Green tea is brewed and consumed all over the world because of its remarkable health benefits. But what about matcha green tea? Matcha is essentially another variety of green tea and holds the same powerful benefits as regular green tea.
The practice of preparing and consuming powdered tea such as matcha was first made popular by Chinese over 900 years ago. This ritual was shared with the Japanese in the 11th century, and it was used in traditional Japanese tea ceremonies from there on out. Matcha is grown and prepared differently from regular green tea. Matcha is shade-grown whereas green tea is grown in the sun during the first few weeks of harvest. By growing matcha in the shade, the chlorophyll content level is increased. Here are 5 health benefits of matcha tea, all based on science.
1. High in antioxidants
Matcha is rich in catechins, a class of plant compounds in tea that act as natural antioxidants. Antioxidants help stabilize harmful free radicals, which are compounds that can damage cells and cause chronic disease. When you add matcha powder to hot water to make tea, the tea contains all the nutrients from the entire leaf. It will tend to have more catechins and antioxidants than simply steeping green tea leaves in water. In fact, by one estimate, the number of certain catechins in matcha is up to 137 times greater than in other types of green tea. One study showed that giving mice matcha supplements reduced damage caused by free radicals and enhanced antioxidant activity. Including matcha in your diet could increase your antioxidant intake, which may help prevent cell damage and even lower your risk of several chronic diseases.
2. May help protect the liver
The liver is vital to health and plays a central role in flushing out toxins, metabolizing drugs, and processing nutrients. Some studies have found that matcha may help protect the health of your liver. One study gave diabetic rats matcha for 16 weeks and found that it helped prevent damage to both the kidneys and liver. Another study gave 80 people with nonalcoholic fatty liver disease either a placebo or 500 mg of green tea extract daily for 90 days. After 12 weeks, green tea extract significantly reduced liver enzyme levels. Elevated levels of these enzymes are a marker of liver damage. Furthermore, an analysis of 15 studies found that drinking green tea was associated with a decreased risk of liver disease.
3. Boosts brain function
Some research shows that several of the components in matcha could help enhance brain function. One study in 23 people looked at how people performed on a series of tasks designed to measure brain performance. Some participants consumed either matcha tea or a bar containing 4 grams of matcha, while the control group consumed a placebo tea or bar. The researchers found that matcha caused improvements in attention, reaction time, and memory, compared to the placebo. Another small study showed that consuming 2 grams of green tea powder daily for 2 months helped improve brain function in older people.
4. May help prevent cancer
Matcha is jam-packed with health-promoting compounds, including some that have been linked to cancer prevention in test tube and animal studies. In one study, green tea extract decreased tumor size and slowed the growth of breast cancer cells in rats. Matcha is especially high in epigallocatechin-3-gallate (EGCG), a type of catechin that has been shown to have powerful anti-cancer properties. One test tube study found that the EGCG in matcha helped kill off prostate cancer cells. Other test tube studies have shown that EGCG is effective against skin, lung, and liver cancer. Keep in mind that these were test tube and animal studies looking at specific compounds found in matcha. Further research is needed to determine how these results may translate to humans.
5. May promote heart health
Some studies have shown that drinking green tea, which has a similar nutrient profile to matcha, may help protect against heart disease. Green tea has been shown to reduce levels of total and “bad” LDL cholesterol, as well as triglycerides. It may also help prevent the oxidation of LDL cholesterol, another factor that may protect against heart disease. Observational studies have also shown that drinking green tea is associated with a reduced risk of heart disease and stroke. When combined with a well-rounded diet and healthy lifestyle, drinking matcha may help keep your heart healthy and protect against disease.
