Green Tea Helps Balance Blood Sugar And Prevent Diabetes
A meta-analysis of 17 previously published studies looked at the relationship between green tea, blood sugar control, and insulin sensitivity in humans. Researchers found favorable effects. Green tea helps reduce fasting blood sugar levels, as well as values for Hb A1C, a measure of average blood sugar over the previous three months.
Another study in Japanese adults from 23 communities followed over 14,000 healthy people for five years. Scientists found that the consumption of green tea was inversely associated with the risk of;developing diabetes, even after adjusting the data for age, sex, body mass index, and other risk factors. In other words, there is something about green tea that is itself protective.

Active Ingredients According To Preparation
Preparation of Green Tea
The correct preparation of green tea, in particular the brewing time and water temperature, plays an important role in the extraction and preservation of the ingredients. By infusing and steeping;the tea leaves in hot water, the active ingredients are dissolved in a bioavailable form in tea water. The key factor;to consider;is that different substances are transferred to the water in varied;concentrations at different temperatures and brewing;times. The already high complexity of this process is further increased by the fact that the substances often influence each other or even bind to each other. And it is particularly important that the ingredients are heat-stable in different ways and do not evaporate;or decompose;above certain temperatures .;The balance between too low and too high a water temperature and brewing;time therefore determines the composition of the active ingredients;in tea water. For each type of green tea or tea there is an optimum, or the best possible compromise, in the choice of these factors. Green tea should also be drunk quickly after preparation, as certain valuable ingredients decompose relatively quickly in hot water and air after about 10 minutes.;Further reading: Green Tea Preparation.

Green Tea In East Asia
Tea seeds were first brought to Japan in the early 9th century by the Buddhist monks Saicho and Kkai. During the Heian period , Emperor Saga introduced the practice of drinking tea to the imperial family. The Zen Buddhist priest Eisai , founder of the Rinzai school of Buddhism, brought tea seeds from China to plant in various places in Japan. Eisai advocated that all people, not just Buddhist monks and the elite, drink tea for its health benefits.
The oldest tea-producing region in Japan is Uji, located near the former capital of Kyoto. It is thought that seeds sent by Eisai were planted in Uji, becoming the basis of the tea industry there. Today, Japan’s most expensive premium teas are still grown in Uji. The largest tea-producing area today is Shizuoka Prefecture, which accounts for 40% of total Japanese sencha production. Other major tea-producing regions include the island of Kyushu and the prefectures of Shiga, Gifu, and Saitama in central Honshu.
All commercial tea produced in Japan today is green tea, though for a brief period black tea was also produced in the late 19th and early 20th centuries. Japanese tea production is heavily mechanized, and is characterized by the use of modern technology and processes to improve yields and reduce labor. Because of the high cost of labor in Japan, only the highest quality teas are plucked and processed by hand in the traditional fashion.
Popular Japanese green teas include:

Possible side effects of matcha Matcha doesnt appear to cause significant side effects when consumed in moderation, but high doses providing large amounts of caffeine may cause headaches, diarrhea, insomnia, and irritability. While matcha tea is generally safe to consume, drinking too much in a day could be harmful.
Import Of Radioactive Japanese Tea
On 17 June 2011, at Charles de Gaulle airport in Paris, France,radioactivecesium of 1,038 becquerels per kilogram was measured in tea leaves imported from Shizuoka Prefecture, Japan as a result of the Fukushima Daiichi nuclear disaster on 11 March, which was more than twice the restricted amount in the European Union of 500 becquerels per kilogram. The government of France announced that they rejected the leaves, which totaled 162 kilograms .
In response, the governor of Shizuoka Prefecture, Heita Kawakatsu, stated: “there is absolutely no problem when they drink them because it will be diluted to about 10 becquerels per kilogram when they steep them even if the leaves have 1,000 becquerels per kilogram;” a statement backed by tests done in Shizuoka. Japanese Minister for Consumer Affairs and Food Safety Renh stated on 3 June 2011 that “there are cases in which aracha are sold as furikake and so on and they are eaten as they are, therefore we think that it is important to inspect tea leaves including aracha from the viewpoint of consumers’ safety.”
In 2018, the US Food and Drug Administration updated its import status on Japanese products deemed to be contaminated by radionuclides, indicating that tea from the Ibaraki prefecture had been removed from the list by the Government of Japan in 2015.

