Green Tea Research

Natural Biology has added Green Tea to our Top Ten List because there is perhaps no other natural vitamin micro-nutrient that has as many good studies proving its usefulness in human health; however what is important is that it be used either as a green tea drink or when used as a supplement that one uses Green Tea Extract 98% with 50% ECGC - found in EVEREST Earth & Sea Formula.  

The tea plant, or camellia sinensis, has been known to have numerous health benefits for nearly five thousand years, since the legendary Chinese emperor Shen Nong infused and wrote about the plant. He wrote that the tea plant is a powerful restorative when boiled, and that it eliminates poisons from the body. There are many different ways of preparing tea: these different ways create the different forms of tea we have today: black, green, white, oolong, and pu-erh, among others. While studies have been made on the many different types of tea, green tea has long been considered the most healthy, and thus the most-often studied.

Green tea is different from other varieties of tea, in that the leaves from camellia sinensis are steamed rather than fermented in their preparation. When the leaves are fermented, it is found that a powerful compound in the tea plant, EGCG, is oxidized and lost. Green tea, on the other hand, has the highest level of EGCG of any other type of tea. EGCG, or epigallocatechin gallate, is a powerful antioxidant which is responsible for much of the health-giving qualities of green tea.

Antioxidants reduce the level of free radicals in the body, which are key to the growth of cancer cells, among other things. EGCG, in particular, has been shown to inhibit cholesterol growth as well, with studies showing that it inhibits intestinal absorption of bad cholesterol, promoting its expulsion from the body. This, in turn, leads to decreased heart disease, as high cholesterol can mean that plaque builds up in the arteries.

Aside from reducing cancer and heart disease, green tea has long been known for the mental alertness it inspires, while not producing a "high" or a "crash" the way many sources of caffeine do. It has been described as a calmer, more alert state of mind, and is largely credited to L-theanine, an amino acid found in the tea plant. In addition, a cup of green tea contains as much vitamin C as a lemon, making it a great immune system booster.

Green tea can be taken in pill form, or it can be steeped in boiling water and drunk. Green tea extract in pills is the best way to get the health benefits quickly, as they contain all the EGCG and other polyphenols in their purest form. This is great if you don't like the taste of green tea, or if you know it's good for you but don't have the time to make it every day. On the other hand, there's something to be said for the act of sitting down, calming your body, and drinking a cup or two of tea to start the day. Warm liquid is said to be stimulating to the digestive system, and the aroma can be as satisfying as the tea itself. Nevertheless, green tea extract tends to have a smaller amount of caffeine than the corresponding amount of green tea, so if you're worried about insomnia, the extract pills might be the way to go.

In addition to the health benefits described above, green tea has been shown to improve metabolism, thus aid in weight loss. Though these studies haven't been explicitly proven to be true, links have been made between the cholesterol-inhibiting properties of EGCG and the weight loss many people have experienced when they switch from coffee to green tea as their morning beverage of choice.

Green tea has been roundly hailed by nutritionists and health food experts as one of nature's cure-alls. Whether or not that's the case, green tea certainly has many health benefits and very few drawbacks, save for the small amount of caffeine it contains. If you're looking for a warm beverage to start your day, definitely consider green tea for the health benefits it will confer upon your body.
