What are the benefits of Black tea?

Though caffeinated drinks are often discouraged by dieticians, a perfect cup of Black tea with its huge host of health benefits makes it an ideal part of the routine of most people. The benefits of Black tea are due to the unique properties that are yielded to it by the overall fermentation and oxidation process that it goes through. Though Black tea should be consumed without any additives like sugar and milk to reap its benefits in the best manner, even having it with them has few health benefits.

What gives Black tea its health benefits?

It must be noted that the benefits of Black tea are different from Green tea even though they are obtained from the same Camellia Sinensis plant. The difference in taste, colour, and its nutrient composition is due to the difference in the processing methods. While Green tea leaves go through least amount of fermentation and oxidation (which lets the processed tea leaves remain green), Black tea goes through complete oxidation (which turns the green leaves into brownish-black)

Black tea is dried and crushed and this allows the action of enzymes to become rapid. These enzymes present in green leaves convert catechins (which are present in huge quantity in green leaves) to complex forms known as theaflavins and thearubigens. The process leads to the conversion of catechins into tannins which are responsible for the colour and flavour of Black tea.

Black tea for dental health

Black tea is rich in polyphenols and various studies and research have found out about the role of polyphenols in maintaining good dental health. This happens as they reduce the formation of plaque and restricts the growth of bacteria that are known to cause tooth decay and cavities. These polyphenols are capable of killing such bacteria that cause the sticky materials and sugary stuff to bind to our teeth leading to tooth decay. Hence, the benefit of Black tea definitely extends to maintaining good oral health.

Black tea for the health of the heart

Daily tea consumption of tea is known to lower the risk of having a heart attack and to improve the chances of surviving after having a heart attack. While there are reports that strongly support for Black tea’s potential to contribute to heart health, even Green tea has its own benefits for the heart.

The difference between the impact of Green tea and Black tea on the heart’s health also lies in their chemical composition. Most of the polyphenols that are present in Green tea are in the form of flavonoids. These flavonoids are specifically known as catechins. Catechins are chemicals responsible for Green tea’s heart-healthy properties.

On the other hand, Black tea does not have as many polyphenols as its green counterpart. But they have a unique set of compounds called tannins. The changes in its polyphenols during the oxidation process produce a set of tannins that have their own heart-health benefits. The polyphenols and manganese present in Black tea reduce the risk of coronary heart diseases by helping the cardiac muscle function. According to Boston’s School of Medicine, it even reverses the abnormal functioning of blood vessels responsible for strokes and other cardiovascular conditions.

Black tea for controlling cholesterol levels

There was a study conducted by the American Heart Association in New Orleans to understand how drinking Black tea affects the bad cholesterol levels of people who consume them. The bad cholesterol is responsible for heart strokes and fatal attacks. The study concluded that the people who drink 3 to 4 cups of Black tea every day are at a lower risk for heart problems than those who consume minimal amounts or no tea at all.

Black tea is also known to be effective in decreasing the level of triglycerides. It can reduce LDL or bad cholesterol, thus reducing the risk of heart disease. Drinking several cups of Black tea also improves the overall functioning of the arteries as components present in Black tea do not allow cholesterol to build up inside them. The overall boost in the body’s antioxidant levels is also beneficial in reducing cholesterol levels.

Black tea for preventing cancer

The catechins and polyphenols present in Black tea are known to prevent some forms of cancer. They block the DNA associated with tobacco and other toxic chemicals. It is also known to prevent breast cancer in women who are in pre-menopausal phase by raising the globulin hormones. The chances of ovarian cancer are also reduced as Black tea prevents the growth of cisplatin-resistant ovarian cancer cells. The component the theaflavins play an important role in preventing the damage done by harmful cells by destroying them.

Other study conducted over 58000 men explored the effects of Black tea on prostate cancer and concluded that the chances of developing early-stage prostate cancer were heavily reduced.

Polyphenols present in Black tea prevent the formation of harmful carcinogens in body and TF-2 specifically helps in undergoing apoptosis (a process which kills cancer cells while keeping the normal cells in their original state). In this way, Black tea prevents the formation of malignant tumours.

Black tea for preventing diabetes

Studies have revealed that people who have Black tea regularly (about one or two cups every day) have 70 per cent lower chances of developing Type 2 diabetes.

Type 2 diabetes occurs when there is insulin resistance in the body and Black tea helps by increasing overall insulin sensitivity. Also, high blood pressure is harmful to anyone with diabetes as it increases the overall risk. Here, tea plays an important role in regulating blood pressure. Another great advantage of drinking Black tea is that blocks the enzyme that turns starch into glucose and slows down the overall absorption of sugar in the small intestine.

Black tea for digestion and relieving an upset stomach

Black tea is rich in tannins and other chemical compounds that have a positive and relaxing effect on the digestive system of the human body. These tannins present in Black tea also have a helpful astringent effect on the intestinal lining. This helps in calming inflammation in the intestines and get the diarrhoea under control. These anti-inflammatory qualities of Black tea are also helpful for curing digestive disorders and relieving an upset stomach.

The polyphenol compounds and tannins have the ability to inhibit some types of bacteria which are harmful to our gut’s health. In addition, the non-polymeric phenolic compounds are absorbed by the gastrointestinal tract and they make these bacteria-killing components of Black tea orally active so that they can help in getting rid of harmful bacteria quickly.

When consumed with honey, Black tea is also been shown to specifically kill H. Pylori bacteria, which prevents symptoms of an H. Pylori, infection including ulcers.

Black tea for managing stress levels

Relief from stress is one of the best benefits of Black tea. While coffee is known for getting some people a little too energetic due to its high caffeine content, tea is a more balanced caffeine source as its caffeine levels are relatively low as compared to coffee.

It is also a relaxation beverage that can work as an overall stress reliever. Some research and studies have found out that Black tea can helps its drinkers recover from daily stress in life by lowering the stress hormone cortisol.

However, it is not just the caffeine content that is responsible for relief from stress, but rather the overall composition of Black tea with all its other compounds that create a positive impact. This was found through a study in which 75 healthy male tea drinkers with an average age of 33 were split into two groups. For six weeks, one group consumed a fruit-flavoured caffeinated Black tea mixture containing the active ingredients as found in a cup of tea while the other group drank a beverage that tasted the same and had the same level of caffeine yet did not contain any other active tea components.

The subjects then underwent stress-inducing situations similar to what experience in their daily life while the researchers kept a track of their stress hormones and blood pressure levels.

It was found that the tasks were stress-inducing according to all of the monitored health variables, yet 50 minutes after the stressor took place, the real Black tea-drinking group experienced a lowering of their cortisol levels that were significantly lower in comparison to the fake Black tea drinkers.

The real Black tea consumers also felt a sense of relaxation after the stressful event as compared to the fake group. The study also revealed that the Black tea drinkers had lower blood platelet activation which is useful for heart’s health and preventing a heart attack.

The low amounts of caffeine (as compared to coffee) promote the blood flow in the brain, without stimulating the heart, and improve mental alertness and concentration. L-theanine, an amino acid found in the Black tea helps you relax and concentrate fully on the tasks at hand.

The caffeine in Black tea is also known to boost memory and help in preventing Parkinson’s disease.
