Green tea

Definition

Green tea is a type of tea made from the unfermented dried leaves of the Camellia sinensis plant. Green tea is consumed throughout the world and has been used medicinally for many years for its various health benefits.

Health considerations

Studies of green tea have shown many beneficial qualities, though results are not always conclusive and may be conflicting between studies. These properties include a high antioxidant capacity, associations with a decreased cancer risk, improved regulation of blood sugar, prevention of liver problems, increased metabolism, lower risk of heart disease, and anti-inflammatory properties.

Keep in mind

There is caffeine in green tea unless it is labelled as decaffeinated, though even then there may still be small amounts of caffeine in the tea. The longer a tea is steeped for, the more caffeine it has. Quality of tea leaves varies significantly, which can affect the nutrient profile.
