1.  To Control Diabetes

  • Can Tea Help with Diabetes? Is It Beneficial? - TheDiabetesCouncil.Com

“There has been some evidence in recent years that drinking certain teas, in certain quantities, can have a beneficial effect on your health whether you have diabetes or not. For those living with diabetes, tea actually has the potential to do a lot of good. Depending on what type you drink, tea can chemically assist your body with processing and managing sugar and insulin levels and can also help people manage some of the symptoms of diabetes, including circulation problems, energy levels, blood pressure and more.”

  •  Why Drinking Tea May Help Prevent and Manage Type 2 Diabetes- Everyday Health

“A 2013 research review published in the Diabetes and Metabolism Journal outlined the potential benefits of tea when it comes to diabetes as well as obesity, which is a risk factor for diabetes. It highlighted a Japanese study that found that people who drank 6 or more cups of green tea a day were 33 percent less likely to develop type 2 diabetes than were people who drank less than a cup of green tea a week. It also reported on Taiwanese research that found that people who drank green tea regularly for more than a decade had smaller waists and a lower body fat composition than those who weren't regular consumers of green tea.

Drinking tea for diabetes is such a good idea because tea contains substances called polyphenols, which are antioxidants found in every plant. “Polyphenols help reduce oxidative stress and cause vasodilation (widening of the arteries), which decreases blood pressure, prevents clotting, and reduces cholesterol,” Dr. Steinbaum says. All of these activities reduce the risk for heart disease, which is elevated in people with diabetes. Polyphenols in green tea can also help regulate glucose in the body, helping to prevent or control diabetes.”

2. Weight Management

  •   Every Weight-Loss Tea You Need to Start Losing Weight- Reader’s digest

Oolong teas are partially oxidized (black teas, for instance, are fully oxidized), lending a smooth, but bold taste to the brew. Happily, they also help boost your body’s ability to metabolize fats, reports a 2009 study from Chinese researchers. When obese and overweight participants consumed oolong for six weeks about two-thirds lost more than 2.2 pounds and 12 percent belly fat. Bonus: They ended the study with healthier cholesterol and triglyceride scores, all adding up to a stronger ticker.

  • Facts About Oolong Tea and Weight Loss- LIVESTRONG.COM

“The polyphenols in oolong tea are at least partially responsible for any potential weight-loss benefits. An animal study published in The Journal of Nutrition in September 2014 reported that the polyphenols from oolong, green or black tea helped increase weight loss and fat loss even in the presence of a high-sugar diet. One type of these polyphenols, called catechins, may help keep your metabolism from slowing down as you lose weight, according to a review article published in The American Journal of Clinical Nutrition in October 2013, making it slightly easier to keep losing weight and maintain that weight loss.

The caffeine in oolong tea is likely just as important for increasing weight loss as the catechin content. A study published in The American Journal of Clinical Nutrition in November 2009 found that tea containing both catechins and caffeine resulted in more weight loss than consuming either catechins or caffeine alone. These two substances may work together to help increase your metabolism and the amount of fat you burn while helping to maintain lean body mass, according to a review article published in Physiology & Behavior in April 2010, so decaffeinated versions of oolong tea may not be as helpful for weight loss as regular oolong tea.”

3. To help fighting harmful free radicals

  • Drink your way to health as the antioxidants in tea cut free radicals- SCIENTISTLIVE

“A major proportion of premature deaths in developed countries is due to coronary heart disease and cancer. Free radicals, produced endogenously as a by-product of aerobic metabolism, are implicated in the pathogenesis of these diseases because they have considerable chemical reactivity with biological molecules. Such damage to cellular lipids and DNA increases the risk of developing heart disease and cancer respectively. In addition, there is now considerable evidence that inadequate dietary intakes of antioxidant micronutrients, such as flavonoids and phenolic compounds, which prevent free radical-mediated damage in vivo, contribute to these disorders.”

“Tea might provide protection from ultraviolet rays. We know it’s important to limit exposure to UV rays, and we all know what it’s like to feel the burn. The good news is that green tea may act as a back-up sunscreen. Tea can help the body recover from radiation. One study found that tea helped protect against cellular degeneration upon exposure to radiation, while another found that tea can help skin bounce back post exposure.”

