Best Way to Have Green Tea

The effectiveness of green tea also depends on how it is consumed. Here are some recommendations:

• • Green tea bags: Convenient and easy to use. However, due to growing concern about plastic polymers like nylon or PET in triangles or silky tea bags, people are now gravitating towards loose leaves.
  • Loose leaf green tea: Tea bags often contain dust or fannings (very small broken tea particles). Loose leaf ensures better quality and higher antioxidant content
  • Matcha (green tea powder): Did you know, the global sensation “Matcha Tea” is actually made of powdered green tea leaves and stems. It is a more concentrated form of the tea leaf making it more antioxidant rich. So while green tea is consumed lightly brewed without milk, matcha is a full bodied drink that is popularly consumed with milk. Based on your lactose tolerance you can choose either of both.

• Flavoured green teas: There is a plethora of options in green tea brews available in the market. However a pale golden brew such as this must be consumed with simple condiments for better absorption of nutrients, for example:
  

• With lemon: Enhances antioxidant absorption with Vitamin C