What The Research Shows
Green tea has been shown to improve blood flow and lower cholesterol. A 2013 review of many studies found green tea helped prevent a range of heart-related issues, from high blood pressure to congestive heart failure.
Whatâs good for the heart is usually good for the brain; your brain needs healthy blood vessels, too. In one Swiss study, MRIs revealed that people who drank green tea had greater activity in the working-memory area of their brains. Green tea has also been shown to help block the formation of plaques that are linked to Alzheimer’s disease.
Green tea seems to help keep blood sugar stable in people with diabetes. Because catechins lower cholesterol and blood pressure, they can help protect against the damage a high-fat diet can cause, Ochner says.

Your Alertness And Brain Health May Improve By Drinking Green Tea
One of the most popular features of green tea, according to the;NCCIH, is mental alertness. This short-term effect is linked to green teas caffeine content. Caffeine itself is a stimulant to the central nervous system, which can cause issues when consumed in large amounts. But the low caffeine content in green tea is just enough to wake you up without causing the anxiety and jitters associated with higher-caffeine products, such as coffee.
Catechins May Reduce Iron Absorption
The catechins in green tea may reduce your ability to absorb iron from foods (
While regularly drinking green tea isnt a concern for most healthy individuals, those at risk of iron deficiency should consider drinking tea in between meals and waiting at least one hour after eating before drinking tea .
Infants, young children, women who are pregnant or menstruating and individuals who have internal bleeding or are undergoing dialysis are all at an increased risk of iron deficiency.
The catechins in green tea can also interfere with certain medications and decrease their effectiveness.
For example, studies indicate that green tea may inhibit the effectiveness of certain heart and blood pressure medications .
Drinking green tea may also decrease the effects of certain medications used to treat anxiety and depression .
Toxic effects are most common when people take green tea supplements, which have a much higher concentration of catechins than green tea itself .
Summary: When consumed in moderation, green tea is safe for most people. You may want to limit or avoid it if you have iron deficiency or are pregnant, nursing or taking medications for anxiety disorders or heart conditions.

How To Make Matcha Green Tea
Youll find my full matcha green tea recipe and measurements below, but because there are a few tricks to making matcha, I wanted to break it down step by step. Heres what you need to do:
First, sift it into a small bowl or mug. Matcha clumps very easily, so I always recommend sifting it before you add any water. Otherwise, it will be difficult to get the tea to disperse evenly in the liquid, and your drink will be lumpy.
Then, pour in a small amount of hot water, and whisk.;But wait! This isnt the circular whisking required for making baking recipes or scrambled eggs. Instead, whisk vigorously from side to side either directly back and forth or in a zigzag pattern to evenly disperse the powder in the water and create a foamy layer on top. If you whisk in a circular motion, your tea wont foam.
Finally, top it off with more hot water or steamed milk. Traditional matcha green tea is made with just green tea powder and water, but you can also easily make a latte by finishing your drink with steamed milk. I love to make mine with almond milk, coconut milk, or homemade oat milk. Whisk again until foamy, sweeten to taste, and enjoy!
How To Prepare Matcha Tea
Matcha is brewed differently than other types of green tea. Instead of steeping a tea bag and removing it, you’ll add matcha powder to a cup of hot water. With matcha, you consume the entire tea leaf.;
- Boil water and add 8 to 12 ounces to a mug.;
- Add 1 or 2 scoops of matcha powder .;
- Use a matcha whisk to blend the powder into the water until the mixture is frothy.
- Add honey or sugar for a sweeter flavor.;
Matcha powder can also be mixed with milk or a dairy alternative to make a creamy latte or added to a smoothie. Once you’ve finished brewing, have a seat, take a sip, and enjoy your healthy beverage.;
