The ancient secrets of green tea
Green tea is overflowing with antioxidants
Green tea contains polyphenol antioxidants that reduce inflammation in the body, a known trigger of premature aging. These antioxidants also proactively protect cells from damage that can lead to a number of chronic illnesses, making it a superfood that offers a broad range of health protection.
Green tea supports brain health
Green tea is known to elicit an alert calm. While it does provide caffeine, green tea also contains an amino acid called L-theanine, which produces a calming effect. The combination of caffeine and L-theanine has also been shown to optimize brain function to enhance working memory, cognitive performance, and elevate mood. Green tea’s ability to counter oxidative stress also makes it a potent protector against neurodegenerative diseases, including Alzheimer’s and Parkinson’s.
Green tea may support weight management In human and animal research, green tea has been shown to rev metabolism and stimulate fat burning. It is also linked to curbing appetite and preventing fat gain by inhibiting a process known as angiogenesis—the formation of new blood vessels—which fat tissue growth depends on. Green tea protects against cancer Green tea fends off cancer in a few key ways. The plant protects against damage that can trigger the uncontrolled growth of cells, which can lead to cancerous mutations. The anti-angiogenesis effect that helps prevent fat gain also works to block cancer from spreading. Green tea supports immunity Green tea antioxidants offer antibacterial, antifungal, and antiviral effects that support immunity. Bonus: Its antibacterial properties also fight bad breath. In addition, green tea acts as a prebiotic, food for the beneficial gut bacteria tied to healthy immunity. Green tea supports bone density The antioxidants in green tea have been shown to protect against bone loss and reduce the risk of fracture. Animal studies have found that a moderate intake of green tea benefits bone health by improving bone strength and quality. One recent study looked at the connection between polyphenol-rich foods, including green tea, and osteoporosis. Researchers concluded that phenols influence bone mineral density by preventing oxidation-induced damage to bone cells as well as by reducing inflammation, which helps support bone building. The Health Benefits of Decaf Coffee and Tea, According to a Nutritionist 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. Green tea supports heart health Once again, green tea multitasks. In addition to its anti-inflammatory effects and ability to guard against oxidative stress, green tea has been shown to protect the heart by reducing total cholesterol, “bad” LDL, blood pressure, and triglycerides, or blood fats. It also prevents the oxidation of LDL, a process that triggers a domino effect, which contributes to artery hardening and heart disease. A higher intake of the beverage is also tied to a lower risk of stroke. Green tea protects skin from aging Research shows that polyphenols in green tea protect skin from the effects of ultraviolet (UV) light. This helps prevent the acceleration of aging, in addition to offering cancer-fighting and anti-inflammatory benefits. Green tea compounds also help defend against wrinkles, due to their ability to prevent the breakdown of collagen and elastic fibers, which in turn forestall the loss of skin elasticity. Green tea is tied to longevity The cells of regular green tea drinkers have a younger biological age than non-drinkers, by about five years. Japanese research also shows that regular green tea drinkers live longer. In one study in older adults, those who drank the most green tea were 76% less likely to die the six-year study period.
