Apart from causing premature aging, free radicals are also responsible for causing certain types of cancer. The catechins present in green tea neutralize these free radicals, prevent the formation of carcinogens like nitrosamines and reduce the risk of cancer for people who regularly consume it. Green tea is now being clinically used and prescribed as a home remedy to aid in the prevention of cancer, particularly for those patients at high risk for cancer in the colon, rectum, pancreas, and intestines.
The leaves are used to make a herbal tea that is called by the names: rooibos, bush tea (especially in Southern Africa), or redbush tea (predominantly in Great Britain). The tea has been popular in Southern Africa for generations, but is now consumed in many countries worldwide. It is sometimes spelled rooibosch in accordance with the original Dutch. The tea has a taste and color somewhat similar to hibiscus tea, or an earthy flavor like yerba mate.
"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.

Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.
Several large, population-based studies show that people who regularly drink black or green tea may be less likely to have heart attacks and strokes. However, people who drink tea tend to be different from people who don't drink tea. "We can't quite disentangle whether it's their tea drinking or something else those people are doing that lowers their risk of cardiovascular disease," explains Dr. Sesso. "Some experts believe that tea may have cardiovascular benefits, but it's not considered a slam-dunk proposition."
Those magical catechins also have tons of potential in helping people with heart issues. “Catechins present in green tea have the ability to prevent atherosclerosis, hypertension, endothelial dysfunction, ischemic heart diseases, cardiomyopathy, cardiac hypertrophy and congestive heart failure by decreasing oxidative stress, preventing inflammatory events, reducing platelet aggregation and halting the proliferation of vascular smooth muscle cells,” explains the author of the study, published in the Chinese Journal of Natural Medicines.
Our green tea is passed through a steaming treatment before rolling. Steaming applies light heat to the leaves to help halt the oxidation process before the leaves are rolled into shape. Steaming also helps expose the fresh, grassy flavor of the leaf. Green tea leaves are not allowed to oxidize after rolling, which is why they remain light color and flavor.
Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects. In 2011, a panel of scientists published a report on the claims for health effects at the request of the European Commission: in general they found that the claims made for green tea were not supported by sufficient scientific evidence. Although green tea may enhance mental alertness due to its caffeine content, there is only weak, inconclusive evidence that regular consumption of green tea affects the risk of cancer or cardiovascular diseases, and there is no evidence that it benefits weight loss.
Matcha is a type of green tea made by taking young tea leaves and grinding them into a bright green powder. The powder is then whisked with hot water. This is different from regular green tea, where the leaves are infused in water, then removed. Drinking brewed green tea “is a bit like boiling spinach, throwing away the spinach and just drinking the water,” says Louise Cheadle, co-author of The Book of Matcha and co-owner of the tea company teapigs. “You will get some of the nutrients, but you’re throwing away the best bit.” With matcha, you’re drinking the whole tea leaves.
One-1/2 teaspoon serving of matcha, no more than once daily, is certainly a valuable addition to any diet, says Zeitlin. Like with another substance currently having a moment, turmeric, you can get your dose by eating or drinking it, though Zeitlin says drinking it as a tea, how it was initially intended, provides all the benefits without the added calories.
Because matcha is prone to clumping (that’s why you’ll see instructions to sift it before whisking in the water or milk), you’ll want to take the same precaution in your baking experiments: Saffitz suggests combining the matcha with other dry ingredients like sugar or flour to avoid bitter lumps in your dough or batter. And use it sparingly, she suggests: Even a few teaspoons can create an intense flavor (and color).
It’s become such a fashionable beverage that, last summer, the New York Post ran a story about how Victoria’s Secret models were flocking to Cha Cha Matcha, a hipster spot fluent in the preparation of various matcha-based miracle potions. A search for where to get “matcha” in New York, New York on Yelp yielded some 1400 plus results. Even mass market coffee purveyors like Starbucks have made matcha their mantra, with a vast range of offerings to cash in on the craze.
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.
Day 14: At halfway through my detox, I finally officially figured out what works for me and my body. The plan: my standard first-thing-in-morning cup of coffee, then an iced version of the tea to drink with me throughout the day. I sip it all day long, and it’s both refreshing and hydrating. I can very honestly say I feel AWESOME. I’m having no kinds of digestive problems, I feel lighter while running at the gym, and my stomach is significantly less bloated and more toned.
