How much caffeine does green tea contain? Here's what you need to know before consuming it

Green tea is an increasingly popular drink.

Coffee is the first drink that starts the day. About 62% of Americans drink coffee on a daily basis, according to data from the National Coffee Association in 2020. But let's not forget teas that contain caffeine, especially green tea, another drink that has caffeine, but also some health benefits.

Since the caffeine content of different types of tea can vary, and some contain no caffeine at all, many people wonder if green tea contains caffeine. The short answer is, yes.

Why does green tea contain caffeine?

Green tea is made from the leaves of the Camellia sinensis plant, and since this plant naturally contains caffeine, so does the resulting tea. Unless the tea has undergone a decaffeination process, all types of green tea will contain some amount of caffeine. However, not all types of green tea will contain the same amount of caffeine.

"The caffeine content of green tea can vary depending on the type of tea," says Jena Volp, registered dietitian for Real Simple. Varieties like matcha and sencha are examples of green teas with the highest caffeine content.

The caffeine content of green tea can vary. One cup of brewed green tea contains about 28 milligrams of caffeine, according to the Mayo Clinic. However, as mentioned, there are many factors that can affect the caffeine content of green tea, so there may be times when it is higher.

Matcha green tea

Matcha green tea has the most caffeine of all types of green tea.

– Matcha is a special type of green tea that involves grinding the tea leaves into a fine powder. Since drinking catnip means consuming the entire powdered leaf, it has more caffeine. Researchers estimate that the caffeine in black tea is between 18.9 and 44.4 mg per gram – almost twice as much as regular green tea. A typical serving of a kitty is about 2 grams, which would add up to 88.8 mg of caffeine per cup, Los Angeles-based nutritionist Maggie Moon explains to Real Simple.

Sencha është gjithashtu një çaj jeshil me përmbajtje të lartë kafeine. Një tjetër çaj jeshil i popullarizuar japonez, ai gjithashtu përmban më shumë kafeinë sesa çaji jeshil tipik. Nuk ka aq shumë kërkime mbi përbërësit e gjetur në gri në krahasim me çajrat e tjerë, por besohet se përmban deri në 75 mg kafeinë për filxhan.

Sa kafeinë është në rregull për të konsumuar në baza ditore?

Kufiri i sipërm i kafeinës për shumicën e të rriturve është rreth 400 mg në ditë, por ky numër duhet të merret gjithmonë me një kokërr kripë, pasi jo çdo trup është i njëjtë.

"It's important to be aware of all sources of caffeine in foods and beverages, including caffeine in green tea, because caffeine is a psychoactive stimulant that affects people differently," Moon says, adding that some people are more sensitive. to caffeine than others. There are also groups that should limit their caffeine intake, such as children and women who are pregnant or breastfeeding.
