Green tea, a commonly consumed type of tea, holds many 'secrets.' How much do you know about them?
Green tea has anti-aging effects
Green tea possesses strong antioxidant and physiological activity, acting as a scavenger for harmful substances in the human body. Research indicates that 1 milligram of green tea can neutralize excess free radicals equivalent to 9 micrograms of superoxide dismutase (SOD), far surpassing other similar substances. It also blocks oxidative reactions and deactivates harmful enzymes. According to Japanese researcher Okuda Takuyu, the anti-aging effect of green tea polyphenols is 18 times stronger than that of vitamin E.
Green tea helps inhibit cardiovascular diseases
Green tea aids in preventing cardiovascular diseases, as its polyphenols play a crucial role in human fat metabolism. High levels of cholesterol and triglycerides can lead to fat deposits in blood vessels, causing atherosclerosis. Polyphenols, particularly catechins like ECG and EGC in green tea, help inhibit plaque formation, reduce blood clotting, and improve circulation.
Green tea helps prevent and fight cancer
Studies show that green tea may help prevent breast, bladder, ovarian, colorectal, esophageal, lung, prostate, skin, and stomach cancers. The catechins in green tea inhibit certain bacteria that cause diseases, while polyphenols protect the digestive tract and reduce the risk of tumors.
Green tea has antibacterial and antiseptic properties
Green tea contains fluoride and catechins that inhibit cavity-causing bacteria. Rinsing with green tea can prevent gum bleeding, kill oral bacteria, and reduce plaque and periodontitis.
Green tea can prevent and treat radiation damage
Drinking green tea has anti-radiation effects, particularly beneficial for those exposed to computer radiation. Iranian scientists found that consuming 1-2 cups of green tea 2-3 hours before radiation exposure significantly reduces damage. British researchers also noted that green tea mitigates skin damage from UV radiation by neutralizing harmful oxidants.
Green tea improves digestion
Recent studies indicate that green tea can alleviate digestive issues, such as acute diarrhea caused by bacteria.
Green tea aids in weight loss
Green tea contains theophylline and caffeine, which activate enzymes that break down fat, reducing fat accumulation and promoting weight loss.
Green tea enhances skin beauty and protects against UV rays
Ground green tea leaves can be used in face masks to cleanse, moisturize, reduce acne scars, and repair skin damage. Rich in vitamin C and flavonoids, green tea also brightens the skin.
