Dr. Shen Yonghua
Benefits and Effects of Green Tea:
1. Antioxidant and Anti-aging: Green tea is rich in antioxidants, especially catechins, which effectively remove free radicals, slow down the cellular aging process, and help prevent skin aging and disease.
2. Promotes Cardiovascular Health: The polyphenols in green tea help lower cholesterol and triglyceride levels in the blood, reduce the risk of atherosclerosis, and provide protective benefits for the heart and blood vessels.
3. Boosts Metabolism: The caffeine and catechins in green tea can stimulate the body's metabolism, accelerate fat burning, and aid in weight loss and weight management.
Contraindications of Green Tea:
Despite its many benefits, green tea is not suitable for everyone. Excessive or improper consumption may pose health risks:
1. Sleep Disturbances: Green tea contains a relatively high amount of caffeine, and excessive consumption may affect sleep quality, leading to insomnia or insufficient sleep.
2. Gastrointestinal Discomfort: Drinking strong tea on an empty stomach may irritate the gastric mucosa, causing discomfort such as stomach pain and nausea, particularly in individuals with excess stomach acid or a history of gastrointestinal disorders.
