Talking about tea’s health benefits, it is well-known all over the world. Every sort of tea has its own health benefits. They are healthy because of different reasons. Black tea, the one this article talk about, is beneficial due to its unique making process: fermentation. When speaking of the word fermentation, it specifically refers to black tea‘s fermentation. Yet other kinds of teas are also fermented in vary degrees during making, such as oolong tea, white tea, dark tea and yellow tea. Fermentation is the key process of making black tea. The chemical change of polyphenols produces the special aroma and color of black tea, as well as its health benefits.
Thearubigins – The Benefits of Fermentation
Fermentation is aiming to promote the oxidization of polyphenols, which will produce thearubigin and theaflavin. They are the key factors that form the color and flavor of black tea. Thearubigin exists in black tea, is a kind of golden pigment produced in fermentation. Beside of adjusting the color of tea liquid, thearubigin has many health benefits. It can combine with cholesterol in stomach and intestines, and reduce the amount of cholesterol absorbed from food. Thus thearubigin is helpful for protecting your heart from hyperlipidemia and heart disease without any side-effect.

Lose Fat and Lower Triglyceride Content In Blood:
Thearubigin in black tea can reduce the absorbing of cholesterol in stomach and intestines; in the meantime it helps to restrain the synthesis of cholesterol. This efficacy is because of thearubigin’s ability of weakening FAS (fatty acid synthetase). FAS is the primary enzyme of producing fat. That’s also the reason why thearubigin can help reducing the amount of triglyceride in blood.
Black tea contains higher amount of flavone than other kinds of teas. Flavone is able to protect heart and vessels. Being the power source of blood circulation, human’s heart will beat at the average rate of 70 times per minute. Presume a man is 70 years old; then in the past 70 years, his heart should have beaten for over 2.6 billion times. Too much fat in blood will bring big pressure to the heart. The fat will stack on vessel wall. As a result, vessels will be blocked, causing cerebral infarction and poor blood flow. However, flavone can ease these uncomfortable feelings. So drinkingblack tea can protect your heart from cardiovascular disease.
More Benefits of Black Tea for Your Health
Protecting bones: polyphenols in black tea can restrain the active matters which harm bone cells. There are research findings that people who drink black teas regularly have stronger bones. To prevent osteoporosis, you can drink a cup ofblack tea every day, and keep as a habit for years. If you add lemon into black tea, you will have a better effect of protecting your bones.Black tea can be mixed with other fruit as well.
Protecting stomach and intestines: the enzymatic oxidization happens during fermentation will reduce the amount of polyphenols in black tea. Thus black tea becomes gentler, and will have red liquid and red leaves. Furthermore, as polyphenols may stimulate stomach, which acts stronger in an empty belly, black tea with lower polyphenol amount can help to protect your stomach. Black tea can be mixed with sugar and milk. Regular drinking of it can diminish inflammation in your stomach, and protect stomach lining, even help to cure gastric ulcer.
