Green tea owes its name to the yellow-green color of the brew, resulting from the brewing of unfermented and almost unprocessed leaves of tea bush. It is considered one of the healthiest drinks, especially when it comes from certified organic tea gardens.
Nutritional values of green tea
There are many opinions regarding green tea and its various health properties, from weight loss help to cancer prevention. However, the evidence supporting these claims is ambiguous. Some of it suggests that green tea drinkers have lower rates of some cancers, but more research is needed to confirm that. Existing clinical trial results do not give clear answers.
Green tea generally has more health benefits than black tea, mainly due to the low level of green tea processing level. Green tea has a much higher content of protective polyphenols. The main polyphenols contained in green tea are flavonoids, of which the most active are catechins and epigallocatechin gallate (EGCG). They act as powerful antioxidants.
Antioxidants prevent cell damage by free radicals and reduce inflammation in our body. Therefore, they are considered components that protect the body against diseases and are an important part of a healthy diet. Antioxidants can be found in fruit, vegetables and other unprocessed products. They are also found in large quantities in green tea, and as part of a balanced diet, green tea can be a great source of antioxidants. Among the different types of green tea, matcha tea contains the most antioxidants.
How much caffeine does green tea contain?
Green tea contains caffeine, although different brands and varieties of green tea can vary significantly. Matcha tea contains the most caffeine among green teas.
Green tea does not contain as much caffeine as coffee, but enough to stimulate the body. On average, one cup of green tea contains about 35-80 mg of caffeine, compared to about 100-400 mg of caffeine contained in a cup of coffee.
However, in addition to caffeine, green tea also contains the amino acid L-theanine, which has a relaxing effect on our body. Due to the lower content of caffeine and at the same time the relaxing effect of L-theanine, green tea causes a different type of energy supply: stable, longer, evenly distributed. Many people think that drinking green tea increases their energy levels, concentration and mood.
Green tea and iron levels
Green tea contains tannins that may interfere with iron absorption. Therefore, nutritionists recommend that you do not drink green tea along with iron-rich meals. It is best to keep an hour break after such a meal, before drinking a cup of tea. For this reason, pregnant women should also watch out for excessive consumption of green tea.
