Chinese people have been drinking tea for thousands of years and it’s generally believed drinking tea is a very healthy way of living. Recent medical research has shown drinking tea regularly can help people lower LDL Cholesterol (also known as bad cholesterol), reduce the risks of getting a cardio disease, cancer, and strokes, prevent diabetes, improve your metabolism and immune system. It can also reduce the chances of getting Alzheimer's so based on research tea is a great thing to drink.
Dr. John Weisburger suggested that no matter what kind of tea, whether it be green or black tea, all come from the same plant called Camellia Sinensis. The real difference between black and green tea is due to the way they are made. Black tea is made from fermentation while green tea doesn’t pass through this process. During fermentation, many of the natural benefits from the tea can be reduced or damaged due to the fermentation process.
Black Tea Research
Previous research held instigated by the Netherlands National Institute of Public Health and the Environment found a connection between the consumption of black tea and reduced changes of having a stroke. Researchers looked at data from a study examining the health benefits of foods that are high in flavonoids—phytonutrients with antioxidant benefits.
While some of the flavonoids were obtained from fruits and vegetables, seventy percent came from black tea. The study looked at 552 men over a 15 year period. Researchers concluded that the flavonoids in black tea helped reduce the production of LDL—the "bad" cholesterol that can lead to stroke and heart attacks. Furthermore, men who drank over four cups of black tea per day had a significantly lower risk of stroke than men who drank only two to three cups per day.
Green Tea Research
Green tea contains the antioxidant EGCG which contains medicinal properties that can be used to treat various diseases.
Green tea contains caffeine, which is a known stimulant that has been shown to improve brain function including better moods and more focus. While the caffeine content isn’t as strong as coffee, green tea also contains the amino acid L-theanine which can also improve brain function and reduce anxiety.
Regular consumption of green tea can help burn fat and improve physical performance.
Green tea is great for your teeth. The catechins in green tea can kill bacteria in your mouth and also help prevent you from catching influenza.
A study in 40,530 adults in Japan showed those who drank five or more cups of green tea were significantly less likely to die over a 10 year period. On average from all causes, the reduction in chances of death was 23% with women and 12% with men.
