 Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process used to make oolong teas and black teas. It is a popular beverage in many cultures, known for its mild flavor and potential health benefits. Some of the benefits associated with green tea consumption include improved brain function, fat loss, and a reduced risk of certain types of cancer.

Green tea has several potential health benefits, including:

Antioxidants: Green tea contains high levels of antioxidants, which can help protect cells from damage caused by free radicals.

Improved brain function: The caffeine and L-theanine in green tea have been shown to improve brain function and alertness.

Fat loss: Green tea has been shown to boost metabolism and promote fat loss.

Reduced risk of cardiovascular disease: Green tea consumption has been linked to a reduced risk of cardiovascular disease, including heart attack and stroke.

Reduced risk of certain types of cancer: Some studies have found that green tea consumption may be associated with a reduced risk of certain types of cancer, including breast and prostate cancer.

Green tea, like most foods and beverages, also has some potential drawbacks, including:

Caffeine content: Green tea contains caffeine, which can cause negative side effects for some people, such as increased heart rate, jitters, and insomnia.

Interactions with medications: Green tea can interact with certain medications, such as blood thinners and stimulants, and may cause unwanted side effects.

Stomach upset: Green tea can cause stomach upset, such as nausea and indigestion, in some people.


Iron absorption:
Green tea contains tannins that can reduce the absorption of iron from plant-based foods.

Pregnancy and breastfeeding: Green tea should be consumed in moderation during pregnancy and breastfeeding as it contains caffeine and other compounds that can affect the developing fetus and newborn.

It is important to consult a healthcare provider before including green tea as part of a health or wellness regimen to ensure it is safe and appropriate for your individual needs and health conditions.


Green tea, on its own, is a very low-calorie beverage. A cup of plain green tea made from a tea bag contains about 2-4 calories. Adding a small amount of honey or other natural sweeteners can increase the calorie content slightly. Green tea with added ingredients, such as fruit or herbs, may have more calories. It is important to keep in mind that consuming large amounts of green tea can lead to an increase in total calorie intake, which can contribute to weight gain.
