Why green tea is good for you

Green tea has been touted as a superfood by many sources, and with good reason – it’s full of antioxidants, natural flavonoids, and other ingredients that have been shown to improve health and slow ageing.

1. Green tea gives you the power of calm attentiveness
‍The tea amino acid L-theanine has a relaxing, but not sedating, effect. It is renowned for its ability to put you in the ideal state of “calm attentiveness” which can sharpen focus and concentration while reducing stress and enhancing overall well-being. Theanine can interact with caffeine, allowing a smaller dose of caffeine to have a stronger effect in terms of boosting concentration and alertness.

2.  Green tea keeps teeth healthy
‍Catechin and fluorine limits the growth of the bacteria causing tooth decay. Freshen your mouth with a cup of tea after meals!
‍
3.  Green tea burns body fat
‍Caffeine promotes the metabolism of fat. Drinking green tea and engaging in physical activity 20-30 minutes afterwards burns up body fat and acts as a muscle stimulant.
‍
4.  Green tea makes your skin beautiful
Drinking tea maintains the skin’s elasticity, and the vitamin C strengthens capillaries. It also improves the skin’s ability to retain warmth.
‍
5.  Green tea prevents high blood pressure
Tea increases the levels of HLD (good cholesterol) in the blood and inhibits high blood pressure.
‍
6.  Green tea boosts immunity
Thanks to catechins, green tea boosts the body’s defenses against infection, so using it as a gargle protects against viruses.
‍
7.  Green tea balances pH and has antibacterial properties
The strong antibacterial properties of green tea limit oxidation in the body and maintains a good pH balance by promoting the body’s alkalinity. This helps against inflammations and pain due to body acidification.
‍
8.  Green tea prevents food poisoning  
Green tea catechin has a powerful effect on bacteria causing food poisoning and regulates intestinal functions.
‍
9. Green tea lowers blood glucose levels
The conjugated polysaccharide found in green tea helps lowering blood glucose levels and prevent diabetes.  
‍
10.  Green tea prevents ageing
Green tea suppresses the production of free radicals and lipid peroxide, and therefore prevents the onset of physical aging.

Many factors contribute to your preference for a particular tea. Some cultivars have more umami, some have more astringency or bitterness (linked to caffein and catechin).

To adjust the taste of your cup of tea, you can control the water temperature to release different components in different quantities. The higher the temperature, the more caffein and bitterness in your cup, but remember, never use boiling water on your green tea!
‍
1) Amino acids release the umami taste and are easily dissolved regardless of the temperature.

2) Astringency and bitterness are linked with caffein and catechin (tannin). Those are released at higher temperatures. Therefore, high quality tea should be prepared with a lower temperature.

Note that catechin and caffeine have both positive health impact, so they should not be avoided at all costs. Depending on your personal preferences, however, you may want to make sure that not too much of them is released.

Should I drink green tea before going to bed? What about pregnant women or infants?
‍Green tea contains caffeine but not all kinds have the same amounts. Choose a kind of tea with low caffeine levels (like Shira-ore), or simply use about half the amount of leaves. In Japan, in the tea farming areas, babies are given watered down green tea to drink as soon as they start eating solid foods (6-8 months).

Green tea on an empty stomach 
Green tea is rich in caffeine and catechin and so may be tough on an empty stomach. We recommend to drink weakly brewed teas in this case.
