Several population-based clinical studies have shown that both green and black teas may help protect against cancer. Early clinical studies suggest that the polyphenols in tea, especially green tea, may play an important role in the prevention of cancer. Researchers also believe that polyphenols help kill cancerous cells and stop them from growing.
Most detox teas contain caffeine, probably because this stimulant may suppress appetite, trigger your digestive system to let go of waste, and help you shed water weight. A caffeine-induced energy boost may also lead to working out a little longer or harder than usual. However, too much caffeine can also be risky (see above) and interfere with getting enough sleep–and catching too few zzzs may ultimately undo the tea's weight-loss effects. In fact, too little shuteye has been shown to trigger excessive eating and weight gain and even slow metabolism, which can make it easier to gain weight even if you don't eat extra calories. A good rule of thumb, regardless of where your caffeine is coming from, is to nix it at least six hours before bed. And if you're trying to shed pounds, commit to making adequate sleep a top priority.
What I will tell you is that there are a LOT of options for these fitness teas. I did a lot of research before purchasing one, so my best advice to you is to make yourself a list of available options (see below), determine what you hope to gain from the experience (see even further below), and then research the specific ingredients for yourself. Here’s the moral of the story: They’re all very similar, but it’s important to be aware of what you are personally putting in your own body. Disclaimer: What works for one may work differently for another — so take your research seriously.
A stone mill consists of two granite parts, with a slight opening in the middle called "Fukumi." The tea is funneled in from the top, filling in this small space, and pushed out gradually. Though each stone mill can only grind up to 30-40g of Matcha per hour (that's approximately one tin), only these mills made of granite are able to preserve the color, flavor, and nutritional components of Matcha.
Matcha, the focal point of the Japanese Tea Ceremony, is a fine powder made by grinding green tea leaves. Only the finest, young, shade-grown gyokuro tea leaves are used to create matcha. The leaves are plucked and laid out flat to dry. Veins are removed and the leaves, now called tencha, are carefully ground in granite mills until they become the precious powder. Easy preparation is achieved by placing 1 teaspoon of matcha per cup (or to taste) in a cup, adding a few drops of hot water (160-180F) and stirring with a spoon until a paste forms. Add the rest of the water and stir.
Matcha tea works wonderfully well in providing a calming effect on the body. L-theanine, a unique amino acid present in this green tea, possesses anti-anxiolytic properties, which assists in boosting alpha waves in the brain. These alpha waves enhance mood, encourage relaxation, induce a profound feeling of mental clarity, and help achieve an alert state of mind.
Rooibos tea can be useful for small children who suffer from colic or stomach pain. You may add some sweetened milk to farm direct red rooibos tea to improve the flavor and make it more palatable. This is actually why rooibos tea is a well-known health aid. Many South African women claimed that this plant was very soothing for their colicky infant.
"Drink tea if you enjoy it, in moderation, and not because you're taking it as a medicine," says Dr. Sesso. Stirring in a little sugar is fine, but if you add a few heaping teaspoons of sugar, you're probably canceling out tea's possible benefits, he notes. And beware of the sugar found in many bottled teas, some of which contain as much as nine teaspoons of sugar per serving—almost as much as colas and other soft drinks. Check bottled tea labels and choose only pure, unadulterated tea—or save money and brew your own at home.
Studies on green tea’s impact on cancer have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some clues that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's web site says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer."
You’ve probably heard a lot about the health benefits of drinking tea, especially the benefits of green tea, considered by many to be the ultimate “anti-aging beverage.” In Okinawa, Japan — one of the world’s “Blue Zones” that’s associated with longevity —drinking green tea daily is considered “essential.” (1) A popular practice is sipping on a combination of steeped green tea leaves, jasmine flowers and a bit of turmeric throughout the day.
If not taken with sugar, the alkaline nature of green tea helps reduce the blood glucose level. Moreover, the antioxidant and astringent qualities of green tea ensure good health and better functioning of the pancreas. Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
Shade grown: All matcha is made from shade-grown tea leaves—a labor-intensive process where tea bushes are protected from the sun and light is filtered to the bushes in a very controlled manor. Shading boosts the chlorophyll production in the plant, giving the leaves a rich green color. The lack of sun reduces the plant’s photosynthesis of the leaves, which in turn alters the naturally occurring levels of caffeine, flavanols, sugars, antioxidants, and theanine. By controlling the sun exposure, tea producers can significantly alter the chemical make-up and flavor of the final tea leaves.
Matcha tea rich in EGCG helps fight various bacterial, viral, and fungal infections. According to a research study, EGCG binds to the lipid membrane and exerts inhibitory action against the growth of various human pathogens. These include influenza A virus, hepatitis B, and C virus, herpes virus, adenovirus Staphylococcus aureus bacteria, and Candida albicans yeast.
• One Chinese study found that men who drank more than three cups of tea a day reduced their risk of prostate cancer by 70 percent. In another study funded by the National Institute of Health, 79 men with prostate cancer were told to either drink 6 cups of green tea a day or 6 cups of water. After 3 to 8 weeks, the levels of prostate-specific antigen, a protein that may indicate cancer, were lower in the men who drank green tea than those who drank water. An indicator of inflammation, nuclear factor-kappaB, linked to cancer growth, was also lower in the men who drank the green tea.