“Too much sun can be damaging to the skin and cause early signs of aging. Studies have shown that drinking green tea may actually help reduce your risk of skin cancer (although you still have to wear SPF 30 daily, of course). Renee Snyder, M.D., board-certified dermatologist and co-founder of cosmetics brand W3LL PEOPLE, says the catechins (antioxidants that may prevent cell damage) in green tea can decrease inflammation associated with aging, as well as protect against sunburns and potentially long-term UV damage.”

5.  To manage stress

  • A cup of tea really can help reduce stress at times of crisis, claim scientists- The Telegraph

“The study, by psychologist Dr Malcolm Cross at City University London, confirms what millions of tea-lovers have long believed – that if you are upset or anxious, it pays to make a brew. The findings reveal that even a single cup of tea can significantly reduce anxiety levels after suffering a stressful experience – and in some cases, make people calmer than they were before. The experiment at the centre of the study, which placed volunteers in a stressful scenario, showed a 25 per cent increase in anxiety for those that did not receive tea immediately after the stress-inducing test. Conversely, those who were given tea actually demonstrated a four per cent reduction in stress.”

  •  The Therapeutics of Tea: Why L-Theanine Can Help Stop Stress- HUFFPOST

“Recent studies are indicating an interesting link between stress reduction and a common household item: tea. Tea has long been known as a rich source of flavonoid antioxidants, but its lesser-known therapeutic property is its source of L-theanine, a non-protein amino acid and a natural constituent in tea. Research is now showing the potential connection between L-theanine and the reduction of psychological and physical stress, even noting a decrease in ADHD symptoms in school-aged boys.”

6 . To keep your mouth fresh

  • Drinking Tea for Good Oral Health- Cassell Dentistry

“Drinking green tea every day can help fight off signs of gum disease. In a survey of about 1,000 men conducted in Japan, men who drank green tea every day showed improvements in both gum recession and bleeding gums, both of which are signs of gingivitis. A study in Egypt also found that green tea can reduce gum bleeding. Tea has anti-inflammatory properties, and it is possible that the antioxidants present in it are also benefiting the gums.

Cavities and tooth decay can also be prevented with green tea. The drink naturally lowers the acidity of your mouth and can help eliminate oral bacteria. Black tea also kills oral bacteria. In fact, the catechins and theaflavins (two types of polyphenols) found in black tea inhibit the growth of bacteria in your mouth and can also fight off bad breath.

Drinking tea can also help in preventing oral cancer. As we mentioned before, tea is rich in antioxidants, which can help protect against cellular damage and lowers the risk of developing cancer. In patients who have already developed a precancerous condition called oral leukoplakia, drinking tea has been found to help combat the disease. Tea may help reverse the damage to DNA that causes cancer to develop.”

  •  Drinking Tea – Powerful Against Dental Enemies- Medical Website

“Researchers on nutrition science found out that melted black tea particles are effective combatants against streptococcus mutans, the bacteria that is specifically identified with gum and tooth maladies. Even green tea has its benefits to dental and oral care. The studies show that the natural chemicals found in green tea have a neutralising effect on the sulfur compounds coming from the food debris inside the mouth. The sulfur compounds are one of the causes of bad breath. Thus, it goes without saying that green tea helps in curbing off bad breath from your mouth.”

7. To prevent cancer

  • Tea and Cancer Prevention-NATIONAL CANCER INSTITUDE

“Among their many biological activities, the predominant polyphenols in green tea―EGCG, EGC, ECG, and EC―and the theaflavins and thearubigins in black teas have antioxidant activity. These chemicals, especially EGCG and ECG, have substantial free radical scavenging activity and may protect cells from DNA damage caused by reactive oxygen species. Tea polyphenols have also been shown to inhibit tumor cell proliferation and induce apoptosis in laboratory and animal studies). In other laboratory and animal studies, tea catechins have been shown to inhibit angiogenesis and tumor cell invasiveness. In addition, tea polyphenols may protect against damage caused by ultraviolet (UV) B radiation, and they may modulate immune system function. Furthermore, green teas have been shown to activate detoxification enzymes, such as glutathione S-transferase and quinone reductase, that may help protect against tumor development. Although many of the potential beneficial effects of tea have been attributed to the strong antioxidant activity of tea polyphenols, the precise mechanism by which tea might help prevent cancer has not been established. “

  • 13 Reasons Tea Is Good for You-Time

“The antioxidants in tea might help protect against a boatload of cancers, including breast, colon, colorectal, skin, lung, esophagus, stomach, small intestine, pancreas, liver, ovarian, prostate and oral cancers. But don’t rely solely on tea to keep a healthy body — tea is not a miracle cure, after all. While more studies than not suggest that tea has cancer-fighting benefits, the current research is mixed.”

