Being a green tea, matcha does contain caffeine and in higher levels than other green teas. Because the entire leaf is used, matcha tea can contain nearly as much caffeine as a cup of coffee. However, caffeine release is believed to be slower because you are drinking the entire leaf. This slower release of caffeine reduces “caffeine jitters” that coffee or other teas can cause.
In Canada, green tea is defined as a dry-based mixture and the sale of it is regulated by the Canadian Food Inspection Agency (CFIA). It is one of the foods for which a standard of identity is specified according to the Food and Drug Regulations. It should contain not less than 33% water-soluble extractive (determined by official method FO-37 which is the determination of water-soluble extractive in tea) and the total ash should between 4% to 7%.
Japanese green teas have a thin, needle-like shape and a rich, dark green color. Unlike Chinese teas, most Japanese teas are produced by steaming rather than pan firing. This produces their characteristic color, and creates a sweeter, more grassy flavor. A mechanical rolling/drying process then dries the tea leaves into their final shape. The liquor of steamed Japanese tea tends to be cloudy due to the higher quantity of dissolved solids.
• 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.
"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.
The rich antioxidants present in matcha tea help in cancer prevention, improved mental alertness and clarity, detoxification, free radical scavenging activity, and stronger immune defense. Polyphenols and catechin-rich matcha promotes relaxation and contributes beneficially to prevention and treatment of various medical conditions. These include bacterial, fungal, and viral infections, cancer, and type-2 diabetes. Matcha tea also assists in maintaining cardiovascular health, gastrointestinal health, and works as a superb energy booster.
Every day, countless people throw away valuable antioxidants and minerals. While seemingly unimaginable, that’s exactly what happens when you brew a cup of green tea because water can only extract a fraction of green teas benefits. The majority actually remains unused, trapped in the tea leaves. In reality, the only way to truly take advantage of green teas full potential is to consume the entire leaf. But that doesn’t mean you need to start eating tea leaves. The simplest solution is to just enjoy a bowl of matcha. Because matcha is straight, stoneground tea leaves, matcha provides you with green teas powerful arsenal of vitamins, minerals, antioxidants, and amino acids in a way no other green tea can.
Like black and green tea, rooibos is rich in polyphenols, such as rutin and quercetin. Cell and animal studies, mostly from South Africa, have shown that rooibos extracts have antioxidant, immune-stimulating, and anti-cancer properties. But studies of rooibos tea in people are limited. There’s little or no evidence to back claims that it relieves constipation, headaches, eczema, asthma, insomnia, high blood pressure, mild depression, ulcers, diabetes, and so on.
Certain studies indicate that intake of flavan-3-ols and/or anthocyanidins found in green tea may improve glycemic control and help normalize blood sugar levels. Due to its anti-inflammatory properties, green tea is believed to be beneficial for those who are at-risk or diagnosed with type 2 diabetes. Green tea’s catechins, especially EGCG, appear to have anti-obesity and antidiabetic effects.
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.
10. Stop complaining for the next 100 days. A couple of years back, Will Bowen gave a purple rubber bracelet to each person in his congregation to remind them to stop complaining. “Negative talk produces negative thoughts; negative thoughts produce negative results”, says Bowen. For the next 100 days, whenever you catch yourself complaining about anything, stop yourself.
The rooibos plant is endemic to a small part of the western coast of the Western Cape province of South Africa. It grows in a symbiotic relationship with local micro-organisms. Scientists speculate that climate change may threaten the future survival of the plant and the R600-million (approximately €43-million in March 2017) rooibos industry. Some claim that increasing temperatures and decreasing rainfall may result in the extinction of the plant within the next century.
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.
I wasn't a tea drinker before getting this tea, and I have to admit, I really like it. I have about 2-3 glasses per day with just a little bit of honey...very good. I bought this tea to see if it would help with my allergies. I doing some research that was one of the claims from several web sites, and it has to be true if it's on the web....right? :) I'm skeptic, but I thought even if it helped a little it would be worth it. So...I don't know if it was a matter of timing and the allergens all dropped the day I started drinking this tea, but I haven't taken an allergy pill in 7 days. I was taking them daily, sometimes twice a day. Don't get me wrong, I wouldn't call this a miracle cure. There are days where I've had some issues with allergies, but congestion has been far less than before. So I have to say that for me, I did seem to help. So even if all the health claims are only 25% true....it's probably worth it. If you're looking for tea that has a nice flavor and no caffeine, give this one a try, I don't think you'd be disappointed.
Tea culture of Korea was actively suppressed by the Japanese during the Japanese forced occupation period (1910‒1945), and the subsequent Korean War (1950‒1953) made it even harder for the Korean tea tradition to survive. The restoration of the Korean way of tea began in the 1970s, around Dasolsa. Commercial production of green tea in South Korea only began in the 1970s,. By 2012 the industry was producing 20% as much tea as Taiwan and 3.5% as much as Japan. Green tea is not as popular as coffee or other types of Korean teas in modern South Korea. The annual consumption per capita of green tea in South Korea in 2016 was 0.16 kg (0.35 lb), compared to 3.9 kg (8.6 lb) coffee. Recently however, as the coffee market reached saturation point, South Korean tea production doubled during 2010‒2014, as did tea imports during 2009-2015, despite very high tariff rate (513.6% for green tea, compared to 40% for black tea, 8% for processed/roasted coffee, and 2% for raw coffee beans).
