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 chances of getting Alzheimer's so based on research tea is a great thing to drink.
But people might be curious about which tea is the best or healthiest.
Dr. John Weisburger suggested that no matter what kind of tea, whether it be green or black tea, all comes 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.
Recent research has shown black tea contains theaflavins and thearubigins which are very good for the human body and can improve your health but this research is still waiting for more breakthroughs.
Another recent research has shown food processed by fermentation can generate something called ethyl carbonate, which is also known as urethane. The WHO (World Health Organisation) and the International Agency for Research on Cancer all believe ethyl carbonate can cause cancer so it’s suggest green tea is healthier than black.
But no matter what, I always highly recommend no matter what you eat or drink, you always consume everything in moderation. There is no perfect food in the world and there are still many medical types of research waiting for breakthroughs. Even green tea contains caffeine which can cause some health risks and issues.
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 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.
