Some tea makers and enthusiasts claim matcha, a powered form of green tea, has more potential health benefits than other green teas. However, few researchers have investigated these claims, and so they remain unsubstantiated. Of course, matcha green tea has the same potential benefits as other forms of green tea, whether or not it is to a larger degree.
Cancer
Population-based studies show that regular consumption of green tea may prevent cancer, according to the University of Maryland Medical Center. For example, in Asian cultures where people tend to drink green tea, the cancer rate stays lower than other areas of the world. Several clinical studies also seem to support this information, citing that the polyphenols in green tea may inhibit the growth and spread of certain types of cancer, including breast, esophageal, lung, prostrate, skin and stomach cancers. Additionally, some research suggests that consuming green tea may improve the survival rates of people with cancer. Conversely, some human studies have turned up no evidence to support the claim that green tea may prevent cancer, warns the University of Michigan Health System.
Brain Function
Your body's metabolic processes generate free radicals, which can cause damage to brain cells. Epigalochatechin-3-gallate, a type of polyphenol found in green tea, possesses potent antioxidant qualities, allowing it to neutralize many of the damaging free radicals. An article on eMedExpert.com points to a population-based study in Japan, which found regular consumption of green tea maintains cognitive function and may improve memory and learning ability. In theory, the protection these polyphenols provide may reduce the risk of neurodegenerative disorders like Alzheimer's and Parkinson's. However, much research is needed to support these claims.
Cholesterol and Cardiovascular Health
Drinking green tea may help balance your cholesterol profile by raising HDL "good" cholesterol and reducing LDL "bad" cholesterol, reports the University of Michigan Health System. Additionally, by reducing the stickiness of the platelets in the blood, green tea may promote cardiovascular health and reduce the risk of heart disease and atherosclerosis. However, the evidence is still preliminary, and green tea lacks the approval of the U.S. Food and Drug Administration.
Diabetes
Traditionally, green tea has functioned as natural method to control blood sugar, but its benefits may reach much further. Recent animal studies suggest green tea may prevent type 1 diabetes, according to the University of Maryland Medical Center. Furthermore, green tea may slow the progression of type 1 diabetes after it has developed. A few small clinical studies indicate that green tea may lower the hemoglobin A1c level in patients with borderline diabetes. However, these findings are preliminary, and you should not use green tea as a substitute for medical treatment or medication.
