There are so many wonderful things about green tea. Not only is it rich in antioxidants, promotes heart health, aids digestion, and regulates blood sugar and body temperature, but it also raises metabolic rate, and speeds up fat oxidation, and yes, it helps people lose weight.
Green tea also has a powerful effect against rheumatoid arthritis and tumors. The more green tea you drink, the less risk you will have of coronary artery disease. The cholesterol lowering effects of green tea have been confirmed by both animal and human epidemiological studies.
Green tea also releases feel-good Dopamine due to a substance present in green tea called theanine, which is helpful in improving mood and increasing a sense of relaxation. Theanine induces the release of a neurotransmitter called GABA, which tends to calm down the brain. It also triggers the release of dopamine, one of the main brain chemicals associated with well-being. Dopamine is the brain’s master regulator of reward and pleasure. The calming effect of theanine may be the reason that drinking green tea, even with caffeine, does not tend to produce nearly as “jittery” an experience as drinking coffee.
