Green tea is loaded with antioxidants and nutrients that have powerful effects on the body. This includes improved brain function, fat loss, a lower risk of cancer and many other incredible benefits.
Many of the bioactive compounds in the tea leaves do make it into the final drink, which contains large amounts of important nutrients.
It is loaded with polyphenols like flavonoids and catechins, which function as powerful antioxidants. These substances can reduce the formation of free radicals in the body, protecting cells and molecules from damage. These free radicals are known to play a role in aging and all sorts of diseases.
It also has the amino acid L-theanine, which is able to cross the blood-brain barrier. L-theanine increases the activity of the inhibitory neurotransmitter GABA, which has anti-anxiety effects. It also increases dopamine and the production of alpha waves in the brain.
Studies show that caffeine and L-theanine can have synergistic effects. The combination of the two is particularly potent at improving brain function.
Green tea has been shown to increase fat burning and boost the metabolic rate, in human controlled trials.
Not only can green tea improve brain function in the short term, it may also protect your brain in old age. Multiple studies show that the catechin compounds in green tea can have various protective effects on neurons in test tubes and animal models, potentally lowering the risk of Alzheimer’s and Parkinson’s.
Studies show that green tea can improve insulin sensitivity and reduce blood sugar levels.
Green tea also dramatically increases the antioxidant capability of the blood, which protects the LDL cholesterol particles from oxidation, which is one part of the pathway towards heart disease.
