Benefits and Risks of Drinking Green Tea

Drinking green tea has multiple benefits and drawbacks, and should be consumed in moderation.

On the positive side, green tea is rich in antioxidants such as catechins and polyphenols, which help delay aging, reduce the risk of cardiovascular diseases, and promote fat burning to aid weight loss. Meanwhile, the caffeine in green tea can refresh the mind and increase alertness. Green tea contains abundant antioxidants, such as catechins, which help combat free radicals, reduce cellular damage, and may lower the risk of cardiovascular diseases and certain types of cancer.

However, excessive consumption of green tea may also cause adverse effects, such as sleep disturbances, gastrointestinal discomfort, and increased burden on the kidneys. Additionally, the tannins in green tea may interfere with iron absorption, increasing the risk of anemia. Therefore, while enjoying the health benefits of green tea, one should pay attention to moderate consumption and avoid overconsumption. High doses of caffeine may cause increased heart rate, insomnia, anxiety, and gastrointestinal discomfort. For individuals sensitive to caffeine, these symptoms may be more pronounced. Excessive consumption may also lead to excessive secretion of gastric acid, damaging the gastric mucosa.
