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...).
Research shows that people who regularly drink green tea do not fall victim to common bacterial and viral infections as easily as those who do not add it to their diet. It boosts the immune system. The catechins, present in green tea, prevent bacteria and viruses from attaching themselves to cell walls in order to infect them. These catechins also counter the toxins released by microbes. This antimicrobial property also protects you from bad breath, dysentery, diarrhea, tooth decay, indigestion, flu, cough and cold, and colitis, all of which are caused by the microbial and fungal action.
A well-known compound found in green tea is called EGCG (which stands for epigallocatechin-3-gallate). EGCG is associated with enhanced metabolic activities that may prevent weight gain or assist with weight maintenance. Some of the ways that EGCG seems to work is by boosting thermogenesis (the body producing heat by using energy) and suppressing appetite, although not every study has found evidence that these effects are substantial.

But ConsumerLab.com’s testing has found that even if lead is found in the leaves used in green tea bags, it doesn’t appear to be absorbed into the water. Cooperman says his team was concerned about lead content in matcha, because people consume the ground green tea leaves directly rather than in bags. However, their testing showed that among the six popular matcha brands they tested—DoMatcha, Encha Organic Matcha, Rishi Teahouse Matcha, Teavana Imperial Matcha, Kirkland Signature Green Tea and The Republic of Tea Double Green Matcha Tea—the powders were not contaminated by lead or other metals, and also did not contain pesticides. As of now, Cooperman says he doesn’t believe lead exposure is a risk in the matcha currently sold in the United States.
Matcha is best enjoyed as soon as possible after its production. Since matcha is a ground tea, any exposure to oxygen will immediately start to degrade the color and flavor of tea. If stored sealed in a cool, dark place it can stay fresh for several weeks and up to a few months (unlike dried tea leaves which can last for up to a year or two). To ensure you’re getting a fresh matcha worth sipping, buy it from a reputable company that can tell you when and how the tea was processed and packaged. Ask your tea purveyor for directions on how to brew the best cup of that particular variety of matcha.
Green tea is processed using either artisanal or modern methods. Sun-drying, basket or charcoal firing, or pan-firing are common artisanal methods. Oven-drying, tumbling, or steaming are common modern methods.[32] Processed green teas, known as aracha, are stored under low humidity refrigeration in 30- or 60-kg paper bags at 0–5 °C (32–41 °F). This aracha has yet to be refined at this stage, with a final firing taking place before blending, selection and packaging take place. The leaves in this state will be re-fired throughout the year as they are needed, giving the green teas a longer shelf-life and better flavor. The first flush tea of May will readily store in this fashion until the next year's harvest. After this re-drying process, each crude tea will be sifted and graded according to size. Finally, each lot will be blended according to the blending order by the tasters and packed for sale.[33]

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.

It’s important to note that I was not interested in, hoping for, or expecting any drastic changes to my appearance. I already lead a pretty healthy lifestyle: I drink 80 oz. of water a day, I work out at least 4-5 days a week, and I do my best to eat lean protein and lots of fruits and veggies. Like I said, I love food, but I’m usually good at keeping my cravings in moderation. I did not have a “goal weight,” and there were no numbers I was hoping to change (blood pressure, weight, heart rate, etc.). I cannot stress this enough: Acknowledge your own body, its needs, and its goals before you try any new regimen. A detox should fit into your life — you should not expect it to change your body overnight.
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, however, is considered to have originated in China. It is said that even today the word “tea” in China refers only to green tea, not to the general category of tea as it does in the West. China’s Yunnan province is considered to be the original home of the Camellia sinensis plant species. In fact, 260 of the world’s 380+ varieties of tea can be found in Yunnan.