  •  10 Wonderful Benefits of Oolong Tea-Organic facts

“It is a well-known fact that tea drinkers have a lower risk of getting skin cancer. Moreover, the polyphenolic compound in oolong tea promotes apoptosis in case of cancerous cell growth in the stomach. This polyphenolic extract also acts as a chemo-preventive instrument against the development  of other cancers as well. The compounds stifle the activation of carcinogenic cells, prevent the formation of N-nitroso compounds, and trap genotoxic agents before they can become effective.”

8. To reduce the risk of cardiovascular and degenerative diseases

  • Tea can reduce another risk of heart attack- Dailymail

“Researchers believe the protection in tea may be coming from flavonoids - antioxidants that are found naturally in various foods, including fruit and vegetables such as apples, onions and broccoli. Although some healthy effects of antioxidants are known, this is the first-time researchers have found that flavonoids protect after a heart attack.”

GABA - What is GABA? What are the potential benefits?

Unique health benefits of organic GABA oolong tea - T CHING

GABA oolong tea has all of these qualities, but it is also one of the richest food sources available for natural GABA (Gamma-aminobutyric acid) – an important amino acid that functions as a neurotransmitter in the central nervous system.

GABA, as a health supplement, is being used by many pharmaceutical companies these days for a variety of health disorders as well as by some commercial food and drink companies as a popular additive.  Some of the health benefits being promoted for GABA supplements include:
–  Reduces high blood pressure
–  Relieves stress and anxiety
–  Deceases hypertension
–  Increases mental alertness
–  Increases memory retention
–  Increases energy levels and exercise endurance
–  Promotes weight loss
–  Acts as an antibacterial
–  Alleviates alcohol withdrawal symptoms
–  Prevents and cures hangovers
–  Offers anti-aging properties
–  Improves sleep
–  Improves skin elasticity and de-emphasizes wrinkles
–  Increases sexual performance
–  Aids in overcoming depression, anxiety, and other mental disorders
The Japanese originally “discovered” GABA tea and have long recognized the health benefits of it as a key source of GABA.  In fact, it has almost become a staple part of the Japanese diet.
GABA tea is made naturally by exposing the tea leaves to nitrogen – instead of oxygen – during the oxidation process.  The result is a heavily oxidized oolong tea (approximately 70-80%) that has a pleasant, slightly sweet taste, almost more like a black tea flavor than a regular oolong.

GABA Tea and the Hype around its Health Benefits - World Tea News:

GABA has been credited with contributing to lower stress levels, improving sleep, and reducing depression and anxiety.

What does it have to do with tea?
Some teas, such as oolong, have high levels of GABA. Some processors are creating “GABA tea” by oxidizing tea in a high-nitrogen, oxygen-free environment instead of oxygen during oxidation. This process was introduced in Japan in the 1980s when Dr. Tsushida Tojiro discovered that anaerobic conditions encourage the conversion of glutamate to GABA. That country sells many GABA-enriched foods and beverages like rice, soy milk and cookies.

Beverage Science: Finding GABA in Tea - Fresh Cup Magazine:

The good news is that GABA occurs naturally in Camellia sinensis. And, thanks to discoveries by Japanese scientists, there’s a processing method to significantly increase GABA in teas. Credit is given to Dr. Tsushida Tojiro for discovering, in 1987, that when freshly picked tea leaves are exposed to anaerobic conditions (meaning without oxygen) the glutamic acid in the leaves is converted into GABA and processing the leaves in a nitrogen-rich atmosphere results in significantly higher concentrations of GABA. Further study revealed increased levels of glutamic acid in tea leaves that were shaded for ten to fifteen days before picking which, in turn, leads to even higher concentrations of GABA.
Today true GABA tea, available as green and oolong, is made in Japan and Taiwan. The freshly picked leaves are placed in stainless steel vacuum drums. Oxygen is removed and replaced with nitrogen. For the highest GABA concentration the leaves remain in the container for eight to ten hours, heated above 104 degrees Fahrenheit. The container is then shaken continuously for up to three hours under aerobic conditions (oxygen is introduced). These steps might be repeated several times prior to steaming or rolling which is followed by a final drying of the tea leaves. As with all tea production, other methods certainly do exist.
