Green tea is one of the most popular drinks in the world and a wellness classic. Here's what it's good for, how to brew it properly, and how much to drink.
What is green tea?
Green tea comes from the Camellia sinensis plant — the same as black tea, but less oxidized. That keeps its antioxidants, mainly catechins.
Benefits of green tea
1. Rich in antioxidants
Its catechins help fight oxidative stress. This is its most recognized property.
2. Steady energy
It contains less caffeine than coffee, plus L-theanine, for a calmer, more stable energy.
3. Supports weight management
It's studied as part of weight-management diets, always alongside good nutrition and exercise.
How to brew green tea (without bitterness)
Heat water to about 80 °C (175 °F) — just before boiling.
Pour over 1 tsp of green tea or one tea bag.
Steep for only 2–3 minutes.
Remove the leaves to avoid bitterness.
