Tea leaves have a high content of special compounds called tea polyphenols, which have wide range of health effects for our bodies. The most important one is its strong antioxidant effect, which means the ability to eliminate free radicals in our bodies.
Regular consumption of tea can lead to reduced risk of many types of cancer and other diseases, including cardio-vascular and neuro-degenerative diseases.
- tea makes us more active, concentrated and awake (due to its caffeine content)
- tea can stimulate dopamine in the brain, improving our mood
- tea can make us more creative!
- some types of tea with high concentration of amino acids can also have a soothing effect on our nervous system, improving our sleep
- tea helps us with digestion, especially with digestion of high fat food and some types of tea can help with balancing our intestine micro-flora
- tea, especially big-leaf tea can help balancing our blood sugar and blood lipid level
- tea, especially white tea is very good for our skin, having a strong anti-ageing effect
In comparison to coffee, tea (except for some tea with extreme polyphenols and caffeine content) poses only little pressure on our cardio-vascular system. The effect of caffeine on our body is regulated by certain amino acids contained in tea leaves!
A human study found an interactive effect of a combination of caffeine and L-theanine indicating that L-theanine antagonised the caffeine-induced rise in blood pressure but had no significant effects on blood pressure when ingested alone. L-theanine and caffeine in combination appear to improve, significantly, aspects of memory and attention to a greater extent than caffeine alone (Owen et al. 2013).
If you still worry about caffeine, you can just skip the first two infusions, since it usually contains about 70% of the total caffeine content of the leaves.
Wanna be more creative? The current research demonstrates that drinking tea can improve creative performance with divergent thinking (Yan et al 2017).
