogging of the blood vessels. Of course, green tea consumption has to be complimented with a healthy diet in order to realize optimal benefits to heart health.
The antioxidants in green tea are dilators as well, helping to keep blood vessels healthy and flexible. It is this effect that leads to the general improvement of the heart’s health and prevention of other heart issues.
Green tea has also been shown to lower LDL and fight obesity, which are both risk factor of heart diseases and diabetes. A study in Japan and another one in the Netherlands revealed that green tea led to weight loss by suppressing appetite, along with eliminating the health risks associated with obesity. And it seems like the more green tea you consume alongside your weight loss plan, the more weight you lose, according to another Japanese study.
That said, it’s worth noting that most of these health benefits of green tea are realized from drinking it, not taking it as a supplement. Another important factor is constancy; green tea has to be consumed regularly before you can reap its health benefits. Remember, other factors such as lifestyle, overall diet, and age may determine the beneficial effect of drinking green tea.