Caffeine: Everyone knows that caffeine is an external stimulant and raises blood pressure, and is actually toxic in nature (it may be fatal for some animals). Caffeine is also addictive and can have adverse effects on the liver and internal organs over the course of many years. That being said, it is the component of tea which makes it energizing and refreshing, which is why people are willing to risk it.
According to Record of Gaya cited in Memorabilia of the Three Kingdoms, the legendary queen Heo Hwang-ok, a princess of the Ayodhya married to King Suro of Gaya, brought the tea plant from India and planted it in Baegwolsan, a mountain in current Changwon.:3 However, it is a widely held view that systematic planting of tea bushes began with the introduction of Chinese tea culture by the Buddhist monks around the 4th century. Amongst some of the earliest Buddhist temples in Korea, Bulgapsa (founded in 384, in Yeonggwang), Bulhoesa (founded in 384, in Naju) and Hwaeomsa (founded in Gurye, in 544) claim to be the birthplace of Korean tea culture. Green tea was commonly offered to Buddha, as well as to the spirits of deceased ancestors. Tea culture continued to prosper during the Goryeo Dynasty, with the tea offering being a part of the biggest national ceremonies and tea towns were formed around temples. Seon-Buddhist manners of ceremony prevailed. During the Joseon Dynasty, however, Korean tea culture underwent secularization, along with the Korean culture itself. Korean ancestral rite jesa, also referred to as charye (차례; 茶禮, "tea rite"), has its origin in darye (다례; 茶禮, "tea rite"), the practice of offering tea as simple ancestral rites by the royal family and the aristocracy in Joseon.
So-called "detox" teas have been popular for years, primarily among people who frequent health-food stores, or consult with alternative practitioners. These days, though, they've become big business, and a handful of celebrities are touting their weight-loss benefits on social media. In a way, detox teas have become the liquid version of waist trainers–the before and after results are often dramatic, and their celeb backing generates buzz, but you may be wondering: Do they really work, and are they safe? Before you plunk down your hard-earned money and start sipping, here are five things you should know.
In 2009, King’s College researchers found that epicatechin may protect brain cells through mechanisms unrelated to its antioxidant ability, as epicatechin is one of the few flavonoids that can cross the blood-brain barrier. The King’s College researchers reported that somehow epicatechin protects brain cells from the negative effects of beta-amyloid plaques, although the exact mechanism of how this works is still not entirely know.

Tea plants that are specifically grown and used to make matcha are also typically shaded for two weeks to increase chlorophyll levels before the leaves are picked, further boosting concentration of healthy compounds. Matcha green tea tends to be more expensive than buying tea leaves for steeping, but a little goes a long way. Matcha is usually available in powder form and is a good choice for adding green tea’s taste and the benefits of green tea to recipes like smoothies, baked goods or ice cream.
Steeping, or brewing, is the process of making tea from leaves and hot water, generally using 2 grams (0.071 oz) of tea per 100 millilitres (3.5 imp fl oz; 3.4 US fl oz) of water (H2O) or about 1 teaspoon of green tea per 150 ml cup. Steeping temperatures range from 61 °C (142 °F) to 87 °C (189 °F) and steeping times from 30 seconds to three minutes.
We’re wary of any trend that involves detoxing with just a drink. By now, we’re all pretty aware that liquid diets can’t sustain our active bodies for very long, and most of the drinks celebrities swear by have little actual detoxifying effects. But a teatox, or tea detox or tea cleanse, is a gentler approach to the whole idea, namely because it involves adding a few herbal cups to your existing, healthy diet—instead of replacing meals entirely.
In 2004, scientists at the University of Newcastle studied the effects of black and green tea on Alzheimer’s disease. In laboratory studies, both teas prevented the breakdown of acetylcholine, the neurotransmitter strongly linked with memory. The teas also inhibited enzymes known as BuChE and beta-secretase. These enzymes are found in protein deposits found in the brain of Alzheimer’s patients. (7)
Green tea is a longtime treasure of China and Japan that is gaining popularity in America. It’s easy to understand why: the best green tea leaves are heated or steamed right after harvest, preserving their all-natural flavor and resulting in a nourishing beverage containing antioxidants. With about half the caffeine of black tea, you get the health benefits of green tea in every gentle cup. You can buy green teas in either loose-leaf or green tea bags.
I LOVE this matcha. I've tried the real Japanese matcha before (it was quite expensive) so I know the basic qualities of matcha powder. Let me tell you, this matcha is really good. It smells good with a vibrant green color as a matcha should be, and tastes good! Also, the bonus ebook is an interesting and helpful source for new recipes (I've never thought of putting matcha into pizza as a spice...).
