What is Black Tea?

Black tea is no doubt one of the most popular types of tea enjoyed by a lot of people in different parts of the world. Black tea is the traditional tea of the West and therefore majority of the teas found in Western countries are black tea. This is partly because unlike white and green tea, black tea has a longer shelf life and it retains its flavor several years after its production.

Black tea is derived from Camellia Sinensis, a type of plant from which other teas like green tea, white tea and oolong tea is derived. Besides its long shelf life, black tea is different from white and green teas in other ways. Unlike these two types of tea, black tea is fermented. Oolong tea on the other hand is partially fermented. Black tea is also more oxidized than these three other types of teas. The oxidation process of black tea gives it its dark color and strong flavor.

The caffeine content in black tea is also higher than that of white tea, oolong tea and green tea, although, its caffeine content is lower to that found in coffee. The amount of caffeine in a cup of black tea depends on the particular type of tea. Black teas that are blended with spices and flavors that do not contain caffeine would have less caffeine than unblended black teas.

Generally, a cup of black tea contains about 50-90 mg of caffeine. There are different varieties of tea under the black tea category that offer bold, rich taste as well as a number of health benefits.

Benefits of Black Tea

A cup of black tea

Black tea is rich in nutrients. If drinking a cup of black tea every morning is a ritual for you, you should know that it’s a ritual worth sticking to for as long as you live. Black tea has a number of amazing health benefits and you can never go wrong with it if you take your tea in moderate amounts.

Some of the nutrients in black tea include protein, amino acids, dietary fiber, calcium, fluoride, omega-3 fatty acids, omega-6 fatty acids, potassium, manganese, carbohydrates and minerals. Black tea is naturally rich in antioxidants. The main sources of antioxidants in black tea are groups of polyphenols, including theaflavins, catechins and thearubigins.

Antioxidants are compounds that prevent oxidation, a chemical reaction that can produce free radicals, resulting to chain reactions that can destroy healthy cells in the body. Antioxidants work by preventing or slowing down damage to healthy body cells caused by free radicals. As the body processes the food you eat, free radicals, which are waste substances, are produced.

These free radicals are not meant to stay in the body. If the body is unable to get rid of them, they pair and this can cause oxidative stress. Oxidative stress can lead to damage to DNA, cells and proteins.There is an association between free radicals and aging. It is also linked to other diseases like cancer, stroke, arthritis, heart disease, Parkinson’s and Alzheimer’s diseases.

One of the major side effects of smoking is its ability to generate free radicals in the body. In the same way, one of the effects of alcohol in your body is the generation of free radicals. High consumption of fried foods and pesticides are other examples of substances that generate free radicals. Including black tea in your diet is a sure way to improve your health as the antioxidants in them can help to neutralize free radicals in your body.

With time, a person diagnosed with Parkinson’s may have difficulty talking and walking. They may also experience constant fatigue and sleep problems.

The compounds in black tea help to prevent the formation of carcinogens, substances capable of causing cancer. Types of carcinogens include viruses, pollution, some types of drugs, tobacco smoke and ultraviolet radiation from the sun. Carcinogens work either by damaging the DNA in cells or by causing inflammation.

Inflammation can lead to cells dividing at a fast rate, and when this occurs, there is a likelihood that cancer may develop. Some studies show that the compounds in black tea may help to prevent the growth and formation of malignant tumors and destroy cancer cells in the body without affecting healthy, normal cells.

Black tea interacts with some medications and it can lead to unpleasant side effects when taken with these drugs. Drinking black tea with some type of drugs or supplements can make the caffeine in black tea stay in your body longer than it should, and this is not good.

Black tea should not be taken with medications containing magnesium or calcium, for example.
