Green Tea Effects over Telomeres and Aging

Is it true Green Tea helps to slow down aging and extend life?

Many studies suggest that is true. A study in Hong Kong suggets people who drink green tea regularly may be “younger” than those who don’t drink green tea or consume only small amounts. Many studies suggest that higher levels of Green Tea consumption reduce the risk of various diseases. And a fascinating study explains why.

The key of the study is the strong effects of Green Tea over “telomeres.”

Telomeres are an essential part of human cells that affect how our cells age.

Telomeres are an essential part of human cells that affect how our cells age. Telomeres are the caps at the end of each strand of DNA that protect our “chromosomes”, like the plastic tips at the end of shoelaces. A chromosome is an organized package of DNA found in the nucleus of animal and plant cells. Without the plastic tips, shoelaces become frayed until they can no longer do their job. Without telomeres, DNA strands become damaged.

Here’s what telomeres look like:telomeres

Telomeres prevent chromosomes from fusing with one another or undesirable changes that could lead to cancer and other serious diseases.

As we age, telomeres get shorter and shorter, and finally, telomeres disappear. Some experts have suggested the length of telomeres may be a marker for biological aging, as opposed to our chronological aging.

Then, what damages telomeres?

Studies have suggested telomeres are highly susceptible to oxidative stress. Powerful antioxidants from Green Tea help to protect telomeres and consequently, slow down aging.

"The researchers reported telomere length was associated with the amount of tea they drank."

In the above mentioned study, researchers looked at telomere lengths of 2,000 men and women who are over the age of 65. The researchers reported telomere length was associated with the amount of tea they drank. The people who drank more than 3 cups daily had longer telomeres than the people who drank less than a cup of tea daily.

The study reported the average difference in telomere length corresponded to approximately a difference of five years of life. It also concluded the antioxidative properties of tea and its constituent nutrients may protect telomeres from oxidtive damage in the normal aging process.

"The positive changes of lifestyle may result in longer telomeres."

Even better, telomeres are also known to regenarate with healthy lifestyle changes. A controlled trial showed any intervention might lengthen telomeres over time, which means we can “turn our cell’s clock back”. The positive changes of diet incorporated with Green Tea, exercise, stress management and social support may result in longer telomeres.

One more cup of Edible Green Sencha Powder or Matcha daily would be a great new habit. When you drink more than a cup a day, it works better for you if you space at least a few hours apart, as each cup replenishes its powerful antioxidants in your system.
