1. Antioxidant effect
Green tea contains a lot of tea polyphenols, which has a very strong antioxidant effect. Studies have shown that tea polyphenols can resist the damage of free radicals and protect cells from oxidative stress. In addition, tea polyphenols can also prevent DNA oxidative damage, thus slowing down the aging process.
Lower cholesterol
Tea polyphenols in green tea can reduce the blood cholesterol level, especially the content of low density lipoprotein cholesterol (LDL-C). This is because tea polyphenols can inhibit the absorption and oxidation of cholesterol, thus reducing the cholesterol content in the blood.
3. Reduce the incidence of cardiovascular diseases
Studies have shown that green tea can reduce the risk of coronary heart disease and stroke. This is because tea polyphenols in green tea can lower blood pressure, reduce platelet aggregation and improve vascular endothelial function.
4. Improve cognitive function
Tea polyphenols in green tea can improve attention, reaction time and memory. Studies have shown that tea polyphenols can increase the contents of dopamine and adrenaline in the brain, thus improving cognitive function.
5. Reduce cancer risk
Tea polyphenols in green tea can inhibit the growth and spread of tumor cells. Studies have shown that tea polyphenols can inhibit the occurrence of common cancers such as breast cancer, colorectal cancer and prostate cancer.
Protect the liver
Tea polyphenols in green tea can protect the liver from damage. Studies have shown that tea polyphenols can inhibit hepatocyte injury, hepatitis virus infection and liver tumors.
Generally speaking, green tea has many beneficial effects on human health. Although green tea is not everything, moderate consumption of green tea can have a positive impact on the body. Therefore, we should drink green tea in moderation every day to keep healthy.
