You may have heard about the antioxidant properties of green tea and how it’s a healthy beverage for everyone – here’s a summary of the scientific evidence.

  • Foremost, green tea contains catechins and polyphenols, antioxidants that prevent cell damage, fight cancer and reduce inflammation. Specifically, it lowers the risk of breast, prostate and colorectal cancers
  • Its calorie free (unless you drink Japanese rice green tea and consume the rice) so a good alternative if you are used to juice, milky coffees or soda. Some studies even show green tea increasing metabolic rate, but the physiological mechanism is unclear
  • It can help with insulin resistance, therefore play role in nutrition for those with diabetes
  • It’s lower on caffeine than coffee, but still helps with lifting mood, memory, vigilance and reaction time
  • It contains amino acids that promote activity of the neurotransmitter GABA, which helps with anxiety and relaxation. Some studies have shown green tea to be neuro-protective and reduce the risk of dementia, but larger sample sizes are required on proving this
  • Green tea lowers total cholesterol and low density lipoprotein (so called “bad cholesterol”)
  • In stroke or heart attack survivors, green tea reduces the risk of death by 62%
  • It can improve skin flare-ups including psoriasis
  • It has been shown to even improve bad breath (by reducing Strep bacteria)
  • And in a large study with over a hundred thousand participants, regular green tea consumption is correlated with a longer, healthier and happier life. There is a 31% lower risk of death from cardiovascular disease, and 42% lower risk of death from stroke in regular green tea drinkers!
