Green tea is good for you primarily because it is rich in protective plant compounds called polyphenols, especially catechins like epigallocatechin gallate (EGCG), which act as antioxidants. These compounds contribute to many health benefits including antioxidant effects, brain protection, support for metabolism and blood sugar control, reduced risk of heart disease, and potentially lowering the risk of certain cancers. Additionally, green tea contains caffeine and the amino acid L-theanine, which together may improve focus, promote calmness, and enhance cognitive function. Regular consumption of green tea is also linked to lower cholesterol, better bone health, and may help reduce dementia risk and support longevity when included as part of a healthy diet.

Consumption Tips
- Drinking 2-3 cups daily is often recommended for health benefits.
- Best enjoyed without milk, which might reduce antioxidant effects.
