The function of tea and natural, bioactive compounds in tea, as elements in a healthy lifestyle is best explained by the first line in Kakuzo Okakura’s 1906 philosophical treatise on tea, The Book of Tea. Okakura sums up the historical and ancient belief in tea as more than just a pleasing beverage by writing, “Tea began as a medicine and grew into a beverage...”
Scientific research confirms what Asians believed for centuries – that green and black tea contains powerful natural antioxidants which can protect regular tea drinkers from many degenerative diseases.
The main degenerative diseases of concern today are heart disease, high blood pressure stroke, cancer and diabetes. Studies have shown that the antioxidant activity of flavonoids in green and black tea reduces the risk of many degenerative diseases and help maintain good oral heath.
Fresh Organic Tea inhibits fat absorption and helps glucose regulation
A study reported on in the American Journal of Clinical Nutrition, found that fresh tea extract resulted in a significant increase in energy expenditure (a metabolism 'boost').The researchers also concluded that that over a 24-hour period, tea extract increases the metabolic rate by 4%. These effects are probably due to the high concentrations of catechin polyphenols found in fresh organic tea. These work to help intensify levels of fat oxidation and thermogenesis (the rate at which your body burns calories). Experts tell us that the catechins in fresh organic tea help to inhibit the movement of glucose into fat cells. Fresh organic tea may also act as a glucose regulator. It helps to slow the rise in blood sugar after a meal. This prevents high insulin spikes (lots of insulin promotes fat storage) and the subsequent fat storage.
Fresh Organic Tea may help reduce appetite
Scientists at the University of Chicago found that fresh tea caused rats to lose up to 21 percent of their body weight. Rats injected with a fresh green tea extract lost their appetites and consumed up to 60 percent less food after seven days of daily injections. This may have something to do with the blood sugar regulating effects of green tea. Green tea can help you save calories on your morning brew.
Fresh Organic Tea and Heart disease
Regular consumption of fresh organic tea, has been shown to reduce oxidation of fat. Studies suggest that green and black tea are equally effective in this respect.
High concentrations catechins in fresh green tea, theaflavins and thearubigins in fresh black tea were shown to have the ability of inhibit lipid oxidation and plaque formation (which can lead to heart disease), whilst reducing cholesterol. Regular consumption of fresh tea has also been associated with reduced blood clotting. Blood clotting increases the risk of coronary thrombosis.
Tea extracts and tea polyphenols can inhibit the platelet aggregation to a certain degree, thereby reducing the risk of thrombosis. Both Green and Black Tea also improve endothelial function (vasoconstriction and vasodilation - the control of blood pressure, atherosclerosis, formation of new blood vessels -angiogenesis).
Fresh Organic Tea and Cancer
Numerous in vitro and in vivo studies have revealed that polyphenols in fresh green and black tea can directly react and neutralize chemical carcinogens thereby reducing the risk of cancer. It has also been shown that tea increases the activity of detoxifying enzymes which are naturally found in the human body.
The anticarcinogenic potential of tea is based on the ability of tea flavonoids to interact with the active carcinogens and make them inactive. In vitro and in vivo research indicates that tea and tea polyphenols inhibit initiation and later stages in the development of carcinogens. Regular consumption of tea – especially fresh tea – decreases the growth rate of tumors whilst preventing the formation of large tumors.
Fresh Organic Tea and Diabetes
In Type-1 diabetes the pancreas does not produce the required amount of insulin to required amount of insulin to regulate blood glucose. In Type 2 diabetes liver and muscle cells cannot utilize the insulin produced to regulate blood glucose.
Some plant extracts contains substances, which could mimic the action of insulin and help in managing Type 2 or non-insulin dependant diabetes. The flavonol, myricetin, which is present in green and black tea is found to be able to mimic insulin activity.
The enzyme alpha-amylase catalyses the conversion of starch in food to glucose in the digestive process. Glucose in the digestive tract is easily absorbed into the blood stream while starch is not absorbed. Polyphenols in tea inhibit alpha-amylase activity and could contribute to reducing blood glucose. Research suggests that tea consumption can be highly beneficial for diabetics.
Fresh Organic Tea and Ageing
Antioxidants in fresh tea are known for their ability to reduce oxidative stress. Diseases of old age are thought to be the result of attack by Free Radicals. Tea polyphenols inhibit the action of Free Radicals and can contribute to better quality of life for the elderly and also possibly longevity.
Fresh Organic Tea and Oral Health
Fresh Tea contains fluoride therefore tea drinking makes a significant contribution to the daily fluoride intake and to the reduction of tooth decay. It has been found that in addition to fluoride, the polyphenols in tea also act to reduce tooth decay. Recent studies have revealed that tea inhibits the growth of other harmful microorganisms in the mouth.
In addition to these and other function benefits that are likely in fresh tea, scientists identified a compound called L-theanine in tea. L-theanine is said to be responsible for promoting a feeling of relaxation, whilst maintaining mental alertness. 50mg of L-theanine (contained in two to three cups of tea) can naturally stimulate the brain and bring on refreshed and relaxed sensation.
How much Tea
Natural plant derived foods generally contain antioxidants although the antioxidants in fresh green and black tea are much greater than levels found in fruits and vegetables. As a general rule, two cups of tea are equivalent in antioxidant capacity, to five portions of fruit or vegetables.
Researchers are generally agreed that 5-10 cups of tea are recommended although no adverse effects have been noted from consumption of more than this number. Care should be exercised though by infants, young children at risk of type 1 diabetes, pregnant women, patients on psychoactive drugs or with sensitivity to caffeine, and tea drinkers whose diets are nutritionally not balanced.
Revelations on the therapeutic qualities of tea have been overwhelming. According to research, there are not many of mankind’s ailments that are untouched by its therapeutic qualities. No other natural or synthetic substance comes even close to tea in terms of benefits across such a multitude of fronts. A panacea it may not be, but there is no denying that in this health conscious era, science is excited by what tea has to offer and has placed it under their microscopes like none other before.
Tea and your health.
Decaffeinating your Tea at home
Decaffeinated teas are commercially available. However, the process involves chemicals which may leave traces after the processing. So organic Teas cannot be decaffeinated.
How are coffee, tea and colas decaffeinated?
The process of decaffeinating tea using chemicals not only removes the caffeine content but also some of the health promoting nutrients and polyphenols found in the tea leaves.
There is an alternate way of making a decaffeinated tea right in your home. How about that? A caffeine free tea which you prepare yourself. The process uses no chemicals and can remove up to 80% of the caffeine from the tea leaves. How much caffeine will be left will depend on the source (black tea, oolong tea, green tea).
Caffeine is very water soluble compared to the antioxidants (polyphenols) in tea. It means that caffeine easily combines with water when it makes contact with it. The higher the water temperature, the faster the caffeine combines with it. Here's what you'll do to make your tea almost caffeine free, approximately 80% caffeine free.
* Boil some water
* Place your tea leaves in a separate container
* Pour some boiling water in the container where you placed your tea leaves.
* Allow to steep for 30-45 seconds.
* Discard that water which now contains a lot of caffeine from the tea leaves.
* Boil the water again then pour it in the container and allow to steeping for 2-5 minutes
* You can now drink and enjoy your home made decaffeinated tea.
You can drink more cups in a day without worrying of the side effects that caffeine may bring to your health.
