Dr. Shen Yonghua
Drinking tea has various effects on health, including both benefits and potential adverse factors.
Benefits:
1. Prevents dental caries: Fluorides in tea strengthen teeth against acid attacks and reduce the occurrence of tooth decay.
2. Resists ultraviolet radiation and delays aging: Tea polyphenols in tea protect against UV damage, reduce skin injury, and help maintain a youthful appearance.
3. Lowers lipids and aids weight loss: Catechins found in green tea help reduce cholesterol levels, promote fat metabolism, and assist in weight loss.
4. Antioxidant effects: Tea polyphenols have strong antioxidant properties, helping to eliminate free radicals, delay aging, and prevent cardiovascular diseases.
5. Promotes digestion: Moderate tea consumption helps stimulate gastrointestinal motility and improve digestive function.
Drawbacks:
1. Gastrointestinal discomfort: Drinking strong tea on an empty stomach or consuming excessive amounts of tea may irritate the gastric mucosa, causing stomach pain and excess stomach acid.
2. Insomnia: The caffeine in tea may stimulate the central nervous system, leading to insomnia.
3. Impairs iron absorption: Tannins in tea can bind with dietary iron to form compounds that are difficult for the body to absorb. Long-term, excessive tea consumption may interfere with iron absorption and lead to anemia.
