Scientific Studies on the Health Benefits of Drinking Green Tea

For thousands of years, Asian cultures have enjoyed the benefits of drinking green tea. Over the past few decades, the western world has discovered these benefits and green tea has gained popularity as a hot or cold beverage. Whether you serve it up in a steaming mug or iced with a shot of your favorite juice for sweetness, you, too can enjoy the health and feel-good benefits of this ancient elixir.

Green tea is available in many forms including dried leaf, tea bags or powered. Roasted green tea serves up a rich, toasty flavor whether served hot or cold. Ready brewed iced green tea made with care to preserve its nutritional integrity is available at health food stores.

Benefits of green tea consumption appear to be many.

In a study conducted at Purdue University1, researchers found that EGCG, a compound in green tea, inhibits an enzyme required for cancer cell growth and can kill cultured cancer cells with no ill effect on healthy cells. Research from the Linus Pauling Institute at Oregon State University suggests that this same compound can help suppress autoimmune disease2.

Green tea may shave a few points off “bad” cholesterol readings, according to a study published in the Journal of the American Dietetic Association3.

Improved bone health and slowing of the bone thinning process could be a benefit of drinking green tea, according to a study published in The Journal of Agricultural and Food Chemistry. Researchers found that the EGCG in green tea was extremely beneficial in blocking bone thinning activity4.

According to a study published in the Journal of Periodontology which analyzed the periodontal health of 940 men found that those who regularly drank green tea had superior periodontal health over subjects that consumed less green tea5.

And a recent study at the University of Basel Switzerland found that green tea can actually help boost your brain power, especially the working memory6.

To attain full benefit, you need to make a conscious choice to drink green tea regularly, instead of sugar and chemical laden sodas or rich coffee drinks.

Yours in good health,
