Benefits of drinking green tea


Green tea has been consumed for thousands of years but it has now become a really popular drink.

So, why is green tea good for you?

  • Green tea is made from unfermented tea leaves and contains a higher concentration of antioxidants than black tea because it is less processed (1).   Research suggests that antioxidants help the body to fight disease by preventing cell damage and remain healthy
  • Green tea contains:

- EGCG  (Epigallocatechin Gallate), one of the most powerful compounds in green tea, which has been shown to reduce LDL cholesterol (2)

- L_theanine, which increases the activity of GABA, an inhibitory neurotransmitter which has calming properties, so regularly drinking green tea can have a relaxing effect, reduce stress and enhance your mood (3)

  • Green tea can help to boost the metabolism and has been shown to increase fat metabolism (4)
  • Researchers have investigated whether green tea polyphenols may protect against some kinds of cancer (5) (6)
  • Green tea has been shown to benefit those with arthritis due to its anti-inflammatory properties (7)
  • Catechins in green tea can have protective effects for the brain (8)
  • Green tea does contain caffeine, just not as much as black tea

My Top Tips when making green tea

  • Don’t use boiled water as it can damage the catechins. So, boil the water and allow it to cool for a few minutes before using
  • Steep for 1-2 minutes before pouring into a cup or removing the teabag
  • Green tea does contain tannins which can interfere with iron absorption so try to avoid drinking with an iron rich meal

There are different types of green tea and the most commonly used is Sencha. Matcha is a Japanese powdered green tea which is 10 times as nutrient rich as other green teas because when you drink this tea you consume the leaves and all of the antioxidants they contain.


The effects of green tea catechins may not be similar in all individuals. Green tea may interact with some medications, including heart medication, so please check with your GP first.
