Green Tea: Good for You

Updated on July 27, 2012

Green tea benefits have been well-known for many centuries. The earliest uses of green tea were for medicinal purposes. Though people drink green tea for its refreshing flavor, the beverage continues to have health benefits. Nothing has changed the fact that green tea is good for you. Here are some facts about the green tea good for you qualities.

As early as the third century, green tea was consumed as a medicine for digestion and nervous disorders or depression. There have been many studies on the health benefits of green tea. It is difficult to have an accurate study using a large sample of human participants since other dietary factors can greatly affect the results. However, there have been many studies about the green tea benefits using humans or animals.


Green tea is still used as a home remedy for depression. The antioxidant in tea called theanine is thought to be responsible for its uplifting qualities. This natural ingredient in tea may encourage relaxation and decrease stress. Several reputable health websites continue to promote the use of green tea for depression.


There also is evidence that those ancients who used green tea for digestion may have been on to something. Green tea is a natural anti-inflammatory remedy. Studies have shown that green tea can assist in alleviating digestive symptoms from inflammatory diseases like Crohn's disease, colitis, and inflammatory bowel disease (IBD). However, tea contains caffeine which can cause stomach upset and other digestive discomforts in people who are not used to consuming any caffeine.


Recent studies show that there may be some benefits of green tea for cancer. The beverage may reduce the risk of certain cancers and slow the growth of cancer cells. One of the cancers that seems to be inhibited by green tea is prostate cancer.

Alzheimer's and Dementia

Black tea and green tea may be helpful for preventing Alzheimer's disease and age-related dementia. Tea that is ingested is broken down into chemical compounds that may have the ability to protect brain cells from these conditions.

Weight Loss

Many resources state that green tea aids in weight loss. Some people may be cynical about this green tea benefit since the weight loss industry is constantly touting various natural ingredients in products being sold as being weight loss wonders. There is some scientific evidence that green tea may reduce abdominal fat and increase the percentage of calories that the person burns.

The scientific studies that draw these conclusions were conducted on rats rather than humans. Some experts believe these results need to be duplicated with more studies on the weight loss and green tea connection in humans before people use green tea as a weight loss home remedy.

One study about the use of green tea for weight loss that was conducted on humans involved drinking tea with green tea extract. Participants who drank a bottle of tea with green tea extract every day lost more weight than people who drank regular tea.

Using Green Tea

Some of the studies show that the ingestion of the beverage is more effective than taking a green tea supplement. This is generally accepted as true for a wide range of supplements as the body gets more benefit from the vitamins and minerals that are naturally ingested in food.

Though several studies say that the best green tea good for you benefits come from drinking four cups of green tea a day, some show that one serving is beneficial. People who are sensitive to caffeine may need to take precautions before drinking large amounts of tea or drinking tea late in the day.
