Regulates Blood Sugar Levels

When the body doesn’t use insulin properly or produces insufficient insulin, type 2 diabetes is associated with high blood sugar levels. A review and analysis of 19 studies involving over 1 million adults in eight countries found that drinking at least four cups of black, green, or oolong tea per day over ten years may contribute to a reduced risk of type 2 diabetes.15 Studies show that green tea may protect against type 2 diabetes by regulating blood sugar levels and improving insulin resistance. A study on Chinese adults found that drinking green tea on a daily basis is associated with a lower risk of type 2 diabetes, as well as a lower risk of diabetes-related health complications and mortality in people with diabetes.17 Protects Against Certain Types of Cancer Green tea is rich in polyphenols, which help fight free radicals and may help protect cells and DNA from damage.18 The antioxidant properties in green tea also play a role in the prevention of cancer.

There is a link between oxidative damage and chronic inflammation, which can lead to the development of cancer.19 Research indicates that the antioxidants in green tea may reduce the risk of certain types of cancer, including:

Breast cancer: Green tea consumption may reduce breast cancer risk by 15%20. Colorectal cancer: Green tea drinkers have a 30%–40% lower risk of developing colorectal cancer, according to studies.21 Oral cancer: Keep in mind that drinking green tea on its own will not lower your risk of developing oral cancer22. However, studies have shown that drinking tea on a regular basis is linked to a lower risk of developing the disease. Improving your overall health necessitates practicing healthy lifestyle habits.
