Maybe it’s time to trade in your morning coffee for a cup of green tea. If you enjoy coffee, that may sound shocking. Why would you trade in your cup of Joe for green tea? Well, you may be surprised to learn that there are many more green tea benefits than coffee benefits. And, you can still get your caffeine boost.

What exactly is green tea? Green tea comes from the leaves of the Camellia sinensis plant. Farmers steam the tea leaves immediately upon harvest to prevent fermentation.

Steaming the leaves destroys the enzymes that break down the color pigments in the leaves. This enables the tea to maintain its green color. Then the leaves are rolled and dried to preserve the polyphenols, a natural compound found in plant-based foods. This method of processing the leaves preserves the many health benefits of green tea.

Read on to learn why you should try green tea and enjoy some green tea benefits.

Green Tea Benefits for Your Digestive System

Polyphenols, the predominant natural compound in tea leaves, improve the health of your digestive system. It also reduces your risk of chronic diseases like high blood pressure and heart disease.

“Green tea is classified as cool in nature, sweet and bitter in flavor, and influences the heart, lungs and stomach meridians in TCM. These indications show that green tea reflects the functions of relieving headaches, toothaches, and irritation. It is also capable of resolving phlegm, enhancing food digestion, treating diuresis, clearing heat and detoxifying the body, exhibiting anti-aging function, strengthening teeth, and fighting cancer,” explains Chu I Ta, the Chief Traditional Chinese Medicine (TCM) Physician at Real Health Medical.

1. Green tea promotes weight loss

That’s right, you can drink green tea for weight loss. A study has shown that green tea consumption can help people lose weight by promoting the growth of healthy bacteria in the gut. Another study found that green tea consumption can help to prevent obesity by increasing good bacteria and lowering bad bacteria in the gut.

Use the soft infusion method and steep a bag of green tea leaves for approximately 3 minutes in warm water. To enjoy your cup of tea chilled, you can refrigerate it right after steeping. For a stronger caffeine effect, you may also choose to use 2 teabags. For a sweeter alternative, you can brew a cup of jasmine tea based on green tea leaves.

2. Regular consumption of green tea can help to prevent different digestive system cancers

The polyphenols in green tea also demonstrate antioxidant, anti-mutagenic, and anti-carcinogenic activities that can help to protect against cancers caused by environmental agents. These include cancers of the colon, mouth, pancreas, small intestine, and stomach.

Kombucha green tea is a mildly sweet and sour-flavored beverage. It is manufactured through a natural process involving the fermentation of green tea in urns without adding any yeast for 10 to 12 months. Give this fizzy tea a try and enjoy some green tea benefits.

3. Green tea can help to protect against liver diseases

Similarly, green tea consumption can inhibit the multiplication of fat-storing cells in the liver, which helps to prevent liver fibrosis (permanent scarring of liver tissue) in chronic liver diseases.

4. It has therapeutic effects on inflammatory bowel disease (IBD)

Research has shown that the polyphenols in green tea can reduce the severity of colitis. Colitis is an inflammation of the colon caused by infection or other causes.

Consuming green tea decreases disease activity and inhibits the inflammatory response in chronic inflammatory diseases. Avoid taking green tea with foods that are yin (cold) or bitter in nature. Similarly, women who are experiencing a heavy menstrual flow should avoid drinking green tea as it can increase their risk of iron-deficiency anemia.
