Green tea
All types of tea, even your regular cup of builder’s, come from the Camellia sinensis plant. Green tea gets its name from the emerald green color created when brewing unprocessed, unfermented tea leaves. With origins going back as far as 5,000 years, green tea is commonly drunk and widely grown in the Far East where the health properties are well regarded.
Nutritional highlights
There are many health claims surrounding green tea from a reduced risk of cancer to weight loss. The evidence to support these claims is largely inconclusive. Some of the health claims are based on ancient Eastern traditions, where green tea has been used to treat symptoms of disease for years. Because of the proposed benefits, many ‘health’ products now include traces of green tea. However, there is limited evidence to suggest these products are effective. If you are hoping to use green tea for medicinal purposes, make sure to consult your doctor first.
Green tea does have more health benefits than black tea which can be attributed to its lack of processing. Green tea is higher in protective polyphenols. The major polyphenols in green tea are flavonoids, the most active of which are catechins and epigallocatechin gallate (EGCG) which function as powerful antioxidants. Antioxidants are known to protect the body against disease and are an important part of a healthy diet. Antioxidants can be found in a range of fruits, vegetables and other unprocessed foods. As part of a balanced diet, green tea can be a good source of antioxidants.
How much caffeine does green tea contain?
An equal quantity of green tea contains less caffeine than coffee (one cup of green tea contains approximately 35-80 mg compared to approximately 100-400 mg in the same size cup of coffee), but it can still act as a stimulant. As a result, some people find that drinking green tea increases energy levels, concentration and mood, but this effect may vary between individuals
